Maury River Tributaries (North)
How healthy are our northern tributaries?
Background: The 6th grade students in Mrs. Sarah Hockman's science classes test water samples from creeks and rivers that flow into the Maury River; most are in the northern half of the County. The students bring the samples to school and test the samples in the classroom using LaMotte test tablets. They monitor these tributaries in fall, winter, and spring to see if there are changes with the seasons. Below are the results and their own written analyses of the data.

Summer Summary: These samples suggest water quality is pretty good. Phosphate levels were high.
Fall Summary: Over the 3-month time period, water quality stayed the same with the exception of nitrogen fertilizer levels (they went up :() Non-harmful bacteria found in Brattons Run.

Summer summary: Water quality is good. Turbidity, dissolved oxygen, pH, and nitrogen fertilizer (except Marl Creek) levels were good. Phosphate levels could improve.
Fall summary: Over a 3-month period, water quality has improved in all areas except one. pH and turbidity numbers were good. Nitrogen and phosphorous levels were down. Dissolved oxygen levels were down. We found non-harmful bacteria in Lake Robertson and Marl Creek.

Summer Summary: Water quality was good. Turbidity, dissolved oxygen, nitrogen (except Hays Creek), pH levels were good. Phosphate fertilizer levels could improve.
Fall Summary: Over the 3-month time period, water quality stayed the same. pH, dissolved oxygen, and turbidity levels were good (Dairy Farm was turbid). Nitrogen fertilizer levels stayed the same (Dairy Farm was high). Phosphate levels went down and the Dairy Farm had 0 phosphate. There was no trace of e. coli bateria in Hays Creek; however, traces of e. coli were in the Dairy Farm water.
