Water Quality - Inequality: A non-Targeted Hotspot Analysis for Ambient
Water is an essential life sustaining resource tied to many socio-environmental needs and values. Although water has been a focal point of many environmental justice studies, ambient water quality (i.e. water quality before the tap) has been overlooked, resulting in only a partial understanding of how water quality may correlate with marginalized communities and ecosystems. In this presentation, data from the U.S. Environmental Protection Agency STORET database and the 2010 U.S. Census are analysed to identify poor ambient water quality within marginalized communities. For our purposes, final contaminants used for analysis included mercury, lead, copper, zinc, nickel, and fluoranthene and we defined marginalized communities by race and income (e.g. non-white and low-income). Hotspot analyses, Ordinary Least Squares, and the Geographically Weighted Regression, identify environmental justice cases across our target area of the Southeastern USA. High densities of hotspots in localized areas indicate that marginalized communities are significantly impacted by copper, lead, and mercury contamination. Race correlated more strongly with poor ambient water quality than community income levels. Results suggest our approach and analyses are effective for identifying environmental justice issues across large spatial scales.
