Water Quality
Tools
- DFLOW: A Tool for Low
Flow Analysis
This website contains a link to download DFLOW 3.0, a tool to calculate
design flow statistics. It also includes several pages explaining how
to use the tool and provides detailed background information.
- Analytical Methods
Methods used by industries and municipalities to analyze the chemical
and biological components of wastewater, drinking water, sediment, and
other environmental samples.
- Water Quality Models
Tools for simulating the movement of precipitation and pollutants into
receiving waters.
- Economics & Benefits
Estimating the benefits of EPA water quality programs.
- Training
Lists training opportunities in the Office of Water.
- Mercury Maps: A Quantitative
Spatial Link Between Air Deposition and Fish Tissue
Mercury Maps is a tool that relates changes in mercury air deposition
rates to changes in mercury fish tissue concentrations, on a national
scale. Mercury Maps can be used to help evaluate the benefits of technology-based
air emission reduction standards or to perform Total Maximum Daily Load
(TMDL) analyses for individual or multiple watersheds.
- Allocating
Loads and Wasteloads
Use this tool forTMDL development.
- National Fish Tissue
Study
EPA is conducting a screening-level study to estimate the national distribution
of selected persistent, bioaccumulative and toxic chemical residues
in fish tissue from lakes and reservoirs of the continental United States.
