Which distance requirement is essential to prevent contamination from soil absorption systems to public water supply lines?

• A. 7 feet
• B. 10 feet
• C. 15 feet
• D. 20 feet

Answer: (B)

The essential distance requirement to prevent contamination from soil absorption systems to public water supply lines is 10 feet. This distance is based on regulations intended to safeguard public health by ensuring that any potential contaminants from septic systems or similar installations do not easily migrate to where drinking water sources are located. The 10-foot separation is considered adequate to allow for natural filtration and the degradation of pollutants in the soil, helping to protect the integrity of the public water supply. While greater distances may further reduce risk, the established norm of 10 feet effectively balances practical installation considerations with health protection requirements. Other options, such as 7 feet, 15 feet, or 20 feet, may not be the standard threshold outlined in regulations, demonstrating that proper knowledge of these requirements is crucial for compliance and safety in public health contexts.
