Introduction Continued
  • Monthly Operator Reports serve several functions
      • Primary function is it provides a way to track effectiveness of the filtration and disinfection system.
      • Provides a record of daily operational readings.
      • A means of reporting to DEC that all regulatory requirements have been met.

  • Different Types of Operator Reports
    • Conventional or Direct Filtration
      • 3 or more filters
      • Less than 3 filters
    • Alternate Filtration, Slow Sand, or Diatomaceous Earth
      • Standard report
      • Reduced Monitoring

turbidity reporting requirements
Turbidity Reporting Requirements
  • Combined filter effluent (CFE) turbidity measurements
    • Taken after the point where all individual filter effluents combine.
    • Turbidity measurements are taken from grab samples or online turbidimeter recordings taken at four hour intervals.
    • Recorded on first page of operator report.
turbidity reporting requirements continued
Turbidity Reporting Requirements Continued
  • CFE turbidity requirements
    • 95% of all CFE turbidity measurements taken during the month must be less than or equal to:
      • 0.3 NTU for Conventional and Direct filtration plants
      • 1.49 NTU for Alternative, Slow Sand, & Diatomaceous Earth plants
turbidity reporting requirements continued1
Turbidity Reporting Requirements Continued
  • Maximum CFE Turbidity limits:
    • 1.49 NTU for Conventional and Direct plants
    • 5 NTU for Alternative, Slow Sand, & Diatomaceous Earth plants
  • Must notify DEC within 24 hours if maximum CFE limit is exceeded.
    • Document on Page 2 of operator report.

entry point chlorine reporting requirements
Entry Point Chlorine Reporting Requirements
  • Residual readings collected daily at entry point to the distribution system
    • Sampling frequency is based on population #’s
      • 500 or fewer = 1 sample/day
      • 501 – 1,000 = 2 samples/day
      • 1,001 – 2,500 = 3 samples/day
      • 2,501 – 3,300 = 4 samples/day
      • 3,301 or greater and all other systems that monitor continuously
        • Must report lowest value each day
entry point chlorine reporting requirements continued
Entry Point Chlorine Reporting RequirementsContinued
  • Entry point chlorine residuals must be at least 0.2 mg/L at all times.
    • Some systems may have a higher entry point chlorine concentration requirement.
      • To meet contact time requirements.
        • Flow Characteristics
        • Turbidity levels
entry point chlorine reporting requirements continued1
Entry Point Chlorine Reporting RequirementsContinued
  • If entry point residual drops below 0.2 mg/L
    • Contact DEC soon as possible - no later than the end of the next business day.
    • Date and duration below 0.2 mg/L must be recorded on page 2 of the operator report (Entry Point Disinfection Performance Criteria).
    • DEC will review if treatment technique violation was generated.
        • If chlorine level is raised above 0.2 mg/L within 4 hours, no violation will be assessed.

Fluoride Reporting Requirements
  • Measured daily at the entry point to the distribution system.
  • Entry point fluoride residual must not exceed 2.0 mg/L.
  • Notify DEC within 24 hours if fluoride residual is equal to or greater than 2.0 mg/L.
fluoride reporting requirements continued
Fluoride Reporting RequirementsContinued
  • On the first day that the fluoride residual is > 2.0 mg/L, a confirmation sample must be collected and sent to a certified laboratory to verify field test results.
  • Public Notice requirements will be based upon certified laboratory sample results.
      • Circumstances may dictate otherwise.
