The vital role of Phase 2 Environmental Site Assessment

The Phase 2 environmental site assessment is the investigation perform whenever you have a reason to believe there is a bit of contamination on the site and requires establishing the occurrence of the contaminations. It means that phase 2 ESA is discover during Phase 1 ESA.

Phase II ESA note phase I led to some suspicion about the location or site issues. The recommendations for phase 2 never mean that there is any kind of contamination with the reason for suspecting their existence, and it mainly forms the entire due diligence.

Performance for Phase 2 ESA

Generally, the phase II ESA is overseen by the professional geologists working with the entire team of professionals, engineers, and ESA providers. They may have to consult with the whole state or even the Tribal Brownfield Programs across various states having the activities through the assessments that involve the specific circumstances.

The geologists start to check out the reports of Phase I while using the designs across the environmental site assessment that considers these contaminants likely to present the property’s history.

Different kinds of Phase II ESA

Knowing the kind of phase two ESA with the different types is essential.

Generally, three different forms of phase 2 ESA are perform base on the outcomes of the phase 1 assessments. The geologists start to determine the likelihood of the necessities. Let us now check out the different types of site assessments.

  • Vapour: The specific concern across the several Brownfield sites is the existence of the vapour that may start to intrude into the existing buildings. The vapour intrusions often get consider a connection to the natural radon that needs mitigation of the system. But, there are a few specific chemical contaminants that cause intrusion of water vapour, and it is the type of chemicals that geologists get concern with:
  • Volatile Organic Compounds (VOCs): Several VOCs are emitted from the sources within the vacant building, including the paints and building materials.
  • Semi-Volatile Organic Compounds: They are mainly discovered on sites used by manufacturing industries and even agrochemical plants.
  • Elemental Mercury: A few specific pesticides become a problem when the site is used for intensive agriculture.
  • Polychlorinated Biphenyls: For more, the intrusion of vapour is a massive concern concerning the demolition of the buildings earlier or even in the sites where they are used in manufacturing.


Contamination of soil is extremely common here. Soil testing becomes the essential part of environmental site assessment where you require experience from the phase 2 provider who can help you test the samples.

It involves obtaining permits for drilling into the soil and taking discrete samples. These soil samples reveal not just the presence of the contamination but even the location.


Several sites need the sampling of the groundwater, although the extent of it becomes necessary depending on the underlying geology and the watershed. The groundwater samples derived out of drilling get studied in the lab.

It involves initial assessments of the depths of the groundwater on site so that the right kind of sampling is taking. Groundwater gets contaminate easily with metals, petroleum, and more. There are other techniques that, at times, are use to sample the soils regarding groundwater depths instead of water.

Surveys are perform to establish the likelihood of the groundwater with the geologists considering the groundwater flowing into and out of the site. The upstream contaminations from the other site common in the areas are heavily develop.

In several instances, a few others may work. For instance, an updated site survey requires establishing the ideal sampling locations. There are radiological surveys through the sites that get perform.

After the necessary assessments are complete, there are geologists prepare the reports. It takes into account the planned use of the land itself. There are greater standards for the residential development becoming firmer than for the commercial premises as it is vital to have the diligent phase 2 provider performing these assessments.

Concluding thoughts

You may get concern about the phase 2 environmental site assessment resulting in delay construction or, even worse, while the site is rule unsuitable for use. It makes them tempted to perform about one or two of these assessments. It even arrives from the lack of understanding about the phase 2 site assessments and the way it helps your project safely progress. 

The phase II ESAs arrives with the environmental risks adversely affecting the real estate transactions. It sometimes concerns one; however, a reason doesn’t need to walk off the deal. It is vital to perform one to ensure safety, avoid any liability, and understand the phase two ESA and its great importance; however, these are the risks that are consider the inherent portion of the development of Brownfields.

It is note for the vital role of the phase II Environmental Site assessments through extensive research.
