Document Description
The proposed project includes: demolition of an existing well house; construction of a new Upper Aquifer Well and if required, skid-mounted ion-exchange unit (nitrate removal facility); and, installation of a pre-manufactured, approximately 600-square foot, metal building to house the existing and proposed wells and nitrate removal facility. The ion-exchange unit will be used to treat approximately 75 to 100 gallons per minute, or approximately 100 to 150 acre-feet per year (afy), of high nitrate water from the new well. The nitrate removal facility will generate approximately 2,800 gallons of brine waste 3-4 times per week. A new 7,000-gallon High Density Polyethylene tank for brine storage will be located within the yard, and will be emptied 3-4 times per week, and trucks will haul the brine off-site for disposal at an approved facility. The brine storage tank will have a high level alarm that will shut the well down in the event the brine waste reaches the high level, which will prevent overflowing. The project includes a new underground waterline that will connect the proposed well to the existing water main located onsite and a new 90-foot long underground pipeline to connect the proposed nitrate removal facility to the proposed brine storage tank. Existing electric utilities will be connected to the new building, and will not require additional ground disturbance. Installation of the new well will increase production from the upper aquifer by 100-150 afy, thus reducing the pumping from the Lower Aquifer by the same amount. The approximate area of disturbance will be up to 1,200 square feet, within the approximately 0.5-acre work yard. Construction would occur during daytime hours during the dry season.
