Abstract: The problems encountered when small systems must meet the provisions of the National Primary Drinking Water Regulations are discussed. Among the potential water quality problems that could be encountered are high concentrations of inorganic substances such as nitrates, naturally occurring fluorides, radioactive substances, asbestos, or arsenic. An additional problem exists in terms of the growing preponderance of synthetic trace chemicals, usually organic in nature, in the industrialized sections of the country. Improper disposal of hazardous wastes also creates the new problem of surface water, as well as groundwater contamination. The use of the WATMAN (WATer MANagement) model for evaluating the economics of both conventional and new technologies is discussed.
