Brunswick County statement in response to Environmental Working Group January 2020 report

01.22.2020

Brunswick County began an extensive testing program for PFAS contaminants when academic studies revealed the presence of multiple PFAS in its drinking water, testing a suite of PFAS contaminants on a weekly basis. Brunswick County’s water samples have continuously remained below the EPA’s established health advisory levels for PFOA + PFOS and the North Carolina Department of Health and Human Services’ established provisional health goal for GenX, however the combined levels of all PFAS is concerning and the County continues to test and monitor for most known PFAS compounds and GenX during its routine testing.

At this time, the EPA does not have an established health goal for several of the other compounds listed in this report that are contributing to the overall 185.9 ppt sample level, however the PFOA + PFOS and GenX sample levels in this report are also below the provisional health goals mentioned above. Due to the fact that little or no study has been done on the health effects of combined PFAS or many of these individual PFAS found in the source water, Brunswick County has taken a proactive approach to install the most protective water treatment system at the Northwest Water Treatment Plant to remove these contaminants.

Brunswick County’s leadership recognizes that high quality water is of paramount importance to our customers and residents and agree that reverse osmosis is the most effective PFAS removal technology, which is why the Board of Commissioners and county administration are embarking on a project to install an advanced low-pressure reverse osmosis treatment system at the Northwest Water Treatment Plant, as well as increase capacity at the plant to support the county’s growth. Brunswick County Public Utilities has been working diligently with engineers at CDM-Smith and the North Carolina Department of Environmental Quality to design, permit and build an economical low-pressure reverse osmosis system at the plant for the benefit of all Brunswick County water users.

Low-pressure reverse osmosis is considered one of the most advanced and effective methods to treat and remove both regulated and unregulated materials from drinking water, including GenX, 1,4-dioxane and other per- and polyfluoroalkyl substances (PFAS). In April 2018, the County conducted two rounds of testing on a pilot low-pressure reverse osmosis system at the Northwest Water Treatment Plant. The results showed that low-pressure reverse osmosis reduced most PFAS including GenX to undetectable levels, essentially removing all the components.

Not only do pilot studies indicate that low-pressure reverse osmosis is the most effective advanced treatment method for PFAS removal, but they also indicate that it is the most economical advanced treatment option for the removal of high percentages of PFAS at the Northwest Water Treatment Plant. Most previous studies focus on the high-energy cost when using reverse osmosis for the treatment of saline or brackish water, but the cost is considerably less when used to treat fresh water for PFAS contaminants, especially short-chain PFAS.

All of the County’s water sample test reports are available to the public at https://www.brunswickcountync.gov/genx/

Brunswick County would notify customers and residents should any of its test samples exceed the health advisory levels established for PFOA + PFOS or GenX.

FAQs about the EWG January 2020 Report

FAQs about the EWG January 2020 Report

Updated as of Jan. 28, 2020

  1. What is the County’s reaction to the EWG January 2020 report?
    • Brunswick County began an extensive testing program for PFAS contaminants when academic studies revealed the presence of multiple PFAS in our drinking water.
    • Our Public Utilities staff test for a suite of PFAS contaminants on a routine basis. All results are published on our website at https://www.brunswickcountync.gov/genx/
    • The County is concerned about PFAS levels in our water and is proactively installing a low-pressure reverse osmosis system at the Northwest Water Treatment Plant to remove these contaminants.
  2. Is the water safe to drink and use?
    • Brunswick County’s water samples have continuously remained below:
      • The EPA’s established health advisory levels for PFOA + PFOS and
      • The State’s established provisional health goal for GenX (North Carolina Department of Health and Human Services)
    • The County is concerned about the combined levels of all PFAS in water samples and continues to test and monitor for most known PFAS compounds and GenX.
    • Brunswick County will notify customers and residents immediately should any of its test samples exceed the health advisory levels.
  3. What is the County going to do going forward?
    • Because there are little or no studies on the health effects of combined PFAS components, the County is proactively installing an advanced low-pressure reverse osmosis treatment system at the Northwest Water Treatment Plant.
    • Low-pressure reverse osmosis is the most protective water treatment system to treat and remove both regulated and unregulated materials from drinking water, including GenX and PFAS compounds.
  4. When will the low-pressure reverse osmosis system be built/ready?
    • We are working diligently with engineers at CDM-Smith and the North Carolina Department of Environmental Quality to design, permit and build an economical low-pressure reverse osmosis system at the plant for the benefit of all Brunswick County water users.
    • We are currently in the permitting stage and the estimated date of completion will be more determinable after the County receives its NPDES permit from DEQ and after the Board of Commissioners selects which bid alternate to proceed with.
      • Bids are expected to be received March 5.
    • There are currently four bid alternates the Board will consider, each with a different scope and timeline to provide flexibility with concern to cost.
  5. Why are the PFAS levels so high?
    • The PFAS levels can fluctuate from sample to sample and week to week. Some reasons include:
      • Fluctuations from possible Fayetteville Works plant discharges
      • Fluctuations in river flow that affects the dilution of discharges from upstream
    • Brunswick County recognizes that these numbers are of concern to our residents and customers, which is why we are installing the low-pressure reverse osmosis system.

FAQs for the Northwest Water Treatment Plant Project

FAQs for the Northwest Water Treatment Plant Project

Updated as of Jan. 28, 2020

Project Schedule and Bid Alternates

  1. When will the expansion and upgrades project at the Northwest Water Treatment Plant finish?
    • The estimated date of completion will be more determinable after the Board of Commissioners selects which bid alternate to proceed with.
    • The Board will determine which bid alternate to construct after bids are received on March 5.
  2. How many bid alternates is the County considering for this project?
    • Addendum #3 was issued Dec. 19, 2019; it simplified the bid form and reduced the number of bid alternatives from 10 to four.
    • The addendum also clarified the basis of award, which will provide a clearer indication of the apparent low bidder once the bids are opened.
  1. What are the differences between the four bid alternate?
    • Each bid alternate has a different scope and timeline to provide flexibility with concern to cost. Each bid alternate establishes deadlines for operational use of the conventional treatment expansion, for operational use of the advanced low-pressure reverse osmosis system, and for final completion of all work.

    • Overview of the Bid Alternates
      • Bid Alternate #1: This alternate revises the deadline for beneficial use of the first five low-pressure reverse osmosis units to May 15, 2023. It also adds three more units (No. 6-8) to the bid with a deadline for beneficial use of Aug. 15, 2023, to determine whether the County can afford to proceed with installing eight units as part of this project. The final acceptance of all work (including the expansion project) has a deadline of Nov. 15, 2023.
      • Bid Alternate #2: This alternate revises the deadline for the beneficial use of four low-pressure reverse osmosis units to May 15, 2023, and with a final acceptance of all work (including the expansion project) by Nov. 15, 2023.
        • The alternate removed a fifth low-pressure reverses osmosis unit from the bid, preceding with four. Additional units could be installed in the future per the Board’s approval.
      • Bid Alternate #3: This alternate revises the deadline to have beneficial use of five low-pressure reverses osmosis units to Nov. 15, 2022. The revised deadline for final acceptance of all work (including the expansion project) is Feb. 15, 2023.
      • Bid Alternate #4: The alternate removes the low-pressure reverse osmosis process improvements from the bid. It includes only the work for the plant’s expansion project. The deadline for beneficial use of the conventional treatment process is May 15, 2022. The revised final acceptance of all work is Aug. 15, 2022.
        • Brunswick County’s leadership remains committed to installing a low-pressure reverse osmosis system at the Northwest Water Treatment Plant. This is not an option the County is actively pursuing but is requesting bidders submit the information to have on file just in case.
  2. Why did the project completion dates and operational use of the advanced low-pressure reverses osmosis system get pushed back?
    • Although excessive permitting review time frames have impacted the project schedule, Brunswick County is committed to providing additional capacity and advanced treatment as soon as is practical.
    • The County adjusted the bidding schedule after the North Carolina Department of Environmental Quality (DEQ) adjusted its schedule for the NPDES permit review process and several contractors expressed concern regarding the amount of time to prepare bids and their ability to meet the current project schedule.
  3. Why does Bid Alternative #4 not include the option to include an advanced low-pressure reverse osmosis system?
    • Brunswick County’s leadership remains committed to installing a low-pressure reverse osmosis system at the Northwest Water Treatment Plant.
    • DEQ issued a draft NPDES permit for the project Nov. 5, 2019, and the County will continue to work closely with DEQ and provide information and details as needed to ensure a smooth review process.
    • Other factors such as bid price, project budget, and NPDES permit status will be considered when the Board makes it decision.
  4. How will the County award the bids for the projects?
    • Bids are scheduled to be received March 5. The Board of Commissioners will determine which bid alternate to construct after bids are received.
    • The consultant provided the following instructions to bidders under Section 10 – Bid Evaluation and Bidder Qualifications:
      • “Contract award will be based on the responsible Bidder with the lowest Base Bid identified in the Form of Proposal. In addition, the Owner may select any of the Alternative Bid Items provided by the Bidder with the lowest Base Bid. Discrepancies on the Bidder’s proposal shall be resolved based on the Owner’s inspection and interpretation of the proposal as a whole. In cases where it is not evident what portion of a proposal is errant, discrepancies shall be resolved as follows.”
  5. How long is it expected to take the County to review bids, award a contract(s) and issue a notice to proceed?
    • The project is currently open for bid with the bid date rescheduled for March 5, 2020. Notice of Award is anticipated to be issued April 20, 2020, with the Notice to Proceed to be issued in early May 2020.

Low-Pressure Reverse Osmosis, Expanding Capacity, and PFAS

  1. What is the project at the Northwest Water Treatment Plant going to accomplish?
    • This three-phase project will expand the plant’s water treatment capacity from 24 million gallons per day (MGD) to 36 MGD to support the projected increase of residential, commercial, and industrial water use in the county.
    • It will feature an advanced low-pressure reverse osmosis water treatment system, which is considered one of the most advanced and effective methods to treat and remove both regulated and unregulated materials from drinking water, including GenX, 1,4-dioxane and other per- and polyfluoroalkyl substances (PFAS).
  2. Why do we need more capacity at the Northwest Water Treatment Plant?
    • With a population nearing 135,000 residents and growing, Brunswick County is expanding its capacity at the plant to provide an adequate and reliable supply of water to support all of Brunswick County’s residential, commercial, and industrial needs both now and in the future.
  3. What else is the County doing about PFAS and GenX?
    • Brunswick County Public Utilities conducts routine water tests of our raw and treated water from the Northwest Water Treatment Plant.
    • Brunswick County’s treated drinking water remains under the threshold for the EPA’s federal health levels for PFAS, PFOA, and GenX.
    • All water test results are published on the County’s website at https://www.brunswickcountync.gov/genx/
    • The EPA does not currently have health levels set for other PFAS, such as PFMOAA. The County routinely monitors and tests for other known contaminants in the PFAS family.
    • In April 2018, the County conducted two rounds of testing on a pilot low-pressure reverse osmosis system at the Northwest Water Treatment Plant. The results showed that low-pressure reverse osmosis reduced most PFAS including GenX to undetectable levels, essentially removing all the components.
  1. What is a NPDES permit and why is it important?
    • A National Pollutant Discharge Elimination System (NPDES) permit allows the permit holder to discharge a variety of approved discharges to surface waters or to a separate storm sewer system in accordance with terms and conditions set by DEQ.
    • DEQ issued a draft NPDES permit for the project Nov. 5, 2019. An NPDES permit is necessary to receive construction financing approval from the Local Government Commission.
Frequently Asked Questions (FAQ)

Frequently Asked Questions

 

How will BCPU ensure the water is safe once Low Pressure Reverse Osmosis is implemented?

  • BCPU has studied remineralization  extensively with our LPRO pilot unit and has designed a  system that will be adding minerals back to the water after it is treated with reverse osmosis. Remineralization is not new technology, it is very common to have to add minerals back to the water so it is not aggressive on distribution pipes and household plumbing fittings.   Once the water has passed through the LPRO, calcium carbonate (lime) will be fed at a specified dose to add back some minerals, hardness, and alkalinity, then carbon dioxide will also be added to reduce the pH back to normal drinking water levels (7-8.5pH) while also stabilizing the hardness and alkalinity.  Another process mandated by the State, is for BCPU to use orthophosphate, this aids in preventing corrosion to our pipes and the plumbing in our homes by putting a micro fine layer of phosphate on our pipes.  Currently we monitor for corrosion of household plumbing fixtures and piping by conducting lead and copper sampling throughout the water system on homes known to have copper pipe with lead solder.  We also monitor certain parameters daily at the treatment plants and weekly in the distribution system to ensure our water is safe and won’t corrode our pipes or your household plumbing. gw

What is GENX?

  • According to DuPont Chemours, GENX is a technology developed to make high-performance polymers used in cabling, cookware non-stick coatings, laptops, cell phones, and a host of similar applications. The processing aid associated with the process is commonly referred to as GENX. GENX replaces the use of PFOA (perflurooctanaic acid).

What do we know about GENX?

  • We know that the EPA has not yet developed a drinking water regulation for this contaminant and that there is limited information available on it. Ultimately, EPA will determine potential impacts and safety standards.

What is a contaminant?

  • The EPA’s Web site states, “The Safe Drinking Water Act (SDWA) defines ‘contaminant’ as any physical, chemical, biological, or radiological substance or matter in water. Drinking water may reasonably be expected to contain at least small amounts of some contaminants. Some contaminants may be harmful if consumed at certain levels in drinking water. The presence of contaminants does not necessarily indicate that the water poses a health risk.”

What is the difference in PFOA (C8) and GENX?

  • Both chemicals are used in the production of plastics, water/stain repellants, firefighting foams, and food-contact paper coatings and have similar, but not identical, chemical characteristics. GenX and other perfluoroalkyl ether carboxylic acids (PFECAs) are replacing PFOA (C8) and other polyfluoralkyl chemicals (PFASs) due to their purported rapid bioelimination (elimination from the body). Both chemicals are unregulated by the EPA for drinking water standards. However, more studies are available on PFOA (and a similar chemical, PFOS) than for GenX. The EPA has established a lifetime health advisory level for PFOA and PFOS of 70 parts per trillion, though there is not a similar health advisory level for GenX.

What are these chemicals used for?

  • Fluoropolymer-based materials that contain PFOA, PFOS, and GenX are found in several different environments that humans are regularly exposed to. According to DuPont, the company’s fluoropolymers are used in non-sticking coatings for cookware, breathable water repellent clothing for outdoor, military, medical and clean room activities. In addition to cookware and clothing, fluoropolymers are used to make things lighter, like laptop computers, cellphones, media players and home theaters.
  • The EPA’s Drinking Water Lifetime Health Advisory level for PFOA and PFOS is 70 parts per trillion. According to the EPA fact sheet, EPA scientists take into account other means of exposure when determining a health advisory. So, exposure routes such as air, food, dust, and consumer products are taken into consideration when determining the health advisory for drinking water.

When did Brunswick County learn about GENX?

  • Brunswick County was not aware of the presence of GENX in the Cape Fear River, or the study performed by researchers from N.C. State University, until recent media reports.

How is GenX measured?

  • Measurements of GenX are commonly reported as parts per trillion (PPT) or as nanograms per liter (ng/L). According to the EPA, these two forms of measurement are equivalent (1 PPT is the same as 1 ng/L), and both are equivalent to one drop in one trillion gallons of water.

What health guidelines or regulatory limits are available?

  • There are no U.S. regulatory guideline levels for GENX. However,on July 14, North Carolina Health and Human Services released an updated preliminary health assessment for concentrations of the unregulated compound GenX in finished, or treated, drinking water. The revised health goal for exposure to GenX in drinking water is 140 nanograms per liter (also referred to as parts per trillion). This updated health goal of 140 parts per trillion is expected to be the most conservative and health protective for non-cancer effects in bottle-fed infants, pregnant women, lactating women, children and adults. This health goal is lower than the health goal in the initial preliminary health assessment. This change reflects information from new data. For more information about the initial and revised assessments, visit https://www.ncdhhs.gov/news/press-releases/joint-deq-dhhs-release-state-releases-first-water-quality-data-updated-health.

What is a Lifetime Health Advisory?

  • The EPA issues Health Advisories for some chemicals, guidelines which offer an estimate of acceptable limits for daily consumption that are not expected to cause adverse health effects (which vary by chemical and advisory, but can include health effects like cancer, thyroid effects and/or liver effects) to vulnerable populations (such as infants, pregnant woman or elderly persons). The health advisories refer to different time frames, and give an estimate of an acceptable limit for consistent daily consumption over that period of time without adverse health effects. A one-day health advisory refers to concentrations of a chemical in drinking water that are not expected to cause adverse health effects for up to one day of exposure. A ten-day health advisory refers to a concentration that is not expected to cause adverse health effects for up to ten days of consistent daily exposure at that level (based on a 10 kg/22 pound child consuming one liter of water per day).
  • A lifetime health advisory refers to a concentration that is not expected to cause adverse health effects over a lifetime of consistent daily exposure at that level (based on a 70 kg/154 pound adult consuming two liters of water each day). These advisories are not enforceable standards, but are meant to serve as guidance, and are based on scientific studies.

Who benefits from the lawsuit that Brunswick County filed against Chemours and DuPont?

  • Brunswick County Public Utilities customers will benefit from the lawsuit. It is protecting these customers’ interests and needs.

Why did Brunswick County file a lawsuit against Chemours and DuPont?

  • Brunswick County filed suit against Chemours and DuPont to protect Brunswick County Utilities customers and their long-term water needs. The lawsuit is looking at the interests of Brunswick County’s customers in the long run and protecting customers against new and emerging chemical compounds.

What steps can I take at home? Is there a home filtration system that will remove GenX?

  • There is very little information currently available regarding GenX and filtration, at the utility level and at the home or individual system level. Some scientists and researchers speculate that certain filtration types might remove GenX from drinking water; however, at this time there is no firm data showing whether or not these systems actually do, and state officials have no recommendations regarding home filtration systems. If data becomes available to Brunswick County regarding proven steps that residents can take, including home filtration systems, we will share it at www.brunswickcountync.gov/genx.

Will boiling my water remove Genx?

  • There would not be any expected benefit to boiling water in order to remove GenX, because it is a chemical compound.

What about reverse osmosis?

  • Reverse Osmosis is known as an effective treatment technology for the removal of very small size particles, inclusive of essential minerals, many chemical compounds, and bacteria. Each drinking water treatment method has its own advantages and disadvantages.

Should I drink bottled or distilled water?

  • The health needs and situations of individuals vary widely and the use of bottled water or distilled water is an individual decision that should be discussed with your physician.

Will there be bottled water provided?

  • At this time, there are no plans to provide bottled water.

With GENX in the Cape Fear River, what can/will Brunswick County do to ensure the water is safe?

  • Brunswick County Public Utilities treats its source water above and beyond current state and federal standards and maintains a robust sampling and monitoring schedule. Additionally, we believe in the importance of participating in studies to ensure that emerging compounds are discovered and appropriately regulated to protect drinking water utilities and their customers. BCPU believes the best next step is to determine if this compound needs to be regulated. Additionally, Brunswick County supports and encourages efforts by Department of Environmental Quality (DEQ) to eliminate discharges of chemicals into the river that have possible detrimental impacts on drinking water source quality. You can view BCPU’s water quality reports, with information about Brunswick County’s water system and the sampling mentioned above, online.

Does BCPU monitor for GENX?

  • Brunswick County is working with the Department of Environmental Quality and other utilities in the region to provide testing for both the raw source water in the Cape Fear River and the finished water within the distribution system of these utilities. Results of testing that has been performed, by Brunswick County and by NCDEQ, can be viewed on this page under the “Brunswick County Water Testing Results” tab.
  • For more information on permitting and compliance enforcement, please contact the State of North Carolina Department of Environmental Quality–the agency responsible for monitoring and regulating discharges on the river.

Why do the test results from the week of July 3 show more GenX in the treated water than in the raw?

  • Each analytical test has what is called a window of variability: the analytical method has many steps that have to be followed and each one will have slight variations, the calibration curves will look slightly different from one test to the next, sample spike recoveries will be slightly different from test to test. It doesn’t mean they are wrong,  just that there are slight variations in each test and when two results are within 1.8% of each other in the parts per trillion realm they can appear to be higher than one would perceive they should be; in this case the finished water was higher than the raw water. Then you have the variability in the actual water being sampled. The two water samples are collected at the same time but represent two different water qualities and stream flows. The finished water sample is water that came down the raw pipe twelve hours earlier than the raw water sample was collected as that is how long it takes the water to pass through all the treatment processes.

Has Brunswick County tested for or found any similar substances?

  • Every five years, the EPA develops a list of contaminants of interest for local utility providers to monitor. The contaminants are not subject to regulation, but are known or anticipated to be in public water systems, and may require future regulation. In 2014 and 2015, testing performed by Brunswick County in compliance with this monitoring rule did show some amounts of the PFOA, sometimes referred to as C8, and PFOS compounds. In 2016, the health advisories were lowered, but the amounts Brunswick County had found were below the new health advisories. The results of these tests were reported to customers in the County’s annual Water Quality Report, which is sent to each customer and posted on the county’s website, where it remains viewable online. These results were also reported to the EPA and NCDEQ.

Is Brunswick County doing anything about 1,4-Dioxane?

  • Every five years, the EPA develops a list of contaminants of interest for local utility providers to monitor. The contaminants are not subject to regulation, but are known or anticipated to be in public water systems, and may require future regulation. As part of testing for this list of contaminants, in 2015 Brunswick County did detect levels of 1,4-Dioxane, below EPA Health Advisory Levels issued at that time. The results of this testing were reported to customers in the County’s annual Water Quality Report, which is sent to each customer and posted on the county’s website (https://www.brunswickcountync.gov/files/utilities/2015/02/CCR_2015.pdf). The results were also reported to the EPA and NCDEQ. Brunswick County is consulting with NCDHHS and has requested additional information and clarification regarding health advisories and cancer risks for this chemical.

Is Brunswick County looking into cancer rates in our area, or a connection between cancer rates and chemicals in our water?

  • NC Department of Health and Human Services has been looking into the rates of cancer, and specific types of cancer, comparing those rates to statewide rates to look for anomalies. After Chemours informed area officials that the presence of GenX in the Cape Fear River may have started decades earlier than initially indicated, NC DHHS researchers began examining these rates over a wider timeframe.

Can customers put a filter on their tap to remove GENX?

  • GENX is a new, unregulated compound and we are unaware of technologies capable of removing it from the water at this time. We will provide more information as it becomes available.

What is being done about this situation?

  • Since we were made aware of the presence of GENX in the Cape Fear River, we have been in constant communication with other area utility providers, state and federal government, and private agencies to learn as much as we can about the chemical, its potential impacts, and what steps to take next.

On June 15, Brunswick County Commissioners Chairman Frank Williams, County Manager Ann Hardy and Health and Human Services Executive Director David Stanley met with officials from Chemours and local and state agencies. At this meeting, Chemours officials stated that the GenX compound found in the Cape Fear River was likely a byproduct of another manufacturing process at the same location, and not due to discharge from the plant making GenX.

After the meeting, Brunswick County officials joined other local officials in asking Chemours to cease discharge of GenX into the Cape Fear River immediately, while regulatory authorities make a determination of the chemical. The Chairman’s notes from the meeting and video of the press conference held after are available at www.brunswickcountync.gov/genx.

At the June 19 regular Board of Commissioners meeting, the Board passed a resolution requesting that Chemours halt any process resulting in discharge of GenX into the Cape Fear River and approved funding for a consultant to provide specialized technical assistance.

NCDEQ and NC DHHS are leading a state investigation into the presence of GenX in the Cape Fear River, and are pushing Chemours to limit the amount of GenX being released into the river. NCDEQ is collecting water samples and sending them to a laboratory in Colorado which is capable of detecting GenX at low concentrations.

Will Rep. Rouzer be involved?

Is a map available showing locations within the Brunswick County service area that receives source water from the Cape Fear River?

  • The Northwest Water Treatment Plant (Cape Fear River source water) can and sometimes does provide water throughout the Brunswick County water system. While some areas of the system typically receive water from one plant or the other, a map has not been provided because it may be misinterpreted to indicate that some customers may never receive water from the Northwest Water Treatment Plant. Areas that typically receive water from the 211 Groundwater Treatment Plant include Bald Head Island, Caswell Beach, Oak Island, Southport, and St. James. All other areas typically receive water from the Northwest Water Treatment Plant (Cape Fear River surface water). Bald Head Island also has a groundwater treatment facility and supplements their water supply from Brunswick County.
