If you’ve ever had to hire an environmental consultant to investigate your property and collect samples, you’ve probably had to look at an analytical report from a laboratory and use it to answer some pretty important questions. Is there contamination on my property? What chemicals are present? How much is there? Most importantly, are the levels of contamination high enough to be causing harmful health effects? Only slightly less importantly, are they high enough to require a costly cleanup? You needed to know the answers to all of these questions so that you could sell or buy a property, get a business loan, or maybe just to sleep at night. With today’s trend of highly regulated vapor intrusion (VI) assessments being required at sites where dry cleaning with perchloroethene (PCE) has taken place, these questions have become increasingly important and more difficult to answer.
While there are challenges associated with environmental assessments of all kinds; determining the level of hazardous constituents in a building’s indoor air, assessing from where it may have come and evaluating if an unacceptable health risk exists for human occupants can be particularly delicate. For those property owners who need answers to the questions posed in the situation above, it is extremely important that samples of indoor air collected during VI assessments are representative of the air actually being breathed by the building’s occupants and that the laboratory results can be relied upon.

Many dry cleaners have expressed their desire to evaluate the soil and groundwater beneath their businesses for the presence of dry cleaning chemicals, but they are concerned that if they go through a cleanup, the property could be re-contaminated down the road.
Relax, the manner in which dry cleaning is conducted today is far more protective of the environment than it was even 30 years ago. For one, the machines designed and manufactured today are much safer than those of the past. Secondly, the safeguards employed today, including the installation of spill containment pans beneath machines and automatic shut-offs are protective of the environment. Finally, good housekeeping practices and the proper storage and disposal of spent solvent and filters today will greatly minimize the potential for spills and releases to enter the environment.

Why Won’t This Stuff Just Go Away?

Environmental cleanups are most often a complex undertaking with both soil and groundwater contamination. A certain amount of creativity is required to complete a site cleanup within acceptable timeframes, regulatory requirements, and of course, budget.
Ideally, once a cleanup begins, it ends when all contaminants have been removed. Sounds simple enough. Many times, cleanup projects start very well and appear to be heading toward closure (even under budget) but the cleanup appears to stop working.
Why did it stop working?

If you are currently considering purchasing a commercial property, expanding your existing business, or are in the market to sell your current business or commercial property, you have likely considered the lending opportunities available in today’s challenging economy. Borrowing options became limited as small business and business banking lending came to a near grinding halt in 2008. In September of this year, 13 major U.S. banks pledged to increase government-backed Small Business Administration (SBA) small business lending by $20 billion over the next three years in an attempt to stimulate the economy. In addition, local banks, regional banks, and even credit unions have begun taking advantage of SBA loan programs as a means of extending lending options to small business owners. If you choose to secure financing through an SBA loan program, you may face challenging environmental due diligence and environmental investigation requirements for your business venture.

Land Use And Geology As Hidden Variables

I am often asked by drycleaners how we will do the clean up and what will be the costs? It is almost always impossible to say at the onset because almost every situation is unique with a number of variables.
Environmental contamination from dry cleaning facilities is observed commonly. Historical spills and releases, from outdated machinery and outdated hazardous material handling practices are examples of the causes that may have impacted the soil and groundwater below such facilities.
Unfortunately, the amount of material released into the subsurface and the time duration during which it was released are not the sole indicators of the resources required to remediate the impacted media. The cost of cleanup is determined by a complicated combination of variables. For instance, if a gallon of Perc is spilled at Site A and at Site B, the cost of cleanup may be vastly greater at Site B based on the type of geology below the ground and/or the type of current use of the land at the surface.
