Show answer & explanationAnswer & explanation
Correct answer: D. Consult with a local building department or county health department for records.
Before any excavation or disturbance, locating a septic system is critical. The most cost-effective and reliable initial step is to check public records, which often contain permits and 'as-built' drawings of septic system locations. This avoids unnecessary costs and potential damage.
Why the other options are wrong
- A. While GPR is effective, it's a specialized service and often an expense. It should be considered if records are unavailable or insufficient, not as the first step.
- B. Asking the client to dig is unprofessional, potentially dangerous, and shifts liability incorrectly.
- C. Assuming the location is incorrect and could lead to severe damage and environmental hazards.
