The primary purpose of the AWWARF study was to develop and assess the applicability of predictive equations for the formation of trihalomethanes (THMs) and haloacetic acids (HAAs) in water distribution systems, and to develop tools for linking these equations with epidemiologic studies.
AWWARF is funded primarily through annual subscription payments from over 1,000 utilities, consulting firms, and manufacturers in North America and abroad.

In searching for an effective chemical treatment program, six different chemicals--sodium hypochlorite, hydrogen peroxide plus iron, potassium permanganate, chlorine dioxide, chloramine, and ammonia--were all tested under the AWWARF grant at two different test locations.
A review of the data involved in the chemical research program, including water quality information, is detailed in the AWWARF report "Controlling Zebra Mussels at Water Treatment Plant Intakes.
Requests for proposals (RFPs) for 30 projects will be available on the AWWARF web site (www.
