根据现有信息，新奥尔良在2000年或2001年期间没有任何违反现行、未决或拟议国家标准的报告。新奥尔良的水含有氯消毒的副产品，可能导致癌症，并可能导致生殖和其他健康问题——包括三卤甲烷和卤乙酸，其含量低于国家标准，但大大高于国家卫生目标，特别是2001年在西岸。2001年，新奥尔良的浊度峰值接近新的国家标准；浊度是衡量水浑浊程度的一种指标，用于表明水可能受到隐孢子虫或其他对人类健康构成威胁的病原体的污染。新奥尔良偶尔会出现杀虫剂阿特拉津含量升高的情况，阿特拉津会损害主要器官，导致生殖问题和癌症。值得注意的是，新奥尔良市政府官员估计，老化的管道和基础设施的主要问题将需要“至少10亿美元的维修和改善”。据供水和污水处理委员会的执行主任说，这笔钱最终来自哪里还不完全确定。该市将供水系统的管理外包出去的努力没有成功，这引起了很大的争议。它导致了一项成功的投票措施，要求选民批准超过500万美元的私人合同。最终，私有化的努力在2002年失败了。这些报告一般都是可读的，并强调了最有可能因水问题对健康造成不利影响的人的信息。这些报告没有提供有关砷、阿特拉津、钡或镉水平的必要信息；包括关于城市水中铅的误导性语言；没有按照EPA的要求提供具体污染源的信息；也没有讨论发现的受管制污染物水平超过健康目标对健康的影响。新奥尔良水源保护等级很差该市的水源密西西比河易受无数工业和农业污染源的污染。
New Orleans had no recent reported violations of current, pending, or proposed national standards during 2000 or 2001, according to available information. New Orleans water contains by-products of chlorine disinfection that may cause cancer and, potentially, reproductive and other health problems— including trihalomethanes and haloacetic acids, found at levels below national standards but substantially above national health goals, particularly on the West Bank in 2001. In 2001, New Orleans had a peak turbidity level that approached the new national standard; turbidity is a measure of the cloudiness of water and is used as an indicator that water may be contaminated with Crypto-sporidium or other pathogens that present human health concerns. New Orleans occasionally has elevated levels of the pesticide atrazine, which can damage major organs and cause reproductive problems and cancer. Noteworthy New Orleans city officials estimate major problems with aging pipes and infrastructure will necessitate " at least $1 billion in repairs and improvements. " 1 Where that money ultimately comes from is not entirely certain , according to the executive director of the water and sewerage board. 2 An unsuccessful effort by the city to contract out management of the water system generated substantial controversy. It resulted in a successful ballot measure requiring voter approval for private contracts in excess of $5 million. 4 Ultimately, the privatization effort failed in 2002. The reports were generally readable and highlighted information for people most likely to experience adverse health effects from water problems. The reports did not provide required information on arsenic, atrazine, barium, or cadmium levels; included misleading language about lead in city water; included no information about specific sources of pollution as the EPA requires; and did not discuss the health effects of regulated contaminants found at levels in excess of health goals. New Orleans Earned a Source Water Protection Rating of Poor The city's source water, the Mississippi, is vulnerable to innumerable sources of industrial and agricultural pollution.
