What Lies Beneath Your House

Do you know what lies buried beneath your back yard?

I was recently looking through some old nineteenth century maps of my neighborhood and discovered that the land upon which my home was built used to house a large chemical works factory. I've now had second thoughts about that vegetable patch I've always planned to plant.

There are nearly one million chemical spill sites in the United States. Who knows what other environmental hazards lies beneath the ground in your neighborhood?
