EPA关于pfa的国家初级饮用水法规

Summary

保护公众健康是我们的首要任务. 门罗县水务局提供安全的饮用水, 高质量的, and in compliance with all federal and state water quality regulatory standards. 4月10日, 2024, the US Environmental Protection Agency (EPA) announced the final National Primary Drinking Water Regulation (NPDWR) for six concentrations of man-made chemicals called per- and polyfluoroalkyl substances, 或pfa, 在饮用水中. The EPA regulates the safe levels of more than 100 compounds 在饮用水中 under the requirements of the federal Safe Drinking Water Act.

什么是pfa?

pfa are a category of manufactured chemicals that have been widely used in industrial and consumer products since the 1940s. 例如地毯, 服装, 纺织品, 食品包装, 消防化合物, 以及其他许多现代工业产品. 有成千上万种不同的pfa化合物, 其中一些比其他的应用和研究更广泛. The EPA says some of these chemicals can cause serious 健康 problems if you are exposed to them over a long period of time, 或者在某些关键的人生阶段，比如怀孕和儿童早期. 大多数人通过消费品接触到这些化学物质. Drinking water can be an additional source of exposure in communities w在这里 these chemicals have entered the water supplies. In many areas of the country, pfa compounds are considered to be ubiquitous in the environment. pfa chemicals tend to break down slowly in the environment and can build up in people, 动物, 以及环境的变化.

新规定是什么?

在最后的规则中, 环保署设定了限制, 称为最大污染水平(MCLs), for the concentrations of five individual pfa compounds and one mixture of two or more pfa compounds. This mixture includes a group of four pfa compounds and is called a 风险指数, or HI. The 风险指数 is an approach that EPA uses to understand 健康 risks from exposure to a chemical mixture. The HI is a sum of fractions w在这里 each fraction compares the level of each pfa measured in the water to a 健康-based water concentration. mcl是饮用水中允许的污染物的最高水平. MCLs are set as close to maximum contaminant level goals as feasible using the best available treatment technology while taking cost of removal into consideration. mcl是可执行的饮用水标准. 新规定的pfa化学品和mcl如下所列.

该规则对公共供水系统有什么要求?

• 三年内(到2027年):
  • Complete initial pfa monitoring or obtain approval to use previously collected monitoring data.
• 三年(从2027年开始):
  • 启动例行合规监控.
  • Provide results data f或pfa monitoring in Annual 水质报告.
  • Start issuing public notification for any monitoring and testing procedure violations.
• 第5年(2029年开始):
  • 符合pfa最高污染物水平.
  • Provide public notification for violations of the pfa maximum contaminant levels.

Are t在这里 state regulations for concentrations of pfa 在饮用水中?

Yes. 8月20日, 2020, New York revised state Public Health Law and adopted new drinking water standards for public water systems that set maximum contaminants levels (MCLs) of 10 ppt for concentrations of PFOA and 卵圆孔未闭. The standards require public water systems to routinely monitor for PFOA and 卵圆孔未闭, 通知卫生部门和公众确认的超标情况, and work with 健康 departments on a compliance timetable and plan to reduce the concentration levels of these chemicals below the MCL.

在接下来的两年里, New York State will have to adopt requirements and apply for approval (known as primacy) to oversee implementation of the pfa NPDWR. New York must ensure that state regulations are no less stringent than the regulations promulgated by the EPA.

MCWA的饮用水中pfa的含量是多少?

The 门罗县水务局 performs quarterly water quality testing f或pfa compounds on our source waters, 经过处理的饮用水离开我们的水处理厂, and at entry points to our distribution system for water we purchase from the city of Rochester and Erie County Water Authority. All of MCWA’s water has tested below federal and state regulatory levels for measured pfa compounds. Summaries of these and all our water quality testing results we submit for compliance with federal and state water quality regulations can be viewed 在这里.

MCWA对饮用水中的pfa做了什么?

The drinking water we supply remains in compliance with federal and state water quality standards and regulations. We recognize concentrations of pfa compounds 在饮用水中 is an important concern for customers. 这就是为什么需要更多的研究和投资. 具体而言，我们力求:

• Continue robust testing and monitoring for levels of pfa in our water.
• Develop understanding of other established and emerging treatment options.
• Develop practical and feasible strategies to reduce levels of pfa w在这里 and when testing shows concentrations above regulatory standards.

Again, public 健康 and the quality of your drinking water is our top priority.
