To meet the requirements of Ohio EPA’s lead and copper regulations, Cleveland Water is required to add orthophosphate to our water for corrosion control. We are required to maintain a minimum level of 0.8 mg/L, allowing deviations on only 9 days during a six month period. Unfortunately, during the July to December 2009 monitoring period, there were 11 days when we failed to maintain the required dosage of orthophosphate at the Crown Water Treatment Plant. 

Since 1997, we have consistently added orthophosphate during our treatment process for corrosion control. The recent occurrence is the first time we neglected to maintain the required level, according to Ohio EPA standards. Tests performed since the time of deviation from normal corrosion control show that the reduced dosage has had no impact on the amount of lead and copper in your water. We will continue to perform hundreds of water quality tests every day to control our treatment process and ensure our customers continue to receive the highest quality water.

If you have any questions, please contact Cleveland Water on our special hotline for Crown customers at 216-443-2457 for further information.

Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses). You can do this by posting this notice in a public place or distributing copies by hand or mail.
