Phase-I & Phase-Ii Environmental Site Assessments

Phase-I & Phase-Ii Environmental Site Assessments

YAPI GROUP Environmental regularly performs Phase-I and Phase-II environmental site assessments for our clientele. This due diligence affords them liability protection under the American Society for Testing and Materials with ASTM E1527-13 designation. We use in-depth site investigation, personal interviews, and historical research to uncover potential contamination or other environmental conditions on a subject site.

We use the ASTM E1527-13 standard to prepare our reports, and we are more than happy to tailor our research to focus on the client's specific concerns. We do mostly serve the following industries:

  • Financial Institutions & Banks
  • Commercial Real Estate Investors
  • Commercial Real Estate Agents
  • Federal & State Government Agencies
  • Commercial Property Development Investors

We are used to working under tight deadlines. Even if you have waited until the last minute to schedule Phase I and Phase II environmental site assessments, call us.



YAPI GROUP's Environmental Consultants team reviews the site records and performs a site visit for the inspection. We conduct interviews with owners, occupants, neighbors, and local government officials. Our Phase-I assessment also includes sampling and laboratory analysis by environmental professionals trained in the appropriate standards. Depending on the results of the samples, the Phase-II ESA should outline additional site investigation needs and potential remedial actions that may be required to clean up the property.

YAPI GROUP performs a complete comprehensive Environmental Site Assessment (ESA) in accordance with the (1) United States Environmental Protection Agency (USEPA) Standards and Practices for All Appropriate Inquiries {(AAI), 40 CFR Part 312} and (2) guidelines established by the American Society for Testing and Materials (ASTM) in the Standard Practice for Environmental Site Assessments: Phase-I Environmental Site Assessment Process / Designation E1527-13 (ASTM Standard Practice E1527-13): Phase-I Environmental Site Assessment may be used for real estate transactions, property development, bank financing, re-financing, foreclosures, and other in-house proactive audit programs.

The purpose of a Phase-I Environmental Site Assessment is to gather sufficient information to develop an independent professional opinion about the environmental condition of the property and to identify actual or potential environmental contamination which may impact the property value or affect the claim to an "innocent landowner" exemption following the acquisition.

Our Phase-I ESA Services include the following;

  • Completed ASTM E1527-2013 Standard, satisfying All Appropriate Inquiry (AIA).
  • Executive Summary, Clear Scope of Work, and Provision of Supporting Documentation and Sources Checked are included in the Phase-I ESA.
  • In-house Research Department with an extensive archive of historical information.
  • On-Site Reconnaissance for a Standard Phase-I ESA with in-depth interviews of knowledgeable site contacts.
  • Interviews with appropriate Government and Private Sector Sources of Information.
  • Review of Standard Environmental Record Sources from Local, State, and Federal Agencies within ASTM Approximate Minimum Search Distances.
  • Regular updates for all Stakeholders during the process.
  • Strict Client confidentiality.
  • Clear summary of Recognized Environmental Conditions (RECs).
  • Incorporation of specific Lender requirements for Issuance or Reliance Language for the purposes of making loan decisions.
  • If conditions warrant additional investigation, a written Phase-II Environmental Site Assessment Proposal describing means for identifying and characterizing environmental contamination revealed during a Phase-I ESA can be prepared upon request.
  • HUD, Fannie Mae/Freddie Mac compliant.
  • Use of PARCEL for multiple site portfolios.
  • Visual Inspections.

Should a Phase-I ESA report identify potential contamination of the site by hazardous materials, a Phase-II ESA would be a must. The Phase-II ESA usually includes sampling and laboratory analysis to confirm the presence of hazardous materials.

Some of the tests may be performed:

  • Drum sampling (if applicable for a subject property).
  • Surficial soil, monitoring wells, and other water sampling.
  • Sampling of dry wells, floor drains, and catch basins.
  • Testing of (USTs) Underground Storage Tanks.
  • Subsurface soil borings.
  • Groundwater monitoring well installation, sampling, and analysis. It also may be appropriate on neighboring properties as well to determine the presence of contamination levels.
  • Transformer/capacitor sampling for Polychlorinated Biphenyls (PCBs).
  • Geophysical testing for buried tanks and drums.
  • Asbestos, Lead, Radon, Mold, and other regulated material & component assessments and remediation.

  • Visual inspection: A complete visual inspection of the property, including the building envelope and surrounding landscape.
  • Determination of moisture intrusion and/or relative humidity sources.
  • Fungal sampling: air, surface, or bulk sampling techniques to determine the type and level of contamination.
  • A written report detailing our findings and recommendations to remediate the problem areas and prevent future occurrences of mold growth.

We offer limited assessments and testing to meet the needs of our clients when full assessments and/or investigations may not be a viable option.

YAPI GROUP project managers can provide an effective plan for the remediation or decontamination of any size or type of building. Abating affected building materials, in conjunction with the corrective actions associated with moisture intrusion, is the goal of any mold abatement activity. The extent of removal, the engineering controls to be used, worker protection, and the clean-up procedures are strategies that must be developed, typically on a site-specific basis.

We offer environmental oversight during mold remediation projects, including pre-and post-remediation bio-aerosol sampling. During the remediation process, trained specialists can monitor the project to help ensure safety and industrial hygiene and that the project stays within budget and on schedule. Titan can also assist in selecting an experienced, qualified mold remediation contractor.

Mold encountered in flood or water-damaged environments grows best at room temperature.


It is a myth that mold will grow only in dark environments. Usually, mold grows better in the dark because there is more moisture available. However, many molds will begin disseminating their spores when they are exposed to light.


Cellulose is a preferred nutrient for mold growth. Examples include carpet, wood, trim, dust/dirt, and drywall. Not only does mold use building materials for nutrients, but it also compromises its structural integrity.


Water is the most crucial factor in mold growth. Every species of mold requires a different amount of available moisture in order to grow.


EPA Radon Studies

The EPA offers a look at what they believe to be the risks of radon at different concentrations for 1,000 people who smoked and were consistently exposed to a certain level of radon during their lifetimes.

EPA Radon Studies

The EPA offers a look at what they believe to be the risks of radon at different concentrations for 1,000 people who smoked and were consistently exposed to a certain level of radon during their lifetimes.

Radon Risks for Smokers

  • With exposure to 10 pCi/L, about 71 would get cancer, equal to 100 times the risk of dying in a home fire.
  • With exposure to 4 pCi/L, about 29 would get cancer, equal to 100 times the risk of dying in a plane crash.

Radon Risks for Nonsmokers

  • With exposure to 8 pCi/L, about 3 would get cancer, equal to 10 times the risk of dying in a plane crash.
  • With exposure to 4 pCi/L, about 2 would get cancer, equal to the risk of drowning.

Acceptable Radon Levels

The Environmental Protection Agency, EPA, recommends you install a system to reduce radon gas in your home if the level of gas is 4 picocuries of radon per liter (pCi/L) or higher.

Facts about Radon Gas

  • There are no average radon levels for a specific city, state, or region.
  • Houses without basements are as much at risk of radon contamination as houses with basements.
  • It doesn't matter if your neighbor's radon test was low or high, results for your home may be completely different.

We take a comprehensive approach to performing mold investigations, as many different factors must be considered when trying to identify the source of contamination. A thorough building and occupant history, followed by a detailed visual inspection to identify sources and conditions, form the basis of the investigation. Clear objectives and criteria are established before any sampling or analysis is undertaken to ensure that useful and sensible data is generated in the complex arena of mold contamination. A wide variety of field tools are used to help sample and identify the types of mold and the extent of mold contamination.
