North Carolina well water questions, answered.

Check the breaker for the well pump in your electrical panel. If it has tripped, reset it once. If it trips again, leave it off and call (704) 933-9040.

A breaker that trips twice is telling you something is wrong with the pump, its wiring or the control. Don’t keep resetting it, and never open the pressure switch, the pump control box or the wellhead wiring: they’re live at 240 volts. Also check whether the pressure gauge on the tank reads zero, and tell them what you see when you call.

Pressure that keeps dropping, air spitting from faucets, sand or sediment in the water, new noises, changes in the water, and a power bill rising for no reason are the common signs.

Their own advice is that pumps rarely quit all at once unless something like a switch blows; most decline slowly. Catching it early can mean a repair instead of an emergency replacement.

Low pressure on a well usually comes from a worn pump, a pressure switch set low or failing, a waterlogged pressure tank, a clogged filter, or a well that can’t keep up with demand.

Start with the easy one: if you have a sediment filter, check whether it’s clogged. Beyond that, the fix depends on finding which part is at fault, so the right diagnosis saves money.

Many submersible well pumps run 10 years or more, but life depends heavily on how often the pump starts, the water and the power supply.

Short cycling from a bad pressure tank, sand from the well, running the well low and poor voltage all shorten pump life. Fixing those when the pump is replaced matters as much as the new pump.

Air in the lines usually means the water level is dropping close to the pump intake, a leak in the drop pipe or check valve is letting air in, or the pump is starting to fail.

If it happens mostly after heavy use (laundry, irrigation) and clears up, the well may be drawing down. If it’s constant, there’s likely a leak or worn part. Either way it’s worth a call before the pump runs dry.

It isn’t a job to take on yourself. Pulling and setting a well pump means 240-volt wiring and a long string of heavy pipe hanging in an open well, and in North Carolina it’s regulated well contractor work.

Contractors who install pumps or break a well seal must hold state certification. A dropped pump or a poorly resealed well cap can also contaminate or ruin the well. Leave it to a certified contractor.

A pressure tank stores water under air pressure so your pump doesn’t have to start every time someone opens a tap.

Inside most modern tanks, a rubber bladder or diaphragm separates water from a cushion of air. As you use water the air pushes it out; when pressure falls to the cut-in setting, the pump starts and refills the tank.

Short cycling is a pump turning on and off every few seconds. It’s hard on the motor and is one of the most common reasons well pumps fail early.

Usually it means the pressure tank has lost its air charge or its bladder has failed, so there’s no cushion. A clicking pressure switch and a gauge needle bouncing quickly up and down are the giveaways.

Bladder pressure tanks commonly last somewhere around 5 to 15 years, depending on the tank, the water and how hard the system works.

Rust at the bottom, water from the air valve on top, or a tank that sounds full of water when you knock high on its side are signs it’s near the end.

Many homes run with a pressure switch set around 30/50 or 40/60 psi: the pump starts at the lower number and stops at the higher one.

The tank’s air charge has to match the switch setting, typically a couple of psi below the cut-in pressure, checked with the system drained. Adjusting the switch means working near live terminals, so it’s a job for the pump technician.

Turn off the pump’s breaker and call. A switch that clicks without starting the pump can mean burned switch contacts, a failed control box or a pump motor problem.

Don’t tap or pry the switch to get it going: it’s live at 240 volts.

Most drilled household wells in this part of the North Carolina Piedmont are a few hundred feet deep, but there’s no fixed number: the well goes as deep as it takes to cross enough water-bearing fractures.

The driller cases through the red clay and weathered rock, seals the casing into solid rock, then drills on, watching the cuttings and the water coming up. Some wells find plenty within a couple hundred feet; others need more.

From cracks in the bedrock. The red clay and the soft, weathered rock beneath it (saprolite) soak up rain and feed water slowly down into fractures in the hard rock, and the well draws from those fractures.

That’s why a well is cased and sealed through the clay: the casing keeps surface water and loose material out while the open hole in the rock collects water from the fractures.

In fractured rock, water is wherever the cracks are, and two wells a few hundred feet apart can cross completely different fractures.

Rock type matters too: granite-type rock around Kannapolis and the Slate Belt rock to the east break differently. Local drilling experience helps, but no driller can promise a depth before drilling.

Depth is the biggest factor, followed by how much casing is needed to reach solid rock, the pump and tank, the distance to the house, and county permit fees.

Because depth isn’t known until the well is drilled, quotes are usually based on per-foot drilling and casing plus the pump system. Ask what’s included: permit, grout, well cap, pump, tank, wiring and the line to the house.

Yes. North Carolina law requires a permit from the county health department before a private well is built, repaired or abandoned.

The county evaluates the site, checks setbacks from septic systems, property lines and buildings, inspects construction, and samples the water once the well is completed. Each county sets its own fee.

The drilling itself often takes a day or two; the whole job takes longer because of the county permit, the pump installation and the required water test.

Drilling time depends on depth and rock. Setting the pump, tank and line to the house comes after, and the county samples a new drinking-water well after it’s completed.

If you water a big lawn or garden, often yes. A separate irrigation well keeps sprinklers from wearing out your household pump and drawing down your drinking-water well, and keeps irrigation off the city meter.

Irrigation wells still need a county permit and must meet setbacks. The well and pump are sized to the zones they have to run.

At least once a year for bacteria, and any time the water changes in color, taste or smell, after a flood, or after well repairs.

Wright Well & Pump and the National Ground Water Association both recommend having a well tested and maintained at least once a year. Test for arsenic, radon and the full mineral panel at least once, and again if anything changes.

In some areas, yes. North Carolina research has found arsenic above the federal drinking-water standard more often in wells drilled into the Carolina Slate Belt, which runs through Union and Stanly counties and the eastern edges of Cabarrus and Rowan.

University of North Carolina researchers identified Stanly and Union counties for targeted monitoring. Most wells still test fine. Arsenic has no taste, color or smell, so only a lab test can tell you.

Radon is common in Piedmont well water, especially in wells drilled into granite; uranium above the drinking-water limit shows up in a small share of wells.

State studies found most private wells in the Piedmont and mountains carry radon above the proposed 300 pCi/L level, with the highest levels in granite. Radon in water escapes into indoor air when water runs. Test for both if you’re in a granite area; treatment is available if levels are high.

Orange, red or brown stains almost always mean iron; black or dark stains often mean manganese. Both are common in Piedmont groundwater.

They’re mainly a nuisance (stains, taste, clogged fixtures) rather than a health issue at typical levels, but a test should confirm the levels and pH before choosing a filter, because the right treatment depends on both.

Water with a pH below about 7 is acidic. Much Piedmont well water is slightly acidic, and over time it can corrode copper pipes, cause blue-green stains, and pick up metals from plumbing.

A neutralizing filter raises the pH. Pinhole leaks in copper and blue-green stains in sinks are common clues. A test for pH, copper and lead tells you whether it’s needed.

Don’t drink it until it has been tested. Use bottled water in the meantime and contact your county health department about testing.

Sudden changes can come from a broken well cap, a cracked casing, surface water getting in after heavy rain, or a failing pump. Call to have the well checked as well.

Shock chlorination disinfects a well and plumbing with a strong chlorine solution to kill bacteria, usually after a positive bacteria test, a repair or a flood.

In North Carolina, disinfecting a well is covered by well contractor certification. It should be followed by a retest a while later, and it doesn’t fix the cause if surface water is getting into the well, so the wellhead and casing need checking too.

It can, especially if it’s a low-yield or shallower well. Deep wells in fractured rock usually hold up better, but long droughts lower water levels across the Piedmont.

If a well struggles in dry summers, the cause might be the pump setting, the yield of the well or rising household use. Options include lowering the pump, adding storage, spreading out heavy use, deepening, or a new well.

Seal the well house so you can’t see daylight through it, insulate the pipes and the tank, and use safe heat inside the well house in hard cold.

That’s their own winter advice: walk around the well house looking for cracks and gaps, wrap pipes in heat tape or insulation, insulate the tank and the inside of the well house, and if you use a heat lamp or heater, keep anything that could catch fire well away from it. They’ll come out and prepare the well for you if you’d rather.

Look at the well cover and well house for damage from wind and falling limbs, and watch for any change in your water. If the well was flooded or the water changed, don’t drink it until it’s tested.

After Hurricane Florence they reminded customers that storms can damage well coverings and the pump inside them. If anything looks broken or different, call to have it checked.

Don’t drink the water or use it for cooking until it has been disinfected and tested. Use bottled water and follow your county health department’s guidance.

Floodwater can carry bacteria and chemicals into a well. If the pump or wiring was submerged, keep the breaker off until it has been checked.

Look the contractor up on the North Carolina Well Contractors Certification Commission’s list of certified well contractors, published by NC DHHS, and ask to see their wallet card.

The state list shows each contractor’s certification number, level, employer and date certified. Certified contractors carry a photo wallet card showing the dates their certification is valid. Danny Wright appears on that list as a Level A certified well contractor, certificate number 2021, certified since 1999.

Level A covers all well contractor work, including drilling wells. Level D covers installing pumps, breaking a well seal and disinfecting wells; Levels C and B add more construction and repair work in between.

Anyone who constructs, repairs or abandons a well, or installs a pump in one, must be certified at the right level by the North Carolina Well Contractors Certification Commission.

Yes. Since 2008, North Carolina has required the county health department to sample every newly built private drinking-water well, after the well’s certificate of completion, and have it tested by a certified lab.

The tests cover bacteria and a set of minerals and metals (such as arsenic, lead, iron, manganese and nitrate). After that first test, North Carolina has no routine testing requirement for private wells, so ongoing testing is up to you.

North Carolina sets minimum distances between a well and septic tanks, drain fields, property lines and buildings, and the county checks them when it permits the well. The exact distance depends on the type of well and the site.

That’s why a site evaluation comes before the permit. If you’re planning both a well and a septic system, sort out the locations together with the health department.

Have it properly abandoned (permanently sealed) by a certified well contractor, with a permit from the county health department.

An open or poorly capped old well is a direct path for contamination into the groundwater and a hazard to people and animals. Abandonment fills and seals it according to state rules.
