Abstract: Assessment of impacts on water quality attributes is an essential
component of environmental impact assessment (EIA) required for the planning of
all major road projects. Most of the parameters involved for assessing impact
on water quality attributes are spatial in nature and for a rational assessment
it is necessary to quantify the impacts on individual attributes considering
their spatial variations. In this paper a methodology is demonstrated with
reference to a case study of highway development project in India, for the
quantification of impact on individual water quality attributes. The spatial
variation of impacts is captured with the help of Geographic Information System
(GIS).
Keywords: Spatial assessment, water quality, highway project, quantification of impacts
