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.
