Drinking water monitoring plans (inventory/system and rules)

Back to drinking water forms for other rule specific forms or guidance

Use the table below to identify which sections of the monitoring plan are needed for your system. System and source type are located at the top of the monitoring schedule. The section for entry point disinfectant residual, chemicals, nitrate and nitrite, radionuclides, and bromate is part of inventory (there is not an individual section for these). General information is located below the table.

Monitoring plan inventory/system updates

Monitoring plan general information

  • Revisions
    • Water systems are required to submit any changes to us within thirty (30) calendar days following the effective date of the change. If submitting revisions please only submit the individual section(s) that changed.
  • Monitoring schedules
    • ​All routine monitoring information, facilities and sample points (with state assigned IDs), system classification, and system source classification is available at wqcdcompliance.com/schedules. Schedules are updated on a weekly basis and should be checked regularly for any changes.
  • Definitions and compliance calculations
    • General definitions and compliance calculations are listed at the beginning of Regulation 11. Specific definitions and compliance calculations are under each individual rule.
  • Process for re-evaluating sample points
    • Sample sites must be reviewed and updated to account for system changes (such as population growth, new sources, changes in treatment, or other significant changes). Systems must contact us before making system changes. Any changes related to the individual rule sampling plans must be sent to us within thirty (30) calendar days following the effective date of the change.
  • How to choose a laboratory
    • Laboratories must be certified for the specific method/analysis. Laboratories can be certified by the EPA or us. Please visit the laboratory services division for a list of certified laboratories. Samples must be collected/analyzed as described in Regulation 11 and according to the method. Contact certified laboratories for direction on sample containers, sample collection, and preservation.
    • In the event the lab is compositing samples for the water system, the system must notify us (prior to compositing) and the name of the laboratory used.
  • Reporting deadlines
    • Results of all required monitoring, for most rules, must be submitted to us within the first ten calendar days following the month in which the result is received, or within the first ten calendar days following the end of the required monitoring period, whichever is shorter. We issue monitoring and reporting violations based on adherence to these requirements.
    • Reporting may be done through the laboratory, but the system is ultimately responsible for ensuring that reports are received by us in a timely manner with all the required information.
