A report released earlier today raised questions about the levels of Chromium-6 in our drinking water. We want to assure all of our customers that your safety continues to be our top priority. Cleveland Water meets and exceeds all State and Federal drinking water standards as established by the Safe Drinking Water Act and the Ohio Environmental Protection Agency (Ohio EPA), including regulations related to Chromium.
Chromium is a naturally occurring element that can also be caused by man-made sources, and is commonly found in our environment, including our waterways. The US Environmental Protection Agency (US EPA) has an established Maximum Contaminant Level (MCL) for total Chromium (which includes Chromium-6) of 100 parts per billion (PPB). Our most recent testing indicates Cleveland Water’s total Chromium level is 10 PPB. We also recently completed Unregulated Contaminant Monitoring Rule (UCMR 3) testing which indicated our Chromium-6 levels were 0.1 PPB.
Since 2013, we have tested at all four of our water treatment plants and in our distribution system (the water mains that deliver water to you) as required by the USEPA. These results are cited in the recently released report and, when interpreted correctly, show Cleveland Water’s levels are well below the State and Federal MCLs for total Chromium. Additionally, our Chromium-6 results are well below the California MCL of 10 PPB.
Again, the safety of our customers is our top priority. As such, we continuously monitor and test our raw and finished water to ensure we deliver safe, quality water that meets and exceeds all State and Federal drinking water standards.
