Regulations, Safety, and Business Practice
This domain tests the rules and job practices around pump installation: permits, well records, safety, contracts, and liability. The exam expects you to know that local requirements can be stricter than federal rules and that written documentation protects both the contractor and the customer.
Core rules and concepts
- Obtain required well and pump permits before work. Submit well logs and required reports. Follow state and local well-construction codes; they vary.
- OSHA rules apply to the jobsite: protective systems in trenches 5 ft or deeper unless stable rock, confined-space entry procedures, PPE, fall protection, and lockout/tagout.
- Keep contracts and change orders in writing. Define scope, payment, warranty, and exclusions. Maintain insurance and licensing.
- Handle water quality and disinfection according to regulations. Do not cross-connect a private well to a public supply without required protection.
- Document static level, pumping level, yield, pump setting, and test results.
Worked example
A crew is asked to set a pump in a 6-ft-deep trench alongside a well. Because the trench is 5 ft or deeper, a protective system such as sloping, shoring, or shielding is required unless the competent person documents stable rock. If the trench is in unstable soil, no worker enters until protection is in place. The 5-ft trigger is based on cave-in risk, not on how long the task takes.
Traps
Assuming verbal approval substitutes for a permit, skipping well logs, treating OSHA as optional, entering an unprotected trench, and relying on unwritten change orders are common failures.
