Has anyone asked the school board for a copy of the remediation plan for the land? If someone can get information about what method of remediation they are planning on using that would be very helpful.
My bother-in-law does remediation for Batelle www.battelle.org/solutions/default.aspx?Nav_Area=Solution&Nav_SectionID=6&Nav_CatID=6_RemediationRestoration
He gave me a quick explanation as to how the remediation process works….said after they take the soil samples and determine what the land has been contaminated with, they have several options for remediation. There is something called a “dig and haul” method where you dig up the contaminated soil and haul it to a landfill. If the waste has been determined to be a hazard, it would have to go to a special hazardous waste landfill and this can jack up the price of the job. The Metea site is contaminated with diesel fuel, I think it is the concentration level that determines whether or not it is considered hazardous waste.
He went on to say that there are several different technologies (some better than others) to remediate the land and that the regulator may not allow a “dig and haul” - some states have stricter rules that others. One of the other methods of remediation is called “In-Situ soil remediation” whereby you bring the equipment to the site and clean the soil there. IIRC bioremediation is a process whereby oxygen is pumped into the soil and then microorganisms consume the fuel (something like that).
He said the job is divided into phases and there are many variables that determine how long it would take to complete such as - how large is the area of contamination – how long has the spill been there – and how cooperative are the contractors and agencies they one needs to deal with. Sounded like it involved a lot of red tape.
So the process is:
1)have the soil analyzed
2)have a plan for remediation drawn up
3)have the plan approved by some agency or the city (can’t remember)
4)do the remediation
5)have the land re-tested - if it fails, start over - if it passes get certification (shows that the land has been successfully remediated).
These are the basics. If you are interested in learning more, I have some reading material for you. My brother-in-law said he is working on a site right now that they thought could be remediated within two years – it is now ten years later and they still have not been successful with the remediation. Hope that doesn’t happen to us.
