The National Interim Primary Drinking Water Regulations require public notification of maximum contaminant level violations. Data on the cost and effectiveness of the mandated public notification were analyzed for 164 water systems in 14 states. Forty-three percent of the water systems indicated that they did not design their notification to elicit public support for improvements in treatment capability. For those systems that did, 61 percent indicated that it was ineffective in terms of consumer support, 23 percent said it was somewhat effective, and 16 percent said it was very effective. Methods of notification are covered. Includes 2 references, tables.
