- Abstract
- In an attempt to provide more accurate exposure levels to disinfection by-products (DBPs) in drinking water by consumers, the levels of trihalomethanes (THMs), haloacetic acids (HAAs), and total organic halogen (TOX) were measured and correlated between the point of entry (POE) from an ozone-chloramination plant and those measured throughout the distribution system (DS). Samples collected every four hours during five consecutive days showed that temporal variability in the DBP levels at the POE can be expected. However, this variability appeared to be dampened in the distribution system with the average levels of DBPs measured over an extended period very similar at all sample points. A single grab sample collected from a representative DS point would therefore be a good indication of DBP exposure to consumers of that drinking water. This study will demonstrate how a monitoring program was evolved that provides for a reasonable exposure level of DBPs to consumers of drinking water using a minimum number of sampling points and events in a chloraminated distribution system.
