My map synthesizes publicly available data from key sources to provide a spatial view of PFAS detection across NJ:

U.S. Geological Survey (USGS): Provided crucial monitoring water sample data, particularly for groundwater and regional studies.

NJ Department of Environmental Protection: Likely included data on public water system detections and state-level regulatory findings.

This visualization doesn't just show locations, it provides a spatial context for the contamination, helping to identify areas with elevated concentrations of PFAS, such as the relationship between concentration levels and potential contaminant sources and also geographic gaps where further monitoring efforts may be needed.
