Which monitoring approach is used for general area sampling with periodic checks?

• A. Nearside-Farside
• B. Boundary of contamination
• C. Area monitoring
• D. Course Leg

Answer: (C)

General area sampling with periodic checks is about surveying a broad space at regular intervals to watch how conditions change over time. This approach uses area monitoring: you set up multiple sampling points across a wide zone and revisit them on a schedule, giving you a broad, repeatable view of overall contamination levels and trends, not just a single spot.

The other approaches focus on specific boundaries or routes. Nearside-farside compares what’s on the near side versus the far side of a boundary to assess spread across that barrier. Boundary of contamination targets the edge of a known contaminated zone to delineate its extent. A course leg follows a predefined path or route, useful for mapping along a line or corridor rather than broad-area surveillance.

So, area monitoring is the best fit for general area sampling with periodic checks.
