Potential sources of contamination

DMR: The Discharge Monitoring Report Pollutant Loading Tool

Who is discharging in your watershed? What pollutants are they discharging and how much? This tool calculates pollutant loadings from EPA’s Integrated Compliance Information System for the National Pollutant Discharge Elimination System (ICIS-NPDES).

ECHO: Enforcement and Compliance History Online

Information and maps of facilities regulated by EPA, including history of inspections, enforcement, and violations.

SPARROW

Use USGS models to estimate the origin, fate, and transport of nitrogen and phosphorus in river networks across the US.

CASE STUDY: Merrimack River

The Merrimack River is a source of drinking water for 600,000 people in New Hampshire and Massachusetts. Sometimes referred to as the “cradle of the American industrial revolution,” the river hosted the first large-scale factory town in the country and continues to support industrial activity along the river. To be better able to respond to chemical spills–such as the January 2014 spill of the chemical MCHM into the Elk River in West Virginia–EPA Region 1, the Massachusetts Dept. of Environmental Protection, and the New Hampshire Dept. of Environmental Services Drinking Water Programs initiated a coordination effort between states, EPA, and local emergency responders. The partners are planning to target above ground storage tank (AST) inspections, encourage spill response planning, and host spill response exercises. The initiative will include workshops with participation from AST owners, city officials, and public drinking water suppliers.

Contaminant Toxicity

WCIT: Water Contaminant Information Tool

WCIT is a directory of information on contaminants of concern to drinking water, including response guidelines and treatment options. This information is sensitive and password-protected. Access is granted to drinking water and wastewater utilities, State Primacy (primary enforcement) Agencies, and federal officials, including government laboratory personnel.

CAMEO Chemicals

Critical response info for thousands of chemicals. Includes physical properties, health hazards, recommendations for firefighting, first aid, spill response, and hazardous materials transport.
