St. Charles WQI Summary

            The water that was tested from the Fox River in St. Charles tested out relatively good. The overall WQI was 67.03. That data falls in the range of 50-70 (medium). The amount of dissolved oxygen was 81% saturated. The pH was 7.4, that is neutral. The temperature is also very cool so that there is enough oxygen for all types of creatures to live. The Only high amount of the test results was the total solids and the nitrates. Those were the lowest scores on the data chart. There was 1200mg/L of total solids. That can cause water heating and therefore a less amount of dissolved oxygen in the water. The phosphate level was rather high too. It was 4.3mg/L (Q-value 13), which makes it the lowest Q-value on the chart for St. Charles. It makes the water .52 better then the water at the Batavia area. Over all the other tests came out excellent. So the water is safe and the WQI is pretty good.
