Abstract

The EPA has developed a set of draft methods that states and authorized tribes may use to derive field-based ecoregional ambient aquatic life criteria for specific conductivity, a measurement of ionic concentration, in flowing waters. The EPA's methods provide flexible approaches for developing science-based conductivity criteria that reflect ecoregional- or state-specific factors. Once final, states and authorized tribes located in any region of the country may use the methods to develop field-based conductivity criteria for flowing waters. The draft document provides a scientific assessment of ecological effects and is not a regulation.
