The maximum permissible level of a contaminant in water in a public water system. The MCL is established by the Environmental Protection Agency (EPA). MCLs are defined in the Safe Drinking Water Act as the level that may be achieved with the use of the best available technology, treatment techniques, and other means that EPA finds are available after taking cost in consideration. See also treatment technique.
The highest level of a contaminant that EPA allows in drinking water. MCLs ensure that drinking water does not pose either a short-term or long-term health risk. EPA sets MCLs at levels that are economically and technologically feasible. Some states set MCLs which are more strict than EPA's.
The highest (maximum) level of a contaminant allowed to go uncorrected by a public water system under federal or state regulations. Depending on the contaminant, allowable levels might be calculated as an average over time, or might be based on individual test results. Corrective steps are implemented if the MCL is exceeded.
A contaminant concentration in drinking water that U.S. Environmental Protection Agency (USEPA) deems protective of public health (considering the availability and economics of water treatment technology) over a lifetime (70 years) at an exposure rate of 2 liters of water per day.
The maximum allowable concentration of a drinking water contaminant as legislated through the Safe Drinking Water Act.
enforceable drinking water standards that are protective of public health to the extent feasible.
(MCL) The maximum allowable concentration of a given constituent in potable water.
The legal limit set by the U.S. Environmental Protection Agency and each individual state for the maximum amount of a chemical that is allowed to be in the public water supply. Each state can create stricter levels of control, but cannot lower the levels of control set by the EPA.
A drinking water standard which is set by the EPA. The MCL is the maximum amount of a compound that can be present in drinking water at any given time.
The maximum allowable concentration of a contaminant in water as established in the U.S. EPA Drinking Water Regulations.
Primary drinking water standard for public water supplies established by the U.S. Environmental Protection Agency (2001). MCLs are health related and legally enforceable.
The highest level of a contaminant permissible in water in a public water system.
A contaminant level for drinking water, established by the California Department of Health Services, Division of Drinking Water and Environmental Management, or by the U.S. Environmental Protection Agency. These levels are legally-enforceable standards based on health risk (primary standards) or non-health concerns such as odor or taste (secondary standards).
(MCL) the highest concentration of a substance permissible in public drinking water supply as determined by the EPA (Environmental Protection Agency)
is the highest level of a contaminant allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology. Most often, MCLs are defined in parts per million or parts per billion. One part per million equals: - One inch in 16 miles - One minute in two years - One cent in $10,000
The highest level of a contaminant that is allowed in drinking water as delineated by the National Primary Drinking Water Regulations. These levels are based on consideration of health risks, technical feasibility of treatment, and cost-benefit analysis.
The highest concentration of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLG as feasible using the best available treatment technology and taking cost into consideration.
The maximum permissible level of a contaminant in water which is delivered to the free flowing outlet of the ultimate user of a public water system, except in the case of turbidity where the maximum permissible level is measured at the point of entry to the distribution system. Contaminants added to the water under circumstances controlled by the user are excluded from this definition, except those contaminants resulting from the corrosion of piping and plumbing caused by water quality.
Compare? The maximum level of certain contaminants permitted in drinking water supplied by a public water system as set by EPA under the federal Safe Drinking Water Act.
(MCL), a limit on the concentration of a chemical in drinking water which will protect the public health.
the maximum permissible level of a contaminant in water which is delivered to any user of a public water system. [Source: 40 CFR Part 141.2
the maximum level of a contaminant to allowed in water by federal law. This level is based on health effects as well as currently available treatment methods.
The maximum level of contaminant discharge without violating regulatory standards, usually mandated by state requirements and referencing maximum levels of toxins in drinking water.
The MCL is the drinking water standard established by EPA. It is the maximum permissible level of a contaminant in water that is delivered to the free-flowing outlet. MCLs are considered protective of public health over a lifetime (70 years) for people consuming two liters of water per day.
The MCL is the maximum amount of a regulated contaminant allowable in drinking water. The USEPA sets standards for drinking water that all water providers must meet. Tucson Water routinely monitors the drinking water we deliver for each regulated contaminant and for many other substances of interest to our customers.
the maximum concentration of specific contaminants that is allowed under the National Standards. Generally expressed in terms of the maximum amount of contaminant allowed in a given amount of water using units of mg/l or ppm (parts per million).
The MCL is a regulatory limit set by the Environmental Protection Agency (EPA) for contaminants in drinking water. If an MCL is exceeded, regulatory action is required under the Safe Drinking Water Act. MCLs are not always strictly health based but can consider technological or economic feasibility.
Enforceable standards for public drinking water supplies under the Safe Drinking Water Act. Also referred to as drinking water standards.
The highest level of a contaminant that EPA allows in drinking water. MCLs are set as close to Maximum Contaminant Level Goals (MCLGs) as feasible using the best available treatment technology and taking cost into consideration. MCLs are enforceable standards.
the highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as possible.
the designation given by the U.S. Environmental Protection Agency (EPA) to water-quality standards promulgated under the Safe Drinking Water Act. The MCL is the greatest amount of a contaminant that can be present in drinking water without causing a risk to human health.
Under the Safe Drinking Water Act (USA), primary MCL is a regulatory concentration for drinking water which takes into account both adverse effects (including sensitive populations) and technological feasibility (including natural background levels): secondary MCL is a regulatory concentration based on "welfare", such as taste and staining, rather than health, but also takes into account technical feasibility. MCL Goals (MCLG) under the Safe Drinking Water Act do not consider feasibility and are zero for all human and animal carcinogens
A standard for drinking water established by USEPA under the Safe Drinking Water Act which is the maximum permissible level of a contaminant in water which is delivered to any user of a public water supply.
A standard that is the highest allowable concentration of a contaminant in drinking water. This standard is set as a result of scientific studies of contaminant effects on health or aesthetics.
(MCL)--Maximum level of a contaminant allowed in water by Federal law. Based on health effects and currently available treatment methods.
Highest level of a contaminant allowed in drinking water. MCLs are set as close to the Maximum Contaminant Level Goal as feasible using the best available treatment technology.
(Usually abbreviated MCL.) A federal drinking water standard that specifies the maximum concentration level for a regulated chemical in drinking water.
The maximum permissible level of a contaminant in water delivered to any user of a public system. MCLs are enforceable standards.
Maximum Contaminant Levels are standards that are set by the United States Environmental Protection Agency (EPA) for drinking water quality. A Maximum Contaminant Level (MCL) is the legal threshold limit on the amount of a hazardous substance that is allowed in drinking water under the Safe Drinking Water Act. The limit is usually expressed as a concentration in milligrams or micrograms per liter of water.
