    Apple Orchard Park - Mendota Creek by Amy Brewer

    This spot is at the end of the creek's run through town. My other observations are at the creeks entry into town and then a few miles away from town. I hope to see if there is any significant difference after passing through the lake, and through town, and then through the farm fields a few miles. Site # R0415502

    Lake Kakusha by Amy Brewer

    This is the starting point for the creek that runs through town and feeds the Little Vermillion River. This sample was taken two days before a big winter storm. I will collect again after the storm to record any change in chloride from the salt the street department uses to help keep roads usable from the big storm's ice/snow

    Although 33ppm were entered for the chloride value, the actual value was slightly less, because 33ppm were the lowest value on the conversion table.
