To set a maximum contaminant level for a contaminant, EPA first determines how much of the contaminant may be present with no adverse health effects. This level is called the maximum contaminant level goal (MCLG). MCLGs are non-enforceable public health goals. The legally enforced MCL is then set as close as possible to the MCLG.
In 1991, as part of the SDWA, the EPA placed chromium under its list of maximum contaminant level goals (MCLG), to have a maximum contaminant level (MCL) of 100 ppb. [45] In 1996, the SDWA was amended to include a provision known as the Unregulated Contaminant Monitoring Rule (UCMR). [46]
It can also increase the risk of bone fractures. The report concluded unanimously that the present maximum contaminant level goal of 4 mg/L for fluoride should be lowered. [45] Several states have more stringent regulations. For example, the fluoride MCL for public water systems in New York (state) is 2.2 mg/L. [46]
When the EPA team asked for an operation and maintenance manual for the system, or for a list of standard operating procedures (or SOPs ), the Navy provided 15 individual SOPs. The report said ...
The United States Environmental Protection Agency (EPA) classifies the herbicide as toxicity class III - slightly toxic. [6] The Maximum Contaminant Level Goal (MCLG) for Alachlor is zero, to prevent long-term effects. The Maximum Contaminant Level (MCL) for drinking water is two parts per billion (2 ppb). [8]
EPA illustration of lead sources in residential buildings Infographic about lead in drinking water. The Lead and Copper Rule (LCR) is a United States federal regulation that limits the concentration of lead and copper allowed in public drinking water at the consumer's tap, as well as limiting the permissible amount of pipe corrosion occurring due to the water itself.

The National Emission Standards for Hazardous Air Pollutants (NESHAP) are air pollution standards issued by the United States Environmental Protection Agency (EPA). The standards, authorized by the Clean Air Act, are for pollutants not covered by the National Ambient Air Quality Standards (NAAQS) that may cause an increase in fatalities or in serious, irreversible, or incapacitating illness.
The Safe Drinking Water Act (SDWA) is the primary federal law in the United States intended to ensure safe drinking water for the public. [3] 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 that implement the standards.
