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.
Disinfection Byproducts Analysis | Thermo Fisher Scientific - US
Disinfection byproducts (DBPs) are produced when disinfectants, such as chlorine, chloramines, chlorine dioxide, and ozone, react with inorganic or organic matter. Common DBPs produced in drinking water include chlorate, chlorite, bromate, trihalomethanes (THMs), and haloacetic acids. Receive updates Join community
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

- 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 is the stage 1 disinfectants and disinfection byproducts rule (DBPR)?
- 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 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.
- Which of the following is an inorganic DBP?
- 2.3. Inorganic Disinfection Byproducts Inorganic DBPs include bromate, chlorite, and chlorate. Bromate is a byproduct of the ozonation process. If the water resource contains bromide ions, the use of ozone as a disinfectant will produce bromate through complex reactions (Aljundi, 2011).
- How to control the production of disinfection byproducts?
- There are several solutions to control the production of disinfection byproducts. Reducing the concentration of precursors is an effective way to control the production of DBPs. The main organic precursors are NOM, algal organic matter, and wastewater effluent organic matter.
- What is the best solution for DBP control?
- Another solution for DBP control is post-treatment, once these byproducts are formed. Activated carbon is effective against THMs and HAAs, and biologically activated carbon can reduce the concentration of biodegradable DBPs. Air stripping is an inexpensive method for the removal of volatile substances.
