Wisconsin Regulatory Compliance, Backed by Metiri Expertise
Environmental compliance in Wisconsin is governed by the Wisconsin Department of Natural Resources (DNR) and the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP).
Metiri supports clients across the regulatory programs most relevant in the state, including:
- Air monitoring and compliance
- Drinking water and residential testing
- Groundwater investigations
- Brownfield soil testing
- Tank removal soil testing
- Surface water and stormwater programs
- Wastewater and pretreatment monitoring
Our teams work closely with clients to ensure sampling, analysis, and reporting align with Wisconsin’s specific accreditation and approval requirements.
Services Across Key Programs in Wisconsin
Wisconsin organizations most commonly rely on Metiri for air testing, municipal and residential drinking water testing, groundwater and soil analysis, surface water and stormwater monitoring, and wastewater and industrial pretreatment sampling.
Across these services, Metiri supports clients through routine compliance monitoring, permit-driven sampling and analysis, troubleshooting and investigations, and data interpretation to support regulator interactions.
By combining technical expertise with responsive coordination, we help clients navigate tight turnaround timelines, changing permits, and day-to-day operational decisions using clear, usable results.
PFAS Testing & Support in Wisconsin
PFAS monitoring and regulation are actively expanding across Wisconsin. PFAS are increasingly being added to wastewater and solids permits as they are renewed, and accredited testing must be performed by laboratories approved by the Wisconsin DNR, as the state does not recognize reciprocity.
Metiri supports PFAS analysis across relevant matrices, including:
- Drinking water
- Groundwater
- Soil
- Surface water
- Wastewater
- Biosolids
PFAS Methods 533 and 537 are coming online soon, expanding accredited capabilities for Wisconsin-regulated programs.
With state-recognized accreditations, validated methods, and experienced technical teams, Metiri helps clients stay ahead of PFAS requirements as enforcement and monitoring continue to expand.
Certifications & Data Credibility
Metiri’s Wisconsin clients are supported by laboratories holding the only accreditations accepted by the state, including:
- Mequon, WI: Certified by the Wisconsin DNR and DATCP
- Geneva, IL: Certified by the Wisconsin DNR and DATCP
These accreditations are critical for drinking water, wastewater, PFAS, and air programs and ensure all data produced is suitable for regulatory submission and compliance decision-making in Wisconsin.
