Aquifer-Sourced Reverse Osmosis Water Treatment Plant
SOURCE TO STREAM, CLEAN, CONTAMINANT FREE DRINKING WATER
2023 - NO RATE INCREASE!
The H2GO water lines have been flushed. There are a few dead-end lines still to be flushed, however, this is part of regular distribution system maintenance. If you’ve been waiting for the system flushing to end, there’s no longer a need to continue with your contracted outside water service.
The State requires public water systems to include disinfectant in the treatment of potable water. Chlorine residual in the finished water leaving the RO plant is roughly at 0.80 ppm, and in the furthest reaches of the H2GO distribution system the chlorine residual is about 0.2 to 0.3 ppm. For reference, 0.20 ppm chlorine residual is the lowest residual required and 4.00 ppm is the highest residual allowed per the State.
Some customers have reported noticeable chlorine taste in the water, this is to be expected after drinking bottled water for an extended period of time. If the chlorine odor or taste is bothersome, refrigerator filters and Brita type filters do reduce odor and taste of chlorine in drinking water.
There are numerous water softener/filtration providers scaring consumers into unnecessary purchases.
Here is some helpful information:
The water leaving the RO plant has a pH anywhere from 7.4 - 7.8.
Alkalinity is roughly 75.
Average hardness for the month of October 2023 - 72 mg/L CaCO3 (ppm).
TDS (total dissolved solids) Tests
TDS (total dissolved solids) tests are being used by softener/filtration providers and consumers to measure water quality. A TDS test is not a reliable water quality test.
The TDS test provides a whole number, with no indication of what the number represents. Electrolytes increase TDS, good minerals increase TDS.
Our water treatment process includes adding calcium carbonate, which adjusts the pH, hardness, and alkalinity, increasing the TDS count. The State required addition of disinfectant in a public water distribution system also affects the TDS whole number.
H2GO’S Water Supply - Clean and Free of Industrial Contaminants!
Distribution System Free of Industrial Contaminants
WATER TEST RESULTS
(June 21, 2023)
On May 30th, 2023, Brunswick Regional Water and Sewer turned on the Reverse Osmosis Water Treatment Plant pumping water sourced exclusively from contaminant free aquifers 400’ – 600’ deep, already confirmed with non-detect levels of manmade contaminants.
On June 5th, 2023 water samples were pulled from numerous locations within the H2GO distribution system to be tested for 40 different PFAS analytes.
The Board of Commissioners’ meeting held June 21st included approval of the 2023-2024 budget, which presented NO RATE INCREASE!
H2GO’s distribution system Flushing Program is still underway, expected to last another four to six weeks, possibly longer if needed. The flushing program consists of opening fire hydrants and water line dead ends; it does not include the addition of any chemicals. “Line flushing is a routine distribution maintenance task, which is essential to maintaining a healthy distribution system. The current aggressive transitional flushing program will be followed by routine flushing as needed. H2GO will notify the public when the current flushing program is complete,” noted Stephanie Blair, Communications Director at H2GO.
Update - 5/25/23
LELAND, NC – H2GO’s Aquifer-Sourced Reverse Osmosis Water Treatment Plant will begin pumping aquifer-sourced RO treated water into the distribution system on Tuesday, May 30th.
While new reverse osmosis treated water supplies are pumped into the water distribution system, H2GO crews will be conducting an aggressive and robust flushing program. Flushing of the water lines is necessary to purge the distribution system of existing water that contains chloramine disinfectants and unregulated contaminants; scour pipes to remove biofilms, organic and mineral deposits; and to restore the health of the water distribution system. The disinfectant used in the water supplies will be permanently changed from the County’s chloramines to chlorine as part of H2GO new RO treatment process.
Customers may experience fluctuations in water pressure, and may taste, see, and smell a noticeable decline in water quality during the flushing program. The flushing program may take weeks or longer as the crews flush nearly 200 miles of H2GO’s water distribution system pipes. “As we transition from County water supplies to H2GO’s reverse osmosis water, the flushing program will likely cause pressure fluctuations and temporary water quality issues. This is to be expected. We ask customers to please be patient as we work to return the water distribution system to normal operations,” noted Bob Walker, Executive Director at H2GO. During the flushing process, public water supplies will continue to meet all regulatory requirements.
When the flushing program is complete, H2GO public water supplies will be free of harmful contaminants such as 1,4 Dioxane, GenX and other per-fluorinated compounds. H2GO’s Reverse Osmosis treated public water supplies will be of the highest quality.
On June 5th H2GO will pull multiple water samples from the distribution system and send them to an outside laboratory requesting expedited test results. H2GO will test for 40 different PFAS analytes, and will notify the public as soon as test results verify “non-detected” levels of the PFAS analytes in the distribution system.
“Our team has eagerly anticipated this day, and we know our customers have as well. Providing a new water source to our district is a crucial step in the right direction for our growing community. H2GO’s staff and commissioners are truly grateful for the tremendous support we’ve received throughout this major undertaking. Our team is committed to providing the highest levels of water and sanitary sewer services,” said Stephanie Blair, Communications Director at H2GO.

From the three remaining bidders, Harn RO Systems of Venice, Florida won the contract for $1,714,000. This put H2GO $650,000 under budget thus far.
May 8, 2017:
The North Carolina Department of Environmental Quality issued a National Pollution Discharge Elimination System permit to discharge brine wastewater into the Brunswick River from the plant. “Based on the review of the public record, written and oral public comments, the North Carolina General Statutes and Administrative Code, and discussions with other Division of Water Resources (DWR) staff, I recommend to the Division Director that the draft NPDES permit for the Brunswick Regional Water and Sewer H2GO Water Treatment Plant be modified and issued…”. The primary permit modification includes a provision to implement a one-year supplemental monitoring program, to be coordinated with the UNCW Center for Marine Science, to verify mixing and dilution predictions established to ensure environmental protection of the river.
The Wooten Company finalized the PER detailing existing water supplies, future conditions, project alternatives, recommended plan, and plan implementation and Raftelis Financial Consultants prepared an updated Economic Feasibility Study for the proposed Reverse Osmosis Water Treatment Plant based on probably construction costs, detailed O&M costs, water to be produced, escalation factors, growth assumptions, and future capital improvements.
October 2015-January 2016:
RO pilot plant testing will be performed for a 90-day period. Using water from the newly constructed production wells, the pilot plant was operated 24/7 to analyze key operating parameters (e.g.., membrane flux, permeate recovery and quality, concentrate quality and flow, pre and post treatment chemical dosing, operating pressures, etc.).
June 2015-October 2015:
Two (2) production wells were recently installed at the proposed RO plant site: one 12” well was installed 400’ deep into the Lower Peedee aquifer and one 12” well was installed 600’ deep into the Black Creek aquifer. Pump testing performed to-date indicates better performance rates than from the test wells and preliminary sampling indicates better water quality than from the test wells.
October 2013-July 2015:
Based on the North Carolina State Environmental Policy Act (SEPA), a comprehensive Environmental Assessment (EA) for the proposed RO project was developed.
October 2013-February 2014:
Brackish concentrate, or reject water from RO plant operations are proposed to be discharged to the Brunswick River. CORMIX is an expert rule-based system for the analysis, prediction, and design of discharges into water bodies, i.e.., the Brunswick River. Based on the receiving stream characteristics obtained from field investigations, and concentrate water chemistry, CORMIX predicts mixing and plume characteristics from the proposed outfall.
March 2013-August 2013:
Based on the Water Supply Feasibility Study, H2GO commissioned Raftelis Financial Consultants to prepare a Feasibility Analysis to evaluate the economic feasibility of building a new RO water treatment plant versus continuing to purchase wholesale water from BrunsCo PU. The analysis focused on three primary measures: 1) differences in projected annual costs and expected impacts on rates and customers; 2) Net Present Value (NPV) of total costs over a 20-year planning period; and 3) reserves generated from targeted debt coverage.
May 2012-June 2013:
Under GMA’s guidance, H2GO installed 4 test wells - two wells at our elevated water tank site, and two wells on Trade Street. These locations were selected to provide a hydrogeologic cross section from southeast to northwest through H2GO’s service area. At each test well site, one 4” well was installed 400’ deep into the Lower Peedee aquifer and one 4” well was installed 600’ deep into the Black Creek aquifer. Pump tests were performed and water samples were analyzed from each well at each site.
April 2012-August 2013:
H2GO evaluated each RO plant, comparing treatment capacities; water source and supply characteristics; pre-treatment and post-treatment operations; permeate recovery rates; concentrate characteristics and outfall locations; operation and maintenance costs; and facility location in relationship to their community. The H2GO Board, Leland Town Council, Belville Commissioners and staff toured RO plants in NC and discussed with their administrators and plant operators the advantages of RO treatment.
The Water Supply Feasibility Study was completed and determined that no additional supply allocations from LCFW&SA were available to pursue surface water supplies and treatment; that sustainable and treatable groundwater supplies from the Lower Peedee and the Black Creek aquifers underlie the H2GO service area; and that preliminary cost comparisons indicate brackish groundwater supplies with RO treatment are favorable over continued purchase of wholesale water from BrunsCo PU.
H2GO commissioned a Water Supply Feasibility Study to evaluate alternative water supplies to meet future needs based on anticipated future service areas and customer growth over a 20-year planning period. This study evaluated the feasibility of 1) obtaining surface water (Cape Fear River) supplies from the LCFW&SA with a new surface water treatment plant; 2) the feasibility of developing groundwater supplies for treatment in a new reverse osmosis (RO) treatment plant; and 3) comparing those cost estimates to continued purchase of finished water from BrunsCo PU. As part of the alternative water supply evaluations, Groundwater Management Associates (GMA) performed a Hydrogeologic Framework Study and Preliminary Well field Evaluation to target aquifers for future exploration that have potential to provide sustainable and treatable brackish groundwater supplies for an RO treatment plant.
