BEAVER DAM, WIS. & PITTSBURGH--(BUSINESS WIRE)--
Evoqua today congratulated the City of Berea, Ohio on receiving regulatory approval from the Environmental Protection Agency (EPA) for implementation of an ETS- UV™ system and being granted disinfection credits that ensure water is safe and healthy for customers.
The City of Berea public water system treats surface water drawn from the East Branch of the Rocky River and sometimes drawn from Coe Lake and Baldwin Creek as needed. As open water sources, they are vulnerable to run off and other forms of contamination. The City installed the ultraviolet (UV) disinfection in response to sampling in 2008, which detected cryptosporidium in the water source.
Conventional treatment of drinking water requires the addition of chemicals to achieve disinfection. Microorganisms such as Cryptosporidium and Giardia have grown a tolerance, requiring higher doses or contact times, which could lead to higher disinfection by-product levels. UV disinfection is an environmentally friendly complement to chemicals for a multi-barrier disinfection approach.
The EPA has adopted Drinking Water protections that require specific parameters for all public systems that use surface water sources. Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) is to protect public health from illness due to Cryptosporidium and other microbial pathogens in drinking water and to address disinfection by-products risk. Credits are achieved when utilities monitor for the presence of Cryptosporidium with a screening procedure control processes.
“It is important that we maintain the highest quality water from our facility, and the ETS-UV system will supplement our conventional disinfection process,” said Sandra Vozar, P.E. Utility Engineer for the City of Berea. She added, “Our facility is a state-of-the-art water treatment facility, and we are proud to disinfect water using UV light to receive disinfection credits for deactivating Cryptosporidium.”
