Document Description
The Coachella Valley Water District (CVWD) proposes to construct six perched aquifer groundwater monitoring wells within the Coachella Valley’s Indio Sub-basin at various previously developed well site locations. The proposed monitoring wells will be used to monitor groundwater in the perched and shallow aquifers to address gaps and provide improved overall understanding of water quality. The locations of the proposed monitoring well sites are:
1. Gap Well 17 – APN 696-180-067 (City of Indio well site; Ave. 44, Indio)
2. Gap Well 18 – APN 757-250-021 (CVWD Well Site 6807, Ave. 60, Coachella)
3. Gap Well 19 – APN 759-020-029 (CVWD Well Site 6805, Airport Ave., La Quinta)
4. Gap Well 20 – APN 737-200-023 (CVWD parcel at Ave. 83 Drain, Oasis)
5. Gap Well 21 – APN 751-340-018 (CVWD parcel at Ave. 74 and Polk St., Oasis)
6. Gap Well 22 – APN 729-120-020 (CVWD Booster/Reservoir Site 7990, Mecca)
Construction is anticipated for the duration of one week at each site, and will be contained within each site. The wells will be installed using hollow-stem auger, sonic drilling, direct circulation, or mud rotary methods. Initially, the drilling process will require setting a conductor casing and drilling a 4-inch bore hole to a varying depth of 50- to 350-feet for each well. Samples of the drill cuttings will be obtained and logged at 10-foot intervals. Upon completion of drilling, geophysical logging of the test bores will be performed. The wells will be designed based on the information obtained from each borehole. Monitoring will occur at each site as needed and conducted by CVWD staff.
The project site is not located within or adjacent to a conservation area associated with the Coachella Valley Multiple Species Habitat Conservation Plan. The project is not subject to the Coachella Valley Association of Governments Local Development Mitigation Fee because the project location is on existing developed parcels
