True or False: All repeat samples must be collected on successive days.

The statement is false because not all repeat samples must be collected on successive days. In fact, the guidelines for sampling frequency can allow for repeat samples to be taken at different intervals, depending on the type of sampling being conducted and the regulations in place. For example, routine monitoring may allow for repeat sampling within a specified timeframe that does not require consecutive days, as long as the overall sampling schedule is adhered to. This flexibility is important for accommodating practical considerations within water testing and monitoring procedures.

Understanding this is crucial for water operators, as it affects how they plan and execute sampling schedules to ensure compliance with health and safety regulations. In certain circumstances, such as when monitoring for contaminants or responding to a potential pollution event, the timing and frequency of repeat samples may need to be adjusted. Therefore, operators must be familiar with the specific requirements dictated by the Texas Commission on Environmental Quality and other governing bodies, rather than assuming that consecutive daily sampling is a blanket requirement for all repeat samples.
