新奥尔良的铅管污染了70%的住宅,尽管不断进行升级和推迟监管,但浓度水平高达100x联邦限额。 Lead pipes in New Orleans contaminate 70% of homes, with levels up to 100x federal limits, despite ongoing upgrades and delayed regulations.

新奥尔良自来水中的铅污染在2022年至2025年的全市测试方案中影响到70%的家庭,根据未公布的数据,大约是联邦限额的100倍。 Lead contamination in New Orleans tap water affects 70% of homes in a citywide testing program from 2022 to 2025, with some levels 100 times the federal limit, according to unpublished data. 旧的铅管已超过一个世纪了,尽管房屋内部进行了升级改造,但老旧的铅管仍停留在城市的边上。 Aging lead pipes, many over a century old, remain on the city’s side of meters despite upgrades inside homes. 虽然下水道和供水委员会符合联邦标准,但专家说,没有任何铅水平是安全的,特别是对儿童而言。 Though the Sewerage and Water Board meets federal standards, experts say no lead level is safe, especially for children. 经更新的《铅和铜规则》将在2027年前将行动水平降至10 ppb,并要求在2037年前完全更换管道,但由于成本、合同问题和有限的测试,进展缓慢。 The updated Lead and Copper Rule will lower the action level to 10 ppb by 2027 and require full pipe replacement by 2037, but progress is slow due to cost, contract issues, and limited testing. 居民仍然面临风险,官员们因外联和行动不足而面临批评。 Residents remain exposed, and officials face criticism for insufficient outreach and action.
