    Veteran Acres - Sterne Woods (Oakwoods Lodge) by Far Syed

    It was a nice open area without anything grown around it, and compared to the numbers from last month’s, this was less than the other one due to the weather since it was 62 degrees, but it was hot when the chlorine levels increased last month. The water was still nice, and a good day to be sampling!

    Lippold Park - West Entrance by Far Syed

    There were bugs around the area, so I put on bug spray, and then went toward the water to get the sample, but the weather was not too bad, 64 degrees, but last month, it was hot, so the chlorine levels were higher than this. The view was nice tho!
