Great Bay Coast Watch And Dover Stormwater Investigation For Potential Pollution Sources In Dover, Nh December, 2004 Final Report

The Great Bay Coast Watch (GBCW) is citizen volunteers, working within the UNH Cooperative Extension/NH Sea Grant Program, protecting the long-term health and natural resources of New Hampshire's coastal waters and estuarine systems through monitoring and education projects. In 2001, GBCW began work, with funding from the U.S. Environmental protection Agency though NH Department of Environmental Sciences, to assist the City of Dover, NH, in identifying its illicit storm water connections using fecal coliform as an indicator species. Sites located at Dover's storm drain discharges were screened for high levels of fecal coliform. Data will be provided to City of Dover staff to use to better assess their storm drain system and remove illicit connections. By the end of October 2004, monitoring results indicated that continued monitoring would not reveal new information. Samples were taken from 57 sites. Without including Quality Assurance/Quality Control samples, 28 samples were processed in 2003 and 25 samples were processed in 2004. This report describes and interprets the results of the study.
