Quick answer: in Madison County, state law does not require a county repair permit to replace a well pump or tank, but new wells, repairs beyond the pump, and abandonments go through the Madison County Health Department's Environmental Health office in Marshall, which publishes its own well forms. If your well was flooded in 2024, it should have been disinfected and tested before use.
A river county with long drives
Madison County has about 22,500 residents spread across 11,874 housing units, far fewer than Buncombe or Henderson. Census data show the county's mean travel time to work is 32.7 minutes, the longest of the three counties we cover. For a well owner, it is worth planning around distance. Give the contractor clear directions to the wellhead, including whether the drive is steep or unpaved, so the first trip is not wasted.
Census data also show that 25.3 percent of Madison County residents are 65 or older and that 14.9 percent live in poverty. A pump replacement that costs $1,500 to $3,500 is a large expense for many households, so it helps to ask for an itemized estimate and to compare it with the published ranges in our cost guide.
What Helene did to Marshall and Hot Springs
The National Hurricane Center describes Madison and Yancey counties as having experienced devastating damage. Drone footage showed floodwaters from the French Broad River inundating the majority of buildings in downtown Marshall. Downstream, Hot Springs was devastated: the river destroyed numerous businesses and critical infrastructure, and water, sewer, electricity, and communication systems were heavily impacted. The French Broad at Hot Springs set a record crest, surpassing the Great Flood of 1916 by 0.3 feet. Four people died in Madison County, and hundreds of homes and buildings were destroyed or sustained major damage.
By May 2025, both towns had held reopening celebrations, though a Hot Springs recovery leader told the North Carolina Community Foundation that the town was not back to normal. Wells outside the towns can be affected too. A well that was submerged or damaged needs to be inspected, disinfected, and tested before use, according to the North Carolina Department of Health and Human Services.
Wells in a floodplain
Marshall and Hot Springs sit on the French Broad. N.C. State Extension explains that wells in river floodplain deposits can get high yields, but may draw from the stream if pumped hard, and surface water can carry contaminants a rock well would not. Flooding raises the same concern: floodwater that reaches the wellhead can carry bacteria into the well. A 2025 preliminary study of the French Broad River 15 days after the flood identified PFAS and other emerging organic contaminants in river water, which is another reason to treat flooded wells carefully and to ask your county health department what tests make sense.
Wells on the hillsides above the river face a different problem. The USGS says wells on hills and ridges yield, on average, about a third of what wells in draws and valleys do, so a ridge well that runs short may be a yield problem and not a pump problem. Read well pump replacement and well drilling for how contractors think about it.
Madison County well permits and forms
The Madison County Health Department's Environmental Health page lists four well-related documents:
- Application for Well Permit
- Application for Well Repair Permit
- Application for Well Abandonment Permit
- Water Sample Request Application
The office posts weekday hours of 8 a.m. to noon and 1 p.m. to 3:30 p.m., and accepts cash, checks, and credit or debit cards. A fee schedule is posted on the department's site. North Carolina law says the local health department must act on a well permit application within 30 days, or the permit is issued automatically. For pump or tank replacement alone, no repair permit is required, so those jobs do not wait on the county.
New wells in North Carolina must be sampled after construction, and the local health department collects the samples. The state tests for coliform bacteria and for metals including lead, arsenic, iron, manganese, and nitrate.
