You can help reduce exposure to lead in drinking water by identifying the material of your water service line and reporting the results.
门罗县水务局致力于提供高质量的水, reliable water supply to the communities we serve that meets or exceeds all state and federal water quality regulations. Water provided by MCWA is lead-free when it leaves our treatment plants; however, it can come into contact with lead as it flows through lead-containing household fixtures, 家庭管道, 还有连接公共系统和你家的服务线路. In December 2021, the United States 环境 Protection Agency’s (USEPA’s) 铅和铜规则修订 (LCRR) went into effect with the purpose of further reducing exposure to lead and copper in drinking water.
The 门罗县水务局 takes the issue of lead in water very seriously. Exposure to lead can be harmful to people of all ages, particularly for infants and children. 这就是为什么MCWA致力于为无铅的未来而努力. 使之成为可能, we need your help to identify any remaining lead or galvanized service lines in our area.
A water service line is the small diameter pipe that connects your home to the larger diameter distribution system water main typically located in or adjacent to the street.
Water service lines are owned in part by the MCWA and in part by you, the customer. The diagram to the right shows the delineation of the MCWA and homeowner’s responsibility for the service line. The MCWA is responsible for repair or replacement of the section of water service line located between the distribution system water main and the curb stop or shut-off valve typically located at the property or right-of-way line. The customer is responsible for the remaining section of water service line from the curb stop to the water meter.
Typically, water service lines are composed of either copper and/or plastic pipe materials. In the past, however, lead and/or galvanized steel were also used for service lines. 由铅管组成的服务管线可能是水中铅的来源. Service lines composed of galvanized steel can also be a source of lead in water since lead particles can attach to the inside of the galvanized steel pipe. 1986年，美国禁止使用铅管, and plumbing materials were required to meet federal “lead-free” specifications after this date.
The MCWA has been testing the public water supply for lead since 1992 as required by the USEPA’s original Lead and Copper Rule (LCR) regulations. We can say with certainty that the water that leaves our treatment plants does not contain harmful levels of lead. 自1992年开始测试以来, we have consistently been substantially below the regulatory lead concentration action level of 15 parts per billion. MCWA has also been replacing any MCWA owned lead service lines found in the public water system since the original LCR regulations were issued by the USEPA in 1991, 尽管这不是必须的.
最近, MCWA expanded its Service Line Inventory efforts to enhance the inventory of water service material and identify any remaining lead or galvanized service lines throughout our service area. 这包括现场的服务线检查, as well as enlisting the assistance of property owners to identify their internal service lines (see “你能做什么?” 后面的一节). Customers may see the MCWA and its contractors identifying water service line materials by conducting small excavations in the vicinity of curb boxes, which are typically located near the property or right-of-way line in the front yard. Customers will be notified prior to and following the investigation if any action is required on their part.
Because water service line ownership is shared between MCWA and the property owner, 客户的参与对我们减少铅暴露的努力至关重要.
We need your help to identify the material of your portion of the water service as it enters your home. 拿一块磁铁, 一枚硬币, and a flashlight and follow the video instructions below to determine the material of your service line. PDF格式的说明是可用的 在这里.

- 每天冲洗 -任何时间的水不使用几个小时(6或更长时间), flush your cold water pipes by running the water until it becomes as cold as it will get; this typically takes between 30 seconds and two minutes. 这将把新鲜的水从街上的总水管引到你的水龙头, minimizing the amount of time any lead containing plumbing or fixtures are in contact with the water being used. After flushing, use the water for cooking or drinking, or save it for later use by filling pitchers. To conserve water, save the water from flushing the tap for watering plants or doing dishes.
- 使用冷水 -饮用或烹饪用水时, 只使用冷水, 尤其是在准备婴儿配方奶粉时.
- 投手过滤器 – T在这里 are filters available that can be installed to remove particulate lead. 如果你买了, we recommend you obtain one that has the National Sanitation Foundation’s “NSF 53” certification and follow the manufacturer’s recommendations for its maintenance. 在这里了解更多关于过滤器的信息: http://info.nsf.org/Certified/dwtu/listings_leadreduction.asp.
- 清除含铅的固定装置/管道 – The surest way to reduce exposure to lead in water is to remove and replace any fixtures or plumbing containing lead. 合格的水管工可以告诉你是否有铅管道, 检查内部管道中的铅焊料, look for fixtures containing lead and provide you the best information about replacement options and costs.
