During which week should compliance samples ideally be collected?

Collecting compliance samples during the first week is important for a few reasons. This timing allows for the early identification of any potential issues with water quality that could arise at the beginning of the monitoring period. By testing early, operators can implement corrective measures immediately if results indicate that the water does not meet required standards. This proactive approach helps ensure that any necessary adjustments can be made promptly, maintaining the safety and compliance of the water supply throughout the subsequent weeks.

In addition, starting with samples collected in the first week can help establish a baseline for comparison against future samples. It contributes to a more robust understanding of water quality trends over time and can also improve the facility's overall operational efficiency and regulatory compliance.

Collecting samples in the second or last week may not provide the same immediate feedback necessary for timely interventions, and suggesting that samples can be taken in any week does not reflect the preferred practice for ensuring water compliance and safety.
