Billions of gallons of wastewater are produced when oil and gas shale wells are drilled. According to Bloomberg, wastewater is now being used for crops in drought-stricken California instead of being injected into disposal wells. Companies are selling the water to farms in need of it or recycling it.

In 2014, Chevron piped 8 billion gallons of treated wastewater to almond and pistachio farms in the San Joaquin Valley. Earlier this year, California Resources Corp. said it intends to quadruple the amount of water it sells to growers.

Companies choosing to recycle the wastewater and use it again for wells have discovered that less expensive and extensive treatment makes the wastewater suitable for drilling.
