DESCRIPTION
TRANSCRIPT
Background
• The Peckman River forms one border of our school. It’s a small river, about 8 miles long that flows into the Passaic River, which also runs through our community.
• Some of us swim and fish in the Peckman….gross!!!
Materials
1. Kick net2. D frame net3. CHEMets Nitrate chemical test4. CHEMets Dissolved oxygen test5. GPS6. Clarity tube7. Oakton Conductivity tester8. CHEMets Phosphate test9. E. coli test10. Dipper

Methods
• PH Test – Color indicator strips.• Oxygen Saturation – Water was tested for
Saturated Oxygen.• Conductivity – Was tested with an Oakton
conductivity tester.• CHEMets Phosphate Chemical Test –
Colorimetric analyses for Phosphate.• E. coli – Water tested for E. coli with Coliscan
Easygel.
Methods• Kick netting – We kick netted a 1 square meter around the
chosen riffled area, stirring up the substrate.• D – Frame net – The D- frame net was at the end of a pole
and used to swipe at the substrate in the river bed.• CHEMets Nitrate Chemical Test – Colorimetric analyses for
Nitrate.• CHEMets Dissolved Oxygen Test- Colorimetric analyses for
DO.• Water Temperature – Water was tested with a
thermometer.
