Ground water contaminants, like methane, arsenic, and salt may occur naturally in ground water. Ground water accounts for 95% of the liquid freshwater on Earth, but having enough accessible ground water can be a problem. Ground water typically moves slowly within the ground through porous rock layers like the sandstone.
