PFAS Surface Water and Fish Tissue Monitoring

Ambient Fish Community Monitoring
Fish are an important component of aquatic life in rivers and streams in Connecticut. The DEEP Water Monitoring group therefore uses fish as one of three biological communities to evaluate the health of waterbodies in Connecticut. (The other two biological communities include benthic macroinvertebrates and diatoms.) Fish have the ability to move within a reach to find better water quality, but they can only do so if there is adequate water present and no barriers to their movement such as dams. Fish are therefore good ‘indicators’ of problems related to water quantity and habitat connectivity. Fish are more sensitive to changes in the amount of water in a stream than other biological communities such as benthic macroinvertebrates, and a fish community with very limited fish can often be a signal of flow-related water quality impairments.
Water Monitoring Data Availability
The DEEP Water Monitoring Group collects a large volume of data, statewide, each year. Data that have gone through the Agency's quality assurance and quality control (QAQC) review process are made publicly available through the following online databases.
Connecticut Healthy Waters Initiative
For several decades, the DEEP Monitoring Group has been building multidisciplinary datasets that include water chemistry data, physical habitat assessments, and biological information. The primary purpose for these data is to support water quality assessments. In addition, through multiple partnerships, the Monitoring Group is using these data to improve our understanding of healthy waters in Connecticut
2014 Volunteer Water Monitoring Conference
The 2014 Volunteer Water Monitoring Conference was held on July 25, 2014 at Goodwin College in East Hartford, CT. The conference was the first such conference to be organized by the CT DEEP to celebrate volunteer water monitoring in Connecticut. More than 100 individuals attended representing individual volunteers (citizen scientists), watershed group leaders, municipal commissioners, college and university professors, state and federal scientists, students, and representatives from the environmental consulting industry. In total more than 40 volunteer monitoring groups were represented at the conference!
