Is my water safe?
We are pleased to present this year's Annual Water Quality Report (Consumer Confidence Report) as required by the Safe Drinking Water Act (SDWA). This report is designed to provide details about where your water comes from, what it contains, and how it compares to standards set by regulatory agencies. This report is a snapshot of last year's water quality. We are committed to providing you with information because informed customers are our best allies.
Water Quality Data Table
In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of contaminants in water provided by public water systems. The table below lists all of the drinking water contaminants that we detected during the calendar year of this report. Although many more contaminants were tested, only those substances listed below were found in your water. All sources of drinking water contain some naturally occurring contaminants, At low levels, these substances are generally not harmful in our drinking water. Removing all contaminants would be extremely expensive, and in most cases, would not provide increased protection of public health. A few naturally occurring minerals may actually improve the taste of drinking water and have nutritional value at low levels. Unless otherwise noted, the data presented in this table is from testing done in the calendar year of the report. The EPA or the State requires us to monitor for certain contaminants less than once per year because the concentrations of these contaminants do not vary significantly from year to year, or the system is not considered vulnerable to this type of contamination. As such, some of our data, though representative, may be more than one year old. In this table you will find terms and abbreviations that might not be familiar to you. To help you better understand these terms, we have provided the definitions below the table.
MRDL Your Water Range Sample Date Violation Typical Source
Disinfectants & Dis'nfection By-Products
(There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants)
Haloacetic Acids (HAAS) (ppb) NA 60 33 NA 33 2015 No By-product of drinking water chlorination
TTHMs [Total Trihalomethanes] (ppb) NA 80 55 NA 55 2015 No By-product of drinking water disinfection
Total Coliform (positive samples/month) 0 1 1 NA 2015 No In July of 2015 we had a sampling error. In the next month within 24 hours we performed 5 additional test upstream and downstream from our sampling site and we tested additional sites. All test came back negative. Naturally present in the environment.
Contaminants MCLG AL Your Water Sample Date P Samples
AL Exceeds AL Typical Source
Copper - action level at consumer taps (ppm) 1.3 1.3 .0418 2015 0 No Corrosion of household plumbing systems; Erosion of natural deposits
In an effort to insure the safest water possible the State has required us to monitor some contaminants not required by Federal regulations. Of those contaminants only the ones listed below were found in your water.
Water Violation Explanation and Comment
Chlorine 4 ppm 2,2 ppm No Water additive used to control microbes.
Lead 15 ppb 0 ppb No The results were less than 5.00 ppb. Low detection limit In the month of June we sampled 20 residents. This is an excellent result.
ppm ppm: parts per million, or milligrams per liter (ng/L)
ppb ppb: parts per billion, or micrograms per liter (gg/L)
positive samples/month positive samples/month: Number of samples taken monthly that were found to be positive
NA NA; not applicable
ND ND: Not detected
NR NR: Monitoring not required, but recommended.
important Drinking Water Definitions
MCLG MCLG: Maximum Contaminant Level Goal; 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 MCL: Maximum Contaminant Level: 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.
TT TT: Treatment Technique: A required process intended to reduce the level of a contaminant in drinking water,
AL AL: Action Level: The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
Exemptions Variances and Exemptions: State or EPA permission not to meet an MCL or a treatment technique under certain conditions.
MRDLG MRDLG: Maximum residual disinfection level goal. 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.
MRDL MRDL: Maximum residual disinfectant level. 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.
MNR MNR: Monitored Not Regulated
MPL MPL: State Assigned Maximum Permissible Level
