As-Needed Hydrogeological Support Client: Eastern Municipal Water District, P.O. Box 8300, Perris, California 92572-8300 Client Reference: John Daverin, Daniel Thomas, 951.928.3777 Key Personnel: Kayvan Ilkhanipour, Ron Schnabel, Stephen Dickey, Patrick Rentz Dudek assisted the District with a test boring at the City of Moreno Valley Corporate Yard located at 25180 Santiago Drive in Moreno Valley, California. The purpose of the borehole was to determine subsurface aquifer lithology, test potential zones of groundwater production by airlifting with dual wall drill tools, measure geophysical logs of the completed borehole, and to collect water quality samples for laboratory analysis. The principle goals of the project were to (1) determine depth to bedrock, (2) estimate potential aquifer yield, and (3) if possible to determine formation water quality prior to construction of water supply well. Santiago Test Boring The borehole was advanced to 803 feet and encountered the weathered upper bedrock contact at 680 feet. Cuttings were collected and described from surface to total borehole depth. Static water table was encountered in the open borehole at 61 feet below ground surface, although previous geotechnical work by CHJ Labs encountered perched water at shallower depths.

Dudek is currently assisted the District with the drilling, construction, isolation zone testing, development, and well testing of Well 205. Dudek provided 24/7 staffing during the well construction and testing phases requested by the District. Dudek will be providing the District with a well completion report at the end of construction. Well 205 Construction Management

Preliminary Well Design and Specifications for District Well 37: Dudek provided preliminary well design and well specifications to the District for Well 37. Dudek worked with the District to prepare well specifications, which were used to obtain bid estimates from state-licensed drilling contractors. Dudek also provided an engineering cost estimate, estimated drilling schedule, and contract bidding assistance to the District.

The well design and well specifications consisted of one new fully developed and tested municipal water well, including; drilling, downhole geophysical logs, isolated aquifer zone testing, caliper logs, installation of well casing and screen tubing, filter pack, annular seals, well development, final pumping tests, flow meter survey, well disinfection, and capping. The work also includes the construction of one new monitoring well and the demolition and removal of a well water treatment building on the new production well site.

Well Abandonment Services for District Monitoring Well No. 2: Dudek provided abandonment services to the District for Monitoring Well No. 2. Dudek worked with the District’s well service contractor, obtained a monitoring well destruction permit, provided on-site well destruction observation, and prepared a final summary well destruction report.

Paradise Valley Hydrogeological and Well Construction Services Client: Glorious Land Company, 5556 N. Diamond Bar Blvd., Suite 212, Diamond Bar, California 91765 Client Reference: Paul Lin, 909.860.3107 Key Personnel: Ron Schnabel Dudek is conducting the Groundwater Study for the Glorious Land Company. The Glorious Land Company owns approximately 8,000 acres of land near Coachella, is in the process of completing a Land Plan for approximately 1,800 acres of their 8,000 acres, and will be submitting an environmental impact report (EIR) for a general plan amendment, zone change, specific plan, vesting tentative map, and possible development agreement for this property. The project’s water supply relies on various agreements and will utilize groundwater storage through an artificial recharge and recovery system (i.e., banking project) developed on site. The water supply will consist of recharged imported Colorado River Water and local groundwater produced within limits partially determined by the Dudek’s study. Dudek conducted the following components for the groundwater study:

 Constructed a production well for water supply, baseline water level Production Well Drilling at measuring, water quality sampling, and aquifer testing; Paradise Valley  Constructed five monitoring wells for water level monitoring, water quality sampling, and aquifer characterization;  Constructed and tested a test recharge basin, including infiltration rate testing utilizing falling-head percolation testing and constant-head percolation rate testing;  Modeled groundwater, including groundwater recharge and banking operational scenarios;  Batch-tested water/soil using Colorado River Water;  Supported EIR preparation; and  Developed a groundwater monitoring plan.

Bagdasarian Farms Well Services Client: Bagdasarian Farms, 65-500 Lincoln Street Client Reference: Mike Bozick, (760) 396-2168 Key Personnel: Stephen Dickey, Patrick Rentz Dudek hydrogeology has completed well service and technical work for Bagdasarian Farms (Bagdasarian) for several years. Bagdasarian owns and operates several farms, vineyards, and groves in the Coachella Valley and Blythe area. Bagdasarian purchased a 900-acre fallow vineyard at Oasis, which was no longer farmed due to poor, deteriorated water quality of the farm’s existing irrigation wells.

Dudek worked with wireline service contractors to conduct spinner tests, temperature logs, and zone specific testing of the deteriorated irrigation wells to better define the source of high total dissolved solids (TDS)/ chloride/boron water quality issues. Dudek also conducted geophysical surveys to provide additional information on the ranch’s aquifer thickness and characteristics not defined by the small footprint of the farm’s well field.

Dudek then worked with a well contractor to conduct careful zone testing of a deep pilot borehole at the most promising irrigation well site. With water chemistry derived from five pilot hole zone samples, it was determined that the deepest zones were impaired by elevated water temperature associated with high TDS, chloride, and boron. The uppermost zones were significantly impaired by very high chloride and TDS levels due to long term irrigation water leach-down from previous farming operations.

On-Call Engineering and Professional Services – Category P: Hydrogeology 5

With the pilot hole zone test results and geophysical logs, an irrigation well was designed and completed with deep annular well seals that restrict the new well’s extraction to a middle zone with favorable water quality for crops. This well has been operating for 3 years, and is presently pumping 1,600 gpm, 24 hours per day in summer months irrigating a grove approximately 9,000 lemon, lime, and mango trees that require low chloride and low boron concentrations.
