An analysis estimates some of the benefits that could result from reducing exposure to lead in community drinking water supplies. There are two primary categories of benefits evaluated: The public health benefits of reduced lead exposure and reduced materials damages relating to the phenomenon of lead's presence in drinking water. In addition, because the calculation of health benefits depends on the extent of human exposure, another chapter presents the available data on the occurrence of lead in public water supplies, and estimates of the population exposed to drinking water exceeding the proposed standard pf 20 ppb. In assessing the benefits of the proposed reduced lead standard, the analysis assumes that EPA will act to reduce lead levels in drinking water, as well as to maintain the current high quality of water leaving the treatment plant. It also relies upon assumptions about drinking water use and consumption patterns.
