North Attleboro High SchoolEnvironmental Science River Study Presented by Donna Cochrane NSTA National Convention March 27, 2008
Research Design • Use Bridgewater State College’s Watershed Access Lab protocols • Testing is done for: • Depth and Flow (to determine volume of water) • pH, Temperature, Dissolved Oxygen (DO), % DO, Specific Conductivity • Nitrogen Nitrates (N-NO3) and Soluble Reactive Phosphorus (SRP) • Fecal Coliform and Macro-Invertebrates
Massachusetts Class Standards for Warm Water • Students determine the parameters that the state uses for the river we are studying • For Example…on a Class B river… • Temperature shall not exceed 28.3°C • Dissolved Oxygen to be 5.0 mg/L or higher • Percentage of Dissolved Oxygen should not be lower than 60% • pH values to be between 6.5 and 8.3 • N-NO3 values are to be less than 1 mg/L (EPA) • SRP (Soluble Reactive Phosphorus) levels are to be under 0.1 mg/L (EPA) • Specific conductivity should not exceed 800 uS/cm (EPA) • Fecals should not exceed 200 Fecal Colonies per 100 mL
Data Comparisons Students compare their data with State River Class requirements using Microsoft Excel for graphs.
Land Use Map • Picture of Land Use map made using ArcView software
Color Orthographic Imagery • MassGIS data or Google Earth Cottage Street Cedar Street
Bridges History of Surroundings • New bridges built • Neighbors fertilize yard before precipitation • Snowmelt/Salt • Channelization • Town water supply • Riparian zones cut down with Homeland Security Grant money • Dams – water releases • Waste Water Treatment Facilities
School Liaisons • Administration – Department Head, Principal, and Assistant Superintendent • Technology Department • Faculty • Heritage Day at the Middle School
Community Relationships • YMCA – loaned vans and adult driver • North Attleboro/Plainville Rotary presentations • North Attleboro DPW – Field Trips to Waste Water Treatment/Water Treatment Facilities • Pawtucket Water Board – permits monitoring of Class A river (Pawtucket, RI water supply) • Local Newspapers – The Sun Chronicle and Free Press…great press for students • EPA Speaker (Doug Heath) – discussed road salt and salinity
Funding • YMCA grant for chest waders • North Attleboro/Plainville Rotary • North Attleboro Educational Foundation • North Attleboro School System
Response to Course • Parents are happy that their children have the opportunity to take this course. • Students with an interest in fishing, animals, and the outdoors/camping are attracted to the course. • Students use the experience to pursue other avenues…for instance…
