Health-Based Screening Levels for Evaluating Water-Quality Data

The Health-Based Screening Levels for Evaluating Water-Quality Data searchable online database provides Health-Based Screening Levels (HBSLs) for hundreds of chemicals, including pesticides and degradates. HBSLs are non-enforceable benchmark concentrations of contaminants in water. These screening levels supplement federal drinking-water standards and guidelines.
