Is the statement true: No source of contamination is allowed within 500 feet of a public well?

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (B)

The concept being tested is wellhead protection: the area around a public water supply well where safeguards are put in place to reduce contamination risk. A 500-foot radius is a common guideline used to illustrate this protection zone. But the statement that no source of contamination is allowed within that distance is not accurate. The goal of the protection zone is to minimize risk, not to ban every potential contamination source outright. Within this area, activities and facilities are regulated and often required to have containment, spill prevention, or particular design measures to prevent contamination from reaching the aquifer. Some sources may be allowed if they meet these safeguards, and exposure to contamination can still be managed through proper construction, monitoring, and regulatory controls. So the statement is false because a 500-foot protection area does not equate to an absolute prohibition on all contamination sources.
