    Fox River Yorkville IL by Pat Gunnerson

    The river was very low which may account for the slight rise in chloride from the previous month. There appears to be a very slight difference in the results between the two test strips. However they were taken at the same time and did show the same results. I could not get a good photo that doesn’t show a slight difference in the results due to shadow.
