  1. Pecking through the Peckman River: an analysis of water quality Mr. Goodman's 2nd Period Ecology Class

  2. 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!!!

  3. Materials • Kick net • D frame net • CHEMets Nitrate chemical test • CHEMets Dissolved oxygen test • GPS • Clarity tube • Oakton Conductivity tester • CHEMets Phosphate test • E. coli test • Dipper 1 2 4 8 6 3 9 5 7 10

  4. 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.

  5. 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.

  7. Macroinvertebrates • Macroinvertebrates provide a broad range of information that could benefit the study of water quality. • A major link in the aquatic food chain. • They provide a good source of energy for fish and animals in the surrounding environment. • Another important role they play consists of sensitivity to water quality and pollution.

  8. Macroinvertebrates • At the source in Eagle Rock Reservation, we caught the largest variety of Macroinvertebrates. This discovery made it clear that the water quality was a lot better than any other location. • Unfortunately, we can not determine just how poor the water quality was at the mouth of the river and the sewage plant because we found very few Macroinvertebrates. • Our findings at PVHS gave us a little bit of insight about the quality of water; the Macroinvertebrates we collected had a moderate-high tolerance for pollution.
