    Lippold Park - West Entrance by Far Syed

    It was raining, while I was sampling, and it seems like the chloride levels were higher, compared to the other site I went to. It was getting chilly, rainy, and cold, so not sure how often the site was checked, to ensure the chloride levels were reduced!
