eventually reaching a “wellhead” or water intake.

Zones: This
illustration demonstrates that the land around
a wellhead or water intake may be vulnerable to
contamination. This shows multiple sources of
contamination moving through the ground and being
drawn in by a well.
A source of contamination may pose a greater risk
to drinking water the closer it is to the wellhead.
Contamination may pose a greater risk if it is
able to move quickly through some substances.
For example, sand is more porous than hard-packed
clay and could allow contamination to move through
it more quickly.
