In Plain English, Not Jargon.
Underground and above-ground storage tanks (USTs & ASTs) can pose major environmental liabilities if not assessed and managed properly. Our Tank System Site Assessments identify leaks, system integrity issues, and regulatory risks—giving you clear next steps, full documentation, and peace of mind. Whether you’re buying a property, upgrading tanks, or meeting agency requirements, we deliver fast, compliant, and cost-effective results.
We start by identifying and mapping all tanks on-site, both active and abandoned. This includes confirming location, capacity, contents, construction materials, and age. Accurate mapping prevents future surprises and ensures a full understanding of potential contamination sources.
Our team uses pressure testing, visual inspection, and monitoring data to check for leaks or system failures. We assess piping, secondary containment, overfill protection, and more—ensuring tanks meet federal and state safety standards.
We collect and analyze soil and groundwater samples near tanks to detect possible petroleum or chemical releases. If contamination is found, we provide recommendations for further investigation or cleanup, tailored to your budget and timeline.
We prepare all required documentation for DNR, EPA, and local agency compliance. This includes assessment reports, sampling logs, site maps, and next-step guidance. Our clients avoid fines and delays by staying ahead of regulatory expectations.
If a tank system is scheduled for removal or replacement, we guide you through proper closure assessment and reporting. We also assist with permitting, contractor coordination, and future land-use planning to ensure your project stays on track.

ESA Frequently Asked Questions
Find answers to common questions about our environmental assessment services and processes.
An Environmental Site Assessment (ESA) is a process to evaluate potential environmental contamination on a property. Phase I ESAs identify potential risks based on historical usage and current conditions. Phase II ESAs involve more detailed testing to confirm any contamination.
Costs vary based on property size, scope, and whether it’s a Phase I or Phase II ESA. However, we’re more affordable than large firms—no bloated overhead or surprise fees. Contact us for a clear, upfront quote.
We specialize in Phase I and Phase II ESAs, soil and water sampling, and remediation services. Our team also provides regulatory compliance reporting tailored to Wisconsin's requirements. Each service is designed to protect your investment and ensure compliance.
Anyone involved in property transactions, including buyers, sellers, and lenders, should consider an ESA. It's crucial for identifying potential environmental liabilities. Attorneys and real estate developers also benefit from our assessments to ensure compliance and protect investments.
If contamination is detected, we’ll walk you through next steps and outline cost-effective remediation options. We never leave you in the dark—we become your partner in solving the problem quickly and correctly.
We move faster, charge less, and give you direct access to your consultant—no runarounds, no inflated staff costs. Our clients appreciate our transparency, flexibility, and clear communication from start to finish.
A Phase I ESA involves reviewing historical records, site inspection, and interviews to identify any signs of environmental concerns. A Phase II ESA includes actual sampling of soil, groundwater, or vapor to confirm or rule out contamination.
No. If the Phase I shows no signs of environmental concern, a Phase II is typically unnecessary. We’ll never recommend more testing than your site needs.
We work with commercial, industrial, agricultural, and mixed-use sites—from gas stations and warehouses to redevelopment properties and vacant land.
Phase I assessments typically take 5–10 business days. Phase II timelines depend on the scope of testing but are often completed within 2–3 weeks. We prioritize quick turnarounds without sacrificing thoroughness.
