The U.S. Geological Survey, tested the Ogallala Aquifer from Amarillo to Odessa. Water samples were taken from 48 wells in the region and tested for more than 240 constituents.
Of the constituents, 10 exceeded the U.S. Environmental Protection Agency's recommendation for drinking water. Some of the substances found were arsenic, fluoride, nitrate, radon and sulfate. But the good news is, the levels of these substances are no reason for concern, and most of them are caused naturally in water.
"Generally speaking I think people will be most interested in the fact that we didn't find many pesticides in the ground water, we did find a few at very low concentrations. These are in rural drinking water supplies," said Lynne Fahlquist, USGS Scientist .
Right now Lubbock gets only a small portion of its drinking water from the Ogallala Aquifer, and that area is not registering the high levels of constituents. If the Ogallala is eventually used as Lubbock's primary water source, the city will have to purchase a new pump system to treat the ground water.
