The Safe Drinking Water Act (SDWA) is the principal federal law in the United States that ensures safe drinking water for the public. The law of the United States was originally largely derived from the Common law system of English law, which was in force at the time of the Revolutionary The United States of America —commonly referred to as the Water of sufficient quality to serve as drinking water is termed potable water whether it is used for drinking or not  Pursuant to the act, the Environmental Protection Agency (EPA) is required to set standards for drinking water quality and oversee all states, localities, and water suppliers who implement these standards. A state is a political association with effective Sovereignty over a geographic Area and representing a Population.
SDWA applies to every public water system in the United States. There are currently more than 160,000 public water systems providing water to almost all Americans at some time in their lives. SDWA does not apply to bottled water. Bottled water is Drinking water packaged in Bottles for individual consumption and retail sale Bottled water is regulated by the United States Food and Drug Administration under the Federal Food, Drug, and Cosmetic Act. The United States Federal Food Drug and Cosmetic Act (abbreviated as FFDCA FDCA or FD&C is a set of laws passed by Congress in 1938 giving authority to the 
The SDWA requires EPA to establish National Primary Drinking Water Regulations (NPDWRs) for contaminants that may cause adverse public health effects.  The regulations include both mandatory levels (Maximum Contaminant Levels, or MCLs) and nonenforceable health goals (Maximum Contaminant Level Goals, or MCLGs) for each included contaminant. Maximum Contaminant Levels are standards that are set by the United States Environmental Protection Agency (EPA for Drinking water quality in MCLGs have extra significance because they can be used under the Superfund law as "Applicable or Relevant and Appropriate Requirements" (ARARs) in cleanups of contaminated sites on the National Priorities List (NPL). Superfund is the common name for the United States environmental policy officially known as the Comprehensive Environmental Response Compensation and Liability Act The National Priorities List ("NPL" is the list of hazardous waste sites in the United States eligible for long-term remedial action financed under the federal
The 1986 SDWA amendments  required EPA to apply future NPDWRs to both community and non-transient non-community water systems when it evaluated and revised current regulations. The first case in which this was applied was the final rule on July 8, 1987.  At that time NPDWRs were promulgated for certain synthetic volatile organic compounds (VOCs) and applied to non-transient non-community water systems as well as community water systems. In Chemistry, chemical synthesis is purposeful execution of Chemical reactions in order to get a product, or several products This article describes a highly specialized aspect of its subject in the "Terminology and legal definitions" section This rulemaking also clarified that non-transient non-community water systems were not subject to MCLs that were promulgated before July 8, 1987.
Future NPDWR standards will apply to non-transient non-community water systems because of concern for the long-term exposure of a stable population. It is important to note that EPA's decision to apply future NPDWRs to non-transient non-community water systems may have a significant impact on Department of Energy (DOE) facilities that operate their own drinking water systems. The United States Department of Energy ( DOE) is a Cabinet -level department of the United States government responsible for energy policy

The SDWA includes a whistleblower protection. This is an article about a term For the 2008 RTÉ drama see Whistleblower (TV series.  Employees in the US who believe they were fired or suffered another adverse action related to enforcement of this law have 30 days to file a written complaint with the Occupational Safety and Health Administration.

In 1996, Congress amended the Safe Drinking Water Act to emphasize sound science and risk-based standard setting, small water supply system flexibility and technical assistance, community-empowered source water assessment and protection, public right-to-know, and water system infrastructure assistance through a multi-billion-dollar state revolving loan fund. They were signed into law by President Bill Clinton on August 6, 1996. William Jefferson "Bill" Clinton (born William Jefferson Blythe III, August 19 1946 served as the forty-second President of the United States
