Status Updates regarding the PFOA/PFOS Water Advisory
Drinking Water Available from Water Tanker at City Hall
The water tanker across the street is available for use 24 hours a day for drinking water, please remember to bring your own container. The City of Summerville will no longer be distributing bottled drinking water.
Test Well Status
The City of Summerville first test well is producing 600 gallons (the max capacity of the pump used for testing) of water per minute (GPM) at a depth of 364ft. This well will still need to be developed into a production well, and then connected to the City of Summerville water distribution system upon approval from Georgia EPD. The engineers send plans and specs to the Georgia EPD for approval of all phases of the project.
The City of Summerville Public Works has laid 2,000 feet of 16” pipe on Filter Plant Road in preparation for connecting the new well to the City's water distribution system. Another delivery of 4,000 feet of 16” pipe is expected by September 1st. With the completion of this additional pipe installation on Filter Plant Road, the City will stop at the intersection of Highway 48 until Georgia DOT has approved plans for the installation of another 12,000 feet of 16” pipe to the City’s production well site off of Highway 48.
How much has it cost to build the new well so far?
As of July 31, 2020 the City has invested $128,702.75 in the test well.
To reduce the overall cost of the project, the City has self-performed the installation of 2,000 feet of a 16” water line on Filter Plant Road. Another delivery of 4,000 feet of 16” pipe is expected by September 1st.
How much more is it expected to cost to complete the well?
The cost of a production well is undetermined because this will be a bid process. The City is actively pursuing multiple grants and funding for a permanent production well, along with procuring property for additional well sites. Final costs are not known at this time. There is no estimate on the completion date.
Funding of the remaining 16” water pipe to the well site is also being pursued.
Carbon Based Pilot Study for Removal of PFOA/PFOS
The City of Summerville is working with a pilot study using carbon as a removal method of PFOA/PFOS at the Raccoon Creek Water Treatment Plant. This system is referrerd to as granulated activated carbon (GAC). Test results have been promising. More information will be provided with available. The engineers have provided an updated start date for installation of the week of September 21st and the goal is to complete the installation within 3-5 days of starting installation. Once the filters are installed, samples will be collected and tested for the presence of PFOA/PFOS.
What was the cause of the August 20th Boil Water Advisory?
Fecal indicators were present in Chattooga County Well #7 and infiltrated into a portion of the City’s water distribution system, because we were purchasing water from Chattooga County. With the water from our Lowe Spring Plant and Chattooga Well #7 the City was able to provide water to a section of the water distribution system that was PFAS free. Due to the corrective action of Chattooga County for well #7, the boil water advisory was lifted by the EPD.
Complete Notice of Drinking Water Health Advisory Level Exceedance for Raccoon Creek Water Plant, Affecting City of Summerville Public Drinking Water System
On January 30, 2020 sample results came back showing combined levels of PFOA and PFOS in the finished water from the Raccoon Creek treatment plant of 98 parts per trillion, which is above the U.S. EPA Health Advisory Level. In addition, combined levels of PFOA and PFOS in the Goodwin Hill Tank were found to be 92 parts per trillion.
In light of the EPA Health Advisory, the City of Summerville, in consultation with the Georgia Environmental Protection Division (Georgia EPD), has determined that we need to notify you of this new information, update you on what it means and what we are doing about it. As more information becomes available, we will provide additional updates.
What are PFOA and PFOS?
PFOA and PFOS are fluorinated organic chemicals that are part of a larger group of chemicals referred to as perfluoroalkyl substances (PFASs). PFOA and PFOS have been the most extensively produced and studied of these chemicals. They have been used to make carpets, clothing, fabrics for furniture, paper packaging for food and other materials (e.g., cookware) that are resistant to water, grease or stains. They are also used for firefighting at airfields and in a number of industrial processes. Because these chemicals have been used in an array of consumer products, most people have been exposed to them.
What is the Health Advisory Level?
To provide Americans, including the most sensitive populations, with a margin of protection from a lifetime of exposure to PFOA and PFOS from drinking water, EPA established health advisory levels at 70 parts per trillion. When both PFOA and PFOS are found in drinking water, the combined concentrations of PFOA and PFOS should be compared with the 70 parts per trillion health advisory level. This health advisory level offers a margin of protection for all Americans throughout their life from adverse health effects resulting from exposure to PFOA and PFOS in drinking water.
What are the potential adverse health effects with exposure to PFOS and PFOA?
EPA's health advisories are based on the best available peer-reviewed studies of the effects of PFOA and PFOS on laboratory animals (rats and mice) and were also informed by epidemiological studies of human populations that have been exposed to PFASs. These studies indicate that exposure to PFOA and PFOS over certain levels may result in adverse health effects, including developmental effects to fetuses during pregnancy or to breastfed infants (e.g., low birth weight, accelerated puberty, skeletal variations), cancer (e.g., testicular, kidney), liver effects (e.g., tissue damage), immune effects (e.g., antibody production and immunity), thyroid effects and other effects (e.g., cholesterol changes).
EPA's health advisory levels were calculated to offer a margin of protection against adverse health effects to the most sensitive populations: fetuses during pregnancy and breastfed infants. The health advisory levels are calculated based on the drinking water intake of lactating women, who drink more water than other people and can pass these chemicals along to nursing infants through breastmilk.
What should you do?
Pregnant women, nursing mothers and infants are most sensitive to these chemicals and can reduce their potential risk by not consuming water from the City of Summerville public water system. In an abundance of caution, until further notice, these groups may want to consider using water from another source for consumption purposes. Recommendations for these sensitive groups include:
- Use bottled water for drinking and cooking of foods that absorb water (like pasta).
- Use formula that does not require adding water or use bottled water intended for infants to make formula.
The water can be used for washing foods, brushing teeth, bathing and showering, provided that care is taken to avoid swallowing water during those activities.
Point of use filters are available for consumers. Look for NSF/ANSI 53 (for carbon filters) or NSF/ANSI 58 (for reverse osmosis) certification.
Please note that boiling the water will not destroy these chemicals and will somewhat increase their levels in the water. If you have specific health concerns regarding your exposure, you should consult a health professional, such as your doctor.
What is the City of Summerville doing?
The City of Summerville is or has taken the following actions:
- The City is providing notice by mail to all customers.
- The City has contacted local media, including newspaper, radio, and social media.
- The City provided direct notification to all elementary schools, day care facilities, and health care facilities.
- The City is providing clean water distribution from a centralized fill station located at City Hall. The water tanker is located next to City Hall at 120 Georgia Avenue, Summerville, GA and is available 24 hours a day, 7 days a week. The fill station is self-serve and customers will need to bring their own containers to fill with water.
- The City is investigating treatment options for the Raccoon Creek treatment plant. This includes a pilot study with carbon filters as a removal method of PFOA/PFOS.
- The City is investigating well sites and the Georgia EPD has given the city clearance to drill 2 test wells. The first test well has completed drilling.
- The City is investigating increasing the usage of water sources other than the Raccoon Creek treatment plant. These sources include the City's Lowe Springs, which was also sampled at the same time and the results show that no PFOS or PFOA was detected. The City also has interconnections with nearby public water systems and is purchasing water from Chattooga County Water District & the Town of Trion in order to decrease the amount of water coming from Raccoon Creek.
