The purpose of the sample siting plan is to assure bacteriological samples are taken from vacant houses.

• A. True
• B. False
• C. It ensures randomization
• D. It ensures sample quality

Answer: (B)

A sample siting plan sets where bacteriological samples should be collected in the distribution system to obtain a representative picture of water quality across the service area. It guides choosing appropriate testing locations (such as various customer taps and critical points in the network) to cover different conditions and avoid biased results. Taking samples from vacant houses is not the purpose of the siting plan; samples are collected from representative sites across the system, not specifically from vacant dwellings. The plan also isn’t primarily about randomization or guaranteeing sample quality—the latter comes from proper collection procedures, handling, and lab analysis, while the plan focuses on where to sample to reflect system conditions. So the statement is false.
