An evaluation was performed of the Promulgated Interim Primary Drinking Water Regulations prescribed by the Environmental Protection Agency. The results of this study indicate that the annual costs for water monitoring for community systems will be between $12 million and $25 million, while the costs for water monitoring for non-community systems will be between $4.5 million and $9.5 million. Between $1.1 billion and $1.8 billion will be required to build additional treatment facilities for removing contaminants from the nation's drinking waters. It will cost $263 million per year for operation and maintenance of these required facilities. The annual per capita costs for those systems which will require treatment range from $240 for a system serving 25 people and treating for heavy metal removal to under $0.25 per year for systems serving over 100,000 people requiring disinfection. A constraint analysis examined the broad areas of chemicals and supplies, manpower, laboratories, and engineering and construction services.
