Chlorine Residual 1-2018 Euless 0.7-4.0 0.5-4.0 4.0 Mg/I No The presence of a Chlorine Residual in drinking water indicates that
to a sufficient amount of chlorine was added initially to the water
Annual Average 12-2018 during treatment to inactivate the bacteria and some viruses;and
9 that the water is protected from recontamination during storage
2.14 before delivery.The presence of a Chlorine Residual in drinking
water is correlated with the absence of disease-causing organisms,
and thus is a measure of the quantity of water.
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.
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.
N/A: Not Applicable.
UG/L: Micrograms per liter.
Umhos/cm: Microsiemens per centimeter is a measurement for conductivity. It is expressed in either microSiemens(u5/cm)or
micromhos(umho/cm)which is the reciprocal of the unit of resistance,the ohm.
