Environmental Enlightenment #245

By Ami Adini - Issued July 15, 2018

This is a SHORT, LIGHT and SIMPLE newsletter. Its purpose is to rekindle in the initiated terminology they have once learned and enlighten the uninitiated on terms they may have heard but never known the meaning of.

Phase I Environmental Site Assessment
Probabilities and Possibilities


Probability is the extent to which something is probable; the likelihood of something happening or being the case. (Google)

Probability is a scale of certainty:

How probable it is that an undeveloped piece of land will be contaminated from spills of industrial hazardous substances?


A possible event is able to be done; it is within the power or capacity of someone or something, it can happen, can be done.

How possible it is for the soil in the above site to be contaminated with from spills of industrial hazardous substances?

Dump leaking drums on the land and watch!


Probability is a scale.

Possibility is yes or no.


While it is possible for a piece of land to be contaminated, the question remains as to how probable it is.


In Phase I environmental site assessments we deal with probabilities.

We research records, inspect the site, and arrive at an estimation of the probability for environmental infliction to have occurred.


Where we judge the probability to be beyond a certain degree of comfort, we move into Phase II: sampling of the soil, soil-vapor, or groundwater, to better ascertain that probability.


Because there are no absolutes, and because economics never justify sampling every inch of land, a degree of probability will always remain and enter our conclusions.

You can find past issues of our "Environmental Enlightenment" at amiadini.com Wealth of information about environmental site assessments in the real estate transactions and issues concerning assessment and cleanup of contamination in the subsurface soil and groundwater.

Call me if you have any questions. There are no obligations.
