Groundwater use - Environmental geology outline

Water well construction:

• cost.
• drilling methods.
• components: casing, screening, gravel pack, bentonite seal, grouting, surface cover.

Pumping behavior:

• draw down cone - factors that determine geometry of?
• pump test, yield and transmissivity
• composite cones, and well fields

Concerns associated with intensive withdrawal:

• depletion case histories: case history in Chicago area, recharge rates, age of water.
• subsidence: causes, amounts, case histories (Houston area, San Joaquin in CA).
