Same here. In fact, I've been told by our Underground Geotechnical Investigation Unit to avoid certain areas at all costs to avoid running into the underground tank problem.
KATRINA SURVIVORS: "GUNS SAVED US" 2700An armed civil revolt may or may not be possible. However, the tanks and airstrikes would be fairly useless against such a spread-out enemy as the general population is. Are they going to call...
The cleanup problem happens when we end up purchasing either the building or the tank location itself. I've had projects where we did purchase land from a station with a contaminated soil problem and we did not have to clean up the area because he had a mitigation program already in action.
Yep. You can put in a sealed system all you like, but unless the entire drainage system is sealed, the contamination tends to find a way into it. NCDOT has avoided sealed systems unless there just isn't any other way to get the runoff to an outlet. I've seen 10' deep drainage boxes and counterflow systems (the boxes and pipes run opposite to the grade of the land above them) designed to stay out of contaminated areas.
That happens here too, but all too often the gas station owner promptly declares bankruptcy or just doesn't perform the necessary cleanup, and leaves NCDOT with the entire bill.
KATRINA SURVIVORS: "GUNS SAVED US" 2701Well, that's a shame, because I'd trust *all* my neighbors with semi-automatics. (It's likely that a quite a few have them, anyway.) And if any of them ever decided to betray that trust...
