“…The salts are easily washed downstream, buE upon enLering lakes or bays, their effects can be much longer lasting. Bubeck, et al (1971), and Diment, et al (1973), exarnined the effects of de-icing salt runoff on a bay in Rochester, New York, and found that the chloride concentratioo had increased five-fold during Ehe previous 20 years. A buildup of dense saline layers in the bay prevented complete verEical nixing in the spring and, as a result, the lower layers of water were wichout oxygen for nany monEhs.…”
