Which entity recognizes soil series in Tennessee?

The correct answer identifies the Natural Resource Conservation Service (NRCS) as the entity that recognizes soil series in Tennessee. The NRCS plays a crucial role in soil conservation and management, and it develops and maintains soil surveys to help landowners and land managers understand soil types, limitations, and potential uses. These surveys are essential for making informed decisions regarding agriculture, land use, and septic system installation, ensuring that soil capabilities align with land use requirements.

The NRCS conducts extensive research and classification of soil types, which helps in determining the best practices for land management and environmental conservation. This organization is dedicated to supporting sustainable agricultural practices, including proper septic system placement, which is directly influenced by soil characteristics.

Other entities listed, such as the Environmental Protection Agency, Tennessee Department of Health, and Tennessee Valley Authority, focus on broader environmental regulations, public health, and energy production, respectively, rather than specifically recognizing soil series. Therefore, while they may intersect with issues related to land management and septic systems, they do not have the primary responsibility for soil classification in Tennessee. This distinction makes the NRCS the correct entity for recognizing soil series in the state.
