Mike and Nancy Leighton’s problems began on May 19, just as Mike was settling in to watch the Preakness Stakes. A neighbor in Leroy Township, Pa., called Mike and told him to check the water well located just outside his front door. Typically, there’s between 80 to 100 feet of headspace between the top of the well and its water supply. But when Leighton went outside, the water was bubbling over the top.
