Disinfection Byproducts

Disinfection byproducts or DBPs, are chemicals that are formed when organic carbon reacts with chlorine, a chemical used to disinfect water against pathogenic organisms.

Disinfection byproducts or DBPs, are chemicals that are formed when organic carbon reacts with chlorine, a chemical used to disinfect water against pathogenic organisms. DBPs include the groups of chemicals known as trihalomethanes and haloacetic acids. Health effects from long-term or chronic exposure to high levels of DBPs include an increased risk for cancer and other potential health effects currently under investigation.

All community and nontransient, noncommunity water systems must now monitor for DBPs.
