Which local health department employee is qualified to conduct soil investigations?

The option indicating a person with three years of experience in approving systems, coupled with six hours of coursework in soils, is the qualified choice for conducting soil investigations. This is because the combination of extensive hands-on experience and formal education in soils equips the individual with the necessary knowledge and skills to effectively assess soil conditions.

Conducting soil investigations requires an understanding of various soil properties, drainage capabilities, and how these factors interact with septic systems. The requirement for three years of experience ensures that the individual has encountered a diverse range of soil types and conditions, leading to a deeper understanding of how each might impact sewage system performance. Additionally, the focused coursework on soils provides critical theoretical knowledge, ensuring that the individual is up-to-date on best practices and methodologies.

In contrast, options with less experience or education do not meet the necessary qualifications that ensure a comprehensive understanding of soil dynamics critical for sewage system approval and installation.
