INTRODUCING THE FRESHWATER EXPLORER: A NATIONAL VIEW OF BACKGROUND AND MEASURED CONDUCTIVITY
The Freshwater Explorer is an interactive map interface that allows users to compare predicted natural background with measured ambient stream conductivity. It allows users to visualize the relative freshness of streams across the contiguous United States or within a network of streams. The potential impact of salinization of streams can be explored by the relative difference between measured ambient stream conductivity and predicted natural background or predicted biological effect thresholds. The Freshwater Explorer is built upon two models: a Natural Background Model that estimates natural background conductivity from empirical geology, soil, climate and other data and a Background-to-Criterion model that estimates a conductivity level leading to 5% loss of aquatic life. The ambient measured data were extracted from the EPA Water Quality Portal (WQP). This platform is particularly useful for spatially characterizing freshwater and considering potential sources and solutions to mitigate salinization of freshwater.
