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.

Brunswick County Stormwater Ordinance

Brunswick County Stormwater Ordinance

The stormwater ordinance became effective Sept. 16, 2002. The unincorporated areas of the county are subject to the ordinance. The county also has agreements in place to administer the Stormwater Ordinance in Belville, Boiling Spring Lakes, Bolivia, St. James and Sunset Beach.

The ordinance and accompanying Stormwater Management Manual outline how stormwater runoff must be addressed for all new development and redevelopment in the county.

A county Stormwater Permit is required for:

  • All non-residential new development.
  • Non-residential redevelopment that increases impervious surface on the site.
  • Residential development that disturbs greater than an acre.
  • Residential developments where the site will be graded, filled, or excavated and thereby change the elevation of a location by more than four inches.
  • Residential development or any related disturbance within 30 feet of the banks of a natural stream or water body.

Low Impact Development

In conjunction with the City of Wilmington, New Hanover County and the North Carolina Coastal Federation, Brunswick County developed a Low Impact Development (LID) Guidance Manual to encourage the use of innovative stormwater management techniques. A resolution along with the LID Guidance Manual was approved by the Brunswick County Board of Commissioners on November 3, 2008. A LID spreadsheet modeling tool to aid engineers, planners and developers with design and permitting the LID projects was also developed as part of the initiative.

For questions, contact Brigit Flora, PE, Stormwater Engineer.

Stormwater Drainage

The Stormwater Ordinance requires individual property owners to maintain all streams, creeks, ditches, swales, pipes, culverts, etc. that are on the private property. The county does not provide maintenance of drainage ways. (Article VI, Division III, Section 3.4)

Fences or walls shall not alter or impede the natural flow of water in any stream, creek, drainage swale or ditch. Drainage easements must be maintained and kept free of obstructions.

Other Agencies

The county does not control stormwater conveyance along North Carolina Department of Transportation roadways.

Development in Brunswick County is also subject to the North Carolina Coastal Stormwater regulations enforced by NC Department of Environment and Natural Resources (NCDENR). Other agency approvals may be required. Contact NCDENR to determine application regulations.
