6. Regional Geology

7. CWD Service Area Wells and NDMA Plume

10. Water Supply Reliability • Expanding Surface Water Treatment Plant from 16 MGD to 21 MGD • New Membrane Treatment Modules • Additional Treated Water Pumping Capacity • Additional Chemical Treatment and Air Handling • Expected Completion Plant Expansion May 2008

11. Water Supply Reliability • Water Rights Permit Extension Filed with Department of Water Resources • CEQA Process Underway to Support Permit Extension Request • Expected Completion Late 2008

12. Water Supply Reliability • Participating in Regional Activities • Briefings with Congressional Representative • Briefings with State Government Representatives • Briefings with County and Local Representatives • Sacramento Groundwater Authority Contamination Task Force • ACWA Cap to Cap Outreach

13. GET “L-A” and “L-B” Remediation • GET “L-B” – Bajamont Site Operational at 600 gpm and Discharging to the American River • GET “L-A” – Design Underway with Irrigation Reuse (1MGD) and Wet Weather Discharge to American River

15. GET Treatment Process Summary

16. Bajamont GET “L-B” Update • Bajamont GET “L-B” Facility Construction complete – Startup Extraction Well September 7, 2007 • Construction met date set by EPA • “Operational and Functional” Certification by EPA Pending Completion GET “L-A”

17. Bajamont GET “L-B” Facility • Sample Heading • First level bullet • Second level bullet • Third level bullet

18. Bajamont GET “L-B” Facility • Sample Heading • First level bullet • Second level bullet • Third level bullet

19. Bajamont GET “L-B” Facility • Sample Heading • First level bullet • Second level bullet • Third level bullet

20. GET “L-B” Completed

21. 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

22. 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

23. 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.

24. 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.
