Disinfection By-products (DBPs) Factsheet | National
Disinfection By-products (DBPs) Factsheet. Disinfection by-products (DBPs) are formed when disinfectants like chlorine 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.

Emerging Disinfection Byproducts Treatment Project #5005 Nitrosamine Precursors in Direct and Indirect Potable Reuse Water Research Investment $49,581 Completion Year 2025 Completed Project Highlights There is growing interest in nitrosamines, including N-nitrosodiethylamine (NDEA), and their precursors.
Optimization to Reduce Disinfection Byproducts (DBPs)
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. U.S. EPA, in partnership with participating State AWOP members and the Association of State Drinking Water Administrators (ASDWA
Stage 1 and Stage 2 Disinfectants and Disinfection Byproducts
The Stage 1 Disinfectants and Disinfection Byproducts Rule (DBPR) reduces drinking water exposure to disinfection byproducts. The Rule applies to community water systems and non-transient non-community systems, including those serving fewer than 10,000 people that add a disinfectant to the drinking water during any part of the treatment process.

Disinfection byproducts (DBP) can form when naturally occurring organic carbon reacts with a chemical disinfectant such as chlorine. US EPA has more information on specific DBP compounds. Vermont Department of Health has more information on health effects of DBP. A Community (C) or Non-Transient Non-Community (NTNC) public drinking water system
- What are disinfection byproducts (DBPs) in wastewater treatment plants?
- Effluents containing disinfection byproducts (DBPs) from wastewater treatment plants (WWTPs) may be discharged to the receiving water bodies or reused for irrigation, landscaping, and environmental supplies as well as a source to replenish groundwater. Thus the formation and risk of the DBPs in disinfected wastewater effluents should be concerned.
- Are harmful disinfection byproducts in water treatment safe?
- Growing concerns over public health and environmental safety have intensified the focus on minimizing harmful disinfection byproducts (DBPs) in water treatment. Traditional methods like chlorination, while effective against pathogens, often lead to the formation of DBPs, which pose significant risks.
- Which disinfection byproducts are more toxic than C-DBPs?
- On the other hand, N-DBPs, which include haloacetonitriles (HANs), halonitromethanes (HNMs), haloacetamides (HAcAms), and nitrosamines (NAs), are generally more toxic than C-DBPs . Nitrogenous disinfection byproducts (N-DBPs) and iodinated disinfection byproducts (I-DBPs) are becoming increasingly concerning in water treatment.
- How does disinfection optimization affect DBP formation?
- Thus, disinfection optimization (disinfectant, dose, and reaction time) plays significant roles in control of DBPs formation as well. FC is the most common disinfectant for water treatment at present, due to its high effectiveness, low cost, and ease of prepare.
- Are DBPs formed during the disinfection of secondary effluent?
- The research evaluates DBP occurrence in full-scale advanced water treatment plants and their formation and speciation during the disinfection of secondary effluent. The research found that DBPs were formed during the disinfection of secondary effluent and not all were rejected well by the membranes.
- Can chlorination reduce DBP formation while ensuring effective disinfection?
- Traditional methods like chlorination, while effective against pathogens, often lead to the formation of DBPs, which pose significant risks. This paper explores alternative strategies to reducing DBP formation while ensuring effective disinfection.
