Abbreviations
Definitions:The following tables contain scientific terms and measures,some of which may require explanation.
Maximum Contaminant Level Goal or(MCLG):The level of a contaminant in drinking water below which there is no known or expected health risk. MCLGs
allow for a margin of safety.
Maximum Contaminant Level or(MCL):The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as
feasible using the best available treatment technology.
Maximum Residual Disinfectant Level Goal(MRDLG):The level of a drinking water disinfectant below which there is no known or expected risk to health.
MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contamination.
Maximum Residual Disinfectant Level(MRDL):The highest level of disinfectant allowed in drinking water.There is convincing evidence that addition of a
disinfectant is necessary for control of microbial contaminants.
Action Level Goal(ALG):The level of a contaminant in drinking water below which there is no known or expected risk to health.ALGs allow for a margin of
safety.
Action Level(AL):The concentration of a contaminant which, if exceeded,triggers treatment or other requirements a water system must follow.
Avg: Regulatory compliance with some MCLs are based on running annual average of monthly samples.
MFL: Million Fibers per Liter(a measure of asbestos)
NTU: Nephelometric Turbidity Units(a measure of turbidity)
pCi/I: Piccocuries Per Liter,a measure of radioactivity
ppm: Parts Per Million or Milligrams Per Liter—or one ounce in 7,350 gallons of water
ppb: Parts Per Billion or Micrograms Per Liter—or one ounce in 7,350,000 gallons of water.
ppt: Parts per Trillion or Nanograms Per Liter(ng/L)
ppq: Parts per quadrillion,or picograms per liter(pg/L)
N/A: Not Applicable.
