The Massachusetts Water Watch Partnership (MassWWP) is a program of the Water Resources Research Center at the University of Massachusetts. From 1990 to 2012, MassWWP provided training and other technical assistance to citizen scientists who conduct water quality monitoring programs on the lakes, rivers, and estuaries of Massachusetts. Over this time, MassWWP collaborated with a number of local, state, regional, and national partners on a range of projects.
