Question

Minimum distance between well and source of contamination should be at least:

• A. 500 meter
• B. 50 feet
• C. 15 meter
• D. 100 feet

Hint:

Safe well = 100 feet from contamination source — keep your water clean!

Answer 1

The Correct Option is D

According to standard public health guidelines and recommendations under rural water supply schemes, the minimum safe distance between a drinking water well and any source of contamination (like soak pits, septic tanks, or drains) should be at least 15 to 30 meters or approximately 50 to 100 feet.
Practically, the minimum recommended is about 100 feet to ensure groundwater is not easily contaminated by seepage from nearby waste sources.
Therefore, option (4) — 100 feet — is the correct answer.
