Water quality laws govern the protection of water resources for human health and the environment. Water quality laws are legal standards or requirements governing water quality, that is, the concentrations of water pollutants in some regulated volume of water. Such standards are generally expressed as levels of a specific water pollutants ...
The SDWA authorized the EPA to promulgate regulations regarding water supply. The major regulations are in Title 40 of the Code of Federal Regulations: 40 CFR Parts 141, 142, and 143. Parts 141, 142, and 143 regulate primary contaminants, implementation by states, and secondary contaminants. Primary contaminants are those with health impacts.
The National Water Quality Inventory Report to Congress is a general report on water quality, providing overall information about the number of miles of streams and rivers and their aggregate condition. [65] The CWA requires states to adopt standards for each of the possible designated uses that they assign to their waters.
These regulations can include emission limits that specify the rate, amount, and kinds of pollutants that may be emitted from a given source over a specific period. The EPA's various effluent limitations for water pollution under the CWA are simply a few of the many environmental regulations that are nominally performance standards.
Therefore, the term soil health can only be understood within the context of the user of the term, and their aspirations of a soil, as well as by the boundary definition of the soil at issue. Finally, intrinsic to the discussion on soil health are many potentially conflicting interpretations, especially ecological landscape assessment vs ...
Water quality objectives are set and periodically revised by regulatory agencies, such as the Environmental Protection Agency (EPA), to define the limits of water quality for different uses, which include human health, but also other ecologically important functions, wildlife habitat, irrigated agriculture, etc. For example, if the irrigation ...
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.
Maximum contaminant levels (MCLs) are standards that are set by the United States Environmental Protection Agency (EPA) for drinking water quality. [ 1 ] [ 2 ] An MCL is the legal threshold limit on the amount of a substance that is allowed in public water systems under the Safe Drinking Water Act (SDWA).
