We know what you’re thinking: How does the US get its clean drinking-water from its own reservoirs?
We asked the US Geological Survey.
The answer, we learned, is by drinking the water.
This isn’t an entirely new idea: In the early 2000s, we talked to scientists at the University of California, Berkeley, and at the Lawrence Berkeley National Laboratory, about the role of the Earth’s groundwater, which provides the bedrock for most of the world’s food and water supplies.
It also provides about a quarter of the water we drink in the US, according to the Department of Energy.
The problem is that most of that groundwater is underground, underground that we can’t see.
It is underground that is contaminated with other pollutants, and that’s where most of our contamination comes from, according the USGS.
In the early 1900s, people started to worry about groundwater contamination.
A few years later, in the 1930s, there was a major drought.
The government issued a statement warning that we could expect more droughts in the future, and a number of states started to do some groundwater pumping.
And then, of course, there’s the water issue, which has always been a concern.
In many rural areas, water supplies are limited by geography.
For example, the state of Kansas doesn’t have a lot of natural springs.
So if you’re a farmer in that area, you’re not going to get water for your crops from springs.
Instead, the crops are irrigated by groundwater, so you get water from your aquifer, which is not well drilled.
There are lots of factors that come into play in rural water systems, and the USG has found that the main ones are geography, geography, and geography.
The biggest one is elevation.
People are living in hills, which means there are more natural springs than valleys, and therefore, there are bigger potential springs for groundwater contamination, the USGs research shows.
And that’s a major problem.
Another problem is temperature.
As temperatures go up, there is more groundwater contamination because of the warmer temperatures, and you can’t pump it out.
And you can see that in places like New Mexico, which doesn’t get much rainfall because it has mountains.
So you’re going to see that we’re going back to more of the same problems that we had in the past, and maybe even worse, as the seasons change, said Robert Stearns, the director of the US Geosciences Institute.
The USGS has found the biggest threat in the rural areas is from groundwater contamination caused by poor disposal practices.
That is, people are using the groundwater for drinking water when they shouldn’t, and not putting it out in a way that will keep it clean.
This is not a situation that is unique to the US.
In some parts of the globe, the water systems that are in place in those areas are also poorly managed, so people can get contaminants from the surface water, which they can get into the ground, and then it’s a long way to get it out of the ground.
Stearns said that the US should do more to make sure that the people in those places are taking these steps.
The most important thing to understand about groundwater is that it’s not just one resource.
It’s all of these resources that we all use in a variety of ways, from transportation to energy.
We use them to create and maintain our infrastructure, to provide services to our customers.
In fact, it is the natural state of things that we depend on water for.
And the more people are relying on groundwater to get their water, the more we have to worry.
And the more water we rely on groundwater, the higher the likelihood of water contamination.
