The Eighth Grade of the Franklin School of Innovation studied the various parameters of Hominy Creek. These parameters were Nitrates (No3), Dissolved Oxygen (DO), pH, Phosphates (Po4), Turbidity, Temperature (Temp) and the Flow Rate, contrasted to the weather for the day. Macroinvertebrates were collected and identified before being released. E. Coli tests were taken and analyzed during this period. Data was collected for 14 days, from March 22nd to April 19th. Tests were collected at 35.540477 degrees North, 82.630827 degrees West. These trials were conducted for one reason: to test the health of Hominy Creek. The indicators of Nitrates, Phosphates, PH, Flow, Temperature, etc. all show the pollution levels, or lack thereof, in …show more content…
They were taken in a similar way to the nitrates, as they are related. The turbidity was taken with a Turbidity sensor and a Secchi disk icon. A bottle of water was inserted into the turbidity sensor, where light was refracted through it. This picked up on the cloudiness and the debris in the water. The disk icon tested the water by adhering the sticker to the bottom of a jar and filling the jar with water. The appearance of the disc would change to show the turbidity levels in the water. The temperature was measured using a thermometer. Lastly, the Flow Rate was calculated using a probe. It was measured at five to six locations across the stream. Lastly, the E. Coli was taken using Coliscan Easygel. Creek water was taken and poured into the gel, which was then incubated. The next day, it was analyzed to determine the levels of E. Coli, and whether they were below the safe limit for recreational …show more content…
These trends are Precipitation and Flow rate. It has been seen that rainfall will affect the stream’s speed. If precipitation increases, then flow will increase. Tests were taken and analyzed to see if results in Hominy Creek were similar to tests taken elsewhere. However, some data could be inaccurate for several reasons, one of which is that on days previous, past rain could affect flow for certain days, especially in the starting phase of the tests.
