Within 4 hours collect triggered GWR source sample from each well that was in operation within week prior to sample collection date. source samples E. coli positive Conduct daily compliance. Tier public notice within 4 hours;. Collect 5 additional source samples within 4 hours ;. Notify wholesale systems 5 additional source samples E. coli positive. Consult with NJDEP. Submit Corrective Action Plan within 0 days Does the system continue to use the same well without 4. Complete Corrective Actions within log treatment of 0 days viruses?

TES If 5 additional samples are not collected within 4 hours the system must proceed to corrective actions Corrective action options include: eliminate source of contamination, provide alternate source of water, and/or installation of 4 log treatment of viruses December05

2 RTCR FLOW CHART FOR SYSTEMS ON QUARTERLY MONITORING Was your routine sample total coliform positive ()? Continue with routine schedule, according to your sample siting plan.

Do you serve >,000 persons community water system? routine sample per month routine sample per quarter 4, 5 TES Seasonal system is defined as a non community system that: is not operated as a public water system on a year round basis and starts up and shuts down at the beginning and end of each operating season, or remains pressurized during an off season but serves less than 5 persons, or depressurizes a portion of the system but continues to serve water to the public. A community system serving <00 service connections that doesn t disinfect is required to collect routine samples per month at biweekly intervals Surface water/gudisw systems that are unfiltered must collect a sample near the first connection each day the turbidity of the source water exceeds NTU 4 Collect routine samples a month following a routine total coliform positive sample result. 5 System may trigger increased routine (i.e. monthly); refer to Increased Monitoring Fact Sheet Population Minimum # required,00,500,50,00,0 4,00 4 4,0 4, ,90 5, ,80 6, ,70 7, ,60 8, ,50,900 0,90 7,00 5 7,0,500 0,50 5, ,00,000 0,00 4, ,00 50, ,00 59, ,00 70, ,00 8, ,00 96, ,00 0, ,00 0, ,00 0, ,00 450, ,00 600, ,00 780, ,00 970, ,00,0,000 00,0,00,50,000 0,50,00,850,000 60,850,00,70,000 90,70,00,00,000 40,00,00,960, ,960,00 or more 480 December05

5 FACTSHEET: Revised Total Coliform Rule(RTCR) WHO DOES THIS FACTSHEET APPLY TO? Repeat Monitoring Requirements ALL PUBLIC WATER SYSTEMS (PWSS) that are required to conduct repeat when a routine sample is POSITIVE FOR TOTAL COLIFORM () BACTERIA. RTCR What to Do? Step Collect after each routine sample Step Conduct required actions after collecting repeat samples STEP : COLLECT REPEAT SAMPLES FOR EACH ROUTINE SAMPLE YOU MUST COLLECT A SET OF REPEAT SAMPLES AFTER EACH ROUTINE SAMPLE. You must continue to collect a set of until either TC is not detected in one complete set of or you trigger an assessment. Repeat Sampling Locations You must collect at least at the locations described in your sample siting plan: () repeat sample at the original routine location, () repeat sample within five service connections upstream, and () repeat sample within five service connections downstream of the sample. You may choose alternative repeat sampling locations on a situational basis contact your state for more information. FOR ASSISTANCE, PLEASE CONTACT: NJ DEP: BUREAU OF SAFE DRINKING WATER PHONE: Site B = repeat upstream Site A = repeat Original routine location that tested Site C = repeat downstream ATTENTION! COLLECT ALL REPEAT SAMPLES. If you do not collect and analyze at least (for each routine ) you will have to perform a Level or Level assessment. See the RTCR Factsheet: Level Level Assessments and Corrective Actions. REMINDER: ANALYZE ALL REPEAT SAMPLES FOR E. COLI.* watersupply@dep.nj.gov Frequency Timing Collect all WITHIN 4 HOURS** AFTER RECEIVING TIFICATION FROM THE STATE CERTIFIED LAB OF THE SAMPLE RESULT. The must be taken on the same day. TES *CALL THE STATE on the same day you learned of the E. (EC+) result, or by the end of the next business day if the result came in after business hours [Bureau of Safe Drinking Water or NJDEP hotline 877 WARN DEP] and tell them you received an EC+ result. **Contact your state for an approved extension if logistical problems prevent collection within 4 hours.

6 RTCR STEP : CONDUCT ACTIONS REQUIRED AS ARESULT OF YOUR REPEAT SAMPLING = Total coliform positive or present; TC- =Total coliform negative or absent EC+ = E. or present; EC- = E. coli negative or absent; EC? = E. coli not analyzed You must COMPLETE AN ASSESSMENT SUBMIT THE FORM TO THE STATE WITHIN 0 DAYS after you learned your PWS has triggered an assessment. See the RTCR Factsheet: Level Level Assessments and Corrective Actions. If Routine Sample Is: And Any Repeat Sample Is: Action: What do your sample results mean? Violation The presence of total coliform bacteria in both your original routine sample and in your follow up repeat sample suggests there could be a problem and your water may not be safe to use.. CONDUCT A LEVEL OR LEVEL ASSESSMENT. Contact the state for help determining which type of assessment is required. No MCL violation EC? The presence of total coliform bacteria in both your original routine sample and in your follow up repeat sample suggests there could be a problem and because E. coli was not tested, it is unknown whether or not the water is safe to use.. TIFY THE STATE within 4 hours of receiving sample results. CONDUCT A LEVEL ASSESSMENT.. ISSUE A PUBLIC TICE (PN). violation EC+ The presence of E. coli bacteria in your water is an indicator of fecal contamination and your water may not be safe to use..

TIFY THE STATE within 4 hours of receiving sample results. CONDUCT A LEVEL ASSESSMENT.. ISSUE A PUBLIC TICE (PN). violation TE Systems collecting 40 or more samples per month trigger an assessment only if more than 5% of samples collected are total coliform positive. You are required to provide Tier public notice within 4 hours in response to an violation. December 05

7 FACTSHEET: Revised Total Coliform Rule(RTCR) Increased Monitoring Requirements WHO DOES THIS FACTSHEET APPLY TO?

A system on quarterly that experiences any of the events identified below must begin monthly the month following the event. System triggers a Level assessment or two Level assessments in a rolling month period. System incurs an violation System incurs a coliform treatment technique violation System has two violations under the RT CR in a rolling month period System has one violation under the RTCR and triggers one Level assessment in a rolling month period Existing water quality data. TES APPROVED PARTIES INCLUDE: ATTENTION! PROTOCOL FOR INCREASED MONITORING SHOULD BE OUTLINED WITHIN YOUR WRITTEN TOTAL COLIFORM SAMPLE SITING PLAN CAN MY SYSTEM RETURN TO QUARTERLY MONITORING? A system on increased may return to quarterly if it meets all of the following criteria: A Sanitary Survey or Site Visit was completed by the State /Administrative Authority or a voluntary Level assessment was conducted by an approved party within the last months and no sanitary defects were identified and the water source was determined to be protected; System has a clean compliance history for a minimum of consecutive months THE STATE A COUNTY ENVIRONMENTAL HEALTH ACT CERTIFIED AGENCY LICENSED OPERATOR OF A CLASS COMPARABLE OR HIGHER TO THAT WHICH IS REQUIRED OR IF SUCH REQUIREMENT EXISTS (I.E.
