Texas Water Well Regulations Practice Exam 2026 |
Verified Answers | Exam Prep
1. If a new well was disinfected for only 3 hours instead of the required time,
what potential risks could arise regarding water quality?
No impact on water quality
Improved water taste
Increased risk of bacterial contamination
Enhanced mineral content in water
2. If a water treatment facility is experiencing low oxygen levels in its treated
water, which aeration method might be most effective to implement and
why?
Packed-Tower, since it is the most cost-effective option.
Forced Draft, because it actively increases oxygen transfer rates.
Natural Draft, as it is the simplest method and requires no additional
energy.
Induced Draft, because it is the most commonly used method in all
facilities.
3. In a scenario where a well is experiencing water quality issues, how might an
acoustic log be utilized to address the problem?
To assess the integrity of the well casing and identify potential
pathways for contamination.
To measure the temperature of the groundwater.
To analyze the chemical composition of the water.
To determine the depth of the water table.
,4. What is the minimum number of connections a system must have to be
classified as a Public Water System?
10 connections
15 connections
20 connections
25 connections
5. If a water treatment facility is experiencing high levels of organic
contaminants, which oxidizing chemical would be most effective for
treatment?
Ozone
Chlorine Dioxide
Potassium Permanganate
Chlorine
6. Which agency is responsible for overseeing public water supplies in Texas?
TPWD (Texas Parks and Wildlife Department)
TWDB (Texas Water Development Board)
EPA (Environmental Protection Agency)
TCEQ (Texas Commission on Environmental Quality)
7. Describe the significance of the Auger Boring Method in the context of Texas
water well regulations.
The Auger Boring Method is primarily used for deep well construction
and is not regulated by Texas law.
, The Auger Boring Method is significant as it is specifically suited for
constructing relatively shallow wells, ensuring compliance with state
regulations.
The Auger Boring Method is used exclusively for water quality testing
rather than well construction.
The Auger Boring Method is a technique that does not require any
regulatory compliance in Texas.
8. If a new animal feedlot is proposed to be built 400 feet from an existing well,
what regulatory action should be taken?
The proposal should be denied due to the proximity to the well,
which violates regulations.
The proposal should be approved with no restrictions.
The proposal can proceed with additional water quality testing.
The proposal can proceed if the feedlot is covered.
9. Underground fuel tanks and septic dranage fields must be at least feet
from a public well.
1,500
15,000
15
150
10. Describe the role of oxidizing chemicals in water treatment processes.
Oxidizing chemicals are used to add minerals to water.
Oxidizing chemicals are used to disinfect water and remove
contaminants by breaking down organic materials.
, Oxidizing chemicals are used to increase the pH level of water.
Oxidizing chemicals are primarily used to enhance the taste of water.
11. What is the term used to describe the process of operating a plunger up and
down in the casing like a piston in a cylinder?
Well Development
Hydraulic Fracturing
Mechanical Surging
Water Testing
12. Describe the principle behind electrical resistivity testing in geophysical
studies.
Electrical resistivity testing is used to determine the temperature of
groundwater.
Electrical resistivity testing assesses the chemical composition of
water in wells.
Electrical resistivity testing involves measuring the magnetic fields
generated by subsurface materials.
Electrical resistivity testing measures the resistance of subsurface
materials to electrical current, which helps identify different
geological formations.
13. The performance of a well is measured by its.
Permeability coefficient
Storage coefficient
Specific yield
Specific capacity
