U.S. Navy Petty Officer 2nd Class Michael Mathews helps to set up a grey water sanitation soakage pit during Preventative Medicine Exercise 2016 at Camp Pendleton, Calif., Nov. 10, 2016. The pit is 5 feet long, 5 feet wide, and 5 feet deep filled with small rocks and pipes to safely transfer waste to the ground.
