How far should absorption lines be set back from bodies of water or impoundments?

1. 50 feet

2. 25 feet

3. 15 feet

4. 5 feet

The correct answer is: 50 feet

The optimal distance for setting back absorption lines from bodies of water or impoundments is 50 feet. This distance is recommended to ensure sufficient protection of water resources from potential contaminants. The 50-foot setback serves multiple purposes: it helps to minimize the risk of pollution from absorbed contaminants entering the water body, reduces the impact of excess moisture on the absorption lines, and helps maintain effective drainage and filtration within the surrounding soil. This buffer zone is crucial for preserving water quality and ensuring environmental compliance, particularly in residential and development projects. In contrast, shorter distances such as 25 feet, 15 feet, or 5 feet may not provide adequate protection, increasing the likelihood of contaminants reaching the waterbody. The further setback helps reinforce the health of water systems by allowing for more natural filtration through soil, which can be vital in maintaining ecosystem balance and safety for downstream uses.
