DBPRs: What Does it Mean to You? | US EPA
EPA provides guidance documents to help states and public water systems (PWSs) implement the Stage 1 and Stage 2 Disinfectants and Disinfection Byproducts (DBP) Rules. The materials below can assist in complying with requirements of these Rules including updates to reflect the Stage 2 DBP Rule.
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 (DBPs) in Water: What You Need to
Different disinfection byproducts have their own harmful health effects. The most common disinfection byproducts, and their health effects, are: Bromate: vomiting, nausea, diarrhea, abdominal pain, hearing loss, kidney effects, nervous system effects. Chlorate: potential carcinogen, limits the blood’s ability to absorb oxygen, leading to
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.

- What is a disinfection byproduct (DBP)?
- Part of the book series: The Handbook of Environmental Chemistry ( (HEC,volume 135)) Disinfection byproducts (DBPs), formed as secondary contaminants during water disinfection processes, are frequently detected in domestic settings such as drinking water and swimming pools, posing considerable health risks to humans.
- Can chemical disinfection cause DBPs in drinking water?
- However, chemical disinfection can also generate disinfection byproducts (DBPs) as a side effect. To mitigate their risks, many countries and organizations have enacted regulations or guidelines to control DBPs in drinking 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.
- 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.
- What is a DBP in drinking water?
- DBPs are present in most drinking water supplies that have been subject to chlorination, chloramination, ozonation, or treatment with chlorine dioxide.
- Is it possible to remove all DBP precursors during drinking water treatment?
- Overall, it is not only impossible but also economically infeasible remove all DBP precursors during drinking water treatment processes. Additionally, the NOM, AOM, micro-pollutants, halogen ions usually undergo partially removal and transformations.
