Annual Monitoring Reports

Ten tributary locations within the Pennichuck Watershed have been continuously monitored for flow and total phosphorus, along with other common contaminants, since 2007. Groundwater monitoring for total phosphorus at nine of the ten tributary sampling locations or nearby began in 2013 to help determine phosphorus loads coming from groundwater baseflow versus from stormwater runoff. Annual Reports are generated at the close of each year of sampling, beginning in 2008, and are archived below.
