Key TakeawaysBecause it can accumulate lead in its scale, galvanized iron pipe (GIP) poses compliance challenges in the Lead and Copper Rule Revisions (LCRR) and proposed Lead and Copper Rule Improvements (LCRI).To prepare for the LCRR/LCRI, utilities can use the GIP corrosion control toolbox outlined here, including targeted sampling, scale analysis, and corrosion control treatment testing.GIP investigation and management can improve water quality, protect public health, and minimize aesthetic discoloration issues.The proposed LCRR/LCRI tap sampling changes mean that GIP could contribute to Action Level exceedances for the first time.

旧镀锌铁管有什么新变化？实用工具箱

要点由于镀锌铁管 (GIP) 会在规模上积累铅，因此在铅和铜规则修订 (LCRR) 以及拟议的铅和铜规则改进 (LCRI) 中带来了合规性挑战。为了准备 LCRR/LCRI，公用事业公司可以使用此处概述的 GIP 腐蚀控制工具箱，包括有针对性的采样、结垢分析和腐蚀控制处理测试。GIP 调查和管理可以改善水质、保护公众健康并最大限度地减少美观变色问题。拟议的 LCRR/LCRI 水龙头采样变化意味着GIP 可能首次有助于超出行动水平。
