2017 Consumer Confidence Report

Lower Bartlett Water Precinct

0161020

 

Introduction

Like any responsible public water system, our mission is to deliver the best quality drinking water and provide reliable service at the lowest appropriate cost.

Aging infrastructure presents challenges to drinking water safety, and continuous improvement is needed to maintain the quality of life we desire for today and for the future.

In the past year, we have continued with Capital Improvements previously identified in our Master Plan which serves as a planning and decision tool for current and future Commissioners, customers, and voters. The Master Plan furthers the mission of the Lower Bartlett Water Precinct to provide clean and reliable drinking water at an affordable cost, with the goal of sustaining human life and fostering economic growth within the Lower Bartlett Water Precinct’s service area.   We continue with significant improvement to Water Loss directly attributable to a Water Loss Control Program which has focused on Non-Revenue Water and Apparent and Real Losses from leakage, metering inaccuracies, and unbilled/unmetered consumption. These investpsa_waterglass_examplements along with on-going operation and maintenance costs are supported by Water Rates, Annual Charges, and Taxation. When considering the high value we place on water, it is truly a bargain to have water service that protects public health, fights fires, supports business, the economy, and provides us with the high-quality of life we enjoy. In 2017 we are looking at service area expansion on Rte. 302 westerly towards Rolling Ridge/ Bartlett Village Water Precinct and are conducting a feasibility study for Wastewater Collection in response to a Well Field Nitrate Contamination Vulnerability Assessment completed in February 2017.

 

What is a Consumer Confidence Report?

The Consumer Confidence Report (CCR) details the quality of your drinking water, where it comes from, and where you can get more information. This annual report documents all detected primary and secondary drinking water parameters, and compares them to their respective standards known as Maximum Contaminant Levels (MCLs).

 

The sources of drinking water (both tap water and bottled water) include 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 include:

Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.

Inorganic contaminants, such as salts and metals, which 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, which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses.

Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also come from gas stations, urban storm water runoff, and septic systems.

Radioactive contaminants, which can be naturally-occurring or be the result of oil and gas production and mining activities.

In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems.  The US Food and Drug Administration (FDA) regulations establish limits for contaminants in bottled water which must provide the same protection for public health.

What is the source of my drinking water?

The Lower Bartlett Water Precinct obtains its water from two gravel packed (overburden) wells located Westerly of the Rte. 16 corridor and about 1500 feet Easterly of the Saco River. Both wells have a capacity of 750 gallons per minute (1,080,000 gallons per day) for a combined safe yield of 2,160,000 gallons per day. Water is treated for pH/corrosion control (sodium hydroxide) and disinfection (sodium hypochlorite).

Why are contaminants in my water? 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 Environmental Protection Agency’s Safe Drinking Water Hotline at 1-800-426-4791.

Do I need to take special precautions? Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons 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 at 1-800-426-4791.

Source Water Assessment Summary:

 

DES prepared drinking water source assessment reports for all public water systems between 2000 and 2003 in an effort to assess the vulnerability of each of the state’s public water supply sources. Included in the report is a map of each source water protection area, a list of potential and known contamination sources, and a summary of available protection options.  The results of the assessment, prepared on April 12, 2002 are noted below. 

  GPW 1, 1susceptibility factors were rated high, 1 were rated medium, and 10 were rated low.

  GPW 2, 2 susceptibility factors were rated high, 1 were rated medium, and 9 were rated low.

Note:  This information is over 14 years old and includes information that was current at the time the report was completed.  Therefore, some of the ratings might be different if updated to reflect current information.  At the present time, DES has no plans to update this data.

The complete Assessment Report is available for review at the Lower Bartlett Water Precinct office located at 34 Route 302 Glen, NH  For more information, call the Precinct office @356-6738 or visit the DES Drinking Water Source Assessment website at http://des.nh.gov/organization/divisions/water/dwgb/dwspp/dwsap.htm.

Definitions

Ambient Groundwater Quality Standard or AGQS: The maximum concentration levels for contaminants in groundwater that are established under RSA 485-C, the Groundwater Protection Act.

Action Level or AL: The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.

Level I Assessment: A study of the water system to identify potential problems and determine, if possible, why total coliform bacteria have been found in our water system.

Level II Assessment: A very detailed study of the water system to identify potential problems and determine, if possible, why an E.coli MCL violation has occurred and/or why total coliform bacteria have been found in our water system on multiple occasions.

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 Contaminant Level Goal or MCLG: 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.

Maximum Residual Disinfectant Level or 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 or 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 contaminants.

Treatment Technique or TT: A required process intended to reduce the level of a contaminant in drinking water.

If Lead is present the following statement must be included.

Drinking Water Contaminants:

Lead: If present, elevated levels of lead 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.  This water system is responsible for high quality drinking water, but can not control the variety of materials used in your plumbing components.  When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing cold water from your tap for at least 30 seconds before using water for drinking or cooking.  Do not use hot water for drinking and cooking.  If you are concerned about lead in your 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://water.epa.gov/drink/info/lead/index.cfm

Corrosion of household plumbing systems, erosion of natural deposits

(15 ppb in more than 5%) Infants and young children are typically more vulnerable to lead in drinking water than the general population. It is possible that lead levels at your home may be higher than at other homes in the community as a result of materials used in your home’s plumbing. If you are concerned about elevated lead levels in your home’s water, you may wish to have your water tested and flush your tap for 30 seconds to 2 minutes before using tap water. Additional information is available from the Safe Drinking Water Hotline (800-426-4791).

(above 15 ppb) Infants and children who drink water containing lead in excess of the action level could experience delays in their physical or mental development. Children could show slight deficits in attention span and learning abilities. Adults who drink this water over many years could develop kidney problems or high blood pressure.
