February marks the third month of hexavalent chromium testing for the City’s water supply, far exceeding federal- and state- testing requirements. The City of Paramount remains committed to these frequent rounds of testing to assure residents that the area’s water supply remains safe from the carcinogen.
Last month, the test results showed hexavalent chromium to be 0.09 micrograms per liter (ug/l), which is less than the detection limit of 1 part per billion (ppb) for drinking water. The samples taken at the beginning of February indicate a level of 0.21 ug/l; this amount is well below the Maximum Contaminant Level (MCL) of 10 ug/l for the State of California. The monthly testing process is helping establish a baseline value, so fluctuations in the measured amount that remain below the established MCL are expected.
“The City’s water supply remains well-within healthy standards for hexavalent chromium emissions. The frequency of our testing will result in a detailed baseline for hexavalent chromium levels in our water to effective oversight into the future,” said Mayor Daryl Hofemeyer.
The City has adjusted the timing of the hexavalent chromium testing in the water to align with its other routine monthly samples. Therefore, test results will be returned closer to the beginning of the month and will be published to the website earlier in the month. The results for February and previous months can be viewed on the Hexavalent Chromium Test Results page.
