Protecting Rivers: OARS' Vital Water Science Studies

OARS conducts water science studies to safeguard the health of the Sudbury, Assabet, and Concord rivers, ensuring these vital waterways remain clean and vibrant. These studies are crucial for identifying and addressing pollution sources, monitoring water quality, and understanding the impacts of climate change. By collecting and analyzing data, OARS helps protect the rivers’ ecosystems, ensuring safe habitats for wildlife and maintaining the natural beauty and recreational value of these rivers. These efforts are vital for the communities that depend on the rivers for drinking water, recreation, and overall well-being, promoting a healthier environment for both people and nature.

Visit our water quality page to explore OARS’ ongoing water quality monitoring efforts, which have been conducted since 1992 with the help of citizen scientist volunteers. Learn about the major water quality issues affecting the Sudbury, Assabet, and Concord rivers, including eutrophication, dissolved oxygen levels, bacteria, phosphorus, algae, mercury, and invasive plants. Access in-depth findings from OARS’ water quality studies.

Learn about OARS’ monitoring and research of the SuAsCo rivers. Our studies are designed to ensure that management decisions are founded on reliable scientific data. We research different aspects of river health, such as water quality, streamflow, bacteria levels, conductivity, chloride, and the effects of wastewater treatment plant upgrades.

Annual River Health Insights

OARS’ Annual Water Quality Report is crucial for understanding the health of the Sudbury, Assabet, and Concord rivers, providing detailed data and analysis on water quality trends and pollution sources.

OARS’ Water Quality Reports provide science-based assessments of the Sudbury, Assabet, and Concord rivers, offering insights into trends and challenges affecting their health. These comprehensive reports highlight data from extensive monitoring efforts, including water temperature fluctuations, conductivity levels, dissolved oxygen trends, pH variations, and nutrient concentrations like total phosphorus and nitrate. They serve as essential resources for understanding the rivers’ ecological status, guiding informed management decisions, and community engagement efforts to protect these vital waterways.
