What to know about Port Wentworth's water
Port Wentworth ranks #310 out of 378 cities in Georgia for water quality, placing it among the lowest-rated in the state.
Port Wentworth relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff.
Of particular concern: PFAS "forever chemical" levels exceed the 2024 EPA maximum contaminant levels. These synthetic compounds don't break down naturally and require specialized filtration such as reverse osmosis or granular activated carbon.
Hexavalent chromium (chromium-6) was detected at 0.11 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration.
While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection.
The system has seen 12 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

Do I need a water filter in Port Wentworth?
While lead levels are within EPA limits, a filter adds extra protection. PFAS compounds exceed EPA limits — a reverse osmosis or activated carbon filter is recommended.
Where does Port Wentworth's water come from?
Port Wentworth's water is sourced from Groundwater. The city has 5 water systems serving approximately 50,806 residents.
What health violations has Port Wentworth's water system had?
Port Wentworth has 6 health-based violations on record. The most recent violation was recorded in August 2025. Health-based violations mean the water exceeded EPA maximum contaminant levels (MCLs) for a regulated substance. 41 violations remain unresolved.
Is Port Wentworth's groundwater at risk of contamination?
Port Wentworth uses groundwater, which can be affected by naturally occurring contaminants like arsenic, radon, and nitrate, as well as agricultural runoff and industrial activity. The system has 75 violations on record that may relate to groundwater quality. Groundwater systems are generally less susceptible to surface contamination but should be monitored for emerging contaminants like PFAS.
Why does Port Wentworth have so many PFAS compounds in its water?
4 different PFAS "forever chemical" compounds were detected in Port Wentworth's water supply during UCMR 5 testing. PFAS contamination often originates from proximity to military installations (AFFF firefighting foam), airports, industrial manufacturing sites, or wastewater treatment facilities. Some levels exceed the 2024 EPA maximum contaminant levels — a reverse osmosis or NSF-certified activated carbon filter is strongly recommended.
How does Port Wentworth's water compare to other cities?
Port Wentworth ranks #310 out of 378 cities in Georgia (better than 18% of state cities) and #12588 out of 15744 cities nationally (20th percentile). The grade of D+ reflects the combined assessment of violation history, lead and copper levels, PFAS contamination, and regulatory compliance.
