How wells are polluted Wells may become polluted from two sources (a) from underground waters, and (b) from surface drainings near the well. Underground pollution may travel some distance and results from contamination introduced at some distance away, such as through a cracked limestone formation. Surface pollution happens when drainage from the soil, from rain-water or splashings may be carried directly into the well by a loose top or poorly constructed sides. Filth of all kinds may be left on the well top by dirty boots, etc., and then later washed into the well. This is a common occurrence, especially where the well top is made of boards, and the sides are of loose stone or brick.
