Executive Summary

The Villeneuve–Calahoo Sand and Gravel Extraction Area Structure Plan (ASP) is an area in Sturgeon County (the County) within Tp 054, R 26 to 28, W4M and Tp 054, R 01, W5M.

Hydrogeological Consultants Ltd. (HCL) was retained by the County to monitor groundwater levels and groundwater quality within the ASP, and to present and review the data as part of a groundwater monitoring report associated with the activities of the sand and gravel extractions in the area.

Water-level and chemical-quality data indicate that there have been some changes in the hydrogeological conditions of the sand and gravel aquifer in the Villeneuve–Calahoo Sand and Gravel Extraction ASP since 2004.

There have been two noteworthy trends in groundwater quality in the ASP; both trends are local and are related to only three monitoring wells. One change is related to an increase in the sulfate concentrations in the groundwater from two monitoring wells, MW04-03 and MW18-01, in the southeastern part of the ASP. The second change is an increase in the chloride concentration in the groundwater from MW14-02 in the northwestern part of the ASP.

The groundwaters from five monitoring wells have uranium or arsenic concentrations that exceeded the drinking water-quality guidelines in 2019. The monitoring wells with elevated arsenic concentrations are clustered in the north-central part of the ASP; the monitoring wells with elevated uranium concentrations are in the central and southeastern parts of the ASP. The uranium and arsenic concentrations do not show an increasing or decreasing trend.

At this time, there is no evidence that pit activities are resulting in any changes to the groundwater quality within the ASP.

There has been a noteworthy decline in the water levels in the western part of the ASP in close proximity to the active mining area. In MW11-02, there has been a water-level decline of slightly more than 10 metres since 2015. Significant declines have also been observed in A-S&G (OV), C-S&G (OV), and MLM.

The groundwater monitoring program has continued for several years, and there have been no seasonal changes in groundwater quality. Therefore, it is recommended that groundwater samples for both dissolved metals and routine chemical parameters be collected only once per year in late-spring/early summer.

The water-level monitoring is very helpful in assessing the impacts of gravel extraction on the water level in the sand and gravel aquifer; the water-level monitoring should be reviewed annually and adjusted as necessary. It is also recommended that consideration be given to strengthening the water-level program by the use of data loggers in current and future mining areas to provide a more complete record of the water level in the aquifer.

1.2. Scope

The present program included the processing of water-level data provided by the County; semi-annual collection of groundwater samples for chemical and physical analysis1; analysis and interpretation of the hydrogeological data; preparation of a report; and presentation of the results at a gravel committee meeting. The report includes basic data collected as part of the present program and documents the collection, synthesis, and interpretation of the data.

The Terms of Reference for the groundwater monitoring program are included in Appendix A. Schedule B of the Terms of Reference lists 21 monitoring wells (MWs) that are to be included as part of the present monitoring report. Addendums to Schedule B resulted in the replacement of one monitoring well and the addition of two monitoring wells as follows, for a total of 23 monitoring wells2:

 MW07-4-14, referred to in Schedule B, was replaced by MW10-01 in June 2010.  MW05-01 and MW18-01were added to the groundwater monitoring program in 2018.

1 Semi-annual groundwater samples were to be collected from 23 monitoring wells; the spring samples were analyzed for routine parameters only, and the fall samples were analyzed for routine parameters and dissolved metals. 2 MW11-01 is referenced as a monitoring well in the Terms of Reference, but no water-level measurements or groundwater samples have been collected from MW11-01 because it is dry. MW11-01 is not included in Appendix B of the present report.

2. Methodology

2.1. Existing Data Sources

2.1.1. Maps and Aerial Imagery

The map reference used is the 1:250,000 National Topographic Series map sheet, with local detail available from the 1:50,000 map sheet.

Digital ortho-imagery is obtained from various websites, depending on the detail available for the area of study (AOS).

2.1.2. Data from Government Sources

2.1.2.1.1. Alberta Water Well Information Database

The Alberta Water Well Information Database3 includes water well records prepared by water well drillers, water wells identified during various field programs with little or no information, and boreholes with varying amounts of information. The database also includes groundwater-quality information from before 1988 for groundwaters from some water wells. Data collected since 2006 as part of the Baseline Water Well Testing Program are in the Alberta Water Well Information Database.

Many of the records in the Alberta Water Well Information Database have horizontal spatial control based on a land location rather than a point location, and there is very little quality control related to the verification of the land location. Historically, the most commonly used designation is a quarter section, with an area of 640,000 square metres, and the horizontal coordinates given for the water well are the centre of the quarter section. More recently, horizontal coordinates are determined by the water well driller using a consumer-grade handheld GPS (global positioning system receiver).

2.1.2.1.2. Alberta Geological Survey

The Alberta Geological Survey (AGS) regional groundwater reports are referenced and various AGS shapefiles are used as required.

2.1.3. Data from Non-Government Sources

2.1.3.1. The Groundwater Centre Database

The Groundwater Centre (TGWC) database4 includes records for features that directly and indirectly relate to non-saline and saline groundwater.

The data in TGWC database that are related to non-saline groundwater are enhanced versions of the data in the Alberta Water Well Information Database. TGWC database for the AOS also houses hydrogeological data collected during the present program.

Unless more detailed information is available, the horizontal coordinates assigned to groundwater records are the centres of their reported legal locations.

Information in TGWC database has been used in the preparation of thematic maps and to determine regional aquifer parameters.

2.1.3.2. HCL Hydrogeology Database

HCL maintains a database of geologic units (geounits) for the geologically undisturbed part of the province. The database includes surface contours for the tops of individual geounits; these surfaces are used on cross-sections and various figures in this report.

2.1.4. Published and Unpublished Reports

The Bibliography in Section 8 of this report includes documents that relate to hydrogeology in the general area of the present project.

2.2. Collection of New Data

2.2.1. Groundwater Sampling

Groundwater samples are collected wearing fresh nitrile gloves for each sampling site. The sample bottle(s) are rinsed with the groundwater to be sampled, unless the sample bottle contains preservatives provided by the laboratory doing the analysis. When samples are collected, the sample bottles are filled to capacity with little or no air space remaining. If the analysis is for dissolved metals, samples are field filtered using a 0.45 micron in-line disposable filter.

Groundwater-quality parameters analyzed by a laboratory can include chemical, physical, and microbiological parameters, which may include the following: (1) Inorganic Non-Metallic; (2) Dissolved Metals; (3) Total Metals; (4) Microbiological; (5) Routine Water; and (6) Physical and Aggregate properties. The groundwater samples are stored in a cooler with ice packs for transport to the laboratory, which is accredited in Alberta to perform the requested analyses.

Field parameters (pH, temperature, and electrical conductivity) are measured after laboratory samples are collected.

The groundwater samples are collected according to the procedures outlined in the HCL field manual.

2.2.1.1. Sampling from Monitoring Well

The purging and groundwater sampling procedures are to be performed using a dedicated, a new, or a newly cleaned sampling device for each monitoring well.

The monitoring well is purged by removing three groundwater volumes from the monitoring well or by purging until there is no groundwater left in the monitoring well. When there is sufficient groundwater in the monitoring well after purging, the necessary groundwater samples are collected.

The monitoring well is pumped until the temperature of the discharging groundwater remains constant prior to the collection of groundwater samples.

2.3. Spatial Coordinates

Horizontal coordinates are based on a 10-degree Transverse Mercator projection, with the central meridian of 115 degrees west longitude, using NAD83 (North American Datum of 1983). Horizontal coordinates are determined for features identified in the field using a consumer-grade handheld GPS. Vertical coordinates are from the digital elevation model (DEM) provided by AltaLIS Ltd., the agent for Alberta Data Partnerships Ltd.

2.4. Measurements

Vertical measurements associated with the present report may have been recorded to two or more decimal places. However, most vertical measurements are provided in the report to one decimal place and may therefore not agree with the number of decimals presented in the appendices and in tables. The reference point for water-level measurements is the top of casing, and all water-level measurements are reported as metres below top of casing (BTOC) unless otherwise noted; most other vertical measurements are reported as metres below ground level (BGL).

2.5. Other

All gridding uses the Kriging method with a linear variogram model as provided in Surfer, a Golden Software program. Cross-sections are created using AutoCAD and, for illustrative purposes, are enhanced using CorelDRAW. Maps are created and analyzed in ArcGIS.

3.1. Maps and Aerial Imagery

The area of study is situated within the 83G and 83H 1:250,000 National Topographic Series map sheets, with local detail available from the 1:50,000 83G09 and 83H12 map sheets. Digital topographic control is from the 1:20,000 DEM prepared by AltaLIS Ltd.

Digital ortho-imagery for the present program was obtained from Lafarge Canada Inc. (Lafarge) and Google Inc.

3.2. General Hydrogeology

The regional groundwater assessment for Sturgeon County (HCL, 2001) shows the presence of a linear bedrock low identified as the Buried Onoway Valley in the southwestern part of the County. The Buried Onoway Valley mainly parallels the stretch of the present-day northwest from St. Albert to Calahoo and to the County border. The Buried Onoway Valley is 2 to 8 kilometres wide within the County, with local bedrock relief up to 60 metres. Sand and gravel deposits can be expected in association with this bedrock low, with the thickness of the sand and gravel deposits being generally less than 25 metres.

Figure 3 is a bedrock topography map showing that the Buried Onoway Valley underlies the northern and eastern portions of the ASP and is oriented in a northwest to southeast direction.

In the County, the upper bedrock includes the Horseshoe Canyon, the Bearpaw, and the Oldman formations, and the Birch Lake Member, which is part of the Foremost Formation. Figure 4 shows that the uppermost bedrock underlying the Buried Onoway Valley is the lower part of the Horseshoe Canyon Formation, which is comprised of mudstone, sandstone, and carbonaceous shale. The Buried Onoway Valley is shown on the left-hand side of the cross-section, which is in the southwestern part of the County. The Buried Onoway Valley is associated with deposits of sand and gravel that comprise a regional aquifer, which is a groundwater source for some residents in the Sturgeon County area. The base of the Buried Onoway Valley is approximately 40 metres BGL, an elevation of approximately 640 metres above mean sea level (AMSL).

Figure 5 on the following page is a hydrogeological map for the area showing that the thalweg of the Buried Onoway Valley (Thalweg) passes beneath the northern and eastern parts of the ASP. The map also shows that groundwater yields from water wells completed in the ASP are expected to vary from 5 to 650 cubic metres per day (m³/day). The locations of the 23 monitoring wells that are included as part of the present groundwater monitoring program are also shown in Figure 5.

Stantec Consulting Ltd. (Stantec, 2009) stated that the sand and gravel aquifer within the Buried Onoway Valley is overlain by a confining layer; in the western part of the ASP, the potentiometric surface is above the bottom of the confining layer, resulting in artesian conditions, while in the southeastern part of the ASP, groundwater levels are within the aquifer, indicating unconfined conditions.

3.3. Villeneuve–Calahoo Sand and Gravel Extraction ASP

County personnel have indicated that the practice for gravel companies within the Villeneuve–Calahoo gravel pit area is to remove all the gravel deposits once they are exposed. The typical geologic materials in the gravel areas are clay, underlain by sand deposits, gravel layers, and bedrock; an example of a typical pit wall is shown in Figure 7. A gravel pit generally encounters the top of gravel at an approximate depth of 9 metres BGL and the top of bedrock at an approximate depth of 18 metres BGL, although these depths can change significantly from one area to the next.

The County has also stated that reclamation is typically carried out after gravel from a pit has been extracted. The materials used for reclamation are the unused sand and Figure 7. Typical Pit Wall the clay strippings from the new pit. Once reclamation is completed, topsoil is spread onto the fields and the area is reclaimed as farmland, which is seeded and returned to the farmer; land that cannot be reclaimed is converted into lakes or ponds.

In areas where the bottom of the aggregate is below the top of the saturated zone, dewatering of pits is required for extraction. By employing a pit-to-pit dewatering scheme, the loss of groundwater is restricted to evaporation from pits and the groundwater that adheres to the gravel that is being trucked off site. However, the replacement of the sand and gravel aquifer with a thinner layer of less permeable material has the potential to create mounding of the water-level surface in areas upgradient from the reclaimed areas. Therefore, the present groundwater monitoring program has four main purposes:

 To determine the local drawdown effects of dewatering  To determine the extent of groundwater mounding in upgradient areas  To determine whether the extraction and reclamation process is affecting groundwater quality  To determine if sand and gravel extraction is affecting local groundwater users

3.4. Groundwater Monitoring Well Network

The current groundwater monitoring well network includes 23 monitoring wells that are completed in the Buried Onoway Valley sand and gravel deposits within the ASP. The monitoring wells in the MW01 series were installed in 2001 in support of a lower sand and gravel groundwater assessment (UMA, 2001). MW04-01 and MW04-02 were installed in 2004 on behalf of Yellowhead Aggregates (Westerra, 2004a). MW04-03 was installed in 2004 on behalf of Lafarge (Westerra, 2004b). MW05-01 was completed in 2005 on behalf of Inland Aggregates Ltd. (Inland). A-S&G (OV) and C-S&G (OV) were installed in 2007 in support of the Calahoo Bog Groundwater Study (Westwater, 2007). The monitoring wells in the MW07 series were installed in 2006 and 2007 under the direction of Stantec (2008). MW10-01 was drilled in 2010 on behalf of the County. MW11-01 and MW11-02 were drilled in 2011 on behalf of Inland. MW14-01 and MW14-02 were installed in 2014 on behalf of the County. MW18-01 was drilled in the summer of 2018 on behalf of Lehigh. The MLM site is from the 1980s; very little completion information is available for this monitoring well. Additional groundwater monitoring programs, which include several landowner water wells, are conducted by HCL on behalf of other companies in the area6.

Monitoring well details are in Appendix B.

4.2. Water-Level Monitoring

HCL personnel measured the water levels in 22 monitoring wells during the site visits in the spring and fall of 2019; a water level in MW11-01 was not measured because it is dry. Water levels were measured to the nearest centimetre using a water-level tape from the top of the monitoring well casing. Data loggers are installed in six of the 23 monitoring wells, as shown in Table 2. The data loggers are programmed to record a water-level measurement every hour. Figure 9 on the following page identifies the monitoring wells within the ASP that are equipped with data loggers.

HCL personnel measured the water levels in metres BTOC; Table 3 displays the water levels in metres BGL, calculated by subtracting the casing stick-up from the water level in metres BTOC. For the monitoring wells that were not surveyed, the water-level elevations in metres AMSL were calculated by subtracting the depth to water in metres BGL from the ground elevation determined from the 1:20,000 DEM prepared by AltaLIS Ltd. Semi-annual water levels measured by County personnel were submitted to HCL and have been entered into TGWC database. Hydrographs for each monitoring well are in Appendix B.

Of the 23 sites shown in Table 3, the water levels at all but four sites rose between May and November 2019. These water-level rises ranged from 0.05 to 2.11 metres. The water levels at the remaining sites were lower in the fall than in the spring; the average water-level decline was 0.24 metres. Between 2015 and 2018, a significant water-level decline of 2 to 10 metres was observed in the following six monitoring wells: A-S&G (OV), C-S&G (OV), MLM, MW05-01, MW07-2-14, and MW11-02. In 2019, all but MW05-01 showed a rise in water level. These monitoring wells are all situated in the west-central part of the ASP near the active pit areas.

4.3. Groundwater-Quality Monitoring

Groundwater samples from the monitoring wells were collected during the site visits in the spring and fall of 2019. As standard protocol, HCL personnel performed the following during every sampling event:

 Inspection of monitoring well  Purging of monitoring well  Collection of a groundwater sample  Storage and transportation of the groundwater sample to the laboratory

Sturgeon County, 2019 Groundwater Monitoring Report 13 Villeneuve-Calahoo Gravel Extraction Area, Tp 054, R 26 to 28, W4M and Tp 054, R 01, W5M, MR-0224.19

During HCL’s initial inspection of each monitoring well, the coordinates were determined using a consumer-grade handheld GPS, the diameter and material of the casing were noted, the monitoring well was photographed, and the total depth and casing stick-up were measured. During every site visit, the condition of each monitoring well was inspected, and additional information was collected if deemed necessary; for example, if damage was noted, the monitoring well was photographed again, and the casing stick-up and total depth were re-measured.

For sample collection, the monitoring well was purged of the stagnant water with a bailer or Waterra tubing until at least three monitoring well volumes of groundwater had been removed, the monitoring well was purged dry, or the groundwater being removed from the monitoring well had measured field parameters that were consistent.

The groundwater samples collected in the spring of 2019 were analyzed for routine parameters only; the groundwater samples collected in the fall of 2019 were analyzed for routine parameters and dissolved metals. During both the spring and fall sampling events, all monitoring wells were sampled on the same day that they were purged. All groundwater samples were analyzed by Element Materials Technology Inc.

4.3.1. Groundwater Quality

All available groundwater-quality data for each monitoring well have been entered into TGWC database. The 2019 chemical analysis results for the groundwater from each monitoring well are in Appendix B. Groundwater-quality parameters of particular interest are discussed briefly in the following sections.

Figure 10 is a Piper tri-linear diagram showing the groundwater quality for samples collected in the spring of 2019. The diagram shows that most of the groundwater samples are classified as calcium-bicarbonate-type waters, which are typical of groundwaters from aquifers within the surficial deposits, although there is a range in water quality from a calcium type with no dominant anion to a bicarbonate type with no dominant cation.

Figure 10. Spring 2019 Piper Tri-Linear Diagram

In general, groundwater-quality parameters for samples collected in 2019 remain within historical ranges, with the exception of MW04-01 and MW04-02; the groundwaters from these two monitoring wells were classified as calcium-bicarbonate-type waters in the early 2000s, calcium-sulfate-type waters beginning in 2011, and are currently classified as calcium-type waters with no dominant anion. Figure 11 is a Piper tri-linear diagram showing the groundwater quality for samples collected from MW04-01; the Piper tri-linear diagram for MW04-02 is not shown but displays a similar range.

4.3.2. Chloride

Chloride concentrations in 2019 ranged from 0.4 to 9.3 milligrams per litre (mg/L) for all monitoring wells except MW04-03 and MW14-02, which have had consistently higher chloride concentrations than the other monitoring wells since groundwater sampling began7.

Chloride concentrations in the groundwater samples collected from MW04-03 in the spring and fall of 2019 were 24.8 and 17.2 mg/L, respectively; the historical high for chloride in this monitoring well is 104 mg/L, which occurred in the spring of 2004. Since 2016, there has been a decreasing trend in the chloride concentration in the groundwater from MW04-03, from 96 to 17.2 mg/L.

Chloride concentrations in the groundwater samples collected from MW14-02 in the spring and fall of 2019 were 73.7 and 133 mg/L, respectively. Since 2015, there has been an increasing trend in the chloride concentration in the groundwater from MW14-02, from 13 to 133 mg/L.

No groundwater sample from any of the monitoring wells has ever exceeded the aesthetic objective (AO) of 250 mg/L for chloride (Health Canada, 2019).

7 Groundwater sampling from MW04-03 and MW14-02 began in 2004 and 2015, respectively.

4.3.3. Nitrate

The maximum acceptable concentration (MAC) for nitrate in drinking water based on health objectives is 10 mg/L (Health Canada, 2019). In the spring of 2019, the nitrate concentration was below 0.01 mg/L in the groundwater samples from 15 of the monitoring wells; the highest concentration of nitrate was 3.78 mg/L in the groundwater from MW04-03. In the fall of 2019, the nitrate concentration was below 0.01 mg/L in the groundwater samples from 15 of the monitoring wells; the highest concentration of nitrate was 3.21 mg/L in the groundwater from MW01-01.

4.3.4. Sulfate

The AO for sulfate is 500 mg/L (Health Canada, 2019). Sulfate concentrations ranged from 45.1 to 550 mg/L in the groundwater samples collected in the spring of 2019 and ranged from 52.6 to 517 mg/L in the groundwater samples collected in the fall of 2019. The two sulfate AO exceedances were in the groundwater samples collected from MW04-01.

4.3.5. Total Dissolved Solids

The AO for total dissolved solids (TDS) is 500 mg/L (Health Canada, 2019). TDS concentrations ranged from 491 to 1,180 mg/L in the groundwater samples collected in the spring of 2019 and ranged from 495 to 1,130 mg/L in the groundwater samples collected in the fall of 2019. In the spring 2019, all but two of the samples (MW01-04 and MW04-02) had TDS concentrations that exceeded the AO. In the fall of 2019, only one sample (MW04-02) had a TDS concentration that was below the AO.

4.3.6. Electrical Conductivity

Electrical conductivity values ranged from 791 to 1,570 microsiemens per centimetre (S/cm) for the groundwater samples collected in the spring of 2019 and ranged from 818 to 1,560 S/cm for the groundwater samples collected in the fall of 2019.

4.3.7. Dissolved Metals

The groundwater samples collected from the monitoring wells in the fall of 2019 were analyzed for dissolved metals. The results indicated that the concentrations of uranium, arsenic, and manganese in the following groundwater samples exceeded the MACs for health objectives:

 Uranium (0.02 mg/L) in MW01-03 (0.0306 mg/L), MW01-07 (0.0233 mg/L), and MW04-03 (0.0308 mg/L)  Arsenic (0.01 mg/L) in MW07-2-14 (0.0114 mg/L) and MW14-01 (0.0113 mg/L)  Manganese (0.12 mg/L) in all monitoring wells except MW01-01, MW01-03, MW04-01, and MW04-03 in the spring of 2019 and MW01-01, MW01-03, MW04-01, MW04-03, and MW11-02 in the fall of 2019.

Dissolved metals were first analyzed during the November 2010 sampling event. The uranium concentrations in MW01-03 and MW04-03 have historically been above the MAC of 0.02 mg/L, while MW01-07 has historically been below the MAC. The arsenic concentration in the groundwater from MW07-2-14 has historically been above the MAC of 0.01 mg/L, while the arsenic concentration in the groundwater from MW14-01 has only exceeded the MAC since the fall of 2018. In 2019, Health Canada established a MAC of 0.12 mg/L for manganese (Health Canada, 2019). The manganese concentrations have historically been above the MAC in the groundwaters from all monitoring wells except MW01-01, MW01-03, MW04-01, and MW04-03. There is no noteworthy trend in manganese concentration throughout the ASP.

The results for the spring of 2019 sampling event indicated that the iron concentrations exceeded the AO of 0.3 mg/L in all of the groundwater samples except for MW04-01, MW04-02, and MW04-03. The results for the fall of 2019 sampling event indicated that the iron concentrations exceeded the AO in all groundwater samples except for C-S&G (OV), MW04-02, and MW04-03.

The results for the spring of 2019 sampling event indicated that the manganese concentrations exceeded the AO of 0.05 mg/L in all of the groundwater samples except for MW01-03 and MW04-03. The results for the fall of 2019 sampling event indicated that the manganese concentrations exceeded the AO in all of the groundwater samples except for MW04-01 and MW04-03.

None of the above exceedances exhibit a noteworthy trend.

5. Interpretation

5.1. Water Levels

Reports prior to the 2018 groundwater monitoring report have discussed significant water-level trends based on water levels measured before 2019. The focus of the present report is to discuss the relevance of water levels measured in 2019 relative to historic levels.

Based on a review of the water levels measured in 2019 and the reported sites of pit activity, the 22 monitoring wells8 that have measurable water levels can be arranged into five groups, as shown in Figure 12:

 Group 1 consists of A-S&G (OV), C-S&G (OV), MLM, MW01-06, MW05-01, and MW11-02.  Group 2 consists of MW01-04, MW01-05, MW14-01, and MW14-02.  Group 3 consists of MW01-03, MW01-07, MW01-08, and MW07-2-14.  Group 4 consists of MW07-1-33 and MW07-3-33.  Group 5 consists of MW01-01, MW04-01, MW04-02, MW04-03, MW10-01, and MW18-01.

Sturgeon County, 2019 Groundwater Monitoring Report 18 Villeneuve-Calahoo Gravel Extraction Area, Tp 054, R 26 to 28, W4M and Tp 054, R 01, W5M, MR-0224.19 Group 1 is in the western portion of the ASP in the 687 vicinity of the Calahoo bog and active gravel pits 686 operated by Lafarge and Lehigh. Figure 13 shows 685 that the majority of the water levels in the Group 1 684 C-S&G(OV) MW11-02 monitoring wells have risen since 2018. Some of the 683 monitoring wells have earlier water-level recoveries 682 than others, corresponding with shorter distances to A-S&G(OV) 681 reclaimed areas. MLM and MW05-01 show a MW05-01 680 MW01-06 water-level decline throughout 2018 and 2019, which 679 coincides with mining activities by Lehigh, reflecting MLM 678 dewatering activities in the western part of 27-054-27 W4M; based on the water levels, the dewatering 677 began in 2013. MLM has had a water-level rise in the 676 last half of 2019. A-S&G (OV), C-S&G (OV), and 675 MW11-02 show a continued recovery in water 674 levels since late 2018, which reflects the reclamation 673 in the NE 29-054-27 W4M that Lafarge had 672 completed in 2018, the reclamation in the north half 671 of 28-054-27 W4M that took place in 2019, and the 2005 2010 2015 2020 start of reclamation by Lehigh in the southeastern Figure 13. Group 1 Hydrograph corner of 28-054-27 W4M. With the exception of MW07-2-14 (a Group 3 monitoring well), only the Group 1 monitoring wells have shown a declining water-level trend in recent years.

Group 2 is in the northwestern portion of the ASP, where water levels recorded in the monitoring wells have not changed significantly over the historical record. These monitoring wells are likely not affected by mining activities, as the active pits and reclamation sites are more than 740 metres downgradient from the four monitoring wells. Figure 14 shows that the Group 2 monitoring wells have an overall horizontal water-level trend, superimposed with seasonal water-level fluctuations of approximately one metre.

Figure 14. Group 2 Hydrograph

Sturgeon County, 2019 Groundwater Monitoring Report 19 Villeneuve-Calahoo Gravel Extraction Area, Tp 054, R 26 to 28, W4M and Tp 054, R 01, W5M, MR-0224.19

Group 3 is in the central portion of the ASP, which contains mainly reclaimed pits. Water levels in the Group 3 monitoring wells have fluctuated in the past, which reflects dewatering activities when the nearby pits were active. Figure 15 shows that the water levels in MW01-07 and MW01-08 have similar trends and have remained fairly constant since 2012, at an elevation that is approximately 3 metres higher than the measured water levels in the early 2000s. The mainly horizontal water-level trend since 2012 indicates that natural processes have likely taken over the water-level variations. The higher water levels since 2012 may be a result of groundwater mounding upgradient from the nearby reclaimed pits, or because the water-level monitoring began after active dewatering had already commenced, or a combination of both factors.

The water level in MW01-03 has risen more than 3 metres since late 2017, which is likely a result of dewatering from active pits into the pond that is Figure 15. Group 3 Hydrograph approximately 500 metres north of MW01-03.

Water levels in MW07-2-14 have risen since June 2018, when dewatering ceased nearby, causing the water levels to recover. MW01-07 and MW01-08 are east of the Schafers 240 Pit and are situated on either side of a pond. The slow and steady water-level rise in MW01-08 since 2017 is likely due to recharge from the Schafers 240 Pit and the hydraulically connected pond. The similar but delayed water-level rise in MW01-07 is likely due to the greater distance between the monitoring well and the Schafers 240 Pit.

Group 4 is in the northeastern region of the ASP. Water levels in this area have been on a slow recovery trend since 2016. Figure 16 shows that the water levels in MW07-1-33 and in MW07-3-33 have risen by 0.58 metres and 1.27 metres, respectively, since the fall of 2017, which may be a result of the reclamation of previously active pits south of the two monitoring wells. MW07-1-33 and MW07-3-33 are downgradient from the reclaimed pit sites and may be experiencing recovery of water levels. The water-level decline from 2008 through 2010 indicates historical mining events and associated dewatering of pits in the area. The two monitoring wells are at the farthest monitored sites downgradient from the mining activities, and therefore show the slowest water-level recovery since the cessation of dewatering in the nearby reclaimed pits.

Figure 16. Group 4 Hydrograph

Group 5 is in the southeastern portion of the ASP. Similar to the northwestern portion of the ASP, water levels for the monitoring wells in this area have shown little change over the past year. Water-level fluctuations in MW04-01 in 2007 and 2017 are possibly due to reference-point inaccuracies when the measurements were taken. Due to errors in the data, the highs in 2007 and 2017 may be ignored, leaving the data set to follow the historical and the MW04-02 water-level trends more closely.

Figure 17 generally shows the stable nature of the water levels in the Group 5 monitoring wells in 2019, indicating natural fluctuations in the water table and coinciding with the lack of activity in the area throughout 2019. The hydrograph for the Group 5 monitoring wells is broadly similar to the Group 3 hydrograph in that most of the water-level variations have occurred in the past, when there was active pit dewatering in areas that have since become reclaimed pits. The reclamation of the pits is evident in the reasonably horizontal water levels since 2012.

Based on the review of water levels and reported pit activity, recently recorded water-level rises are a result of the cessation of nearby gravel extraction. Recent and historical water-level declines are mainly a result of nearby dewatering during mining operations. Temporary drawdown near active dewatering pits can be in the order of 4 metres; Figure 17. Group 5 Hydrograph water-level recovery is expected after the cessation of dewatering, although full recovery may take several years.

Figure 18 on the following page shows the contoured water-level change in the ASP, which is calculated by subtracting the “natural” water levels, based on the water levels measured in 2004, from the water levels measured in 2019. Although it should be kept in mind that the “natural” historical water levels can be subjective and may be misleading at times if the monitoring site was situated near pits that were active in 2004, the map does show a regional characteristic believed to represent current water-level conditions in the sand and gravel aquifer. The water-level decline centred on MLM in the western part of the ASP is associated with nearby active pits in 2019. The water-level mounding in MW05-01, which is east of the active pits, may be a result of dewatering into a recharge pond, mounding effects caused by MW05-01 being upgradient from the reclaimed pit area, or a combination of both processes.

Figure 18. Contoured Water-Level Change (2019)

The water-level data show that there can be temporary water-level changes in the sand and gravel aquifer associated with pit activities, but the magnitude of change is generally localized to be within a few hundred metres of pit activities and typically does not represent an adverse effect on local groundwater users, unless significant dewatering occurs in close proximity to a shallow residential water well. However, there can also be a natural fluctuation in measured water levels that is associated with fluctuations in aquifer recharge from precipitation.

5.2. Groundwater Chemistry

A review of the groundwater-quality data collected from the monitoring wells in 2019 shows that the southeastern part of the ASP is an area where there are elevated concentrations of chloride, nitrate, sulfate, and TDS, as observed in the groundwaters from MW04-01, MW04-03 and MW18-01.

The groundwater from MW14-02 has shown a steady increase in chloride concentration since 2015, while the groundwater from MW04-03 has shown a steady decrease in chloride concentration since 2016. In 2019, the chloride concentration in the groundwater from MW14-02 rose from 73.7 mg/L during the spring sampling event to 133 mg/L during the fall sampling event. Further investigation is required to understand the sudden increase in chloride concentration at this site. The increasing chloride concentration in the groundwater from MW14-02 may be associated with road salt used nearby. Because there are no aggregate extraction activities taking place within several kilometres of the ASP, the chemical analysis results are considered to represent baseline conditions.

The data show a correlation between sulfate and TDS concentrations, but no trends or relationships are evident when comparing the concentrations of any of these parameters to water-level highs and lows or to the group in which monitoring wells belong.

Figure 19 is a map of sulfate concentrations based on the fall of 2019 analyses and shows that sulfate concentrations in the ASP range from 52.6 to 517 mg/L. Concentrations are elevated in the southeastern portion of the ASP, within the area of MW04-01, MW04-03, and MW18-01, and range from 330 to 517 mg/L. The groundwater from MW04-01 has shown a large increase in sulfate concentration since 2018. The lowest sulfate concentrations range from 52.6 to 61.5 mg/L and are in the north-central portion of the ASP. Gravel dewatering and extraction activities have not caused any changes in the sulfate or chloride concentrations in the groundwaters; these changes may be naturally occurring or related to other activities, such as agriculture or road maintenance.

At this time, there is no evidence that pit activities are resulting in any changes to the groundwater quality within the ASP.

6. Conclusions

Water-level and chemical-quality data indicate that there have been some changes in the hydrogeological conditions of the sand and gravel aquifer in the Villeneuve–Calahoo Sand and Gravel Extraction ASP since 2004.

There have been two noteworthy trends in groundwater quality in the ASP; both trends are local and are related to only four monitoring wells: MW04-01, MW04-03, MW14-02, and MW18-01. One change is related to an increase in the sulfate concentrations in the groundwaters from these three monitoring wells in the southeastern part of the ASP. The second change is an increase in the chloride concentration in the groundwater from MW14-02 in the northwestern part of the ASP. Gravel dewatering and extraction activities have not caused any changes in the sulfate or chloride concentrations in the groundwaters; these changes may be naturally occurring or related to other activities, such as agriculture, water softeners, or road maintenance.

The groundwaters from five monitoring wells have uranium or arsenic concentrations that exceeded the MACs in 2019. Uranium and arsenic are naturally occurring elements derived from parent material and not from gravel extraction operations; their concentrations in the groundwaters do not show an increasing or decreasing trend. The groundwaters from all monitoring wells except MW01-01, MW01-03, MW04-01, MW04-03, and MW11-02 had manganese concentrations that exceeded the MAC in 2019. These groundwaters have historically been above the MAC and AO, and the elevated concentrations are not due to gravel extraction but represent naturally occurring or background conditions.

At this time, there is no evidence that pit activities are resulting in any changes to the groundwater quality within the ASP.

There has previously been a noteworthy decline in the water levels in the western part of the ASP in close proximity to the active mining area. In MW11-02, there has been a water-level decline of slightly more than 10 metres since 2015. Significant declines have also been observed in A-S&G (OV), C-S&G (OV), and MLM. However, in 2019, decreased pit activity in the western part of the ASP has resulted in water-level recoveries in these monitoring wells of 0.5 metres to more than 2 metres. The water-level data show that there can be temporary water-level changes in the sand and gravel aquifer associated with pit activities, but the magnitude of change is generally localized to be within a few hundred metres of pit activities and typically does not represent an adverse effect on local groundwater users. In addition to water-level fluctuations caused by gravel extraction activities, there can also be a natural fluctuation in measured water levels that is associated with fluctuations in aquifer recharge from precipitation.

7. Recommendations

The Sturgeon County groundwater monitoring program has continued for several years, and there have been no rapid changes in groundwater quality. Therefore, it is recommended that groundwater samples for both dissolved metals and routine chemical parameters be collected only once per year in late-spring/early summer.

The water-level monitoring is very helpful in assessing the impacts of gravel extraction on the water level in the sand and gravel aquifer; the water-level monitoring should be maintained. It is also recommended that consideration be given to strengthening the water-level program by the use of data loggers to provide a more complete record of the water level in the aquifer.

It is recommended that an annual review be made of the sites being monitored with data loggers, and that monitoring sites in low-risk areas far from current pit activities that do not require daily water levels as a condition of their approvals have their data loggers moved to sites where the more frequent water-level data would be more useful.

Because a consultant conducts site visits to download data loggers twice per year, it is recommended that the monthly site visits by the County be reduced from 12 to 10 times per year.

Sturgeon County, 2019 Groundwater Monitoring Report A - 2 Villeneuve-Calahoo Gravel Extraction Area, Tp 054, R 26 to 28, W4M and Tp 054, R 01, W5M, MR-0224.19 Introduction

The Calahoo Villeneuve Gravel Extraction Area is located in Sturgeon County approximately eleven to twenty kilometers West of the City of St. Albert.

The plan area extends from Range Road 262 in the East to Range Road 11 in the West and from Highway 633 in the South to Highway 37 in the North.

Background

The Calahoo - Villeneuve- area has one of the largest reserves of gravel in the Edmonton area. The area has been actively mined for the past 50 years. Recent requests to expand the area has resulted in a two year process to develop an Area Structure Plan for the orderly development of the gravel resources.

Copies of the Calahoo-Villeneuve Sand and Gravel Extraction Area Structure Plan are available online in the Sturgeon County website. Excerpts from recent groundwater studies relevant to this groundwater monitoring program are available for background information.

Purpose of Study

The purpose of the proposed study is to provide semi-annual testing of the existing groundwater monitoring wells. The monthly water levels will be recorded by Sturgeon County and supplied to the consultant for inclusion in the report. Interpretation on the impact on available groundwater quality and quantity is required. A report shall be generated from this information and the information provided by Sturgeon County.

Scope of Study

The scope of the study is also to complete semi-annual testing of the groundwater monitoring wells as identified on Map labelled Schedule A. The testing will include the quantity and quality of the groundwater in each well. A total of 21 wells approximately 15m in depth are to be tested.

A. Groundwater sampling and analysis is required as follows (New Wells to be added once installation is completed):

1) Routine parameters for 21 wells – two sampling events per year in May and November (Calcium, Magnesium, Sodium, Potassium, Carbonate, Bicarbonate, Sulphate, Chloride, Nitrate-Nitrite, Alkalinity, Hardness, Total Dissolved Solids, pH, and electrical conductivity)

Dissolved Metals testing for 21 wells – one sampling event each year in November.

2) Monthly water level data of 19 wells will be provided by Sturgeon County, and is to be compiled and included within the report. Wells A-S&G (OV) / C-S&G (OV) currently have data loggers installed, and consultant is required to download and incorporate information into annual report. Additional Data loggers are continually being implemented, so additional download

3) Interpretation of groundwater analysis results and monthly water level information is to be provided. Consultant is to provide comments on comparative groundwater quality and quantity within reclaimed areas, areas adjacent to active mining operations and areas yet undisturbed by mining operations. The impact, if any, of gravel mining on the local groundwater is to be quantified.

4) An annual report compiling the groundwater testing results and interpretation is to be provided prior to March 1 of the following year. Two (2) hard copies of the report and one digital copy of the report in a pdf compatible format to be provided. The consultant is expected to present results at a committee meeting of local residents, political leaders, gravel operators and Albert Environment representatives. The report will also be posted on Sturgeon County website to be made available to the public.

Summary of Proposed Tasks

A.1 Provide semi-annual testing of the existing ground water monitoring wells. A.2 Compile monthly water level readings provided by Sturgeon County A.3 Provide interpretation on groundwater monitoring results and gravel mining A.4 Prepare and present an annual report of the groundwater monitoring results.

Project Schedule

The project is expected to continue on a semiannual basis until either party provides thirty days notice to terminate the contract. The initial contract for this project is expected to last 2 years. Active Gravel Extraction Operations requiring long-term monitoring are expected to be in the area for the next 20 to 25 years.
