Monitoring and Compliance · Sampling Plans
How Is a Drinking Water Sampling Plan Built?
A sampling plan turns requirements into repeatable work. For each sample point it lists the purpose, analyte, frequency or event trigger, approved method, and responsible role. It also lists the lab, container, preservation, holding time, and required record.
The plan should separate regulatory samples from operational samples. Both matter. But a handy operational tap may not be an approved compliance location. An operational instrument may not use the method required for reporting.
Review the plan when sources, treatment, schedules, sample taps, labs, rules, or state directions change. A map and current point names keep staff from relying on memory or an old name.
Before a monitoring period begins, confirm supplies, lab hours, shipping, trained backup collectors, and escalation contacts. A plan that only sits in a binder does not prevent a missed sample.
Key point: A usable sampling plan assigns the right location, method, timing, lab, records, and owner before the sample is due.
