Document Title
Municipal Groundwater Improvement Project
Document Type
MND - Mitigated Negative Declaration
Present Land Use
Storm water basins and fallow ag land
Document Description
The Project would construct five Managed Aquifer Recharge (MAR) basins and associated irrigation water conveyance in the City and County areas. Irrigation water conveyance would include construction of above ground and/or subterranean pipelines, Modesto Irrigation District canal turnouts, outfall structures, and pump stations to transport irrigation water to the MAR basins. The Project is intended to address non-point source groundwater contamination from arsenic, nitrate, and uranium in the aquifers underlying the City of Modesto water service areas. The Project consists primarily of: (1) modification of City of Modesto water supply well field pumping operations, i.e., wellfield optimization, to reduce contaminant levels in raw pumped groundwater; and (2) construction of MAR basins to increase the volume (i.e., recharge) of uncontaminated water within the aquifer system.
