Stage 1 and Stage 2 Disinfectants and Disinfection Byproducts
The Stage 1 and Stage 2 Disinfectants and Disinfection Byproducts Rules (DBPRs) are part of the suite of Microbial and Disinfection Byproducts Rules (MDBPs). MDBPs are a series of interrelated regulations that address risks from microbial pathogens and disinfectants/disinfection byproducts.

Optimization to Reduce Disinfection Byproducts (DBPs)
Reducing Disinfection Byproducts through Optimization Webinar Series The Area-Wide Optimization Program (AWOP) has developed tools and approaches that both parent and consecutive drinking water systems can utilize to reduce DBPs in the water treatment plant and the distribution system.

Disinfection vs Disinfection Byproducts (DBPs): A Complex Balancing Act Diarrheal diseases associated with poor water sanitation remain a leading cause of death in the developing world, particularly among children.
Overview of Disinfection By-products and Associated Health
Future research should develop methods to evaluate the effects of the DBP mixture and the interaction with personal characteristics (e.g., genetics, lifestyle), clarify the association between swimming pools and respiratory health, evaluate the occurrence of DBPs in low- and middle-income countries, and evaluate outcomes suggested by animal
- What are global disinfection by-products (DBP) regulations?
- This study provides an overview of global disinfection by-products (DBP) regulations and lists current DBP standards of 166 countries with total trihalomethanes (TTHM), haloacetic acids (HAAs), and chlorine residual being the most widely regulated water quality parameters in the world.
- What are disinfection by-products (DBPs)?
- Disinfection by-products (DBPs) are organic and inorganic compounds resulting from chemical reactions between organic and inorganic substances such as contaminates and chemical treatment disinfection agents, respectively, in water during water disinfection processes.
- What are disinfection byproducts?
- Disinfection byproducts are chemical, organic and inorganic substances that can form during a reaction of a disinfectant with naturally present organic matter in the water. They are formed when disinfectants, such as chlorine, react with naturally present compounds in the water.
- Are disinfection byproducts toxic?
- Disinfection byproducts (DBPs) formed during the disinfection of water have drawn significant public concern owing to their diverse toxicities. In this study, a database of 6310 DBPs reported since 1974 was constructed.
- Are trihalomethanes a disinfection by-product?
- Since trihalomethanes were discovered in 1974, disinfection by-products (DBPs) in drinking water have attracted extensive attention. In 2011, more than 600 known DBPs were compiled; however, newly reported DBPs have not been integrated.
- What percentage of DBPs are verified by chemical standards?
- Only 10% of reported DBPs are verified by chemical standards. Acids are the largest category among all functional groups of reported DBPs. Structures of proposed DBPs were characterized based on adjusted indexes. Since trihalomethanes were discovered in 1974, disinfection by-products (DBPs) in drinking water have attracted extensive attention.
