Definitions and Abbreviations: The following table contains scientific terms and measures, some may require explanation.
ppm- parts per million or milligrams per liter (mg/l). One ounce in 7,350,000 gallons of water
ppb- parts per billion or micrograms per liter (ug/l). One ounce in 7,350,000 gallons of water
Maximum Contaminant Level (MCL)- The highest level of substance that is allowed in drinking water. MCLs are set as close to
the MCLGs as feasible using best available treatment technology.
Maximum Contaminant Level Goal (MCLG)- The level of a substance in drinking water below which there is no known or
expected health risk. MCLGs allow a margin for safety
Treatment Technique (TT)- A required process intended to reduce the level of a substance in drinking water
MFL- million fibers per liter (a measure of asbestos)
NTU- Nephelometric turbidity units. Unit of a measure of the turbidity (cloudiness) of water
pCi/L- picocuries per liter (a measure of radioactivity)
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
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 contaminants.
Action Level (AL)- The concentration of a substance, which, if exceeded, triggers treatment or other requirements which a
water system must follow.
Naturally occurring mineral salts
Total dissolved mineral constitute in water
Naturally occurring calcium
J- Analyte detected below the quantitation limit but above the detection limit
ND- Analyte not detected in sample
N/A- not applicable
