We take great care to protect your water from several chemical contaminants and we add disinfectant to protect

you against microbial contaminants. The Safe Drinking Water Act (SDWA) requires states to develop a Source Water

Assessment (SWA) for each public water supply that treats and distributes raw source water in order to identify potential

contamination sources. The state has completed an assessment of our source water. For results of the source water

assessment, please contact us.

Message from EPA

Some people may be more vulnerable to contaminants in drinking water than the general population. Immunocompromised

persons, such as those with cancer undergoing chemotherapy, persons who have undergone organ transplants,

people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from

infections. These people should seek advice about drinking water from their health care providers. EPA/CDC guidelines on

appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from

the Safe Drinking Water Hotline (800-426-4791).

Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants.

The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants

and potential health effects can be obtained by calling the EPA’s Safe Drinking Water Hotline (800-426-4791).

The sources of drinking water (both tap water and bottled water) included rivers, lakes, streams, ponds, reservoirs,

springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally occurring

minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from

human activity.

Contaminants that may be present in source water before we treat it include:

Microbial contaminants, such as viruses and bacteria, may come from sewage treatment plants, septic systems, agricultural

livestock operations and wildlife.

Inorganic contaminants, such as salts and metals, can be naturally-occurring or result from urban storm water runoff,

industrial or domestic wastewater discharges, oil and gas production, mining or farming.

Pesticides and herbicides may come from a variety of sources such as storm water run-off, agriculture, and residential users.

Radioactive contaminants, can be naturally occurring or the result of mining activity

Organic contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and

petroleum production, may also come from gas stations, urban storm water run-off, and septic systems.

In order to ensure that tap water is safe to drink, EPA prescribes regulation which limits the amount of certain

contaminants in water provided by public water systems. We treat our water according to EPA’s regulations. Food and Drug

Administration regulations establish limits for contaminants in bottled water, which must provide the same protection for

public health.

Our water system tested a minimum of 5 samples per month in accordance with the Total Coliform Rule for

microbiological contaminants. Coliform bacteria are usually harmless, but their presences in water can be an indication

of disease-causing bacteria. When coliform bacteria are found, special follow-up tests are done to determine if harmful

bacteria are present in the water supply. If this limit is exceeded, the water supplier must notify the public by newspaper,

television or radio.

Water Quality Data

The tables following below list all of the drinking water contaminants that were detected during the 2019 calendar year.

The presence of these contaminants does not necessarily indicate that the water poses a health risk. Unless noted, the data

presented in this table is from testing done in 2019. The state requires us to monitor for certain contaminants less than once

per year because the concentrations of these contaminants are not expected to vary significantly from year to year. Some of

the data, though representative of the water quality, is more than one year old. The bottom line is that the water provided is safe.

Terms & Abbreviations

Maximum Contaminant Level Goal (MCLG): the “Goal” is the level of a contaminant in drinking water below which there is

no known or expected risk to human health. MCLG’s allow for a margin of safety.

Maximum Contaminant Level (MCL): the “Maximum Allowed” MCL is the highest level of a contaminant that is allowed

in drinking water. MCL’s are set as close to the MCLG’s as feasible using the best available treatment technology.

Action Level (AL): the concentration of a contaminant that, if exceeded, triggers treatment or other requirements that a

water system must follow.

Treatment Technique (TT): a treatment technique is a required process intended to reduce the level of a contaminant in

drinking water.

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. MRDLG’s do not reflect the benefits of the use of disinfectants to control microbial

contaminants.

Non-Detects (ND): laboratory analysis indicates that the constituent is not present.

Parts per Million (ppm) or milligrams per liter (mg/l)

Parts per Billion (ppb) or micrograms per liter (μg/l)

Picocuries per Liter (pCi/L): picocuries per liter is a measure of the radioactivity in water.

Millirems per Year (mrem/yr): measure of radiation absorbed by the body.

Million Fibers per Liter (MFL): million fibers per liter is a measure of the presence of asbestos fibers that are longer than 10

micrometers.

Nephelometric Turbidity Unit (NTU): nephelometric turbidity unit is a measure of the clarity of water. Turbidity in excess of

5 NTU is just noticeable to the average person.

Health Information Regarding Water Quality

While your drinking water meets EPA’s standard for arsenic, it does contain low levels of arsenic. EPA’s standard

balances the current understanding of arsenic’s possible health effects against the costs of removing arsenic from drinking

water. EPA continues to research the health effects of low levels of arsenic which is a mineral known to cause cancer in

humans at high concentrations and is linked to other health effects such as skin damage and circulatory problems.

While your water meets the EPA’s standard for Lead, if present at elevated levels this contaminant can cause serious

health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials

and components associated with service lines and home plumbing. Your Water System is responsible for providing high

quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been

sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes

before using water for drinking or cooking. If you are concerned about lead in your drinking water, you may wish to have

your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is

available from the Safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead.

Violations

During the 2020 calendar year, TOWN OF MINDEN is required to include an explanation of the violation(s) in the

table below and the steps taken to resolve the violation(s) with this report.

Type Category Analyte Compliance Period

No Violations Occurred in the Calendar Year of 2020.

(A) Coliforms are bacteria that are naturally present in the environment and are used as an indicator that other,

potentially harmful, waterborne pathogens may be present or that a potential pathway exists through which

contamination may enter the drinking water distribution system. We found coliforms indicating the need to look for

potential problems in water treatment or distribution. When this occurs, we are required to conduct an assessment(s) to

identify problems and to correct any problems that were found during these assessments.

(B) During the past year we were required to conduct one (1) Level 1 assessment. (1) Level 1 assessment was

completed. In addition, we were required to take (1) corrective action and (1) corrective action was completed. The

event was isolated to the Amber Way tank, and no water containing the bacteria was detected in the Towns system.

The positive result was determined to have been caused by a sampling error.
