  1. Abbott Run Annual Study 2009 North Attleboro High School Presented 4/30/09 Bridgewater State College

  2. Purpose of Study -The purpose of our study is to examine whether or not the water in Abbott Run is suitable to be Pawtucket, Rhode Island’s drinking water. -We checked for fecal coliform colonies, dissolved oxygen, the river flow, precipitation levels, pH, the benthic macro-invertebrates diversity, depth of the river sites, and temperature to see if the river would meet the standards of Massachusetts. -In Massachusetts, a river source must meet the Class A standards to be used for drinking water.

  4. There was a furnace built on the west side of the river and was called Iron Rust. Cannons were made here during the Revolution. Abbott Run is the water source for Pawtucket, RI and Cumberland, RI and has been for centuries. Robin Hollow, one of the first manufacturing sites in Cumberland, was located on Abbott Run. The first manufacturing done at Abbott Run was during the time of Charles II when a royal license was obtained to manufacture tar. There was a Girl Scout camp on the river called Camp Shady Pines. There was construction of Hunts Bridge near Abbott Run, Site B during 2006 which has disturbed the pH of the water. History of Abbott Run

  38. Summary of Results • Site A and Site B met the Massachusetts Class A standards. • Site A had slightly higher Nitrate and Specific Conductivity readings which we believe had to do with the rain the days before our site visits washing materials into the river from the golf course. • Both sites had considerably higher numbers of net-spinning caddisflies. These BMI have a higher tolerance to organic pollution. • The pH has returned to normal after the past two years of higher basic levels at both sites.
