Managing Environmental Risk or Compliance
Addressing Indoor Environmental Concerns
Or if you know exactly what you need:
-
Phase I Environmental Site Assessments (ASTM E1527-21 compliant) are conducted to identify recognized environmental conditions and potential liability associated with a property. These reports are typically required during commercial real estate transactions, financing, and redevelopment.
-
Phase II Environmental Site Assessments involve soil, groundwater, or vapor sampling to confirm the presence and extent of contamination identified during a Phase I ESA. These investigations help guide risk evaluation, remediation planning, and regulatory decisions.
-
Regulatory compliance services include permitting support, reporting, site compliance strategy, and coordination with environmental agencies to ensure projects meet applicable requirements.
-
Environmental remediation services address contaminated soil, groundwater, and environmental impacts through investigation, cleanup planning, and implementation in accordance with regulatory requirements.
-
Indoor air quality assessments evaluate building conditions that may impact occupant health and comfort, including ventilation performance, airborne contaminants, moisture-related issues, and odor concerns. These assessments are commonly performed in commercial, multifamily, and workplace environments where air quality concerns arise.
-
Aquifer and groundwater analysis supports development planning, hydrogeologic evaluation, and regulatory review for projects involving subsurface conditions.
-
Asbestos and mold services include inspection, sampling, and assessment to identify hazardous building materials and moisture-related conditions. These services support renovation, demolition, property management, and regulatory compliance, ensuring risks are properly identified and addressed before work proceeds.
-
Brownfield redevelopment services support the assessment, cleanup, and repositioning of environmentally impacted properties for reuse and development. These projects often involve historical contamination, regulatory coordination, and liability considerations that must be addressed before construction or financing can move forward.
-
CRB provides expert witness services including technical analysis, reporting, and testimony for environmental litigation, negotiations, and regulatory proceedings.
Why Clients Choose CRB Over Other Environmental Consultants
Not all environmental consultants approach projects the same way.
CRB is built around the realities of real estate transactions, not just environmental reporting. We understand that environmental is a critical step in keeping deals moving, protecting against liability, and meeting lender and regulatory requirements without unnecessary delays.
Our team has extensive experience working on high-risk and complex sites, including gas stations, dry cleaners, industrial facilities, and properties with historical contamination. These are the types of projects where environmental oversight matters most, and where experience directly impacts timelines and outcomes.
We take a practical approach to environmental consulting. Our focus is on clearly identifying risk, providing defensible conclusions, and aligning recommendations with the needs of the project. We do not overcomplicate the process or introduce unnecessary scope that can delay progress.
CRB also works closely with lenders, attorneys, developers, and property owners, with a clear understanding of how environmental findings affect financing, closing timelines, and liability. Our reports and communication are structured to support decision-making, not slow it down.

Commonly Asked Questions
What is a Phase I Environmental Site Assessment?
1
A Phase I Environmental Site Assessment is a due diligence report conducted to evaluate potential environmental risks associated with a property. It involves a review of historical records, regulatory databases, site conditions, and surrounding land use to identify recognized environmental conditions (RECs). Phase I ESAs are commonly required by lenders and are performed in accordance with ASTM E1527-21 standards to support liability protection under the EPA’s All Appropriate Inquiry (AAI) rule.
When is a Phase II ESA required?
2
A Phase II Environmental Site Assessment is recommended when a Phase I ESA identifies a recognized environmental condition that warrants further investigation. This typically involves soil, groundwater, or vapor sampling to confirm whether contamination is present, determine its extent, and evaluate potential risk to human health or the environment. Phase II scopes are developed based on the specific findings of the Phase I.
How long do environmental reports take?
3
Phase I Environmental Site Assessments typically take 2 to 4 weeks to complete, depending on property complexity, records availability, and site access. Expedited timelines may be available for time-sensitive transactions. Phase II ESA timelines vary based on the scope of work, including sampling requirements, laboratory analysis, and site conditions, but generally range from a few weeks to several months.
Who typically needs a Phase I Environmental Site Assessment?
4
Phase I ESAs are typically required by lenders, real estate investors, developers, and property owners involved in commercial real estate transactions, refinancing, or redevelopment projects. They are used to assess environmental risk prior to acquisition and to qualify for liability protections under federal regulations. Even when not required, many buyers choose to complete a Phase I ESA to avoid unexpected environmental liabilities and delays during closing.
