About Well Water Testing in Florence

Well water testing analyzes your private well water for contaminants including bacteria, nitrates, heavy metals, pH levels, and other substances that can affect health and taste. The EPA does not regulate private wells — the responsibility falls entirely on the homeowner. An estimated 23% of private wells have at least one contaminant exceeding health-based standards according to the USGS. Annual testing is recommended at minimum, with additional testing after flooding, nearby land use changes, or if you notice changes in taste, color, or odor. Basic tests cover coliform bacteria and nitrates — the two most common and dangerous contaminants in well water. Comprehensive panels add testing for lead, arsenic, manganese, iron, hardness, pH, total dissolved solids, volatile organic compounds, and pesticides depending on your region and local geology. Results typically take 5-14 business days from a certified laboratory. If contaminants are found, treatment options range from simple point-of-use filters to whole-house treatment systems depending on what is detected and at what concentration.

What Florence Homeowners Should Know

Local Soil Conditions: Florence County soils are dominated by Goldsboro sandy loam, Norfolk sandy loam, and Lynchburg sandy loam — Ultisols (Hapludults and Paleudults) formed in loamy Coastal Plain sediments of the Upper Coastal Plain. The Goldsboro series is a moderately well-drained Aquic Paleudult with a sandy loam surface transitioning to a sandy clay loam Bt horizon at 8–20 inches — percolation rates of 0.5–1.5 inches per hour, suitable for conventional systems. Norfolk sandy loam on well-drained uplands has a friable sandy clay loam Bt with moderate permeability. Lynchburg soils in the interstream flats are poorly drained with seasonal high water tables at 12–24 inches. The Great Pee Dee River floodplain adds Chastain and Altavista soils.

Water Table: Florence County's Upper Coastal Plain setting provides generally good drainage on upland positions: Norfolk and Goldsboro series maintain water tables at 3–6 feet. Poorly drained interstream flats (Lynchburg and Rains soils) have seasonal high water tables at 12–24 inches. DHEC requires adequate seasonal high water table separation demonstrated by a Licensed Soil Classifier.

Climate Impact: Florence has a humid subtropical climate with hot, humid summers and mild winters. Annual rainfall averages 46 inches, distributed through the year with summer afternoon thunderstorms. Hurricane Florence (2018) caused catastrophic flooding in the Pee Dee region — including record flooding of the Great Pee Dee River — damaging numerous septic systems across Florence County. The region's agriculture-dominant landscape creates seasonal patterns in surface water and soil moisture.

Signs You Need Well Water Testing

  • Annual testing is overdue — all private wells should be tested at least yearly
  • Water has a new or unusual taste, odor, or color
  • Recent flooding or heavy rainfall near the well
  • Nearby construction, agriculture, or land use changes
  • Household members experiencing unexplained gastrointestinal illness
  • Buying or selling a property with a private well

The Well Water Testing Process

  1. 1 Contact a certified water testing laboratory or local health department for test kits
  2. 2 Collect water samples following the lab's instructions for each test type
  3. 3 Submit samples to the lab within the required holding time (usually 24-48 hours)
  4. 4 Lab analyzes samples and compares results to EPA health-based standards
  5. 5 Receive a detailed report showing contaminant levels and whether they exceed guidelines
  6. 6 If issues are found, consult with a water treatment professional for remediation options

Frequently Asked Questions — Florence

Were Florence County septic systems damaged by Hurricane Florence in 2018?
Hurricane Florence (2018) caused record flooding of the Great Pee Dee River and its tributaries throughout Florence County. Properties in flood-prone areas, particularly near the river and in poorly drained interstream flat positions, had their septic systems inundated with floodwater. Flooding can introduce silt into drainfield trenches, damage tank components, and temporarily or permanently reduce absorption capacity. If your property flooded during Hurricane Florence and you have not had a post-flood inspection, consider having a licensed contractor evaluate your system.
Are septic systems common throughout Florence County?
Yes — outside of Florence city and the Town of Lake City, virtually all of Florence County's rural residential development relies on septic systems. The county's townships (Pamplico, Johnsonville, Timmonsville, Effingham) are predominantly septic-served. Rural residential lots on former agricultural land commonly have systems installed in the 1970s–1990s that are approaching or past their design life.
How much does septic installation cost in Florence County?
Conventional gravity systems on suitable Norfolk or Goldsboro series sites in Florence County range $4,500–$7,500. Engineered alternatives for poorly drained Lynchburg or floodplain-adjacent sites run $8,000–$13,000. Florence County's rural market and relatively straightforward soil conditions on upland sites keep prices competitive.
What should I know about buying a rural Florence County property with a septic system?
Request all available DHEC permit records for the system — Florence County DHEC maintains records of all permitted installations. Have a licensed contractor pump the tank, inspect baffles, and probe the drainfield before closing. Pay particular attention to the drainfield's landscape position: systems placed in lower Lynchburg soil positions may experience seasonal saturation stress even when they were correctly installed. Flood history for the property (particularly Hurricane Florence 2018) is worth investigating.
Does SC DHEC require a septic inspection when selling a home in Florence County?
South Carolina does not require a formal DHEC-conducted septic inspection at real estate transfer, but DHEC maintains permit and inspection records that buyers can request. Buyers are strongly advised to hire a licensed inspector. Real estate transactions in Florence County regularly include septic inspection contingencies, particularly for older rural properties.
