Annual Drinking Water Quality Report January-December 2015

Town of Loxley

The Town of Loxley is pleased to present to you this year’s Annual Quality Water Report. This report is designed to inform you about the quality water and services we deliver to you every day. Our constant goal is to provide you with a safe and dependable supply of drinking water. We want you to understand the efforts we make to continually improve the water treatment process and protect our water resources. We are committed to ensuring the quality of your water.  Our four well sources are from the Mioncere Aquifer.  Well #1 is located on North Holly Street, Well #2 located on County Road 55, Well #3 located on US Hwy 90 West and Well #4 located on located on US Hwy 90 West.  We add chlorine to the water to kill bacteria, lime to produce a desirable water quality by raising the pH level to reduce corrosion and acidic conditions.  Fluoride is added to help in the reduction of cavities in the teeth.

 

We have a Source Water Protection Plan available from our office that provides more information such as potential sources of contamination. A map of the possible contaminate sites is available for viewing at the town hall. I’m pleased to report our drinking water is safe and meets federal and state requirements. If you have questions about this report or concerning your water utility, please contact Richard Ridder II, Loxley Town Hall at 251-964-5162We want our valued customers to be informed about their water utility. If you want to learn more, please attend our regularly scheduled meetings held on the second Monday of each month, 6 PM, Loxley Town Hall, located at 1089 South Hickory Street.

The Town of Loxley routinely monitors for contaminants in your drinking water according to Federal and State laws.  This  table  shows  the  results  of  our  monitoring  for the period of January 1st to December 31st, 2015All drinking water, including bottled drinking water, may be reasonably expected to contain at least small amounts of some contaminants.   It’s important to remember that the presence of these contaminants does not necessarily pose a health risk.

 

PLAIN LANGUAGE DEFINITION

  • Not Required (NR) – Laboratory analysis not required due to waiver granted by the Environmental Protection Agency for the State of Alabama.
  • Parts per million (ppm) or Milligrams per liter (mg/l) – 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 – one part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000.
  • Parts per trillion (ppt) or Nanograms per liter (nanograms/l) – one part per trillion corresponds to one minute in 2,000,000 years, or a single penny in $10,000,000,000.
  • Parts per quadrillion (ppq) or Picograms per liter (picograms/l) – one part per quadrillion corresponds to one minute in 2,000,000,000 years or one penny in $10,000,000,000,000.
  • 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.
  • 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.
  • Variances & Exemptions (V&E) – State or EPA permission not to meet an MCL or a treatment technique under certain conditions.
  • 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) – (mandatory language) A treatment technique is a required process intended to reduce the level of a contaminant in drinking water.
  • Threshold Odor Number (T.O.N.)- The greatest dilution of a sample with odor-free water that still yields a just-detectable odor.
  • Maximum Contaminant Level – (mandatory language) 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 – (mandatory language) 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 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.
  • 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.
  • Not Detected- (ND) Levels below method detection limits

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 run-off, 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, storm water run-off, 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 run-off, and septic systems.
  • Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and mining activities.

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.

 

GENERAL INFORMATION

As you can see by the tables, our system had no violations of allowable limits of contaminants in drinking water. We’re proud that your drinking water meets or exceeds all Federal and State requirements. We have learned through our monitoring and testing that some contaminants have been detected. The EPA has determined that your water IS SAFE at these levels.  MCL’s are set at very stringent levels. To understand the possible health effects described for many regulated constituents, a person would have to drink two liters of water every day at the MCL level for a lifetime to have a one-in-a-million chance of having the described health effect.

 

 

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.

 

Some  people  may  be  more vulnerable  to  contaminants  in  drinking  water  than  the   general   population.   People   who  are  immuno-compromised,   such   as   cancer   patients   undergoing  chemotherapy, organ transplant recipients, HIV/AIDS positive or individuals with  other immune   system  disorders,  some elderly,  and  infants, can  be particularly  at risk from infections.  Those at  risk  should  seek  advice  about  drinking  water  from  the  health  care providers.  EPA/CDC  guidelines  on  appropriate  means to lessen the risk  of  infection  by  Crytosporidium  and  other  microbial  contaminants  are  available  from the Safe Drinking Water Hotline (1-800-426-4791).

 

All 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  call  the  Environmental  Protection  Agency’s  Safe Drinking Water Hotline (1-800-426-4791).

Total Coliform: The Total Coliform Rule requires water systems to meet a stricter limit for coliform bacteria. Coliform bacteria are usually harmless, but their presence 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. To comply with the stricter regulation, we have increased the average amount of chlorine in the distribution system.

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. Loxley 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 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.

MCL’s are set at very stringent levels.  To understand the possible health effects described for many regulated constituents, a person would have to drink two liters of water every day at the MCL level for a lifetime to have a one-in-a-million chance of having the described health effect.

 

Based on a study conducted by the ADEM with the approval of the EPA, a statewide waiver for the monitoring of Asbestos and Dioxin was issued.  Thus, monitoring for these contaminants was not required.

 

We at the Town of Loxley work around the clock to provide top quality water to every tap.  Please help us make this effort worthwhile by protecting our source water. Carefully follow instructions on pesticides and herbicides you use for your lawn and garden and properly dispose of household chemicals, paints and waste oil.  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.
