NOAA N-SPECT Comparison Tool (Clearinghouse)


Use the Nonpoint-Source Pollution and Erosion Comparison Tool (N-SPECT) to investigate potential water quality impacts from development, other land uses, and climate change. N-SPECT was designed to be broadly applicable, but the tool operates most accurately in medium-to-large watersheds having moderate topographic relief. Training and live technical assistance are available for this tool.

This tool is GIS based and provides data on water quality impacts for watersheds. This tool would likely not be used by public health departments, but more appropriately by local water districts.
