|Water Quality Data Table|
MCLG: Maximum Contaminant Level Goal, or the level of a contaminant in
drinking water below which there is no known or expected risk to health.
MCLGs allow for a margin of safety. - MCL: Maximum Contaminant Level, or
the highest level of contaminant that is allowed in drinking water. MCLs
are set as close to the MCLGs as feasible using the best available
treatment technology. - AL: Action Level, or the concentration of a
contaminant which, if exceeded, triggers treatment or other requirements
which a water system must follow. - TT: Treatment Technique, or a
required process intended to reduce the level of a contaminant in
-"<": a symbol which means less than. A result of <5 means that the lowest level that could be detected was 5, and the contaminant in that sample was not detected. - NA: Not Applicable or no standard set.
Abbreviations: ppm: Parts per Million or Milligrams per Liter (mg/L) are units of measure for concentration of a contaminant. A part per million corresponds to one second in a little over 11.5 days. - ppb: Parts per Billion or Micrograms per Liter (µg/L) are units of measure for concentration of a contaminant. A part per billion corresponds to one second in 31.7 years.
