2014 DRINKING WATER QUALITY REPORT CITY OF LINTON, NORTH DAKOTA

We’re  very pleased to provide you with this year’s “Annual Drinking Water Quality Report.” We want to keep you informed about the excellent water and services we have delivered to you over the past year. Our goal is to provide you with a safe and dependable  supply of drinking water. Our water source is surface water from the Missouri River in Emmons County.

The  City  of  Linton  is involved  in North  Dakota’s   Wellhead  Protection  Program.  A copy  of  the  Wellhead Protection Plan along with other relevant information is available from our office during normal business hours. The ND Dept. of Health has prepared  a Source Water Assessment  for the City of Linton. Information  on this program is also available to the public dming normal business hours.

Our  public  water  system,  in cooperation  with  the North  Dakota  Department  of  Health,  has  completed  the delineation   and  contaminant/land   use  inventory  elements  of  the  North  Dakota  Source  Water  Protection Program.   Based  on  the  information   from  these  elements,  the  North  Dakota  Department  of  Health  has determined that our source water is “susceptible”  to potential contaminants.

If you have any questions  regarding  this report or concerning  your water utility, please contact  Robert Job at

701-254-4460.  We want our valued  customers  to be informed  about  their  water utility. If you want to learn more, please attend any of our regularly scheduled meetings. They are held on the first Monday of each month, September  through March at 6:00pm, and April through August at 5:00pm at Linton City Hall.  If attendance is desired, please call the office in advance, for further information.  If you are aware of non-English speaking individuals  who need help with the appropriate language translation,  please call the office at the number listed above.

The  City  of  Linton  would  appreciate  it  if large  volume  water  customers  would  please  post  copies  of  the “Annual  Drinking  Water  Quality  Report” in conspicuous  locations  or distribute  them to tenants,  residents, patients, students, and/or employees, so individuals who consume the water, but do not receive a water bill can learn about our water system.

The City of Linton routinely monitors for contaminants  in your drinking  water according to Federal and State laws. The following  table shows the results of our monitoring  for the period of January 1 51 to December 31st, 2014. As authorized and approved by the EPA, the State has reduced monitoring requirements for certain contaminants to less often than once per year because the concentrations of these contaminants are not expected to vary significantly from year to year. Some of the data [e.g. for inorganic contaminant], though representative, is more than one year old.

The sources  of drinking  water (both  tap 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 occmring  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:

 Microrobial 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 n·om urban storm water, industrial or domestic wastewater discharges, oil production, mining or farming.

Pesticides and herbicides, which come from a variety of sources such as agriculture, urban storm water 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, the Environmental Protection Agency (EPA) prescribes regulations  limit the amount of certain contaminants in water provided by public water systems.which 2014.

The Food and Drug Administration (FDA) regulations establish limits for contaminants in bottled water which must provide the same protection for public health.

In the following table you will find many terms and abbreviations you might not be familiar with. To help you better understand these terms we’ve provided the following definitions:

Not applicable (NA), No Detect (ND)

Parts per million (ppm) or Milligrams per liter (mg/1) -one  part per million corresponds to one minute in two years or a single penny in $10,000.

Parts per billion (ppb) or Micrograms per liter (f.l.!!/1) -one  part per billion corresponds to one minute in 2,000 years, or a single penny in $1 0,000,000.

Picocuries per/iter (pCi/1) -Pi co curies per liter is a measure of the radioactivity in water.

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 treatment technique is a required process intended to reduce the level of a contaminant in drinking water.

Maximum Contaminant Level-  The “Maximum Allowed” (MCL) is 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 - The “Goal” (MCLG) is 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 Disil fecttmt 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 Disil fectant Le1•el 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 contaminants.

*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. The City of Linton is responsible for providing high quality drinking water, but cannot control the  variety  of  materials  used  in  plumbing  components.  Use  water  from  the  cold  tap  for  drinking  and cooking.  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.

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 the 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 (1-800-426-4791).

Unregulated contaminants  are those for which EPA has not established  drinking water standards.  The purpose of  unregulated   contaminant   monitoring  is  to  assist  EPA  in  determining   the  occurrence   of  unregulated contaminants in drinking water and whether future regulation is warranted.

In  our  continuing  efTorts to  maintain  a  safe  and  dependable  water  supply  it  may  be  necessary  to  make improvements  in your water system. The costs of these improvements  may be reflected  in the rate structure. Rate adjustments may be necessary in order to address these improvements.

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  HIVIAIDS  or  other  immune  system  disorders,  some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinli:ing water from their health care providers.   EPA/CDC guidelines  on appropriate  means to lessen the risli: of infection  by cryptosporidium  and other microbiological  contaminants  are available from the Safe Drinking Water Hotline (l-800-426-4791).

The City of Linton works diligently to provide top quality water to every tap. We ask that all our customers help us protect our water sources, which are the heart of our community, our way of life and our children’s  future.
