The correct choice reflects a critical aspect of maintaining water quality standards under the Revised Total Coliform Rule (RTCR). A Level 2 assessment is prompted when a water system has two Level 1 assessments within a rolling 12-month period. This requirement is in place because it indicates a consistent pattern of potential contamination or system issues that warrant a deeper investigation to ensure the safety of the water supply.

This Level 2 assessment is more comprehensive than the Level 1 assessment and is designed to identify and address potential causes of fecal contamination in the distribution system. By requiring this trigger, the RTCR ensures that water systems are held accountable for managing risks and taking corrective actions where necessary.

In contrast, other options discuss scenarios that don't necessitate a Level 2 assessment. For instance, a single total coliform-positive (TC+) sample does not automatically indicate a serious systemic issue, but rather may warrant a Level 1 assessment. Similarly, successfully completing all required samples or a passing inspection for a seasonal system demonstrates compliance without the need for an advanced assessment. These scenarios reflect routine operational practices rather than recurring deficiencies that would trigger a closer examination of the system.
