The Environmental Protection Agency has developed regulations which requires all water systems in the United States to sample certain 6up扑克之星亚洲版homes for the presence of lead and copper. These samples can only be taken from 6up扑克之星亚洲版homes built after 1982 and before June 1988. The EPA targeted these 6up扑克之星亚洲版homes because lead solder used in the joints of copper pipes may have the tendency to leach lead into water. This leaching problem normally occurs in water standing in pipes for more than six hours or in water systems that do not provide for corrosion control. The City of Cumming Water System began corrosion control in their systems in 1988.
We need your assistance in order to comply with this Federal requirement. If you own a 6up扑克之星亚洲版home built between 1982 and 1988 and agree to participate in this study, Cumming Utilities will provide you with a sample bottle and ask you to collect a cold-water sample after the water has been standing in the 6up扑克之星亚洲版home plumbing for at least six hours. This may be done first thing in the morning or immediately after returning 6up扑克之星亚洲版home from work before any water is used at the 6up扑克之星亚洲版home. The samples will initially be taken once every 6 months and less frequently thereafter.
Your participation in this study is encouraged but is strictly voluntary. Please take a moment to download and complete the attached form (see above) to see if your 6up扑克之星亚洲版home qualifies for the testing and return it via US Mail or via email.
We want to assure you of our continuing and concerted efforts to provide safe drinking water to our community. Many laboratory tests are conducted by our staff on a continual basis to assure that the water we distribute to your 6up扑克之星亚洲版home meets and exceeds all water quality standards. In addition, the State of Georgia performs periodic checks of our drinking water quality.
If you have any questions, please call Cumming Utilities Water Production Division at 770-781-2026 or 770-781-2039. You may also contact me by email at firstname.lastname@example.org. We will be glad to answer any questions you may have.

LEAD and COPPER Legislative History
In 1986 Congress Amended the Safe Drinking Water Act, prohibiting the use of pipes, solder or flux that were not “lead free” in public water systems or plumbing in facilities providing water for human consumption. At the time “lead free” was defined as solder and flux with no more than 0.2% lead and pipes with no more than 8%.
In 1996 Congress further amended the Safe Drinking Water Act, requiring plumbing fittings and fixtures (endpoint devices) to be in compliance with voluntary lead leaching standards. The amendments also prohibited the introduction into commerce of any pipe, pipe or plumbing fitting or fixture that is not lead free.
In 2011 Congress passed the Reduction of Lead in Drinking Water Act (RLDWA) revising the definition of lead free by lowering the maximum lead content of the wetted surfaces of plumbing products (such as pipes, pipe fittings, plumbing fittings and fixtures) from 8% to a weighted average of 0.25%, establishing a statutory method for the calculation of lead content and eliminating the requirement that lead free products be in compliance with voluntary standards established in accordance with SDWA 1417(e) for leaching of lead from new plumbing fittings and fixtures.
The 2011 RLDWA also created exemptions in SDWA Section 1417 from the prohibitions on the use or introduction into commerce of “pipes, pipe fittings, plumbing fittings or fixtures, including backflow preventers, that are used exclusively for non-potable services such as manufacturing, industrial processing, irrigation, outdoor watering, or any other uses where the water is not anticipated to be used for human consumption” (SDWA 1417(a)(4)(A)). Also exempt are “toilets, bidets, urinals, fill valves, flus6up扑克之星亚洲版hometer valves, tub fillers, shower valves, service saddles, or water distribution main gate valves that are 2 inches in diameter or larger” (SDWA 1417(a)(4)(B)).
The Community Fire Safety Act of 2013 further amended the SDWA Section 1417 to include fire hydrants in the list of exempted plumbing devices.
