Below is the evaluation summary for the 30350 Tracy Blvd. industrial Well (APN 25313011)-well permit <br /> application. <br /> The evaluation, with assumptions as noted, indicates that the proposed Irrigation well is located in an <br /> area of low domestic/residential well density(1 well per section), General Plan designation AG (0.0- <br /> 0.05 Dwelling units per acre) but is not likely to interfere significantly with existing off-site wells, create <br /> unreasonable groundwater level declines/reductions in aquifer storage or to create issues with <br /> infrastructure due to subsidence and it can be approved pending any other issues that you might have <br /> with the application. <br /> Summary: <br /> - The applicant proposes: well depth of 600 feet, a well grout seal of 200 feet with extraction rate <br /> —200 GPM with anticipated pumping schedule 120,000 Gal/day in a 46.09 acre lot. <br /> - Proposed new well is in an area of agriculture (0.0—0.05 Dwelling units per acre) well density ( 4 <br /> wells in section T3S/R5E/16).At least one well is located approximately 200 feet Southwest of the <br /> proposed industrial well <br /> - Based on the extraction rate of 200 GPM, The Theis drawdown chart predicts less than 5 feet of <br /> drawdown if the well is more than 1 foot away from proposed well. <br /> - Online databases suggest any industrial well located within 1,450 feet of the proposed well <br /> location.The well is located to the east of the proposed well. <br /> - Groundwater levels estimated by DWR well data range between 153 (11/14/200) to 193 <br /> (10/31/1986) foot below ground surface over the past fifty years. Water levels fluctuate <br /> approximately10 to 30 feet between seasonal high and low levels. <br /> - The permit application proposes a minimum well casing/grout seal of 200 feet and appears to <br /> target the Modesto-Riverbank aquifer with water-bearing zones anticipated to be under <br /> unconfined to locally confined conditions. <br /> - The annual total extracted volume is estimated to be approximately 45 million gallons, a peak <br /> pumping rate of 536 GPM, and an annualized/seasonal pumping rate of approximately 179 <br /> GPM. <br /> - The aquifer volume below the 46.09-acre parcel contains an estimated 5,151 acre-feet of water <br /> storage.The proposed extraction volume of 138 acre-feet per year is approximately 2.7%of the <br /> estimated aquifer storage beneath the parcel without regard to recharge each season and is <br /> considered sustainable. <br /> - The proposed well is located within the extents of the Corcoran Clay. Depth of the Corcoran clay <br /> is estimated to be between 200 to 250 feet in depth. <br />
