A discussion of one of the major types of water pollution follows including its effects on human health & how to deal with it.
One of the causes of water pollution & contamination is gasoline, which industrialized countries are awash in. We use a lot of gasoline. When it seeps or leaks into our environment it contaminates water intended for our use.
It only takes a gallon of gasoline to make 5 million gallons of drinking water unfit for human use.
There are many thousands of underground gasoline storage tanks that are beyond their 20 year life expectancy as secure gasoline containers. The Leaking Underground Storage Tanks Program suggests there may be hundreds of thousands such tanks in the U.S. alone.
Another of the main causes water pollution is MTBE, a gasoline additive that has been used since 1980.
MTBE is intended to limit air pollution that gasoline causes.
Unfortunately, experiments have linked MTBE to cancers in lab animals.
Furthermore, MTBE cannot simply be safely absorbed by the environment. It is not biodegradable & so will lead to water contamination for the foreseeable future.
The issue of gasoline & MTBE has, not surprisingly, become political now.
Oil companies reportedly knew that MTBE was a debilitating water pollutant but pushed for its adoption anyway. Now there is a political tug o’ war between those pushing for oil companies assuming responsibility for the effects of MTBE & those pushing for complete absolution of any responsibility on the part of oil companies.
Meanwhile, millions of citizens have been exposed to gasoline & MTBE with no end in sight.
Dozens of communities are using contaminated water, polluted with MTBE even while more lawsuits demanding clean up of this water contamination are working their way through the court systems.
Still, detections of MTBE used in gasoline are increasing throughout the U.S. Contamination has been found in roughly 2,000 water systems in 30 or more states. Upwards of 50 million Americans are affected by this problem.
