What is a Phase I and II environmental site assessment?
A Phase I primarily assesses the likelihood that a site is contaminated through visual observations, historical use reviews and regulatory records, while a Phase II assesses whether contamination is in fact present.
What is a Phase 3 environmental?
Phase III Environmental Site Assessments Phase III ESA’s, also known as Remediation Investigations/Feasibility Studies, are a necessary step in the environmental remediation process of environmental contaminants from a property. Determining the amount of soil and groundwater impacted by environmental contaminants.
What are the four phases of environmental contamination?
Organic contaminants may exist in the subsurface in four distinct phases: mobile free product, absorbed phase, dissolved phase and vapor phase. The free product is known as non-aqueous phase liquid (NAPL) and can be denser than water, DNAPL, or lighter than water, LNAPL.
What is a limited phase II?
A limited Phase II is sampling necessary just to confirm the presence of a pollutant. A comprehensive Phase II ESA includes extensive sampling to fully characterize the extent of contamination and analysis of potential migration pathways and potential receptors so that cleanup costs can be estimated.
How many types of environmental impacts are there?
Types of Environmental Impacts: Direct , Indirect , Cumulative and Induced Impact.
What does a Phase 1 environmental cost?
Phase I environmental site assessment costs usually start at around $1400 but can go up to $4600 or above, depending on the size and complexity of the site assessment. Some firms are open to discounting the price if you need multiple reports, thus lowering the total cost of the Phase 1 ESA process.
What triggers a Phase 2 ESA?
Typically, a Phase II ESA includes sampling of one or more media including indoor air, soil, soil vapor and/or groundwater for contaminants or metals. The media and contaminants sampled and analyzed as part of a Phase II ESA are highly dependent on the historical use of the site.
Who pays for environmental assessment?
Buyer
Buyer pays unless the property comes back with Recognized Environmental Conditions (RECs) at which point the seller pays.
