REP 2020 Fall Monitoring

With many schools still operating virtually or in a hybrid environment, fall monitoring was a bit smaller than usual this year due to the COVID-19 pandemic.

**This page will continue to be updated as results come in**

The Education Manager was able to collect some chemical data from seven sites, and the following schools were able to safety monitor with small groups of students:
Huron Valley Lutheran High School, Westland
Steppingstone School, Plymouth
Crestwood High School, Dearborn Heights

Notes from the Manager: At each sampling site, I got the water temperature, collected a water sample for BOD by collecting the sample in a dissolved oxygen bottle and wrapping it in aluminum foil, collected and “fixed” a dissolved oxygen sample, got water samples for fecal coliform that were immediately placed in a cooler on ice, and ran the pH test. I also collected a plastic water bottle sample of river water to take back to the office to run the remaining tests. I was only able to collect samples from the shore using a plastic water sampling rod. No benthic or physical data were able to be collected.

Sampling conditions were ideal: normal/low water levels, beautiful sunny weather, and cooler temperatures.

I could not get the change in temperature readings due to time and logistical constraints.

Since nitrate values in the spring were so low at some sites in the spring, I purchased a low-range nitrate test. Other nitrate values were so high that I need to re-run a couple of the tests to be sure.

Shipping delays postponed the plating of the fecal coliform tests, I am still waiting on results.
