The City of Paramount began testing its water supply for hexavalent chromium on a monthly basis starting in December of 2016. Since then, there have been 14 consecutive rounds of testing, a schedule that far exceeds most federal and state standards, which generally require such testing only once every three years.
The results for December 2017 indicated a level of 0.118 micrograms per liter (ug/l). The samples taken on January 8, 2018 show a level of 0.30 ug/l.*
“We’ve always known that our water is safe,” said Peggy Lemons, Mayor of Paramount. “Now, a year of constant testing adds further and dramatic confirmation of that fact. Still, just in case there are concerns in the community related to hex chrome in the water, we are committed to continuing our monitoring into the foreseeable future.”
The results for January 2018 and the past year can be viewed on the Hexavalent Chromium Test Results page.
*In 2017, the State Maximum Contaminant Level (MCL) of 10 PPB for hexavalent chromium in water supplies was challenged in court by the California Manufacturers and Technology Association and the Solano County Taxpayers Association. As a result of findings that the State failed to consider economic factors when implementing the MCL, the 10 PPB MCL has been eliminated. The State will continue to enforce a MCL for Total Chromium of 50 PPB; “Total Chromium” refers to chromium in all its forms, including hexavalent chromium as well as other non-harmful chromium. In the 2016 Consumer Confidence Report, the City of Paramount reported 0.12 PPB in Total Chromium in the water supply.
