| CASE STUDIES: SQUEEZING
A LOT OF HELP INTO A LITTLE BIT OF SPACE. |
|
| With one mobile trailer in one parking
space, Letterle successfully remediated a small urban lot in Charleroi,
Pennsylvania. |
|
| What happens when you combine a leaking
underground storage tank with a crowded urban environment, an asphalt
surface, underground and overhead utilities, and an anxious third-party
owner who doesn’t want to have his business disrupted? |
|
| You get the kind of challenge that we faced in Charleroi, Pennsylvania. |
|
| The previous owners of the underground storage system at the site
asked us to determine the impact of a petroleum release on soil and
groundwater beneath the site – no small feat given such challenging
parameters. Yet we were able to drill and install a network of monitor
wells during the site characterization. |
|
| And that was just the beginning of the challenge. When we discovered
elevated concentrations of unleaded gasoline compounds at the site,
remediation was necessary. And so was some creative thinking. |
|
 |
|
| Typically, remediation systems at service stations and petroleum distribution
facilities are housed in a permanent storage shed built on-site. However,
due to the previously mentioned constraints, this was not possible.
That’s when we came up with a great idea -- install the remediation
equipment in an enclosed mobile trailer, which would occupy a space
equivalent in size to that of a single parking space. |
|
| The approach worked wonders and satisfied all parties involved –
the former tank system owner, the property owner and the regulatory
agency. |
|
|
|
| In less than two years, the contaminant concentrations
in groundwater have been reduced by 96% -- with a minimum of space,
time and disruption. |
