Old Gas Stations and Leaking Tanks a bad situation
When I asked a neighbor up at the radio station about it he told me the EPA had shut the station down and ordered the underground storage tanks emptied because they where leaking.
This is a big problem in rural areas with mostly old independently owned stations where owners do not have the funds needed to upgrade there tanks and pumps which runs into the tens of thousands of dollars.
Unlike major branded stations which have the resources to handle it.
Which includes digging up and removing the tanks and any contaminated soil.
New tanks if allowed underground must meet all kinds of special rules to prevent leaks and contaminating the ground water such as special liners and leak alarms. This is why you will often see tanks are now above ground with barriers around them as it is very expensive to bury them for use.
You might notice all modern repair garages have there servicing lifts installed above ground now for same reason to prevent hydraulic oil from leaking into the ground. A tank leaking above ground can be spotted much faster and leak cleaned up much easier than when its underground.
The problem since fuel is lighter than water one single tank leak can contaminate soil and water for several hundred acres around it poisoning wells and those who consume the water.
In Chucks case he sits on a hill above the Kiski River. His tanks leaking could well end up in the river if they where not stopped from pumping gas.
A few years back in Pittsburgh's North Side a developer ran into a major problem when he ran into ground which was contaminated in the 1930's when a gas station once sat there. Soil had to be removed and area sealed before work could begin.
Since water well design and construction in Pa. has no regulations gas station leaks are a major concern because if wells are not sealed properly they can be easily contaminated.
This is one of the on going fights with gas wells being done with fracing many people claim the well has contaminated there water when clearly 70% of all wells tested in many areas before drilling even starts where already contaminated by various chemicals and pollutants from past industrial activity's such as shallow gas and oil wells, coal mines, chemical and industrial plants etc.
Even the well at radio station I take care of is not consumable because although there was no industrial activity all the chemicals and pesticides used over all the years when it was a farm have made it into the water table.
