The WSA does not compare water quality conditions at its sample sites to state water quality standards, but rather to biological reference conditions (the best available sites) determined based on a defined set of scientifically-based decisions. The data collected are available for states to analyze, along with other available data, using their methodologies for assessing attainment of state water quality standards.
