Impact/Purpose:

In this paper, we review the community-intervention studies that have assessed changes in waterborne gastroenteritis risks among immunocompetent populations in industrialized counties

Description:

The nature and magnitude of endemic waterborne disease are not well characterized in the

United States. Epidemiologic studies of various designs can provide an estimate of the

waterborne attributable risk along with other types of information. Community drinking water

systems frequently improve their operations and may change drinking water treatment and their

major source of water. In the United States, many of these treatment changes are the result of

regulations promulgated under the Safe Drinking Water Act. A community-intervention study

design takes advantage of these 'natural' experiments to assess changes in health risks. In this

paper, we review the community-intervention studies that have assessed changes in waterborne

gastroenteritis risks among immunocompetent populations in industrialized countries. Published

results are available from two studies in Australia, one study in the United Kingdom, and one

study in the United States. Preliminary results from two other US studies are also available.

Although the current information is limited, the risks reported in these community-intervention

studies can help inform the national estimate of endemic waterborne gastroenteritis. Information

is provided about endemic waterborne risks for unfiltered surface water sources and a

groundwater under the influence of surface water. Community-intervention studies with

recommended study modifications should be conducted to better estimate the benefits

associated with improved drinking water treatment.
