Environmental Quality

The Environmental Quality Characterization for Hodgson Brook report Adobe Acrobat Reader Symbol(Morin and Jones, 2003) identified five priority pollutants based on historical information and technical data from previous studies. Technical reports and content from discussions with the Local Advisory Committee were used to develop a list of known or potential sources for each pollutant. Click on the list of five priority pollutants below to view the pollution category and its list of potential sources.

Please note that the sources shown at the top of each list generally have more scientific data or information to back up the listing. Sources mentioned lower in the lists have less scientific information to support the listing, but are listed based on outside studies, local knowledge or common assumptions.
