Guidance Manual For Compliance With The Filtration And Disinfection Requirements For Public Water Systems Using Surface Water Sources

Guidance Manual for Compliance with the Filtration and Disinfection Requirements for Public Water Systems Using Surface Water Sources

LT1ESWTR disinfection profiling and benchmarking technical guidance manual.

This guidance manual is intended to help public water systems (PWSs) comply with the disinfection profiling and benchmarking requirements of the Long Term 1 Enhanced Surface Water Treatment Rule (LT1ESWTR). The requirements of the LT1ESWTR apply to PWSs that: Serve fewer than 10,000 people; and, are classified as either surface water or ground water under the direct influence of surface water (GWUDI). This manual explains disinfection profiling and benchmarking, discusses when and why they are necessary, and provides guidance as to how to compile a disinfection profile and how to calculate the benchmark. This guidance manual also discusses how systems and States may use these data to make decisions about disinfection practices.

Public water systems deliver high-quality water to the public. They also present a vast array of problems, from pollution monitoring and control to the fundamentals of hydraulics and pipe fitting.
