The Village of Chagrin Falls fully understands the concern that our customers may have over the recent report raising questions about the levels of chromium-6 in public drinking water systems. Our top priority is to deliver safe drinking water to our customers. Chagrin Falls 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-3 is an essential human dietary element. It is found in many vegetables, fruits, meats, grains, and yeast. Chromium-6 occurs naturally in the environment from the erosion of natural chromium deposits. It can also be produced and used in industrial processes. High concentrations of chromium-6 have been linked to cancer in laboratory animals. Chromium-6 is frequently found in low concentrations in our environment, including source water used for drinking water. 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), (one part per billion is equivalent to one drop in a 14,000 gallon pool). Our most recent testing results (2013) indicates Chagrin Water’s total Chromium level is non-detectable (a concentration below the detection limit of the test). We also recently completed Unregulated Contaminant Monitoring Rule (UCMR 3) testing which indicated our Chromium-6 levels were 0.23 PPB at the village wells and non-detectable in the distribution system (the water mains that deliver water to the customers).
Since 2013, we have tested at our wells and our distribution system as required by the USEPA. Chagrin’s water supply results for Chromium-6 results are well below the stringent California standard of 10 PPB.
Again, the safety of our customers is our highest 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.
