At the very to the lowest degree, Shi said, that means expensive maintenance may be needed more ofttimes. Maine, New York, Vermont, Virginia, and Wisconsin have the most detailed policies. High chloride ratios in the Flintstone River contributed to Michigan'southward lead drinking water crisis, and the aforementioned problem impacts smaller systems across the country as well, said Edwards, the adept who helped uncover Flint'south drinking water problem. Worse, when all that salt dissolves and washes away,it steadily accumulates in rivers and streams. The Northeast is a top contributor. Snow in SC is very rare.
