Under the leadership of Ruth Indrick (right), Georgetown Conservation Commission member and Kennebec Estuary Land Trust Coodinator, and with the help of grant funding from NOAA, Georgetown volunteers starting in 2013 have taken detailed measurements of water quality at nine locations around Georgetown. Temperature, salinity, clarity, dissolved oxygen and pH (acidity) are recorded biweekly at high tide from May through October. These readings are collected by the DEP and used by shellfishermen and others to monitor the health of coastal and estuary waters as well as add to the understanding of changes over time. Phippsburg volunteers collect the same information at ten sites along the Kennebec on the Phippsburg side.
