Abstract
Local decision makers need an unbiased process to determine small communities
at risk from inadequate wastewater treatment. The geographic information
system (GIS) enables decision makers to identify impacted communities and
establish a fair and equitable approach to allocation of resources for remediation
strategies. The use of GIS in this manner is demonstrated for Tennessee, USA,
but the methodology is applicable broadly. GIS was used to develop
methodology for identifying communities with a population of 10,000 or less in
which there existed public health, water quality and/or aesthetic impacts
associated with inadequate wastewater treatment. The GIS approach, normalized
by population, identified communities with the highest ranking problems, as well
as control communities that had no known health, water quality or aesthetic
problems due to inadequate wastewater treatment.
Keywords: rural communities, wastewater treatment, health risk, interaction of
social and environmental issues, geographic information system.
