EPA Releases Aquatic Life Benchmarks for Freshwater Species

This original announcement was published by the EPA on October 1, 2019 and can be access here. 

Today, EPA released the revised Aquatic Life Benchmarks table, which includes both new and updated aquatic life benchmark values.

State, tribal and local governments use these benchmarks in their interpretation of water monitoring data. Comparing a measured concentration of a pesticide in water to an aquatic life benchmark can be helpful in interpreting monitoring data and in identifying and prioritizing sites and pesticides that may require further investigation.

New aquatic life benchmarks represent newly available toxicity endpoints for registered chemicals. EPA’s goal is to add to these benchmarks on an annual basis.

EPA based these benchmarks on toxicity values found in scientific studies that the agency reviewed in support of publicly available ecological risk assessments and regulatory decisions. The table directly links the source documents for each of the benchmarks.
