Water - the NEMO Program

CLEAR’s NEMO (Nonpoint Education for Municipal Officials) program has been working with communities to protect water quality through better land use since 1991. At present, our main focus in on helping Connecticut communities respond to the “MS4” stormwater general permit, which was expanded in 2017. And we have developed various tools to help protect our waterways, like the NEMO Rain Garden smartphone app, and the N-Sink tool, to determine areas in a watershed that are important for reducing nitrogen pollution. Recently, we have developed the Stormwater Corps, deploying trained undergraduates to perform stormwater retrofit analyses for towns (see also our STEM portfolio).
