Dig into the mystery of groundwater. Apart from sinkholes and caves, there are no underground lakes or rivers. Instead, water fills the voids in porous rocks below a certain depth, called the water table. Discover how wells are dug and why it’s a waste of money to hire a dowser, since water is practically everywhere if you dig deep enough. Also, consider the problem of groundwater pollution.
