Have you purchased a commercial or industrial building lately? If so, then you know the Minnesota Pollution Control Agency is aggressively regulating vapors that may seep into buildings. Cracks in concrete floors, holes in the foundations, and just plain porous concrete can be conduits for harmful chemical vapors that may exist from contamination on your property or even the neighbor’s property.
Environmental consultants are recommending vapor testing for sites that are near known
groundwater and soil contamination.
If the tests are positive, a second round of testing may be completed before designing a treatment system. Typical treatments include creating negative pressure under the floor slab and venting it out the roof. This can be expensive, $1.00-$2.00 per building square foot. As you may know, when the MPCA is concerned, so are the banks. We have worked on four transactions in the last two years that required vapor treatment. It did not stop the transactions, but the process takes time, effort, and attention to detail in order to be successful.
