KANSAS VINYL CHLORIDE MONOMER CONTAMINATION an Executive Summary of Work to Date by Dave Eckstein, Deputy Executive Director Uni-Bell PVC Pipe Association .Tune. 1992 Kansas Department of Health and Environment (KDHE) detects Vinyl Chloride Monomer (VCM) in water in Doniphan County Rural Water District #5 (< 1 ppb to 8.9 ppb) while testing for carbon tetrachloride. No other VOC's were found leading suspicion to PVC pipe. KDHE samples "6 or 7" other rural districts. "A couple" had 1 sample out of three over 1 ppb. Resampling found no detects in all cases. Julv. 1992 KDHE provides public notice of vinyl chloride contamination to Doniphan #5's customers advising the use of an alternate source of drinking water., ~ /Ja /y)u<? C7-?o September. 1992 KDHE resampled Doniphan #5 and found VCM in water from 2.9 to 7.4 ppb. Pipe samples were obtained sections removed for repair. Three pipe samples were filled with water containing 1 mg./l free chlorine. Ten day results showed VCM at 11.1, 7.3 and 7.2 ppb. Samples were filled with distilled water and 10 day residence resulted in VCM at 5 to 15 ppb. Att> Qte ^ / 3o (? *5 - CTL032801 December. 1992 KDHE contacts Uni-Bell PVC Pipe Association of suspicion of 20+ year old PVC Pipe with VCM contamination problem. Uni-Bell verifies with Vinyl Institute (VI) scientific community membership the opinion that the pipe could not be the VCM source. UniBell recommends National Sanitation Foundation (NSF) as a proper test facility for VCM in pipe and water sampling. Marb-220S33 EPA Region VII contacts Uni-Bell of NSF findings of extraordinary VCM levels (270330 ppm) found in PVC Pipe samples from Doniphan #5 and requests assistance in remediation techniques. /* 77 - /*> />/> /V __ MS?

Reviewed testing history including above as well as verification that further testing consistently showed no detects in all post-VCM certified pipes. Doniphan #5 pipe was manufactured by CertainTeed . Corp. Uni-Bell was requested to assist in development of remediation alternatives and 1 notification of CertainTeed Corp. i Uni-Bell notified CertainTeed and VI of conference call. Uni-Bell and VI identified a project team of Dr. Ron McCreedy, Dow Chemical, Don Goodman, Occidental, Dr. Byeong Jo, CertainTeed, Bob Burnett, Vinyl Institute and Dave Eckstein, Uni-Bell. ApriL22,J293 Conference call with VI Technical Committee members and Uni-Bell determines that NSF should be contracted to serve as lead agency to coordinate governmental agencies and perform testing to determine the actual source of VCM. CTL032802 Mav 19.1993 Meeting in Ann Arbor with NSF and members of the Uni-Bell/VI project team to define NSF contractual involvement. Consensus results in a not-to-exceed $25,000 project to include record review, water and pipe testing, remediation recommendations and governmental coordination. Industry names Dave Eckstein of Uni-Bell as project lead. Mav 28,1993 NSF names Dr. Ken Smith, Vice President of Conformity as project lead. July 7.1993 Presentation of test results: 1) Data satisfies scientific representatives of both NSF and Industry that the 23 year old pipe is the source of the VCM in the water. 2) It is further agreed that a check with the currently accepted migration model (Bellem et al 1987) would predict this behavior given known resin RVCM levels of 2000+ ppm pre-1974. NSF agrees to prepare an interim report which will include sampling protocol and test results. Further the report will preview the final report which will include a presentation of remediation alternatives and their relative merits. July 7-9,1993 Uni-Bell Board of Directors telephoned of meeting findings. Uni-Bell Board Chairman commissions a special Board Sub-Committee to consist of all PVC potable water pipe producers. Jim Rash, of PW Pipe, agrees to serve as Sub-Committee Chairman. CTL032803 July 13.1933 VI Executive Board conducts teleconference to update on findings. Executive Board agrees to a July 27 meeting under the VI, Issues Management Committee to include UniBell and VI representatives to include technical input, business analyst, legal and public relations experts in Washington, DC to develop a proposed plan of action. July 14,1993 Industry and NSF project leads agree that the data has changed the original project. Priority now includes coordination with governmental agencies to preview reactions and needs. NSF agrees to organize a meeting of NSF/Industry and EPA. NSF also agrees to hold interim report until such meetings occur. VI Technical Committee Chair informed VI legal counsel and project team leader of concerns within TSCA, 8(e) requirements. Counsel for both VI and Uni-Bell will research and render opinion. Industry Team Leader contacts KDHE for VCM testing details. KDHE reports approximately 200 rural water districts in Kansas. They identified 20 of the most suspect systems (oldest pipes) and took three or four samples from points farthest from the water entry point to obtain longest residence time. These twenty locations included retest of Doniphan #5. One other system, Franklin County Rural Water District #4 also tested at a VCM concern level. Some other tests were erratic.
