Utilities have installed and modified treatment practices to control the formation of regulated DBPs (e.g. THMs). In order to balance the control of regulated DBPs with that of emerging DBPs of health concern, utilities will need to optimize a series of various unit processes to minimize the formation of a wide range of DBPs. Drinking Water Chlorination: A Review of Disinfection Practices and Issues During the treatment process, chlorine is added to drinking water as is the top priority, water systems must also control disinfection products (DBPs), chemical In such cases, it is the monitoring of the sudden drop in the chlorine residual that Case Studies of Modified Disinfection Practices for Trihalomethane Control Completed Provides guidance on disinfection practices for water system designers and operators, based on a review of experiences and practices of systems that have changed treatment processes to comply Table 4.2 Illustrative examples of chlorine decomposition in hypochlorite solution @ 20 C Sources and control of faecal contamination from source to tap. 5 managing the production of drinking water for Water Service Authorities or private disinfection practices will require treated water to achieve certain standards in ptimized corrosion control treatment (OCCT) is a specific requirement of the Lead and Copper Rule (LCR). Methods for achieving OCCT continue to evolve over time. The authors.collected information, reviewed literature, discussed current practices with state regulators, and interviewed corrosion con - In 2003, WRF published Case Studies of Modified Treatment Practices for Disinfection product Control (369), which features lessons learned from 10 diverse drink- ing water utilities that have implemented such treatment modifications. This search uncovered 10 case-control studies and two cohort studies that investigated the relationship between some measure of exposure to DBPs and cancer. These studies were then scored, using a blind ranking system, on the basis of selection of subjects, confounding variables, exposure assessment, and statistical analysis.
