Your role: You will measure water quality parameters bi-weekly and record this data for presentation to the Ravenna Creek Alliance.

Hours per week:

Site visits occur every other week. Times are arranged each quarter to accommodate SSL student schedules. The total transit, sampling, and analysis time is estimated at 3 hours.

Type of class activity:

SSL students perform nine water quality tests during each sampling period. Some tests are performed in the field (dissolved oxygen, pH, temperature, conductivity, and turbidity), whereas others require additional analysis in the laboratory (NO3-, total PO4-3, biochemical oxygen demand, and fecal coliform). The students also sample benthic macroinvertebrates once each quarter. Results are recorded from each visit to maintain a long term data record.
