摘要一个2000万吨的钢厂渣场的渗滤液对宾夕法尼亚州西部一条小溪Nine Mile Run的化学成分产生了重大影响。碱度、酸度、pH、钙和镁被从95公顷的渣场脚趾渗出的碱性渗滤液显著改变。这些渗滤液使接收水流的平均酸碱值从7.7提高到9.3，测得的最高酸碱值为11.1。碱度降低，Ca~(++)和Mg~(++)从溶液中出来，在河床上方形成碳酸盐流石层。
ABSTRACT Leachate from a 20 million ton steel mill slag dump significantly influenced the chemistry of a small western Pennsylvania stream, Nine Mile Run. Alkalinity, acidity, pH, calcium, and magnesium were significantly altered by the alkaline leachate that seeped from the toe of the 95 hectare slag dump. These leachates increased the mean pH of the receiving stream from 7.7 to 9.3, and the maximum pH measured was 11.1. Alkalinity decreased, and Ca++ and Mg++ came out of solution forming carbonate flowstone-like layers over the streambed.
