Seville native Rebecca Quintana shows a water line that provides part of Seville with household water from the town’s nearby pump. The plastic pipe replaced a rusty pipe that Quintana says may have dated back to the early 1900s. Both pipes are in an irrigation ditch with standing, fetid water. Quintana wonders if the water had anything to do with the May 2015 death of her daughter Regina Lujan. Breast cancer caused Lujan’s death.
