Safe Drinking Water Act Amendments of 1986,
The Safe Drinking Water Act (SDWA) is the principal federal law in the United States intended to ensure safe drinking water for the public. 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.
SDWA applies to every public water system (PWS) in the United States. There are currently more than 150,000 public water systems providing water to almost all Americans at some time in their lives. The Act does not cover private wells.

National Primary Drinking Water Regulations
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. MCLs have additional significance because they can be used under the Superfund law as "Applicable or Relevant and Appropriate Requirements" in cleanups of contaminated sites on the National Priorities List.
Federal drinking water standards are organized into six groups:
- Disinfection Byproducts
- Inorganic Chemicals
- Organic Chemicals
EPA has issued standards for Cryptosporidium, Giardia lamblia, Legionella, coliform bacteria and enteric viruses. EPA also requires two microorganism-related tests to indicate water quality: plate count and turbidity.
"Lead Free" plumbing requirements
The 1986 amendments require EPA to set standards limiting the concentration of lead in public water systems, and defines "lead free" pipes as:
- (1) solders and flux containing not more than 0.2 percent lead;
- (2) pipes and pipe fittings containing not more than 8.0 percent lead; and
- (3) plumbing fittings and fixtures as defined in industry-developed voluntary standards (issued no later than August 6, 1997), or standards developed by EPA in lieu of voluntary standards.
Non-community water systems
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 facilities that operate their own drinking water systems.
The SDWA requires EPA to identify and list unregulated contaminants which may require regulation. The Agency must periodically publish this list, called the "Contaminant Candidate List" and decide whether to regulate at least five or more listed contaminants. EPA uses this list to prioritize research and data collection efforts, which support the regulatory determination process.
Monitoring, compliance and enforcement
Public water systems are required to regularly monitor their water for contaminants. Water samples must be analyzed using EPA-approved testing methods, by laboratories that are certified by EPA or a state agency.
Community water systems—those systems that serve the same people throughout the year—must provide an annual "Consumer Confidence Report" to customers. The report identifies contaminants, if any, in the drinking water and explains the potential health impacts.
Oversight of public water systems is managed by "primacy" agencies, which are either state government agencies or EPA regional offices. All state and territories, except Wyoming and the District of Columbia, have received primacy approval from EPA, to supervise the PWS in their respective jurisdictions. A PWS is required to submit periodic monitoring reports to its primacy agency. Violations of SDWA requirements are enforced initially through a primacy agency's notification to the PWS, and if necessary following up with formal orders and fines.
Airline water supplies
In 2004, EPA tested drinking water quality on commercial aircraft and found that 15 percent of tested aircraft water systems tested positive for total coliform bacteria. EPA published a final regulation for aircraft public water systems in 2009. The regulation requires air carriers operating in the U.S. to conduct coliform sampling, management practices, corrective action, public notification, operator training, and reporting and recordkeeping. An airline with a non-complying aircraft must restrict public access to the on-board water system for a specified period.
Underground Injection Control (UIC) Program
The 1974 act authorized EPA to regulate injection wells in order to protect underground sources of drinking water. Congress amended the SDWA in 2005 to exclude hydraulic fracturing, an industrial process for recovering oil and natural gas, from coverage under the UIC program. This exclusion has been called the "Halliburton Loophole". Halliburton is the world's largest provider of hydraulic fracturing services.
The Fracturing Responsibility and Awareness of Chemicals Act (H.R. 2766, S. 1215) would have repealed the exemption for hydraulic fracturing in the SDWA and regulated the oil and natural gas recovery process under the UIC program. The bill was introduced in the 111th Congress (2009) and did not pass. See "Proposed amendments" below for details.
The SDWA includes a whistleblower protection provision. 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.
Prior to the SDWA there were few national enforceable requirements for drinking water. Improvements in testing were allowing the detection of smaller concentrations of contaminant and allowing more tests to be run. Many states had drinking water regulations prior to adoption of the federal SDWA.
The Safe Drinking Water Act was one of several pieces of environmental legislation in the 1970s. Discovery of organic contamination in public drinking water and the lack of enforceable, national standards persuaded Congress to take action.
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 "Phase I" final rule, published on July 8, 1987. At that time NPDWRs were promulgated for certain synthetic volatile organic compounds and applied to non-transient non-community water systems as well as community water systems. This rulemaking also clarified that non-transient non-community water systems were not subject to MCLs that were promulgated before July 8, 1987. The 1986 amendments were signed into law by President Ronald Reagan on June 19, 1986.
In addition to requiring more contaminants to be regulated, the 1986 amendments included:
- Well head protection
- New monitoring for certain substances
- Filtration for certain surface water systems
- Disinfection for certain groundwater systems
- Restriction on lead in solder and plumbing
- More enforcement powers.
1996 SDWA amendments
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. The amendments were signed into law by President Bill Clinton on August 6, 1996.
Main points of the 1996 amendments
- Consumer Confidence Reports: All community water systems must prepare and distribute annual reports about the water they provide, including information on detected contaminants, possible health effects, and the water's source.
- Cost-Benefit Analysis: EPA must conduct a thorough cost-benefit analysis for every new standard to determine whether the benefits of a drinking water standard justify the costs.
- Drinking Water State Revolving Fund. States can use this fund to help water systems make infrastructure or management improvements or to help systems assess and protect their source water.
- Microbial Contaminants and Disinfection Byproducts: EPA is required to strengthen protection for microbial contaminants, including cryptosporidium, while strengthening control over the byproducts of chemical disinfection. EPA promulgated the Stage 1 Disinfectants and Disinfection Byproducts Rule and the Interim Enhanced Surface Water Treatment Rule to address these risks.
- Operator Certification: Water system operators must be certified to ensure that systems are operated safely. EPA issued guidelines in 1999 specifying minimum standards for the certification and recertification of the operators of community and non-transient, noncommunity water systems. These guidelines apply to state operator certification programs. All states are currently implementing EPA-approved operator certification programs.
- Public Information and Consultation: SDWA emphasizes that consumers have a right to know what is in their drinking water, where it comes from, how it is treated, and how to help protect it. EPA distributes public information materials (through its Drinking Water Hotline, Safewater web site, and Resource Center) and holds public meetings, working with states, tribes, water systems, and environmental and civic groups, to encourage public involvement.
- Small Water Systems: Small water systems are given special consideration and resources under SDWA, to make sure they have the managerial, financial, and technical ability to comply with drinking water standards.
Through the Energy Policy Act of 2005, the Safe Drinking Water Act was amended to exclude the underground injection of any fluids or propping agents other than diesel fuels used in hydraulic fracturing operations from being considered as "underground injections" for the purposes of the law.

Controversy surrounds the practice of hydraulic fracturing as a threat to drinking water supplies. The Fracturing Responsibility and Awareness of Chemicals Act, dubbed the "FRAC Act," was introduced to both houses of the 111th Congress on June 9, 2009. The bill would have repealed the exemption for hydraulic fracturing in the SDWA and regulated the oil and natural gas recovery process under the UIC program. It would have required the energy industry to disclose the chemicals it mixes with the water and sand it pumps underground in the process (also known as "fracking"), information that has largely been protected as proprietary or trade secrets. Without knowing the identity of the proprietary components, regulators cannot test for their presence. This prevents government regulators from establishing baseline levels of the substances prior to hydraulic fracturing and documenting changes in these levels, thereby making it impossible to determine whether hydraulic fracturing is contaminating the environment with these substances. The natural gas industry opposed the legislation. The House bill was introduced by representatives Diana DeGette (D-CO), Maurice Hinchey (D-NY), and Jared Polis (D-CO). The Senate version was introduced by senators Bob Casey (D-PA), and Chuck Schumer (D-NY). After a delay, the FRAC Act was re-introduced in both houses of the 112th United States Congress. In the Senate, Sen. Bob Casey (D-PA) introduced S. 587 on March 15, 2011. In the House, Rep. Diana DeGette (D-CO) introduced H.R. 1084 on March 24, 2011.
