Nitrate In Drinking Water In Georgia
What residents of Georgia need to know about nitrate in drinking water — including how it enters water, which utilities have documented violations, and what steps to take.

Quick Answer
Is nitrate in drinking water a real concern in Georgia?
Yes — Georgia's poultry industry is the state's largest agricultural sector, and its coastal plain geology allows nitrate from animal waste and fertilizer to reach groundwater relatively quickly.
Is this mostly a public-water issue, a private-well issue, or both?
Primarily private well users in south Georgia agricultural counties; public water systems are monitored by Georgia EPD.
What is the main reason residents should care?
Poultry litter applied as fertilizer across Georgia's agricultural areas can leach nitrate into shallow groundwater, particularly in the coastal plain where soils are sandy and groundwater recharge is rapid.
Key Facts
| EPA Nitrate MCL | 10 mg/L as N |
| Georgia agriculture | Nation's leading poultry producer — poultry litter widely applied as fertilizer |
| Coastal plain geology | Sandy soils allow rapid nitrate percolation to shallow groundwater |
| Private well risk | South Georgia agricultural counties — test annually |
| State oversight | Georgia Environmental Protection Division (Georgia EPD) |
Why This Matters in Georgia
Georgia is the nation's leading poultry-producing state. Poultry litter — chicken and turkey waste — is widely applied as fertilizer across Georgia's agricultural lands. On the Coastal Plain (south and central Georgia), thin sandy soils provide little filtration before surface water reaches shallow groundwater, and private wells in these areas can accumulate nitrate from agricultural land application. Public water systems drawing from groundwater in these zones monitor nitrate under Georgia EPD oversight. Septic systems in rural communities also contribute nitrogen loading to groundwater.
Critical — Infants Under 6 Months
Do not use tap water that exceeds 10 mg/L nitrate-nitrogen to prepare infant formula or feed infants under six months. Boiling will concentrate nitrate — do not boil. Use bottled water or a certified reverse osmosis system (NSF/ANSI 58) until the issue is resolved.

How Nitrate Gets Into Drinking Water
Agricultural fertilizer and manure runoff
Nitrogen-based fertilizers and animal waste applied to Georgia cropland can leach into groundwater or run off into surface water supplies. This is the dominant nitrate pathway in most agricultural regions.
Septic system effluent
Failing or poorly sited septic systems release nitrogen-rich wastewater near drinking water wells. Rural areas with high well density and aging septic infrastructure face elevated risk.
Concentrated animal feeding operations (CAFOs)
Large livestock facilities generate significant waste. Lagoon leaks and overapplication of manure to nearby fields can create localized nitrate hotspots in groundwater.
Natural geological deposits
In some regions, naturally occurring nitrogen compounds in soil and bedrock contribute background nitrate levels to groundwater independent of agricultural activity.
Who Should Pay Closest Attention
Rural south Georgia residents on private wells, particularly in counties with intensive poultry operations, should test their water annually. Families with formula-fed infants face the highest acute risk from nitrate above the MCL.
Households with infants under six months
Pregnant residents
Private well owners in agricultural areas
Households near livestock operations or CAFOs
Rural residents on shallow groundwater wells
Households with older or failing septic systems nearby
How to Check Your Situation in Georgia
- 1
Identify your water utility. Use the ZIP lookup below or browse the Georgia utility directory on this site.
- 2
Read your utility's page on this site to see its current risk level and any open nitrate violations.
- 3
Review your utility's most recent Consumer Confidence Report (CCR) — mailed annually or available on the utility's website. It must disclose any MCL exceedances.
- 4
If you are on a private well, arrange testing at a Georgia Environmental Protection Division (Georgia EPD)-certified lab. Your state health department maintains a list of certified labs. Annual testing is recommended in agricultural areas.
- 5
If you have an infant under six months, use bottled water or a certified RO system (NSF/ANSI 58) immediately as a precautionary measure — do not wait for test results if you are in a high-risk area.
- 6
If your utility issues a nitrate exceedance notice, follow their guidance and do not use tap water for infants until the issue is resolved.
Treatment Options
Carbon filters and boiling do not remove nitrate. Only the options below are effective.
NSF/ANSI Standard 58 — Reverse Osmosis
RO systems certified to NSF/ANSI 58 reduce nitrate by 85–95% at the point of use. Under-sink installation required. The most practical residential option for nitrate concerns.
Distillation
Distillation units effectively remove nitrate along with most other dissolved contaminants. Suitable for drinking and cooking water — not whole-house use.
Anion Exchange
Ion exchange systems designed for nitrate removal exchange nitrate ions for chloride on a resin bed. Effective as a point-of-entry system; requires periodic regeneration and monitoring.
Carbon filters do NOT remove nitrate
Standard pitcher filters, faucet filters, and under-sink carbon units — including those certified NSF/ANSI 42 or 53 — do not remove nitrate. Do not use these for nitrate reduction.
