We can't just transfer it to you because they need your billing information, so you'll have to call. Our account is being cancelled on December 261", 2018. For the Johnny's Sav-A-Sum site Incident #15622 we have been supplying bottled water to: 3910 U.S. Highway 601 South Concord, NC 28025 (Annie Smith) 3878 U.S. Highway 601 Concord, NC 29025 (Winnie Ballard) It is provided by: Crystal Springs 1-800-492-8377 Account No. 643808414610736 Below is a brief summary of the lead detected in water supply wells which is why bottled water is supplied to the owner of WSW-3910 and WSW-3878: • The concentration of lead has historically and sporadically exceeded the 2L Standards in water supply wells WSW-2144, WSW-3878, WSW-3910, and WSW-4036. Lead was not detected in any of the monitoring or recovery wells during the September 2018 sampling event. Lead was detected in WSW- 3910 during this sampling event but did not exceed the 2L Standards. Due to the presence of an MTBE plume on site and no lead plume on site, the data indicates that the site source is unleaded gasoline. Therefore, the presence of lead in the sampled water supply wells is unlikely to have been contributed from the site. However as requested by the NCDEQ, we have been supplying bottled water to the above for approximately 4 years. The last delivery was December 5, 2018. Further, here is a brief summary of a recent detection of methyl tertiary butyl ether in a nearby supply well: • Since the February 2018 shutdown of the remedial system per instructions from the NCDEQ, the levels of petroleum contamination increased in fourteen of the monitored wells. One of the wells is an offsite water supply/drinking well which has never had petroleum contamination before (WSW-2144). In Shield Engineering, Inc.'s May 18, 2018 Monitoring Report, the first recommendation was to monitor for offsite migration of contaminants since the system had been shut down and there is no longer hydraulic control of the contaminant plume(s). Based on the above, we recommended in our October, 2018 Monitoring Report to restart the remediation system to regain hydraulic control of the i contaminant plume(s) and to reduce the levels of contamination. This will now be a decision to be decided by the State Lead Program since our client, Techno, LLC has been dissolved. The source of the MTBE in WSW-2144 is uncertain. Because of this uncertainty, and since the levels of MTBE are below the 2L Standards, Shield Engineering, Inc and Techno, LLC for Holding Brothers, Inc. deferred to the NCDEQ in our October, 2018 Monitoring Report to advise the owner of WSW- 2144 of the presence of MTBE in their water supply/drinking water well. Bottled water may need to be supplied to this residence. These too will have to be decisions for the State Lead Program since our client, Techno, LLC has been dissolved. Thank you, David David A.
