Biological analysis is used to rapidly assess water quality and investigate the sources of pollution. This is done in accordance with the EPA’s Q-value system or the Western River Basin District’s Small Stream Risk Score (SSRS), and ISO standards.

These tests involve the analysis of macroinvertebrate populations and provide a rapid and accurate assessment of ecological water quality. For this reason, a Q-Value is frequently used where impacts to a water course may occur as a result of a proposed development.

The Atlantic salmon is commonly used as an indicator species for the health of a river. OPENFIELD can assess stretches of river for its potential as Salmon habitat. Habitat can also be assessed for its value for other important species such as Otter and Lamprey.
