Pulled into my local gas station and found this golden nugget. Who would ever think u need a fuel servicing service. Definitely not the customer's but the owner does.
Just out of college, I worked a couple of years for a company in this field. This post brings back memories. When you have an underground fuel storage tank, if it leaks you have to clean up the contamination. Gas and oil have all kinds of toxic chemicals that can cause cancer. You really don't want that stuff in the water supply.
Someone has to dig out the tank and all the contaminated dirt. There's also a need to drill monitoring wells, only an inch across so you can drop down a glass vial to collect a water sample. Soil and water samples go to a lab for testing the amounts of hydrocarbons, benzene etc.
The soil's usually spread out in a thin layer to air out, occasionally flipped over and tested again. One of our clients mentioned something about Russian scientists who supposedly had invented a microbe can be sprinkled on dirt and it eats the petroleum. But I never heard anything more about that.
Reports have to go to the local government. If a gas station is sold, this is super important for the
real estate deal to go through.
This is a perfect "partly dirty" job or business, for someone who likes to play in the dirt with backhoes and bulldozers in all kinds of weather, who likes science, and who can put up with some government paperwork. The paperwork to track the samples is crucial. The government wants to be sure the lab measures the same water or dirt that was collected in the field. Super easy business to enter. Need is dictated by the local laws and the Department of Environmental Quality. Just make sure there aren't too many competitors close by.
Where I worked, the field crews had gloves and masks as needed. The scientists had gloves and powerful vent hoods. But in the office where I checked in samples and typed reports, there were no protective measures at all. I strongly believe this carelessness contributed to my cancer many years later. (Fortunately I recovered.) But there's no way to prove it. If you get into the field, I'd urge you to be super careful about not touching or breathing the contamination.
This would be a great area for a vertical market solution. Instead of signing off on paperwork in the mud and the rain (we often got the triplicate forms - for us, client, and government - in a big ziplock bag), a cell phone app could scan a barcode or QR label, timestamp the GPS location and include a photo or video clip when you take the sample and tape the label shut. At the lab, a barcode scanner could automate checking in the samples. There's some more that could be added, but I don't want to give away all my best ideas I might want to act on some day.
