Understanding Monroe County’s Water

Drinking Water Quality Overview

EPA SDWIS

Monroe County's water systems carry a failing grade, scoring 15.5 out of 100. Over the past five years, EPA SDWIS records 176 health-based violations — a pattern that public water utilities are required to disclose and correct.

Watershed Conditions

EPA ATTAINS

Under the Clean Water Act §303(d), EPA ATTAINS tracks whether waterways meet quality standards for drinking, recreation, and aquatic life (reporting cycle: 2022). None of the assessed waterways are listed as impaired (0 of 29,942 water bodies) across Monroe County's watersheds. Impairment does not mean tap water is unsafe — it measures ambient waterway conditions upstream of treatment, not finished drinking water.

River & Streamflow Status

USGS NWIS

USGS NWIS gauge data (as of 2026-05-14T14:00:00.000-04:00) puts Brodhead Creek at 416.0 cfs — running somewhat below its historical average at 72% of mean. 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. Monroe County has moderate coverage with 36 active monitoring sites with 17,041 recent measurements on record. Predominant monitoring categories include physical and inorganics, minor, 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 Monroe County

Water Verdict

Monroe County receives a poor water quality assessment with a grade of F and a score of 15.5 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

Monroe County has recorded 176 health-based violations, indicating multiple instances where federal contaminant limits or treatment requirements were not met. At 188.8 violations per 100,000 people served, this rate is high and signals significant water quality management issues.

Consumer Guidance

Monroe County has a Grade F compliance record with 176 health-based violations — among the highest levels in the country. Monroe County's drinking-water compliance score is 15.5 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 Pennsylvania Department of Environmental Quality or Health can expedite utility compliance action. With 36 active water-quality monitoring sites in Monroe County, data coverage is strong. A pipeline streamflow snapshot from the Brodhead Creek gauge is also available on this page.

Regional Context

Monroe County has poorer water quality than the average county in Pennsylvania. Its water score is 23.4 points lower than the state average, suggesting more challenges with contamination control or infrastructure than neighboring counties.

Top Impairment Causes

No specific impairment causes reported for the assessed water bodies in this county.

Source: EPA ATTAINS · Reporting cycle 2022

Impairment is determined under the Clean Water Act §303(d): a water body is impaired when it fails to meet state-defined quality standards for designated uses (drinking, recreation, aquatic life). Assessment coverage varies by state; counties without assessed water bodies are not shown.

Frequently Asked Questions

What is the water quality in Monroe County, Pennsylvania?
Monroe County, Pennsylvania has a drinking-water quality grade of F with a score of 15.5/100, based on EPA SDWIS compliance data. The county has 176 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 Monroe County?
Monroe County has 176 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 healthy are the watersheds in Monroe County?
EPA ATTAINS assessments under Clean Water Act §303(d) indicate 0.0% of Monroe County's 29,942 assessed water bodies are classified as impaired (0 impaired). Impairment means the water body fails to meet state quality standards for at least one designated use — drinking water source, recreation, aquatic life, or fish consumption. Note: watershed impairment doesn't always translate to tap-water issues; treatment plants can remove most regulated contaminants.
How much water-quality monitoring happens in Monroe County?
EPA's Water Quality Portal records 17,041 measurements from 36 monitoring sites in Monroe County over the past five years. The most frequently measured characteristic groups are Physical, Inorganics, Minor, Metals, Nutrient. 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 Monroe County right now?
Monroe County's primary USGS streamgage on the Brodhead Creek has a pipeline snapshot of 416 cubic feet per second — 72% of the long-term mean of 580.11 cfs. Flow is within typical range for this gauge. For the latest gauge feed, visit waterdata.usgs.gov.
How does Monroe County water compare to the Pennsylvania average?
Monroe County's SDWIS water quality score of 15.5/100 is lower than the Pennsylvania state average of 38.9. The average water quality grade across Pennsylvania is F, based on data from 67 counties with available SDWIS data.
Is tap water safe to drink in Monroe County?
Based on EPA SDWIS data, Monroe County has a water quality grade of F (15.5/100). 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 Monroe County have so many water violations?
Monroe County has 176 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 Monroe County rank for water quality in Pennsylvania?
Monroe County ranks #57 out of 67 counties in Pennsylvania by SDWIS water quality score (1 = best). With a score of 15.5/100, it falls in the bottom third of counties statewide.
