美国环保局根据1986年《安全饮用水法修正案》颁布铅和铜规则已经整整一年了。到目前为止，许多水系统运营商将完成自来水监测要求，并将认真考虑腐蚀处理方案。本文将介绍一些新英格兰社区收集的最新腐蚀控制数据，这些社区在腐蚀控制计划中选择了碱度补充碳酸氢钠（NaHCO3）。个人系统经验从15年到6个月不等。将提供严格遵守EPA协议获得的铅和铜数据。

It has been a full year since the USEPA promulgated the lead and copper rule under the Safe Drinking Water Act amendment of 1986. By now many water system operators will have completed the tap water monitoring requirements and will be giving serious consideration to a corrosion treatment program. This paper will present new and updated corrosion control data collected on some New England communities who have chosen alkalinity supplementation with sodium bicarbonate (NaHCO3) in their corrosion control programs. Individual system experience ranges from 15 years to six months. Lead and copper data, obtained under strict adherence to EPA protocol, will be presented.
