Water source & infrastructure
Where Spring's water comes from
Spring's drinking water is drawn from underground aquifers through wells.
Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals.
Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds.
The system is operated by local government ownership and serves approximately 28,488 people through 37 water systems.
Water bodies near Spring
Spring is located near 5 notable water bodies. These water bodies contribute to the regional watershed and may indirectly affect groundwater quality.

Frequently asked questions
Is Spring, TX tap water safe to drink?
Spring's water quality earned a grade of F (42.2/100). Significant issues have been found. A water filter is strongly recommended. The city ranks #958 out of 1067 cities tested in Texas.
What contaminants are in Spring's water?
Lead was measured at 0.0 ppb (90th percentile). 3 PFAS compounds were detected. 619 violations are on record.
How is Spring's water quality grade calculated?
The grade is based on four factors: violation history (40%), lead and copper levels (25%), PFAS contamination (25%), and regulatory compliance (10%). The score is also adjusted based on how complete the available data is. See our methodology page for full details.
Do I need a water filter in Spring?
PFAS compounds have been detected. A filter with activated carbon can help reduce exposure.
Where does Spring's water come from?
Spring's water is sourced from Groundwater. The city has 37 water systems serving approximately 28,488 residents.
What health violations has Spring's water system had?
Spring has 36 health-based violations on record. The most recent violation was recorded in November 2025. Health-based violations mean the water exceeded EPA maximum contaminant levels (MCLs) for a regulated substance. 211 violations remain unresolved.
Is Spring's groundwater at risk of contamination?
Spring 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 619 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 Spring have so many PFAS compounds in its water?
3 different PFAS "forever chemical" compounds were detected in Spring'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. While detected, current levels are within EPA limits. An activated carbon filter can further reduce exposure.
How does Spring's water compare to other cities?
Spring ranks #958 out of 1067 cities in Texas (better than 10% of state cities) and #14834 out of 15744 cities nationally (6th percentile). The grade of F reflects the combined assessment of violation history, lead and copper levels, PFAS contamination, and regulatory compliance.
