All routine coliform test results must be reported to the state by the tenth day of the following month.

• A. first
• B. fifth
• C. tenth
• D. fifteenth

Answer: (C)

Timeliness in reporting routine coliform test results is the key idea here. The required cutoff is the tenth day of the month following when the samples were collected. This keeps reporting aligned with a regular monthly cycle, giving the state current data to monitor water quality and take action if any issues show up. For example, January samples must be reported by February 10. The first, fifth, or fifteenth day do not align with this standard monthly reporting schedule.
