Dear GRA Members:
On May 8, 2017, The California State Superior Court issued an order vacating the California State Water Board’s current 10 ppb Hexavalent Chromium Maximum Contaminant Level (MCL). In the Ruling, the court also ordered the State Water Board to establish a new Hexavalent Chromium MCL as close as feasible to the current 0.02 ppb Public Health Goal (PHG) but also includes consideration of the economic feasibility of compliance with the new MCL, particularly for small water systems.
Once a formal judgment is finalized between the Petitioner (California Manufacturers & Technology Association) and the State Water Resources Control Board, the State will proceed with re-establishing an MCL for Hexavalent Chromium.
GRA will continue to be engaged at the State level to review and provide comment on the wise protection and preservation of California’s precious groundwater resources, and we encourage you to do the same. Thank you for being a GRA member.
Chris Petersen, P.G., C.H.G
