2012 Salmon Falls River TMDL Monitoring Report January 2013

1. INTRODUCTION FB Environmental Associates (FBE) has been conducting seasonal (summer) compliance monitoring for the Salmon Falls River Phased Total Maximum Daily Load (TMDL) on behalf of the municipalities of Somersworth and Rollinsford, New Hampshire, and Berwick and South Berwick, Maine, since 2006. This sampling effort targets low-flow summertime conditions, defined as <114 cfs measured at Milton Three Ponds Dam gauging station, in Milton, NH. For the first years of monitoring, samples were collected from the same five locations in accordance with the Maine Department of Environmental Protection’s (ME DEP) 2006 Salmon Falls River TMDL Work Plan. Additional stations were added in later years. In 2009, frequent rain precluded sampling, as typical low-flow summer conditions were generally absent. ME DEP deployed water quality datasondes at two locations along the impaired segment, and this year FBE checked the temperature and dissolved oxygen profile at each datasonde sites to ensure proper depth. ME DEP can be obtained by contacting Barry Mower at 207-287-7777.

2. DESCRIPTION OF STUDY AREA The Salmon Falls River runs between Maine and New Hampshire for its entire length (~40 miles) originating from a series of lakes in Acton, Maine, and Wakefield, New Hampshire, and ending at the confluence of the Cocheco and Piscataqua rivers in South Berwick, Maine. The watershed covers approximately 330 square miles and encompasses 9 communities in New Hampshire and 10 communities in Maine (Figure 1, page 2). The 5.5 mile segment of the river that is the subject of the phased TMDL begins in Somersworth, New Hampshire, at river mile 3.3 and ends below the Hamilton House in South Berwick, Maine, at river mile -1.2. This lower part of the study area is tidally influenced. There are four dams in the study area: South Berwick (river mile 0.0), Rollinsford (river mile 1.1), Lower Great Falls (river mile 3.4), and Somersworth (river mile 4.9). Wastewater treatment plant discharges from Berwick and Somersworth flow into the Rollinsford impoundment, while the effluent discharged from Rollinsford and South Berwick flow into the South Berwick impoundment and just below the head of tide, respectively.

3. MONITORING PROGRAM The 2012 sampling was conducted at 7 locations during three sampling events: July 10, July 18, and July 26 (Figure 2). All samples were collected before 8 am, so that sampling occurred when dissolved oxygen (DO) was likely to be the lowest. All sites were accessed by canoe. All sites were monitored for total phosphorus (TP) and ortho-phosphate (ortho-P) using 2 meter integrated core samples. Sites SF16, SF11, SF7, and SF4 were also sampled for chlorophyll-a (Chl-a). Nitrogen compound samples included ammonia, nitrite-nitrate and Total Kjeldahl Nitrogen (TKN) and were collected for SF16, SF5.1, SF5, and SF4. All sites were monitored for pH, dissolved oxygen, and temperature. DO and temperature profiles were measured at 1 meter intervals for all sites, except SF5.1 and SF5 where depths generally only allow a surface measurement. Secchi disk transparency (SDT) was measured on a consistent basis at SF16, SF15, SF11, SF7 and SF4 (see Table 1 for a summary of parameters and sites).

Field data sheets were used to document sample date, personnel, weather conditions, sample collection times, DO, temperature, salinity, meter calibration results, and meter cross check results (Appendix B). All water samples were placed in coolers on ice and delivered for analysis to the Maine Health and Environmental Testing Laboratory (HETL) in Augusta on the day they were collected (Appendix D). HETL chain of custody forms were used to document personnel, sample site, sample collection and delivery times, and other relevant information (Appendix C).

4. WATER QUALITY MONITORING RESULTS The complete Salmon Falls River water quality monitoring results for the 2012 sampling season are presented in Appendix A. Summaries for each site are provided below, along with comparisons to the ME DEP’s recommended water quality standards which include criteria for both Maine and New Hampshire (Table 2). The water quality goals for the Salmon Falls River require compliance with the more stringent standard of the two states and result in a single standard or goal that meets the objectives for both states. Barry Mower of Maine DEP provides the following summary of criteria applying to the Salmon Falls River: Higher levels of Chl-a resulting from excessive TP often result in excessive algal blooms and lower daily minimum dissolved oxygen in the early morning hours, both of which constitute non-attainment of water quality standards. Neither Maine nor New Hampshire have adopted numerical ambient water quality criteria for TP or Chl-a, but both have narrative language and draft or interim criteria that allow for requiring phosphorus controls on point and non-point source inputs in eutrophic waters. While the Maine DEP recommended a target range of 10 to 20 µg/L for Chl-a in the freshwater portion of the Salmon Falls River in the 1999 TMDL, recent data have led to draft criteria with a maximum of 10 µg/L and a spatial mean of 8 µg/L for each impoundment as thresholds not to be exceeded in freshwater impoundments in order to prevent nuisance blooms of blue-green algae

2012 Salmon Falls River TMDL Monitoring Report January 2013

that violate the narrative water quality criteria. Maine DEP has used a TP value of 35 µg/L as a best professional judgment ambient water quality threshold ( BPJ AWQT) for Class C waters for years. Draft TP ambient water quality criteria of 33 µg/L, which would be applied only in conjunction with water quality response variables such as Chl-a, will be proposed for adoption for Class C rivers and streams by rule in 2012. New Hampshire’s 2010 Consolidated Assessment and Listing Methodology for EPA’s 305b report lists interim Chl-a criteria for freshwaters (15 µg/L) and estuaries (20 µg/L). (B. Mower, personal communication, 1/19/2012). Chlorophyll-a exceeded 10 µg/L on 7/26/2012 at SF11 (18 µg/L) and SF7 (16 µg/L). All other Chl-a results were below 10 µg/L. NH DES has published recommended nutrient guidelines for Great Bay (2009). Those recommendations indicate a limit for total nitrogen (TN) concentration of 0.45 mg/L for aquatic life support by protecting DO. More stringent concentrations are listed for various water column depths to protect eelgrass.

Calculated TN (sum of TKN and NO2-NO3) showed 9 of 13 samples exceeding or equal to 0.45 mg/L this summer, with occurrence at least once at every site monitored for this parameter.

Significance of Water Quality Monitoring Parameters Dissolved Oxygen (DO): is the concentration of oxygen that is dissolved in the water. DO is critical to the healthy metabolism of many aquatic organisms. Total Phosphorus (TP): major nutrient naturally present in small amounts in rivers and streams that limits plant growth. Generally, as phosphorus increases, algae and aquatic plants also increase. When algae and plants die, bacteria decompose them and use up oxygen. If DO levels drop too low, fish kills can occur. Low DO in bottom waters can also free phosphorus trapped in the sediments, further increasing the available phosphorus. TP refers to organic and inorganic phosphorus.

Orthophosphate (PO4): sometimes referred to as “reactive phosphorus,” this inorganic compound is the most stable kind of phosphorus and the form used by plants; it is produced by both natural and human processes. Chlorophyll-a : a measurement of the green pigment found in all plants including microscopic plants such as algae. It is used as an estimate of algal biomass; the higher the Chl-a number, the higher the amount of algae in a river or stream.

Ammonia (NH3): a form of inorganic nitrogen that promotes aquatic plant growth and is toxic to fish in excessive amounts. Excess ammonia can also promote algal blooms, particularly in marine waters.

Nitrite-Nitrate Nitrogen (NO2-NO3): another form of inorganic nitrogen that promotes the growth of aquatic plants and algae and can be toxic to fish in excessive amounts. Total Kjeldahl Nitrogen (TKN): the sum of ammonia and organic nitrogen.

Total Nitrogen (TN): the sum of inorganic and organic nitrogen, obtained by TKN + (NO2 + NO3).

Summarized water quality monitoring results for all sites are available in Appendix A. Graphs of DO profiles, water quality parameters, precipitation, and flow rates are in Appendix E. Note that 1 ppm = 1 mg/L, and 1 µg/L = 1 ppb.

Site SF16 SF16 is the furthest upstream sampling location in the study area, and is immediately upstream of the Lower Great Falls Dam. The site was accessed from the New Hampshire side of the river adjacent to a small apartment complex on Rita St. in Somersworth (Figure 3). Water depth is over six meters at this site, and DO concentrations showed consistent stratification, with levels about 8 mg/L at the surface, and near 0.2 mg/L near the bottom. Thermal stratification was pronounced on each sampling date. On 7/26/2012, DO was below 1 mg/L for all depths 4 meters and deeper. TP concentrations ranged from 14 to 17 µg/L, and Ortho-P results ranged between 1 and 2 µg/L. Chl-a concentrations ranged from 3.5 to 8.2 µg/L. TN ranged from 0.43 to 0.50 mg/L, exceeding 0.45 mg/L once on July 26. Secchi disk transparency at SF16 averaged 2.82 meters.

Figure 3: Map and photo of site SF16 in Somersworth, NH.

Site SF15 This site is located just upstream of the Somersworth WPCF, just downstream from the bridge at New Dam Rd / Buffamville Rd (Figure 4). Temperature and dissolved oxygen profiles were generally not stratified, as expected given the shallow depth of about 2 - 2.5 meters. DO readings were 7.0 mg/L or above at the surface and greater than 5 mg/L at all times and depths. TP ranged from 15 to 63 µg/L, and ortho-P ranged from 2 to 35 µg/L, an increase from 2011 results between 1 and 12 µg/L. Secchi disk transparency readings at SF15 regularly hit bottom, with an average depth of 2.32 meters.

Site SF11

This site is located immediately upstream of the Rollinsford Dam (Figure 5). Average depth here is approximately 10 feet (3 meters). The DO profile showed significant stratification during all sampling events. DO stratification became increasingly distinct through the summer, going from 7.3 to 4.8 mg/L, 7.9 to 2.5 mg/L, and finally 10.5 to 0.3 mg/L from surface to three meter depth on July 10, July 18, and July 26, respectively. TP concentrations ranged from 25 to 68 µg/L. Ortho-P results ranged from 2 to 9 µg/L, and Chl-a results were between 3.6 and 18 µg/L. Both ortho-P and chl-a were higher than 2011. Secchi disk transparency at SF11 averaged 2.07 meters.

Site SF7

Site SF7 is located a short distance downstream of the South Berwick Dam, at the end of a wide, slow- moving section of the river (Figure 6). Average depth in 2012 was about 15 feet (4.6 meters). DO and

2012 Salmon Falls River TMDL Monitoring Report January 2013 temperature profiles showed signs of stratification during all sampling events. Dissolved oxygen levels at 3 meter depth were in the range of 4.5 to 5.5 mg/L on all dates. TP ranged from 25 to 30 µg/L, ortho- P was 2 µg/L on all three sampling events, and Chl-a ranged from 5.9 to 16 µg/L. Average secchi disk transparency at SF7 was 2.03 meters.

Figure 6: Map and photo of site SF7 in Rollinsford, NH.

Site SF5.1

SF5.1 is slightly upstream of the Great Works River confluence (Figure 7). Generally, the current is fast and the depth shallow at this riffle, which means that stratification is absent and DO levels can only be measured at the surface or up to 1 meter below. On July 10, deeper conditions allowed for a DO profile to 3 meters depth. Very low flow on July 18 resulted in a surface DO reading only. The minimum DO reading at any depth at SF5.1 was 6.2 mg/L on July 10. TP was moderate to high, with results ranging from 26 to 47 µg/L. Ortho-P results ranged from 3 to 12 µg/L. SF5.1 exceeded the TN limit of 0.45 mg/L on 2 of 3 sampling events.

Figure 7: Map and photo of site SF5.1 in Rollinsford, NH.

2012 Salmon Falls River TMDL Monitoring Report January 2013

Site SF5

This site is located in the Great Works River just upstream of the Salmon Falls River confluence (Figure 8). Water flow is generally minimal at this site due to the Leigh's Mill Dam, and depth varies by tidal cycles. Due to very low flow on 7/18/2012, only a surface readings could be taken. Surface DO was especially low on 7/18/2012 at 3.5 mg/L, and above 5 mg/L at all other times and depths. TP was moderate to high, with readings from 31 to 44 µg/L, and ortho-P ranged from 4 to 14 µg/L. TN was high on 7/10/2012 at 0.52 mg/L and 7/18/2012 at 0.58 mg/L.

SF4

Site SF4 is located just downstream of the Hamilton Brook tributary (Figure 9). Because this segment of the river is tidally influenced, the ME DEP recommended different DO criteria, specifically a daily threshold minimum of 85% saturation. Little stratification occurred on all sampling events. The percent saturation fell below the recommended level on July 10 and July 26 at the water surface. The lowest reading occurred on July 10 at 82% saturation at the surface, and 54% saturation at meter 6. TP ranged from 38 to 57 µg/L, and ortho-P ranged from 6 to 23 µg/L. Chl-a ranged from 8 to 14 µg/L. This is a decrease from 2011 results which ranged from 16 to 51 µg/L. TN was exceeded on 2 of 3 sampling events, ranging from 0.4 to 0.7 mg/L. Average Secchi disk readings at SF4 were 1.70 meters.

5. Compliance with Phased TMDL for the Salmon Falls River Watershed Due to inherent uncertainties in the water quality models used by the ME DEP for the Salmon Falls River TMDL, a phased approach was developed which requires ambient summertime monitoring to assure compliance with Maine’s and New Hampshire’s water quality standards. The TMDL recommends water quality monitoring for a five year period to determine the need for possible further reductions in pollutant loads if water quality standards are not met. The results from the 2012 monitoring season indicate that there are occasional instances at most sites where one or more water quality parameters do not meet the TMDL recommendations. Discussion of future monitoring efforts are ongoing this winter among the regulators: EPA, Maine DEP, and NH DES. Please refer to Appendix A for tables of full water quality monitoring results, Appendix C for raw data results from HETL, and Appendix D for data charts.
