Disinfection By-Product Risk Assessment: DBPs of Concern

Price: £13  

The disinfection by-product (DBP) rule requires water companies to keep DBPs in drinking water as low as possible without compromising the effectiveness of disinfection. In the UK, emphasis has been on the regulated DBPs, mainly the trihalomethanes (THMs), but other DBPs must not be present at concentrations that constitute a potential danger to human health. 

The large number of known DBPs makes measurement impractical, if not impossible. Accordingly, a pragmatic risk-based approach to identify potential DBPs has been developed, based on knowledge of factors which lead to their formation and mitigation. DBPs have been categorised according to their chemical structures and the potential risks for these categories, based on toxicity, likely occurrence and concentration.

This approach has been encapsulated in a spreadsheet-based risk assessment tool that enables the potential formation of DBPs at treatment works to be quickly assessed, and the works to be ranked according to the risk.
