Records and reporting

The paperwork the exam actually tests

Records are not the glamorous part of the job, but they are the part that proves the water was safe and the rules were met, and the exam tests them at every grade. The questions are concrete: which records you keep, how long you hold them, when reports are due, and how fast you tell the public when something goes wrong.

What you keep, and for how long

The rules set retention periods, and the exam likes the differences between them. Bacteriological results are kept for at least five years. Chemical analysis results are kept for at least ten years. Records of sanitary surveys and of actions taken to correct violations are held for several years as well. Confirm the exact period against the current rule, since they are set by regulation and the question wants the right number, not a guess. The point underneath the numbers is that a record proves compliance only if it still exists when someone asks.

The compliance calendar

A monitoring schedule, often called the compliance calendar, is the operator's map of what sample is due when: the routine bacteriological samples, the chemical monitoring on its longer cycle, the disinfection and turbidity readings taken every day. Missing a required sample is itself a violation, a monitoring violation, even when the water was fine. The calendar is how a one-person system keeps from missing one.

Reporting to the state

The state is the primacy agency that runs the drinking water program, and the operator reports to it on a schedule: the monthly operating report, and a prompt report whenever a result exceeds a limit or a required step is missed. The reporting window is set by the rule and is often short for a serious result, so knowing the clock matters as much as knowing the limit.

The public-notification clocks

When a problem puts people at risk, the operator notifies the public on a tiered clock. Tier 1 is for an acute risk and goes out within 24 hours, Tier 2 for a non-acute one within 30 days. Tier 3 is the annual notice, delivered through the Consumer Confidence Report, the yearly water-quality report to customers. The yearly report is far too slow to be that notice.

Where operators lose points

• mixing up the retention periods; bacteriological is shorter, chemical is longer
• forgetting that a missed sample is a monitoring violation on its own
• confusing the public-notice tiers; 24 hours for acute, 30 days for non-acute
• treating the annual Consumer Confidence Report as notice for an urgent problem

Quick reference

• Keep bacteriological results at least five years, chemical results at least ten years (confirm against the rule).
• The compliance calendar drives monitoring; a missed required sample is a violation by itself.
• Report to the primacy agency on schedule, and promptly when a limit is exceeded.
• Public notice: Tier 1 within 24 hours (acute), Tier 2 within 30 days, Tier 3 the annual Consumer Confidence Report.

Where this fits
