Safe Drinking Water Supply for Small & Rural Communities in NL with a Case Study of Pouch Cove
Chlorine is the most common disinfectant used in the province of Newfoundland and Labrador.However, in the presence of natural organic matter (NOM) in drinking-water sources,disinfection by-products (DBPs) are formed when chlorine is used to treat drinking water. The two largest groups of DBPs, trih...
