WASHINGTON – The US Environmental Protection Agency (EPA) has released the final guidance manual for using ultraviolet (UV) disinfection technology for bringing public water supplies into compliance with the Safe Drinking Water Act, the American Water Works Association's WaterWeek reported recently.
The 436-page manual, which can be downloaded from the EPA Web site, is designed for surface water systems required to install treatment under the Long-Term 2 Enhanced Surface Water Treatment Rule, the report noted.
The manual provides background on fundamentals of UV light, microbial response to UV light, and UV reactors, according to the article.
The document also offers guidance on selection, design, installation, testing, startup, operation, maintenance, monitoring, recording and reporting of UV disinfection to comply with treatment requirements under the LT2 rule, the story said.
