Answer:
nitrates; cone of depression; confined; water table; unconfined; drainage field; spring.
Explanation:
Nitrogen-fixing bacteria in soil can convert excess nitrogen into nitrates, which can contaminate groundwater.
A cone of depression forms around a well when the water table begins to slope toward the well.
The water in an artesian well comes from a confined aquifer.
A well not only has to reach the water table but also has to go deeper.
Unconfined aquifers are more prone to pollution.
The two primary components of a septic system are a septic tank and a drainage field.
Groundwater that comes to the surface naturally is spring.

Nitrogen fixation may be defined as a process that involves the conversion of atmospheric nitrogen (N2) into ammonia (NH3) or ammonium ions (NH4+).
