There are literally billions of gallons of water used every day in extracting oil and natural gas from the earth. The onset of new fracking techniques has only accelerated the use of water by the energy industry. Fracking has also put a spotlight on the importance of the safe treatment of the water used to ensure environmental health.

The only company focusing all of its energy on meeting the needs of this booming industry is Nuverra Environmental Services (NESC). Formerly known as Heckmann, the company has spent the last few years building out its infrastructure to seamlessly handle the energy industry's water demands.

Motley Fool contributor Brian Stoffel is currently considering Nuverra as one of the five stocks to buy in June for his Roth IRA. He's been calling out one company per month for almost two years now, and the portfolio has returned 25%, beating the S&P 500 by over four percentage points.

In this video, Brian lays out his case for investing with Nuverra.
