Last month the California Environmental Protection Agency (Cal/EPA) hosted two Vapor Intrusion Workshops.  While we recognize that not all of the readers care about more strict California regulations being handed out, in the environmental world regulations and technology coming from California usually creeps across the country to other states like ivy on a tree.  The workshops were held for Cal/EPA staff and other stakeholders, which were predominately environmental consultants.  John Bird, Vice President of EnviroForensics’, and one of the foremost leaders on vapor intrusion issues with over 12 years of hands on experience, was there to report on pending issues and new developments.  Not so ironically, out of the seven (7) projects that were presented by Cal/EPA during the workshops, two (2) were projects that John served as lead scientist.

Many drycleaners have always followed the law and managed a clean and respectable business, but they later find out that the rules they had followed for years have become more stringent. Other drycleaners would like to eventually pass the business on to their children but are afraid of handing them an environmental liability.

Although the March 1992 report looked at other industries as potential sources of perchloroethylene (PCE) groundwater contamination, it concentrated its investigation on dry cleaners.

In past articles, we discussed the difference between Phase I and Phase II investigations.  A Phase I generally refers to a due diligence evaluation that address the past land uses of a property or group of properties.  A Phase II generally includes an initial or preliminary investigation to determine whether or not the soil, soil gas or groundwater beneath the subject site is contaminated with metals, petroleum hydrocarbons, chlorinated hydrocarbons (solvents) or other chemicals of concern, based on the past land uses.

Selecting a remedial technology could be the most important decision you could make.  So how does one go about selecting a cleanup approach and what factors come into play?  The effectiveness of any cleanup technology is dependant on the chemicals being remediated (petroleum or perchloroethylene), the chemical concentrations, the geologic or stratigraphic setting of the Site, the depth to groundwater and whether or not groundwater is impacted and will need to be remediated.  If anyone tells you that they can cleanup contamination without knowing the specifics of the site, be very cautious of that individual.
