Ancil Hoffman GET “L-A” Update
Design started at same time as GET L-B
but separated to allow public outreach
and siting process in Ancil Hoffman Park
to proceed at a slower pace
Milestone Achieved August 8, 2007:
Ancil Hoffman GET “L-A” Facility
location approved by County Board of
Supervisors

Ancil Hoffman GET “L-A” Update
CWD Participation includes Buried Reservoir and new Irrigation Pump Station for Golf Course
Reuse of Remediated Groundwater offsets surface water and maintains beneficial use of groundwater
Construction Buried Reservoir estimated to start Summer 2008

Strategic Goals
1. Early Detection & Identification of
Contaminants Near Our Water Supply Wells.
2. Expansion of the Bajamont Water Treatment
Plant.
3. Assist Aerojet in Locating, Permitting
Remediation Facilities.
4. Using Treated, Extracted Groundwater at
Ancil Hoffman Park.

Strategic Goals
5. Increased Conservation Efforts to Reduce Overall Demand.
6. Identify Potential Funding Sources for Projects.
7. Work Regionally to Enact Legislation to Increase Funding to Expedite Remediation Efforts.
8. Legal Representation.
