City of Perry 2010 Water Quality Report

Your water meets all state and federal regulations

Last year we conducted more than 1,217 tests for over 78 drinking water contaminants. We only detected three (3) contaminants. This brochure is an overview of the quality of the water we provided last year. Included are details about where your water comes from, what it contains, and how it compares to Environmental Protection Agency (EPA) standards. We are committed to providing you with the information because we want you to be informed. For more information about your water call: 478-988-2875 and ask for the Water Treatment Manager, Chad McMurrian.

Special population advisory

Some people may be more vulnerable to contaminants in drinking water than the general population. Immune 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 drinking water from their health care providers. EPA/Center For Disease Control guidelines on how to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline 1-800-426-4791.

Drinking water sources

Your water comes from wells which draw from the Cretaceous Sand Aquifer. These wells are protected from potential sources of contamination. Presence of certain constituents does not necessarily indicate that water poses a health risk. Source water assessment information and Wellhead Protection Plan may be obtained from City Hall. You may view this plan or request a copy by calling 1-478-988-2700.

Public participation opportunities

Perry City Council meets the first and third Tuesday of each month at 6:00 P.M. at City Hall. Your participation or comments are welcome at these meetings as well.

Contaminants in 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 EPA's Safe Drinking Water Hotline 1-800-426-4791.

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 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, 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 & herbicides, which may come from a variety of sources such as agriculture and residential use.
  • Radioactive contaminants, which are naturally occurring.
  • Organic chemical contaminants, including synthetic and volatile organic chemicals, which are byproducts of industrial processes and petroleum production, and also can come from gas stations, urban storm water runoff, and septic systems. 

Water quality monitoring

To ensure that tap water is safe to drink, EPA prescribes regulations that limit the amount of certain contaminants in water provided by public water systems. We treat our water according to EPA's regulations. Your water met all the regulations set by EPA. Food and Drug Administration regulations establish limits for contaminants in bottled water, which must provide the same protection for public health.

Water quality data

The table in this report lists all the drinking water contaminants we detected during the 2010 calendar year. The presence of these contaminants in the water does not necessarily indicate that the water poses a health risk. Unless otherwise noted; the data presented in this table are from testing done January 1 through December 31, 2010.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. 

Terms & Abbreviations

  • AL: Action Level- the concentration of a contaminant which, when exceeded, triggers treatment or other requirements that a water system must follow.
  • MRDLG: 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.
  • MRDL:Maximum residual disinfectant level- highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbiological contaminants.
  • MCL: Maximum Contaminant Level- 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.
  • MFL: million fibers per liter
  • mremf year: millirems per year (a measure of radiation absorbed by the body)
  • NA: not applicable
  • ND: not detectable at testing limit
  • NTU: Nephelometric Turbidity Units
  • pCijl: picocuries per liter (a measure of radioactivity)
  • ppm: parts per million or milligrams per liter - (corresponds to one minute in two years)

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 Perry 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 EPA’s Safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead

Our Water Treatment Plant Operators are on duty 24 hours to ensure your water is safe and provided in adequate supply. All Operators are licensed by the State of Georgia and receive continuing education to maintain a high level of proficiency and expertise. A series of tests are preformed three (3) times daily to ensure consistent quality. These tests include; pH, Fluoride, Iron and Phosphate (corrosion inhibitor) and Chlorine residual. You can view this report online at www.perry-ga.gov or if you have any questions about your water quality you can visit these other informative sources.

Water Supply and Production

The City of Perry water system (" the System ") currently has a total permitted production capacity of 6.15 million gallons per day (MGD). This capacity includes the 1.0 MGD at the Main St. Water Plant Facility and an additional 5.15 MGD from the Woodlawn Water Treatment Plant Facility. These water plants receive raw water for treatment from five wells at various locations around the city. The System currently has five elevated potable water tanks which serve as a1.75 million gallon emergency water storage reservoirs and also assist in the production of water pressure within the distribution system.

Distribution

The Water System includes more than 148.5 miles of water mains in various diameters and materials. All water lines are constructed by the Water System's own crews, contracted for with the construction monitored and approved by the Water System's engineer, or are constructed by sub-dividers and contributed to the Water System upon approval of the construction by the Public Works Director.

Water Restrictions

Most Recent Water Restriction Information:

The Georgia Water Stewardship Act went into effect statewide on June 2, 2010.  It allows daily outdoor watering for purposes of planting, growing, managing, or maintaining ground cover, trees, shrubs, or other plants only between the hours of 4 p.m. and 10 a.m. by anyone whose water is supplied by a water system permitted by the Environmental Protection Division. 

Outdoor water use for any purposes other than watering of plants, such as power washing or washing cars, is still restricted to the current odd/even watering schedule.

  • Odd-numbered addresses can water on Tuesdays, Thursdays and Sundays. 
  • Even-numbered and unnumbered addresses are allowed to water on Mondays, Wednesdays and Saturdays. 

More information about the outdoor water use schedules can be found on the EPD web site at http://www.georgiaepd.com/.

Groundwater Wells

  • The City of Perry has five (5) groundwater well's
  •  Wells pump water to the plants for treatment
  •  Permitted to withdraw 4.5 MGD annually and 6.15 MGD monthly
  •  Former permit limits were 2.4 MGD annually and 2.8 MGD monthly
  •  Wells are checked and maintained daily
  •  Water table levels are documented bi-weekly

Aeration

  • Removes dissolved gases and other undesirable compounds from the water through volatilization
  • Aeration releases CO2 and vents it into the atmosphere, therefore increasing pH 
  • Reduces tastes and odors caused by naturally occurring elements in the water

Chemical Addition

Lime is added following aeration to increase the pH to above 7.5 SU
Good pH has several effects:

–   pH and temperature controls other chemical and physical reactions in other phases of treatment
–   Prevents corrosion of piping materials throughout the distribution system
–   Protects the pipes inside your home
–   Prevents leaching of pipe materials into the water

Settling Tanks

  • The velocity of the water is slowed down to allow settling of sand, silt, or other undesirable solids
  • Typically basins are designed with 2 hours of detention time
  • Settled solids must be removed regularly from the floor of these basins
  • The clarity of the water is an indicator of performance

Filtration

  • Water is filtered following sedimentation
  • Perry has four (4) sand filters for Iron removal

Disinfection

  • Clear water from the sand filters is discharged and dosed with chlorine for disinfection
  • We feed enough chlorine gas to maintain approximately 1.0 PPM free chlorine residual in the distribution system
  • Perry uses approximately 20 pounds per day of chlorine gas to treat the drinking water

Fluoridation

  • Immediately following chlorination for disinfection, the water is treated with Fluoride to prevent tooth decay
  • Exposure to high doses of Fluoride for prolonged period of times can damage teeth, by “mottling” (spotting/streaking)

Clear Wells

  • Immediately following disinfection the treated water is stored in a clear well for additional contact time with the chlorine for disinfection purposes
  • Desired contact time for the treated water with the chlorine is 30 minutes
  • High Service Pumps pump the water from the clear well to the distribution system

Distribution System

  • Once the water is in the piping system of the distribution system it is ready for consumption
  • EPD requires we maintain a minimum of 20 PSI in the distribution system
  • Perry’s pounds per square inch averages approximately 60 PSI

Booster Pumps

  • If the distribution system requires additional pressure based on demand or a main break, the plants are equipped with booster pumps to increase pressure
  • This could be critical in a fire situation
  • Perry is equipped with one (1) booster pumping station, including two separate pumps

Elevated Tanks

  • Perry’s distribution system is equipped with five (5) elevated storage tanks
  • These tanks help maintain pressure and contain large amounts of water to be used in times of peak demand or high consumption rates
  • In an emergency, we have enough water in storage to maintain supply for approximately 12 hours based on our current usage

Laboratory Analyses

  • Permit and process control samples are analyzed by lab personnel
  • All analyses are documented and confirmed using a quality assurance and quality control (QA/QC) program
  • Known standards are analyzed to verify test procedures were followed correctly
  • If data does not meet QA/QC standards, the test must be repeated for accuracy
  • All lab data is reported monthly to EPD

Maintenance

  • Operations personnel are responsible for preventative and corrective maintenance of the water treatment plant and related equipment
  • Infrared, vibration analyses, voltage and amperage tests are part of our routine maintenance program

Solids Handling

  • Solids collected and removed by the sand filters are pumped to a holding pond
  • This holding pond is cleaned regularly with final disposal in the landfill

SCADA

  • Supervisory Control and Data Acquisition system
  • The City’s water system is equipped with telemetry that allows us to see what is going on out in the system and control it through a computer at the water treatment plant
  • Operators use computers and data management software to track and record data on the water system and generate reports
