TCEQ GROUNDWATER C STUDY EXAMS GUIDE
QUESTIONS AND ANSWERS SURE A+
✔✔TCEQ - ✔✔Who do public water systems need to notify prior to making any system
changes or additions that result in an increase or decrease to the system's productions,
treatment, storage, pressure maintenance, or distribution facilities?
✔✔No - ✔✔Does the TCEQ require a permit to construct a new well?
✔✔Performed by lifting and dropping a heavy string of drilling tools into the bore hole.
The drill bit breaks or crushes material into fragments, which is mixed with water to
create a slurry, which must occasionally be removed. - ✔✔Cable Tool Drilling Method
✔✔Performed by using a chisel-shaped bit that shoots water. The water cleans the bit
and loosens the material. - ✔✔Jet Drilling Method
✔✔Performed only in unconsolidated formations having little or no rocky material. -
✔✔Driven Method
✔✔Performed for relatively shallow wells. - ✔✔Auger Boring Method
, ✔✔Performed using a compressor forcing air down the drill pipe. - ✔✔Air Rotary
Method
✔✔Most common method for drilling wells. - ✔✔Direct Rotary Drilling
✔✔Includes the other surface casing and the inner casing or blank liner. Must be new
carbon steel, high-strength low-alloy steel, stainless steel, or plastic conforming to
AWWA standards. Must extend upward at least 18 inches above the elevation of the
pump room. - ✔✔Well Casing
✔✔Prevents sand from entering the well. - ✔✔Well Screen
✔✔The simplest method of well development, pumping at a rate 15-25% higher than
normal service. - ✔✔Over-Pumping
✔✔Causes the well water to move in and out of the well by turning the pump on and off.
- ✔✔Backwashing
✔✔Operating a plunger up and down in the casing like a piston in a cylinder. -
✔✔Mechanical Surging
✔✔Performed by injecting air into the well. - ✔✔Air Surging
✔✔One of the most effective well development methods. - ✔✔Jetting
✔✔The level water stands in a well when the pump is off. - ✔✔Static Water Level
✔✔The level water stands in a well when the pump is on. - ✔✔Pumping Water Level
✔✔The difference between the static and pumping level. - ✔✔Drawdown
✔✔The volume of water per unit of time discharged from a well. - ✔✔Well Yield
✔✔The ability of material to release water from storage. - ✔✔Specific Yield
✔✔The well's yield per unit of drawdown. - ✔✔Specific Capacity
✔✔The depression in the groundwater table that develops around a pumping well. -
✔✔Cone of Depression
✔✔Wetted Tape, Air Line, Electric Sounder, and Electronic Sensor System -
✔✔Methods of Measuring Water Level
