Students conduct impact studies at local sewage treatment plant

High school Environmental Science students take water samplesOn November 5, students from Mr. Touw’s AP Environmental Science class completed a study of water quality and the impact of treated sewage discharges in the Wawayanda Creek. Students examined the condition of the stream both above and below the Village Wastewater Treatment Plant to determine if there was a significant difference in chemistry or biology.

Students examined the Physical parameters of Temperature change, pH, Nitrates, Phosphates, Dissolved Oxygen, Ammonia, and total alkalinity and chloride using test kits and meters. Fecal Coliform samples were collected and measured after five days of bacteria growth on Bio-Paddles. Using D-frame nets, a benthic macroinvertebrate count was recorded to determine species diversity at each site.

The results of our findings and an analysis comparing the three sites (upstream, middle, and downstream) will be completed and released on November 24.

A river study of the effectiveness and impact of treated sewage discharge into the Wawayanda Creek is a required portion of the AP Environmental Science curriculum and has been completed every year by students at Warwick for the last 10 years. The Sewage Treatment Plant in Warwick has been in operation for nearly 40 years.
