Status Report on Watermaster’s Water Quality Management Activities May 20, 2003
Watermaster’s Activities to Characterize Water Quality through OBMP • Watermaster initiated comprehensive water quality monitoring program: • Samples 200 to 300 wells annually in southern Chino Basin; 205(j) Groundwater Quality Study; Hydraulic Control Monitoring Program • Obtains water quality data for non-ag pumpers from the pumpers, DHS and others • Obtains reports and data from RWQCB, DHS, DTSC, Counties and others
Watermaster’s Activities to Characterize Water Quality through OBMP • Maintains a comprehensive data base • Geologic data from wells • Groundwater level and quality • Migrating from MS Access-based to EQUIS SQL-based system • Has developed a comprehensive geographical information system for characterizing groundwater conditions in the Chino Basin
Watermaster’s 2002/2003 Monitoring Program • General minerals/general physical • Perchlorate • 1,2,3-Trichloropropane • Wells within or near VOC plumes • Following analytes where not previously sampled in 1999/2000: • hexavalent chromium • Si, Sr, Ba • coliforms
Watermaster’s Recommendation for On-Going Monitoring • Conclusion/recommendation of the 205(j) Final Technical Memorandum: • Continued monitoring of water levels and water quality influent to the desalter well fields is critical to optimizing the performance of these treatment facilities. • Water levels should be measured at least annually. • All private wells should be sampled for general mineral and general physical parameters at least once every three years. • Sampled for other contaminants (volatile organic chemicals [VOCs], perchlorate, etc.) at least once every six years.

Watermaster’s Activities to Characterize Water Quality through OBMP • Watermaster initiated comprehensive water quality monitoring program: • Samples 200 to 300 wells annually in southern Chino Basin; 205(j) Groundwater Quality Study; Hydraulic Control Monitoring Program • Obtains water quality data for non-ag pumpers from the pumpers, DHS and others • Routinely obtains reports and data from RWQCB, DHS, DTSC, Counties and others
Watermaster’s Activities to Characterize Water Quality through OBMP • Maintains a comprehensive data base • Geologic data from wells • Groundwater level and quality • Migrating from MS Access-based to EQUIS SQL-based system • Have developed a comprehensive geographical information system for characterizing groundwater conditions in the Chino Basin
Watermaster’s Recommendation for On-Going Monitoring • Conclusion/recommendation : • Watermaster should continue monitor water levels and water quality influent to the desalter well fields. • Water levels should be measured at least semi annually but preferably monthly. • All private wells should be sampled for: • general mineral and general physical parameters at least once every three years • other contaminants (volatile organic chemicals [VOCs], perchlorate, etc.) at least once every six years.
Watermaster’s Recommendation for On-Going Monitoring • Conclusion/recommendation : • Continue Cooperative monitoring programs with producers and other entities • Continue the surface water quality monitoring program in flood control and recharge basins. • Continue surface water monitoring in the Santa Ana River and tributaries as per the Hydraulic Control Monitoring Program
