Florida Well Water Problems

Florida Well Water Diagnostics

Diagnose sulfur smell, iron staining, pump problems & contamination — with FL-specific treatment costs and DEP regulations. 1M+ FL private wells; Floridan Aquifer issues; FL DEP 62-532 compliant.

FL Well Regulations Overview (Ch. 62-532 FAC)

FL Department of Environmental Protection governs water well construction, repair, and abandonment under Chapter 62-532, Florida Administrative Code. - All water wells must be constructed by a licensed FL water well contractor (Rule 62-531) — not the same as a plumbing license; verify separately at myfloridalicense.com. - Wells must be permitted through your county or regional Water Management District (SFWMD, SJRWMD, SWFWMD, NWFWMD). - Abandoned wells must be properly plugged by a licensed contractor — unplugged abandoned wells are a major contamination risk in FL's shallow aquifer. - FL DEP recommends annual testing for all private well owners. - Well setback requirements: minimum 75 feet from septic tank, 200 feet from drain field, 50 feet from property line with dwelling. - After any flood event or hurricane, FL DEP may issue county-level well advisories requiring testing before resumption of use.

Recommended FL Well Testing Panel

Order from a FL DEP-certified lab (mail-in kits $40–$150 for full panel). FL County Health Departments often offer low-cost testing.

Post-Hurricane Well Protocol — Required After FL Flooding

After any major FL hurricane bringing flooding near your well (Irma, Ian, Milton, etc.), assume the water is contaminated until tested. 1) Do NOT drink, cook, or brush teeth with well water — use bottled water immediately. 2) Order emergency coliform/E. coli test from a FL DEP-certified lab ($30–$60) — results in 24–48 hours. 3) Shock chlorinate the well — call a licensed FL well contractor ($150–$350). 4) Re-test 2–3 days after shock chlorination before resuming normal use. Floodwater can enter through the casing, grout annulus, or vent cap, introducing surface bacteria (E. coli, coliform). Even wells with no visible damage may test positive.

FL Well System Lifespan Guide

FL conditions (sand, iron, sulfur, heat) accelerate wear: Submersible pump 10–15 yrs (normal); 7–12 yrs (high iron/sand aquifer). Pressure tank bladder 5–12 yrs. Well casing & screen 25–50+ yrs (can fail earlier in corrosive aquifer). Sediment pre-filter 1–3 yrs. UV sterilizer bulb 1 yr. Sand warning: if you see sand in your water, the pump screen has likely failed — act quickly to avoid total pump failure.

Treatment Decision Tool

Sulfur / H₂S Only: Aeration system (most effective, chemical-free) $800–$2,000; activated carbon filter (low-level H₂S) $500–$1,500; chlorination injection (moderate-high) $1,500–$3,000; shock chlorination (first step) $150–$350. FL quick fix: if the smell is only in hot water, replace the water heater's magnesium anode rod with an aluminum/zinc rod ($20 DIY).

Iron + Sulfur — most common FL well combination: Floridan Aquifer typically produces iron (1–10 mg/L) and H₂S together. Air injection oxidizing filter $2,000–$4,000; manganese greensand filter $2,000–$5,000; chemical injection + filter (iron bacteria) $2,000–$4,500; Birm filter (ferrous iron, low H₂S) $1,500–$3,000. Test to identify iron type (ferrous, ferric, or iron bacteria) before buying.

Hard Water / Scale (Floridan Aquifer 200–400+ ppm): Salt-based softener (>300 ppm) $1,200–$2,500 (salt $20–$40/mo); salt-free TAC (150–300 ppm) $1,500–$3,500; RO drinking water only $400–$1,200 (does not protect appliances). Alachua, Marion, and North-Central FL often see 300–500+ ppm.

Bacterial Contamination: If active contamination, do not drink; order coliform/E. coli test and use bottled water. UV sterilizer (gold standard) $400–$1,200 (bulb $80–$150/yr); shock chlorination $150–$350; chlorine injection $1,500–$3,000. UV only works on clear water — remove iron/turbidity/color first; install UV after all filtration.

Low pH / Corrosive Water: Low pH leaches copper (EPA action level 1.3 mg/L). Calcite neutralizer (pH 6.0–6.8) $1,200–$2,000; soda ash injection (pH < 6.0) $1,500–$2,500; calcite/Corosex blend $1,200–$2,200. Prone areas: North FL (Alachua, Columbia, Marion), shallow sandy aquifer. Blue-green stains are the telltale sign.

Complete FL Well Water System — Typical Rural Build-Out

Layered system, each stage protects the next: 1) Sediment Pre-Filter (5–20 micron) $200–$400. 2) Iron/H₂S Treatment (air injection oxidizing or manganese greensand) $2,000–$4,500. 3) Water Softener or TAC $1,200–$3,500. 4) UV Sterilizer (after filtration) $400–$1,200. 5) Under-Sink RO (final drinking water polishing) $400–$1,200. Total installed (typical FL rural home): $4,200–$10,800. Always test water before purchasing; a licensed FL contractor should pull samples and size the system.

Finding a Licensed FL Well Contractor

FL water well contractors must be licensed under Rule 62-531 FAC — separate from a plumbing license. Verification checklist: licensed FL Water Well Contractor (Rule 62-531)? Will pull required county well permit? Can provide original drilling log (well completion report)? What water test recommended before proposing treatment? Performance guarantee on installed systems? System sized for actual household flow rate? Insured for well contractor liability? Red flag: any contractor who recommends a treatment system without first testing your water.
