Understanding Jasper County’s Water

Drinking Water Quality Overview

EPA SDWIS

Jasper County's water systems carry a failing grade, scoring 9.2 out of 100. Over the past five years, EPA SDWIS records 113 health-based violations — a pattern that public water utilities are required to disclose and correct.

River & Streamflow Status

USGS NWIS

USGS NWIS gauge data (as of 2026-05-14T13:00:00.000-05:00) puts Neches Rv at 3.5k cfs — well below its long-term average at 57% of mean — low-flow conditions worth noting for water-dependent ecosystems. Streamflow is a leading indicator of drought stress, sediment load, and dilution capacity: low flows concentrate pollutants and warm water temperatures, stressing aquatic life and, in surface-water-dependent systems, the source water quality for treatment plants.

Monitoring Network

EPA WQP

EPA's Water Quality Portal (WQP) aggregates monitoring data from federal, state, and tribal agencies. Jasper County has moderate coverage with 12 active monitoring sites with 3,538 recent measurements on record. Predominant monitoring categories include physical and inorganics, major, non-metals. More monitoring sites generally indicate greater scientific attention to local water conditions — and provide the baseline data that regulators use to set future impairment listings.

Editorial advisory

What the data suggests for Jasper County

Water Verdict

Jasper County receives a poor water quality assessment with a grade of F and a score of 9.2 out of 100. The water supply has documented quality issues. Residents are strongly encouraged to use filtered or bottled water for drinking and to stay informed about utility improvement plans.

Violation Context

Jasper County has recorded 113 health-based violations, indicating multiple instances where federal contaminant limits or treatment requirements were not met. At 366.6 violations per 100,000 people served, this rate is high and signals significant water quality management issues.

Consumer Guidance

Jasper County has a Grade F compliance record with 113 health-based violations — among the highest levels in the country. Jasper County's drinking-water compliance score is 9.2 out of 100. Residents are strongly advised to use a certified NSF 58 reverse-osmosis filter or bottled water for all drinking and cooking until violations are corrected. Contacting the Texas Department of Environmental Quality or Health can expedite utility compliance action. With 12 active water-quality monitoring sites in Jasper County, data coverage is strong. A pipeline streamflow snapshot from the Neches Rv gauge is also available on this page.

Regional Context

Jasper County has poorer water quality than the average county in Texas. Its water score is 21.2 points lower than the state average, suggesting more challenges with contamination control or infrastructure than neighboring counties.

Frequently Asked Questions

What is the water quality in Jasper County, Texas?
Jasper County, Texas has a drinking-water quality grade of F with a score of 9.2/100, based on EPA SDWIS compliance data. The county has 113 health-based drinking water violations over the past 5 years. Watershed health, monitoring records, and streamflow snapshots are reported separately on this page.
Are there any water violations in Jasper County?
Jasper County has 113 health-based drinking water violations recorded by the EPA over the past 5 years. Health-based violations indicate instances where contaminant levels exceeded EPA Maximum Contaminant Levels (MCLs). Violations may have been resolved — check with your local water utility for current status.
How much water-quality monitoring happens in Jasper County?
EPA's Water Quality Portal records 3,538 measurements from 12 monitoring sites in Jasper County over the past five years. The most frequently measured characteristic groups are Physical, Inorganics, Major, Non-metals, Inorganics, Minor, Metals. Each measurement is a single sample analyzed for one characteristic (E. coli, pH, dissolved oxygen, etc.). High monitoring density means more scientific evidence behind any reported signal — it does not by itself indicate water quality.
What's happening with rivers in Jasper County right now?
Jasper County's primary USGS streamgage on the Neches Rv has a pipeline snapshot of 3,450 cubic feet per second — 57% of the long-term mean of 6,008.69 cfs. This is well below typical — often a signal of drought stress on source water. For the latest gauge feed, visit waterdata.usgs.gov.
How does Jasper County water compare to the Texas average?
Jasper County's SDWIS water quality score of 9.2/100 is lower than the Texas state average of 30.4. The average water quality grade across Texas is F, based on data from 254 counties with available SDWIS data.
Is tap water safe to drink in Jasper County?
Based on EPA SDWIS data, Jasper County has a water quality grade of F (9.2/100). This indicates below-average compliance with significant violations. Residents may want to consider home water filtration or independent testing. The grade speaks to the public water system, not the watershed — for watershed-level concerns, see the Watershed Health zone. For the most up-to-date information, contact your local water utility or review your Consumer Confidence Report (CCR).
Why does Jasper County have so many water violations?
Jasper County has 113 health-based drinking water violations on record from the EPA SDWIS database. A higher violation count can result from aging infrastructure, underfunded water utilities, agricultural runoff contamination, or industrial pollution. Counties with more water systems may also see more violations simply due to scale. Residents concerned about water quality should consider independent water testing and home filtration systems.
How does Jasper County rank for water quality in Texas?
Jasper County ranks #188 out of 254 counties in Texas by SDWIS water quality score (1 = best). With a score of 9.2/100, it falls in the bottom third of counties statewide. The ranking reflects EPA SDWIS compliance only — not watershed impairment, monitoring density, or streamflow, which are tracked separately on this page.
