Better Assessment Science Integrating point & Non-point Sources

BASINS is a multipurpose environmental analysis system designed for regional, state, and local agencies that perform watershed and water quality-based studies.

Natural attenuation of dissolved solvents

BIOCHLOR is a screening model that simulates remediation by natural attenuation of dissolved solvents at chlorinated solvent release sites.

Simulate biodegradation of hydrocarbons at petroleum fuel release sites

BIOSCREEN is a screening model that simulates remediation through natural attenuation of dissolved hydrocarbons at petroleum fuel release sites.

Water Quality Models and Tools

DFLOW 3. 1 is a Windows-based tool developed to estimate user selected design stream flows for low flow analysis and water quality standards.

Model Water Distribution Piping Systems

EPANET is software that models water distribution piping systems. EPANET is public domain software that may be freely copied and distributed.

Industrial Waste Management Evaluation Model

The Industrial Waste Management Evaluation Model software is designed to assist you in determining the most appropriate waste management unit design to minimize or avoid adverse ground water impacts.

Remediation Evaluation Model for Chlorinated Solvents

REMChlor, or Remediation Evaluation Model for Chlorinated Solvents, is an analytical solution for simulating the transient effects of ground water source and plume remediation.

Wastewater Treatment Model

WATER9, the wastewater treatment model, is a Windows based computer program and consists of analytical expressions for estimating air emissions of individual waste constituents in wastewater collection, storage, treatment, and disposal facilities; a datab
