The proposed Project consists of the destruction of the JCSD’s Well 19 and site acquisition, design, drilling, construction, and operation of a new community groundwater well identified as Well 30 (District Project No. C195054). The proposed Well 30 site is an approximately 0.96-acre vacant parcel (APN 156-310-063) located south and east of the approximately 0.11-acre Well 19 site (APN 156-332-021).
Well 30 is proposed to be approximately 20 inches in diameter and drilled to a depth of approximately 850 feet below ground surface. Well 30 would be equipped with a 400 to 600 horse power (hp) electric motor. The wellhead and approximately 200 linear feet of above-ground piping (including valves) would be constructed on top of a concrete pad. Site improvements also include an approximately 340 square foot (SF) electrical building to house the electronics to operate the well; SCADA antenna, standby backup diesel generators installed on a concrete pad in a waterproof enclosure; a Southern California Edison (SCE) meter and transformer, both installed on concrete pads; an approximately 890 SF chemical building, driveway access to the site from Etiwanda Avenue, and approximately 160 linear feet (LF) of water pipeline from the wellhead to JCSD’s existing water pipeline in Philadelphia Avenue.
The Project will also include on-site drainage facilities to convey site runoff into the existing storm drain system. Operation of Well 30 will entail regular maintenance of the equipment and grounds of the well site. It is anticipated that JCSD personnel will visit the Well 30 site on a daily basis, which is the same frequency personnel are currently visiting Well 19.
For security purposes, the Well 30 site will be enclosed with either a chain link fence or a solid wall. Access to the site will be via a locked gate from Philadelphia Avenue.
Construction of Well 30 is estimated to take approximately 17 months and destruction of Well 19 is estimated to take approximately one month; for a total construction/destruction period of approximately 18 months.
Destruction and abandonment of Well 19 would entail the removal of all above-ground buildings and piping on the Well 19 site and deconstruction of Well 19. Destruction of Well 19 would serve the dual purpose of protecting the groundwater supply and eliminating potential physical hazards. The process for destroying a well entails cleaning the well to remove undesirable materials, including obstructions, to filling and sealing the well. All debris, oil from oil-lubricated pumps, and pollutants and contaminants that could interfere with well destruction would be removed and disposed of in accordance with applicable regulations. The Well 19 casing may be perforated or removed in whole or in part prior to filling Well 19 with suitable impervious sealing material. (DWR Part III.)
