Software
The USGS has developed software that is routinely used by federal, state, and public land managers. The USGS uses this software as wells as software developed by other agencies to support its science work.

SPARROW modeling: Estimating contaminant transport
SPARROW (SPAtially Referenced Regression On Watershed attributes) models estimate the amount of a contaminant transported from inland watersheds to larger water bodies by linking monitoring data with information on watershed characteristics and contaminant sources.
Chemical Mixtures Software
The chemical mixtures software is a collection of computer programs for investigating the composition, occurrence, distribution, and potential toxicity of chemical mixtures. The software is designed to assist with selecting specific mixtures for future research, identifying the causes for the occurrence of specific mixtures, and discovering the effects of mixtures.
CE-QUAL-W2 - Hydrodynamic and Water Quality Model
CE-QUAL-W2 is a water quality and hydrodynamic model in 2D (longitudinal-vertical) for rivers, estuaries, lakes, reservoirs and river basin systems. W2 models basic eutrophication processes such as temperature-nutrient-algae-dissolved oxygen-organic matter and sediment relationships.
SELDM: Stochastic Empirical Loading and Dilution Model - Software page
Overview
The Stochastic Empirical Loading and Dilution Model (SELDM) is designed to transform complex scientific data into meaningful information about the risk of adverse effects of runoff on receiving waters, the potential need for mitigation measures, and the potential effectiveness of such management measures for reducing these risks.
