The NECB urban-gradient study is designed to examine
how increasing urbanization influences water quality and stream
health. The study is investigating how biological, chemical, and
physical characteristics of streams change as urban land-use increases.
Thirty-one sites in southern Maine, southern New Hampshire, and
eastern Massachusetts are included in the study. One additional
site is located in central Connecticut that links to Project NEMO
(Non-point Education for Municipal Officials) work in that state.
These 32 watersheds represent a complete range of urbanization.
Physical, chemical, and biological characteristics of all 32 rivers
were monitored in 2000. Data were collected on continuous streamflow
discharge or stage, water temperature, concentrations of nutrients
and pesticides in stream water, and macro invertebrate, algal,
and fish community structure. Report preparation is planned for
2004.
