What Do The Following Tables Mean?
The tables in this report show the results of our water-quality analyses for January 1 to December 31, 2016. Every regulated contaminant that we detected in the water, even in the most minute traces, is listed here. The table contains the name of each substance, the highest level allowed by regulation (MCL), the ideal goals for public health, the amount detected, the usual sources of such contamination, footnotes explaining our findings, and a key to units of measurement. The State allows us to monitor for some contaminants less than once per year because the concentrations of these contaminants do not change frequently. Some of our data, though representative, are more than one year old. Although we ran many tests, only the listed substances were found. They are all below the MCL required. We are pleased to report that your drinking water meets or exceeds all Federal and State requirements. The following definitions are important:
Maximum Contaminant Level (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 Contaminant Level Goal (MCLG): The level of contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.
Maximum Residual Disinfectant Level (MRDL): The highest level of a 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 microbes.
Action Level (AL): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
Treatment Technique (TT): A required process intended to reduce the level of a contaminant in drinking water.
Key To Contaminant Lists
| NTU = | Nephelometric Turbidity Units (measure of water clarity) | N/A = | Not Applicable |
| ppb = | parts per billion, or micrograms per liter (µg/l) | ppm = | part per million, or milligrams per liter (mg/l) |
| MinRDL= | minimum level of residual disinfectant required at the entry point to the distribution system |
