The secondary effluent fecal coliform sample was taken on December 22d at approximately 8:30 am and was picked up and delivered by laboratory courier. Proper sampling procedures were followed by plant personnel. The result of the analysis showed a value of 24200 MPN per 100 ml. The fecal coliform excursion on December 221 was limited to that sample parameter and day. A phone call was placed to the NCDEQ regional office on December 28h to discuss the results once discovery had been made. After the value from the laboratory was observed, all systems in the treatment facility were inspected. They were found to be operating correctly leading up to and during the time of sample. Leading up to December 221d Fecal Coliform(FC) exceedance,EPI had been further investigating on-going but varied data reported back from our certified laboratory Pace Analytical Services dating back to the week of November 19'. The reason for the investigation was due to a reported FC exceedance of the daily maximum for December 15e EPI submitted to DWR a letter on December I Vh that outlined its investigation into the alleged exceedance. On December 81h after conducting an investigation into the December 1'exceedance,EPI received the FC compliance lab results from Pace. The results indicated the following: Town of Canton, 4.1 MPN/ 100 ml;Upstream, 95 CFU/100ml and the Secondary EfIIuen% 1300 MPN/100ml. EPI questioned this data given the historical data collected from each source coupled with the IXAIIi. 1WveMadc%=1E0HS%SHARMWat9r RlwWkft Walar FllwWEQ NCDWR Page 2 fact that no changes operationally have occurred. When EPI presented this information to Pace, Pace reviewed their internal procedures and EPI was informed that Pace believes that the samples had switched during the evaluation of the data. Pace then sent EPI a revised Laboratory Analysis report which then reflected the values of the Town of Canton(TOC) and the Secondary Effluent to now be switched(4.1 MPN/100m1 for the Secondary Effluent and 1300 MPN/l 00ml for the TOC. Given the now questionable reliability of Pace,EPI felt the need to explore other laboratories that could test for FC. In speaking with Jason Smith from DWR, EPI was presented a list of laboratories in the region who could perform the Colilert 18 method. After analysis of our options, EPI identified only one other lab alternative, Statesville Analytical. As part of the FC study with the TOC and working with FISS environmental,the proposal within the scope of work was if any exceedance were to occur,then have the sample analyzed via Membrane filtration or sent to another lab and have an e.coli speciation performed. To date,EPI has not sent any samples off for e.coli speciation testing but is considering this a probable next step. Back in 2016 when a series of weekly exceedances occurred, EPI did send off at that time samples to the Eden,NC lab for e.coh determination. It was determined at that time to not be of any human or animal origins but rather plant based. This echoed the information EPI obtained from NCASI when informed of the on-going issues. EPI wanted to determine the ability or differences in running the Cohlert 18 versus the membrane filter test for FC. The reason for this analysis was to determine if this was a contributing cause to the varying data that has been received for the multiple sampling conditions. The week of December 18&, EPI began to split the samples to be analyzed into four; two samples going to Pace and two samples going to Statesville Analytical(SA)with each lab being requested to test for FC using both the Colilert 18 and the Membrane Filter methods. The FC results for the week showed that Pace labs had major differences in FC counts given the two methods while the SA lab had very similar results between the two methods. Furthermore,the FC counts from Pace were on average 3-10 times higher than those from SA. Not knowing the aforementioned information, EPI performed the normal compliance test on December 22'and only had the Colilert 18 method performed. On December 27a', EPI received the laboratory analysis report from PACE which indicated that the compliance test performed on December 22"d was 24,200 MPNII00ml. EPI contacted Pace to question the results to determine if the results obtained were switched at the laboratory. At that time, the Pace representative, spearing on behalf of their Microbiologist, indicated that given the recent samples EPI has submitted to run both Colilert 18 and Membrane Filtration,Pace has identified other non-fecal bacteria in large concentrations that in their words was most likely causing interferences in obtaining accurate counts via both test methods. On December 28',EPI contacted the DWR and informed them of the results and EPI's steps to investigate the issue. EPI requested from DWR that a formal conference call be had between the two to discuss the facts and investigational findings. The meeting was scheduled for January 31d. EPI contacted SA and had discussions around the general observations of the EPI samples and if NCDWR Page 3 there was any difficulties in running the samples and to obtain accurate data from those samples. SA responded that they observed non-fecal bacteria present but the samples provided were not such that accurate results could not be obtained. Given the information obtained from the discussions from both labs,the decision was then to have SA perform the analysis. However, the week of December 25a', SA did not have a currier to pick up samples and as such,EPI sent the weekly routine samples again to Pace with the December 291 compliance sample split to run both the Colilert-18 and the Membrane Filter test. The results for the December 291 test was received on January 21 and indicated a wide difference between both test procedures(2910 MPNA00m1 for the Colilert-18 versus 610 MPN/100m1) for membrane filtration. EPI investigated its operations and found no change in its operations. EPI then formulated the sampling scheduled to have SA run both FC tests on the TOC and#4 flume on January 3'd and the same on January 41 but also include the secondary effluent. For the week of January P,the following sampling schedule has been developed: January 9a': Pace—TOC and#4 Flume with both FC test procedures. SA—TOC,Upstream,#4 Flume and Secondary Effluent with both FC test procedures. An additional split sample of the Secondary Effluent will be collected to have a heterotrophic classification test performed. January 10th: SA-TOC and#4 Flume with both FC test procedures. An additional split sample of the#4 Flume will be collected to have a heterotrophic classification test performed. January l lm: Pace—TOC and#4 Flume with both FC test procedures. SA—TOC,Upstream,#4 Flume and Secondary Effluent with both FC test procedures. An additional split sample of the Secondary Effluent will be collected to have a heterotrophic classification test performed. The reason for the additional testing, switching the testing to another certified laboratory and to obtain heterotrophic classifications of the material present in the discharge samples is because EPI believes the current laboratory data acquired from Pace is not accurate nor is it representative of the effectiveness of the treatment abilities conducted at EPI. EPI had a formal conference call with the DWR on January 3'd to discuss the investigative approach and DWR has requested to split samples on January 91 and 11*and have the results tested in their laboratory. DWR also requested to witness the entire preparation, capture, collection and preparation of the samples. EPI requests to the DRW that enforcement discretion be given pending the outcome of the sampling results submitted to the certified lab SA and also the results obtained through DWR's split sampling and internal testing.
