Purpose of the Study
This study was done to test the Ten Mile
River. A series of chemical, physical, and
biological tests were performed at two
different sites along the river to see if the
Ten Mile River fits the Class B Warm Water
Standards as set forth by the State of
Massachusetts.

Possible Reasons for the Results
There were 1.11 inches of rain in the days prior to our study.
There are bridges located near our two sites and runoff from
those bridges flows into the river.
The rivers banks are highly urbanized, meaning that there
are many houses and buildings surrounding the river.
Cottage St. site had trees on one side, grass on the other.
Cottage St. site was channelized with concrete that was
eroding.
Cottage St. site was missing a riparian zone to stop any
fertilizers from entering the river.
Geese populations are a large problem in North Attleboro at
Falls Pond, upstream from Cottage St.
