Water Quality and Ecosystem Monitoring

The video discusses the Occoquan Watershed Monitoring Laboratory in Northern Virginia, operated by Virginia Tech. It highlights the lab's 50-year history of water testing to support potable reuse efforts. The video covers various water sampling techniques, including conductivity, turbidity, and chlorophyll sampling. It also addresses monitoring tributaries and wastewater treatment impacts. A significant focus is on the rising salinity in water due to urbanization, emphasizing the need for community involvement in protecting water supplies.
