Louisiana (LA) 4-32 Water Well Drilling Contractor Exam
150 High-Yield Practice Questions, Verified Answers, and
Technical Rationales | INSTANT PDF DOWNLOAD
This comprehensive study resource is specifically engineered for professionals preparing for the Louisiana State
Licensing Board for Contractors (LSLBC) specialty trade exam. It covers the technical, legal, and environmental
standards required to operate as a licensed water well contractor in the state of Louisiana.
Introduction to the 4-32 Classification
The 4-32 Water Well Drilling license is a critical credential for ensuring the safety and sustainability of Louisiana’s
groundwater resources. Candidates are tested on their ability to design, drill, and maintain wells while strictly
adhering to the Louisiana Department of Natural Resources (LDNR) and Department of Health
(LDH) regulations.
Core Study Domains Included:
Louisiana State Regulations: Well registration deadlines, abandonment procedures, and driller licensing
requirements.
Well Construction Standards: Casing specifications (Schedule 40/80), grout seal requirements (Neat
Cement/Bentonite), and annular space sizing.
Hydrogeology & Hydraulics: Aquifer characteristics (Confined vs. Unconfined), drawdown calculations, and
Specific Capacity (GPM/ft).
Pump Systems & Installation: Submersible vs. Jet pumps, pressure tank sizing, and Pitless Adapter configurations.
Sanitation & Safety: Shock chlorination protocols, setback distances from contamination sources (septic
tanks/cemeteries), and rig safety near power lines.
, 1. According to Louisiana Title 56, how many days after completion does a driller have to
submit a "Well Registration" form?
A) 15 days
B) 30 days
C) 45 days
D) 60 days
Explanation: Louisiana Department of Natural Resources (LDNR) regulations
require all new, altered, or reconstructed wells to be registered within 30 days of
completion.
2. What is the minimum required distance between a domestic water well and a
septic tank in Louisiana?
A) 25 feet
B) 50 feet
C) 75 feet
D) 100 feet
Explanation: To prevent bacterial contamination, Louisiana sanitary codes
mandate a minimum 50-foot buffer between a well and a septic tank.
3. Which state agency oversees the licensing of Water Well Drillers in Louisiana?
A) Department of Natural Resources (LDNR)
B) Department of Environmental Quality (LDEQ)
C) Department of Health (LDH)
D) State Licensing Board for Contractors (LSLBC)
Explanation: While LSLBC handles the business license, the LDNR Office of
Conservation regulates the technical driller's license and well standards.
4. An "Artesian Well" is defined as a well where:
A) Water rises above the top of the aquifer under natural pressure
B) The water must be pumped from great depths
C) The water is always boiling
D) The well is drilled into a salt dome
Explanation: Artesian conditions occur when an aquifer is confined between
impermeable layers, creating enough pressure to push water up the borehole.
