More than 180,000 gallons of crude oil was spilled when the world's worst landscaper ran over a 72 year old oil line with a lawnmower.

The puncture was small and the pressure in the line was high. The reversal of the US' oil export ban in 2015 has led to an increase in pressurization. Oil companies are pushing more products with little government oversight.

When there is a catastrophic accident, most of these companies are self- reporting, self-regulating, and we only see the intervention of federal agencies.

Big Impact

The EPA recovered 75 percent of the oil that was spilled.

The turtles killed by the spill received small solace. Although the EPA report was short on details, it found that fish, land animals and more were affected by the oil.

Next to the Memphis Sand Aquifer is where the spill happened. Although the public wasn't affected, the Tennessee Department of Environment and Conservation is watching the water.

The researchers are still finding residuals from the massive 2010 oil spill.
