Dora Water & Gas Board

      2017 Annual Water Quality Report

 

 

Dora Water & Gas Board is pleased to present to you our 2017 Annual Water Quality Report. This report is for the calendar year of 2016 and is designed to inform you about the quality of 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 quality and protect our water resources. Our goal is to keep you informed about the excellent water service we provide. If you want to learn more, please attend any of our regularly scheduled meetings. They are held on the second Tuesday of each month at 5:30 pm at our office-10 Midway Plaza -Dora, AL 35062. The board members and officers are McArthur Sargent-Chairman, Norman Holt-Director, and Kristie Tuggle-Director. If you have any specific questions about this report or concerning your water utility, please contact Nina Absher or our office staff at (205) 648-6363.

 

In case of an EMERGENCY after normal office hours Monday through Friday or on weekends and holidays, call the Dora Police Department at (205) 648-9110. The Police Department will contact the person designated to respond for after-hours emergencies. Security of our water system has become a serious concern. We have taken steps to improve our security but we need the assistance of all our customers and the general public. Report any suspicious activities around our facilities to us immediately. We will promptly investigate all reports and involve law enforcement when any security breach is detected.

 

The Dora Water & Gas Board and our water supplier routinely monitor for constituents in your drinking water according to federal and state laws. The table in this report shows the results of our most current monitoring for the period ending December 31, 2016. Our drinking water meets federal and state requirements. All drinking water, including bottled drinking water, may be reasonably expected to contain at least small amounts of some constituents. It is important to remember that the presence of these constituents does not necessarily pose a health risk. Based on a study conducted by ADEM with the approval of EPA, a statewide waiver for the monitoring of asbestos and dioxin was issued. Thus, monitoring for these contaminants was not required.

 

The EPA has determined that your water is safe at the levels indicated in the following tables. 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 ˝ gallon of water every day at the MCL level for their entire lifetime to have a one-in-a-million chance of having any adverse health effect. 

 

Health Information

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 microbiological contaminants are available from the Safe Drinking Water Hotline 1-800-426-4791.

 

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 Dora Water & Gas Board is responsible for providing high quality drinking water, but cannot control the variety of materials used in household 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 at 1-800-426-4791 or at http://www.epa.gov/safewater/lead.

 

 

         

All drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants.  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 human activity. These substances can be microbes, organic or inorganic chemicals, pesticides, herbicides, or radioactive materials. 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 at 1-800-426-4791 or at http://www.epa.gov/safewater.

 

Source of Water & Water Treatment Techniques

We purchase our water from the Jasper Waterworks and Sewer Board. The source of their water is from the Mulberry Fork of the Warrior River. The Alabama Department of Environmental Management classifies the water facility as a Surface Water Source. The water is treated at the Laye-Williams Water Treatment Plant which has a capacity of 18 million gallons per day (MGD) of potable water.  Raw water from the river is pumped to the water treatment plant where it is aerated to oxidize taste and odor compounds.  Chlorine Dioxide is fed in the raw water either at the raw water pump station or prior to the rapid mix basin as a pre-oxidant to reduce disinfection by-product formation and to address potential taste and odor issues. Lime is added for pH adjustment and potassium permanganate is used to aid in the oxidation process and for organics removal.  As water enters the rapid mix chamber, alum is added as a coagulant. The water flows through three flocculation basins and three settling basins prior to entering the mixed-media filters.  Chlorine is added after filtration for disinfection and fluoride is added for protection of teeth.  Finished water is stored in clearwells with a total storage capacity of 4,785,000 gallons. The water is then pumped from the clearwells to the transmission and distribution system.

Source Water Assessment

Our water supplier, the Jasper Waterworks and Sewer Board, has completed an extensive source water assessment as required by the Alabama Department of Environmental Management.  No sites evaluated pose a significant risk to our customers.  Anyone wishing to view this report should contact their office at (205) 221-2141.  It has been determined by the assessment that the source water susceptibility ranking has a LOW risk potential.

 

Plain Language Definitions

In the following tables, you will find many terms and abbreviations that may not be familiar to you. To help you better understand these terms we've provided the following definitions:

 

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

 

Contaminant- Any substance other than water. Note that contaminants as defined, include dissolved minerals, purifying and dental health promotion additives.

 

Locational Running Annual Average (LRAA) - The average of sample analytical results for samples taken at a particular monitoring location during the previous four calendar quarters.

 

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. 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.

 

Maximum Contaminant Level Goal (MCLG) - The “Goal” (MCLG) is the level of a contaminant in drinking water which there is no known or expected risk to health.  MCLGs allow for a margin of safety.

 

Maximum Residual Disinfectant Level (MRDL) - The highest level of a disinfectant allowed in drinking water.  There is convincing evidence that the addition of a disinfectant is necessary for control of microbiological 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 disinfection to control microbial contaminants.

 

Millirems per year (mrem/year) - A measure of radiation absorbed by the body.

 

Minimum Detection Limit (MDL) - The Minimum Detectable Level for the contaminant.

 

 

 

Nephelometric Turbidity Unit (NTU) – A nephelometric turbidity unit is a measure of the clarity of water as it relates to particle count. Turbidity in excess of 5 NTU is just noticeable to the average person.

 

Non-Detects (ND) - Laboratory analysis indicates that the constituent was not detected in the water.

 

Non-Applicable (N/A) - MCL’s or MCLG’s are not applicable to these substances.

 

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 (ug/l) - One part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000.

 

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

 

Running Annual Average (RAA) – A compliance period where an average of four consecutive quarterly samples is used.

 

Total Haloacetic Acids (HAA5) - By –product of drinking water chlorination.

 

Total Trihalomethanes (TTHM) - By –product of drinking water chlorination.

 

Treatment Technique (TT) - A treatment technique is a required process intended to reduce the level of a contaminant in drinking water.

 

TOC- Total Organic Carbon

 

Variances and Exemptions –ADEM and EPA permission not to meet an MCL or a treatment technique under certain conditions.

  • Natural Gas smells like rotten eggs, and it is non-toxic, but flammable.

 

·        To detect a natural gas leak outside, look for dead vegetation, listen for hissing and blowing sounds, smell the odorant, which smells like rotten eggs.

 

·        IN THE EVENT OF A NATURAL GAS LEAK-leave the area immediately and call Dora Utilities at 205-648-6363

 

·        Make sure your natural gas appliances are free of dust and debris.

 

  • If you have a natural gas heater, look to make sure that there is enough clearance between the heater and curtains, furniture, or anything that would keep the heater from working properly.

 

  • When you light your appliance, make sure that it has a good burning pilot light with a sharp blue flame.

 

  • If you think you smell natural gas call Dora Utilities at 205-648-6363. In case of EMERGENCY after normal office hours Monday through Friday or on weekends and holidays, call the Dora Police Department at (205) 648-9110.

 

  • Call before you dig – It’s the Law.

 

  • Line location services are provided by Alabama 811 or 205-252-4444.  If you are making an addition, doing major landscaping, or installing fence post you must CALL 811 BEFORE YOU DIG!
