Introduction 3

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. 4

Introduction Continued 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 5

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. 15

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 16

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. 17

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 21

Entry Point Chlorine Reporting Requirements Continued 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 22

Entry Point Chlorine Reporting Requirements Continued 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. 23

Filter Reporting Requirements Did you filter & produce water during the day? Check “Yes” or “No” 27

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. 31

Fluoride Reporting Requirements Continued 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. 32

Presentation Outline Introduction Elements of an Operator Report & Reporting Requirements Common Reporting Errors and Issues Summary 53

Common Reporting Errors and Issues Distribution chlorine residuals Not collected at the same time and place as total coliform sample. Not recorded on operator report. Readings written on total coliform sample paper work may not always be reported to us by the lab. Missed same time and place chlorine residual results in two violations Distribution system residual requirement Maximum Residual Disinfectant Residual (MRDL) requirement 54

Common Reporting Errors and Issues Late submittals Reports due to DEC by the 10 th of the following month. Late reporting violation Missing operator signature & date Required by 18 AAC Late reporting violation if amended report not received by 10 th. 55

Common Reporting Errors and Issues Not submitting or filling out all the required pages Not notifying DEC when required Turbidity exceedances Low entry point chlorine levels Month & Year of report not recorded 56

Common Reporting Errors and Issues Illegible handwriting Decimal point errors 57

Summary Operator reports are an important and useful tool to keep track of your system performance. Turbidity readings CFE’s for all system types. IFE verification for Conventional & Direct systems. Chlorine readings Entry point Distribution Fluoride readings Operational issues or anomalies Satisfies regulatory reporting requirements 59
