The Stage 2 Disinfection Byproducts Rule (DBPR) was promulgated in January 2006 and applies to all community water systems and non-transient non-community water systems that add a primary or residual disinfectant other than ultraviolet light (UV) or deliver water that has been treated with a primary or residual disinfectant other than UV. FACT SHEET . Stage 2 Disinfectants and Disinfection Byproduct Rule • DBPs are chemical compounds that may form in drinking water when chlorine or other disinfectants react with naturally occurring organic matter in the water. Disinfection by-products (DBPs), also called trihalomethanes, are formed when chlorine and bromine interact with natural organic materials in water, such as in chlorinated drinking water and chlorine-treated swimming pools. DBPs can be found in the air during activities such as showering, bathing, dishwashing, and swimming.

available disinfection reaction time, and type of disinfectant that is used. This fact sheet describes the common disinfection by-products that are monitored in Newfoundland and Labrador. The two most common groups of DPs are trihalomethanes (THMs) and haloacetic acids (HAAs). Fact Sheet: Stage 2 Disinfectants and D isinfection Byproducts Rule In the past 30 years, the Safe Drinking Water Act (SDWA) has been highly effective in protecting public health and has also evolved to respond to new and emerging threats to safe drinking water. Disinfection of drinking water is one of the major public health advances in the Disinfection Byproducts. Although chlorine has been a literal lifesaver with regard to drinking water, it also has the potential to form byproducts that can cause harmful health effects. Chlorine can react with organic materials in water to form disinfection byproducts (DBPs).

DRINKING WATER FACT SHEET #10 What are DBPs and Why is there Concern About their Presence in Drinking Water? Disinfection byproducts (DBPs) form when chlorine or other disinfectants react with organic material (from the decomposition of leaves and other vegetation) naturally found in drinking water sources. The use of chlorine to LT1ESWTR Fact Sheet Page 3 of 4 The LT1ESW TR is part of the larger Microbial and Disinfection Byproducts cluster of rules that include the IESWTR and the DBPR. Implementing the provisions contained in the LT1ESWTR will provide additional protections against the microorganism Cryptos pori dium or Giardia to persons served by small surface water ... The rule targets additional Cryptosporidium treatment requirements for higher risk systems and includes provisions to reduce risks from uncovered finished water storage facilities and to ensure that the systems maintain microbial protection as they take steps to reduce the formation of disinfection byproducts. The Stage 2 Disinfection Byproducts Rule (Stage 2DBPR) which complements Stage1 DBPR focuses on monitoring and reducing concentration of total trihalomethanes (TTHMs) and haloacetic acids (HAA5) through out the distribution system. Disinfectants commonly used in drinking water treatment

DISINFECTION BY-PRODUCTS OVERVIEW Disinfection by-products (DBPs) are formed when natural organic matter reacts with chlorine or other disinfectants. Although hundreds of DBPs FACT SHEET have been reported to occur in drinking water, only 11 are currently regulated because of public health concerns: four trihalomethanes (THMs),
Trihalomethanes: Health Information Summary Trihalomethanes (THMs) are a group of organic chemicals that often occur in drinking water as a result of chlorine treatment for disinfectant purposes and, therefore, are also known as "disinfection byproducts" or DBPs.
