In the past year, North Attleboro High Schools’ environmental science class has been conducting an intense study of the Ten Mile River. The focus of our study is to find out detailed information regarding the biological, physical, and chemical state of the river.

The Ten Mile River is the main river within North Attleboro. It runs down to Narragansett Bay and flows through many other local towns. The river begins at Cargill Pond in Plainville and flows 23 miles through North Attleboro, Attleboro, Plainville, and Seekonk before going into Rhode Island.

We studied two sites along the river within Bristol County. The sites were Cottage Street and Cedar Street located in North Attleboro. Both sites were upstream of the wastewater treatment plant. Cottage Street is in the center of a high-density residential area and located just downstream of the Fuller Street bridge. Cedar Street site was at the bridge.

We only visited each site once on the river. We compared the two sites with pH testing, E Coli testing, Temperature testing, Dissolved Oxygen testing, Nitrogen testing, Fecal Coliform testing, Specific Conductivity and Benthic Macro-Invertebrate testing. The results show that the two locations we tested are not very different. They all met the Massachusetts Class B values for warm water.

We concluded that the Specific Conductivity should be watched at both sites. In March of 1998, the EPA tested for Specific Conductivity at the Cedar Street site and the value was 130uS/cm. In October 2004, the Cedar Street site level was around 300uS/cm. In six years the level of Specific Conductivity increased 170uS/cm.
