Summary

HARRISON UTILITIES - FKA WAVERLY SD serves approximately 5,500 people in MENASHA, Wisconsin. Based on contaminant analyses from DNR, WQP, EPA ECHO, EPA UCMR5, 0 contaminants have been measured above federal EPA standards (MCL) and 0 exceed health-based guidelines. No contaminants were measured above federal EPA standards in recent compliance monitoring. Data is drawn from source-level compliance monitoring and covers 1995 through 2026. Results reflect conditions at the point of collection (wells, treatment plants), not necessarily at the tap.

Key Findings

Understanding the two thresholds

EPA Legal Limit (MCL)

The highest level of a contaminant allowed by federal law. Utilities that exceed this threshold face enforcement action. Limits balance health risk against the cost of treatment, so they are not always set at levels considered safe by independent researchers.

Health Guideline

The level below which independent researchers (CalEPA, WHO, EWG) believe there is no known health risk. Guidelines are not legally enforceable but are typically stricter than legal limits — often by 10x or more for contaminants like arsenic and lead.

A reading can be below the EPA limit (legally compliant) while still exceeding health guidelines (above levels considered safe by independent researchers).

PFAS

Per- and polyfluoroalkyl substances (PFAS) are a group of manufactured chemicals that persist in the environment and accumulate in the human body. The EPA set enforceable limits for six PFAS compounds in April 2024, with a compliance deadline of 2029. PFAS compounds measured above EPA standards appear in the Above Federal Standard section above.

Microplastics

Microplastics have been documented in raw and treated drinking water worldwide, but federal regulations do not currently require testing — so there is no data specific to this system. Standardized methods and rules are in progress.

Other Regulated Contaminants

These contaminants were detected within federal standards (EPA Maximum Contaminant Levels). They are presented for transparency.

Total Trihalomethanes (TTHMs) (LRAA): 34.53 ug/Lwithin limit of 80 ug/L

EPA Stage 2 DBPR — Locational Running Annual Average, system-wide, based on 8 samples across 4 quarters (2025Q2 · 2025Q3 · 2025Q4 · 2026Q1).

Disinfection byproducts are regulated as a running average under Stage 2 DBPR, not as individual samples. A single sample exceeding the MCL is not itself a compliance violation — the annual running average is the enforceable metric.

Haloacetic Acids (HAA5) (LRAA): 19.41 ug/Lwithin limit of 60 ug/L

EPA Stage 2 DBPR — Locational Running Annual Average, system-wide, based on 8 samples across 4 quarters (2025Q2 · 2025Q3 · 2025Q4 · 2026Q1).

Disinfection byproducts are regulated as a running average under Stage 2 DBPR, not as individual samples. A single sample exceeding the MCL is not itself a compliance violation — the annual running average is the enforceable metric.

Unregulated Detected Contaminants

These contaminants were detected but do not have a federal Maximum Contaminant Level. They are monitored for awareness, not compliance.

Other Potential Contaminants

Not detecting a contaminant does not prove it isn't present — it only means the laboratory didn't test for it, or tested below the reporting limit. Many substances of emerging concern are not routinely monitored because federal regulations haven't caught up to the science.

Compliance History

Formal EPA and DNR compliance events on record for this utility. Includes all events from the last 10 years plus any unresolved violations regardless of age. Health-based violations are legally enforceable thresholds that were exceeded; procedural events are monitoring or reporting lapses that don't indicate contamination by themselves.

No EPA compliance events on record for this utility.

Routine Maintenance

Nothing in this system's current readings crosses a legal limit or a health guideline. Water systems still change over time, so the following is a baseline of habits worth keeping.

Frequently Asked Questions

What contaminants are in MENASHA water?

Based on available public monitoring data, 35 contaminants have been tested in MENASHA's water supply. 6 were detected above reporting limits. The most notable detections include Chlorine (total residual), Haloacetic Acids (HAA5), Total Trihalomethanes (TTHMs). This data comes from source-level compliance monitoring at wells and treatment plants.

Does MENASHA water meet EPA standards?

Based on available public monitoring data, no contaminants were measured above federal EPA standards in recent compliance monitoring. This assessment is based on source-level monitoring data (wells and treatment plants), not tap-level measurements.

Is MENASHA WI water safe to drink?

Based on source-level compliance monitoring, all tested contaminants were within federal standards. However, compliance monitoring tests water at wells and treatment plants, not at individual taps. An on-site test is the only way to know what reaches your tap, as conditions can vary based on plumbing, blending, and distribution.

Does MENASHA water have PFAS?

Yes, PFAS compounds have been detected in source monitoring for MENASHA's water supply: PFBA (Perfluorobutanoic Acid) (0.005 ug/L). PFAS are a group of manufactured chemicals that do not break down in the environment. The EPA set enforceable limits for several PFAS compounds in 2024.

Does MENASHA water have lead?

No. MENASHA's most recent Lead and Copper Rule testing found a 90th-percentile lead level of 0 mg/L, which is below the EPA action level of 0.015 mg/L. That means at the systemwide level, lead is not exceeding the enforcement threshold. Lead levels can still vary significantly by individual building — older homes and schools with legacy plumbing can have much higher readings than the system average.

Cross-check against the official record

This report is our read of the public monitoring data. Every Wisconsin utility also publishes an annual Consumer Confidence Report (CCR) — a plain-language summary written by the utility itself, usually mailed with a water bill or posted on the utility's website. If anything in this report surprises you, request HARRISON UTILITIES - FKA WAVERLY SD's latest CCR directly from the utility, or browse the underlying compliance data on the Wisconsin DNR portal.

EPA UCMR5

Unregulated Contaminant Monitoring Rule, Fifth cycle. Per-analyte PFAS results from utility-level sampling.

Definitions

Maximum Contaminant Level (MCL)
The highest level of a contaminant allowed in drinking water, set by the EPA. MCLs are legally enforceable standards.
Maximum Contaminant Level Goal (MCLG)
The level of a contaminant below which there is no known or expected health risk. MCLGs are non-enforceable public health goals.
Action Level
The concentration of a contaminant which, if exceeded, triggers treatment or other requirements. Used for lead and copper.
Health Advisory
Non-enforceable guidelines set by the EPA providing information on contaminants that can cause health effects at certain exposure levels.
Total Dissolved Solids (TDS)
A measure of all dissolved minerals, salts, and organic matter in water, expressed in mg/L (ppm). Not a health hazard but affects taste and indicates overall mineral content.
PFAS
Per- and polyfluoroalkyl substances. A group of manufactured chemicals that do not break down in the environment. The EPA set enforceable limits for several PFAS compounds in 2024.
Non-Detect (ND)
The contaminant was tested for but not found above the laboratory's reporting limit. This does not mean zero — it means below the detection threshold.
VOCs (Volatile Organic Compounds)
Chemicals that evaporate easily and can contaminate groundwater. Sources include gasoline, industrial solvents, and dry cleaning fluids. Some are regulated by the EPA; many are monitored but not yet regulated.
