Introduction
Pender County’s coastal location and rapid growth have stressed the local water system. Residents of Hampstead and nearby communities routinely share photographs of yellow, brown, or rusty water on social media and complain of foul smells and metallic or “swampy” tastes.
Some neighborhoods installed private wells during the county’s recent expansion, but new sources have occasionally produced an unpleasant sulfide odor despite meeting regulatory standards.
Reports of discolored water have led homeowners to install under-sink filtration and reverse osmosis (RO) systems, flush their pipes frequently, and even rely on bottled water – like we do here at Topsail Guide.
This guide summarises the history of those complaints, explains what county officials have done, examines possible health impacts, and recommends professional and do-it-yourself solutions.
Historical reports of water problems
Hampstead residents have been voicing concerns about water quality for years. In the WyndWater community, for example, homeowners reported muddy or yellowish-brown water flowing from taps and discolored bathwater.
According to local news, Pender County Utilities routinely flushed the pipes, yet the discolored water returned. When asked, one resident noted that her tap water tasted awful and looked yellowish-brown when filling up a tub.
Another homeowner said the water destroyed appliances, requiring her to run vinegar through the dishwasher because everything came out filmy and gross. Many residents now buy bottled water for cooking and drinking, sometimes spending more than $100 per month.
Elsewhere in the county, brown or discolored water has also drawn attention. Residents of the Emerald Ridge subdivision told reporters that rust-colored water ruined their laundry and appliances and that their concerns were being ignored.
In summer 2024 a petition in Hampstead demanded action on brown water and complained that problems were not being addressed despite a recent rate increase from Pender County Utilities. Other complaints have focused on unpleasant sulfide odors after new county wells came online.
These persistent issues have undermined trust in the public water system and led many families to seek their own solutions.
County responses and known issues
Pender County officials have acknowledged water quality complaints and have tried to offer some explanations.
Routine flushing of hydrants stirs up sediment in the pipes, temporarily causing cloudy or rusty water and reduced pressure; the county advises residents to run cold water until it clears and avoid doing laundry during flushing.
In June 2024, a boil water advisory was issued for customers experiencing low pressure or discolored water between the south end of Sloop Point Loop Road and Surf City. The advisory was lifted after testing showed no bacteria was present, however.
Pender County Utilities emphasised that such advisories are precautionary and should not be interpreted as evidence of contamination.
A water advisory in the WyndWater community warned that haloacetic acids (HAAs) were elevated due to chlorine reacting with organic matter and could be unsafe for pregnant women or people with compromised immune systems.
Pender County officials explained that hydraulic fluctuations between the Hampstead and Topsail water towers, combined with slightly elevated iron levels and the relocation of a water main, reduced turnover and allowed disinfection by-products to build up.
To address the problem, Pender County hired an engineering firm to evaluate the Highway 17 water corridor and implemented a new operational strategy combining water quality monitoring and extensive flushing.
The county has also invested in treatment technology to remove emerging contaminants.
Pender County Utilities uses granular activated carbon (GAC) filters to reduce per- and polyfluoroalkyl substances (PFAS) from the Cape Fear River supply and plans to add a membrane filtration plant by 2028.
Tests show that the existing GAC system reduces PFOA, PFOS and GenX to levels far below the U.S. Environmental Protection Agency’s maximum contaminant levels. A county fact sheet notes that quarterly testing found no PFAS in well water and that the EPA’s final drinking-water standards for PFOA and PFOS are 4 parts per trillion, with 10 parts per trillion limits for other PFAS. Although regulators consider Pender County’s water safe, the presence of disinfection by-products, sediment and occasional odor continues to prompt resident concern.
Impact of using tap water
Drinking discolored or odorous water can be unpleasant, but health risks depend on the contaminants present. Elevated iron and manganese cause reddish-brown or black water but generally pose little health risk; iron in water contributes only a small fraction of daily intake, while excessive manganese exposure may affect children’s development and cause neurological symptoms.
Disinfection by-products such as haloacetic acids form when chlorine reacts with organic material. Although Pender County’s HAA levels are below the federal limit of 60 parts per billion, they exceed the cautious health guideline published by some advocacy groups. The WyndWater advisory warned that elevated HAA levels could be unsafe for pregnant women or those with compromised immune systems.
PFAS and other emerging contaminants have been detected at low levels in surface water supplies. The county’s GAC system reduces PFAS to below current regulatory limits, yet PFAS chemicals persist in the environment and are linked to cancer, immune suppression and hormonal disruption.
Manganese, another naturally occurring metal, can cause developmental problems in children at high concentrations. Although local tap water meets state and federal standards, residents with vulnerable health—pregnant women, infants and people with weakened immune systems—may want additional filtration or to follow boil water advisories when issued.
Boil water advisories typically mean that the system experienced low pressure, a pipe break or maintenance that could allow pathogens to enter. Residents should boil water for at least one minute (three minutes at higher elevations) before drinking or cooking and avoid using ice made during the advisory. Once tests confirm the absence of bacteria, the county lifts the advisory.
How locals have addressed the problem
The most common local response has been to install reverse osmosis systems or other point-of-use filters.
In households affected by discolored water, residents frequently use under-sink RO units for cooking and drinking, while using tap water for other purposes. Some families flush their pipes regularly, run cold water during hydrant flushing and clean faucet aerators to remove sediment. Others have banded together to petition county commissioners for infrastructure improvements and rate relief.
Experts caution that taste and smell are not reliable indicators of safety and recommend testing the water before choosing a filtration device. The Centers for Disease Control and Prevention advises residents to review their utility’s water quality report and consider third-party certified filters for contaminants of concern. Water filters with activated carbon can reduce chemicals and improve taste, but most household filters do not remove germs. Testing helps determine whether additional treatment, such as RO or ultraviolet disinfection, is necessary.

Choosing and installing DIY reverse osmosis systems
Many homeowners choose to install their own reverse osmosis systems. A point-of-use RO unit mounts under a sink and connects to the cold-water supply, an air-gap faucet and the drain.
Basic kits include a sediment prefilter, activated carbon filters, a semi-permeable membrane and often a post-filter or remineralisation stage. Well-known models such as the iSpring RCC7 (five stage), iSpring RCC7AK (six stage with alkaline filter), APEC ROES-50 and Home Master TMHP remove a wide range of contaminants, produce 50–75 gallons per day and cost roughly $150–$500 depending on features.
Installation requires basic plumbing skills: shutting off the water, drilling a hole for the dedicated faucet if one is not available, connecting tubing and fittings and attaching a drain saddle. Homeowners familiar with plumbing can install an RO system themselves, though relocating a drain or supply line may require a professional plumber. Costs vary widely—a point-of-use system can cost as little as $150, while a whole-home RO system may exceed $4,800. Because RO water has very low total dissolved solids, it can leach copper from pipes; using PEX or non-metallic plumbing materials prevents copper contamination.
Efficiency is another consideration. Standard RO units can waste five or more gallons of water for each gallon produced. The U.S. Environmental Protection Agency’s WaterSense program certifies systems that send only 2.3 or fewer gallons of waste down the drain per gallon produced and recommends such units for households concerned about conservation. WaterSense notes that RO may not be necessary for every situation and that other filtration technologies, such as activated carbon or ion exchange, can remove many contaminants without wasting water.
To complete a DIY installation you will need adjustable wrenches, Teflon tape, a drill with a hole saw for the faucet, tubing cutters and the willingness to work under a sink.
Follow the manufacturer’s manual and watch installation videos if available. After installation, flush the system thoroughly and replace filters on the recommended schedule.
Conclusion
Water quality issues in Pender County arise from a combination of aging infrastructure, naturally occurring minerals and disinfection by-products. While county testing shows that tap water meets federal and state standards, residents in Hampstead continue to experience discolored water, odors and taste problems. Routine flushing stirs up sediment, and advisories may be issued when pressure drops or disinfection by-products rise. Residents should stay informed through county announcements, run cold water when flushing occurs and follow boil water advisories.
For those seeking peace of mind, under-sink reverse osmosis systems and whole-house filters provide an extra barrier against contaminants. DIY installation is possible for handy homeowners, but professionals can ensure proper sizing and connections.
Regardless of the approach, testing the water first and selecting certified equipment will help households in Hampstead enjoy cleaner, better-tasting water.
