• Disinfection by-product experiences in Alaskan village drinking water systems and the Caribou-Poker Creek watershed

      Narr, Jasprit (2001-08)
      The purpose of this research was to study the disinfection by-product formation potential (DBPFP) in small drinking water systems in Alaska. As per the US. E.P.A's disinfectants/disinfection by-products (D/DBP) rule, the maximum contaminant limit (MCL) for the two major DBPs namely, total trihalomethanes (TTHMs) is 80 micrograms (ug) per liter (L) and 60 micrograms/liter for the five 5 halloacetic acids (HAA5). It was decided to conduct research on the total trihalomethane formation potential (TTHMFP) and the 5- haloacetic acid formation potential (HAA5PF) of the 17 Alaskan village drinking water systems with reportedly high TTHM and HAA5 values. It was found that specific UV absorbance (SUVA) had excellent correlations with TTHM/DOC and HAA5/DOC. These correlations were used to aid in drinking water source selection in a sub-arctic watershed named the Caribou-Poker Creek Research Watershed (CPCRW).
