What to do about a house in Washington County
No soluble bedrock is mapped here, so natural sinkholes are unlikely. Collapses from broken pipes or old mines are a separate risk.
Across 724 square miles, under one square mile of Washington County maps onto soluble rock. With about 41,181 residents (57 per square mile), much of the land is open, and the mapped rock may sit far from where people actually live. The figures come from 282 map points about 1.6 miles apart, so a pocket smaller than that can be missed or overstated.
