PHASE I ENVIRONMENTAL SITE ASSESSMENTS

Laakea will perform environmental site assessments (ESAs) applying comprehensive records review, site reconnaissance, and interviews pursuant to the industry standards and the published ASTM E1527-13.  The ESA will identify the presence of recognized environmental conditions during property transactions, sales, or ownership modifications.

Laakea will review readily available records to help identify likely contaminants and locations, such as facility Information, including building plans, state and federal permitting records, prior audits/assessments, and compliance records.  Potential contaminant migration pathways, such as topographic information, existing soil and subsurface data, groundwater information, environmental and health record databases and public records will be thoroughly evaluated.

During the required site visit, Laakea will observe and evaluate features such as odors, groundwater wells, vents, pits, ponds, lagoons, drums or storage containers, stained soil or pavement, distressed vegetation, waste storage areas, or tank piping. We will conduct interviews of relevant site individuals to obtain additional information on prior and/or current uses and conditions of the property. Such individuals will include current and past site owner and/or site manager, site occupants, government officials, neighbors, and the user. Indications of recognized environmental conditions identified during this comprehensive ESA may warrant a Phase II Environmental Site Assessment.

PHASE II ENVIRONMENTAL SITE ASSESSMENTS

A Phase II ESA may be required to determine whether the identified historic on-site or off-site recognized environmental conditions have impacted the soil and/or groundwater conditions associated with a property.  Depending on these environmental conditions, a subsurface evaluation of soil and groundwater may be necessary.

During the Phase II ESA, a determination is made whether the integrity of the property has been impacted by past or historic uses. This appraisal is made through the sampling and chemical analysis of appropriately sampled media – construction material, soil, or groundwater. The site data are compared to the appropriate set of screening levels for contaminants in soil and/or groundwater using an appropriate risk-based method.

Based on the results, it may be appropriate to declare that the recognized environmental condition identified during the Phase I ESA has not created a situation that is detrimental to human health or the environment.  However, the results may also dictate further investigation or the site status may require appropriate remediation of the impacted media.
