EXHIBIT 16 WATER PCB-SD0000069710 Monsanto Monpjnto Company 00 N. Lindtprgn loulavard St. Louia. Miaaouri 83188 Ptiont: OU) 884-1000 August 6, 1970 ,OMwe CMOnfi*LS 0^ MCS 1016 Since environments 1 probes for PCB's reflect the presence of the aore highly chlorinated biphenyl compounds, Monsanto prepared an expcriaental amount of Aroelor 1242 from which a significant portion of the aore highly chlorinated eoopounds have been reaoved. This experimental material la called MCS 1016. The amount you requested for your capacitor studies Is enroute to your attention, delivered at no charge. * Attached is our comprehensive analysis, Indicating the properties typical for MCS 1016. The enclosed list of Aroelor 1242 properties la for your convenience In comparing these two materials. The comparison reflects what one would expect after removing a signifi cant amount of the more highly chlorinated biphenyl compounds from Aroelor 1242. The excellent resistivity and power factor values given for MCS 1016 do not reflect a decimal point In the wrong place. However, It is amt to be misconstrued that the electrical values of MCS 1016 are Intrinsically superior to those obtainable with Aroelor 1242. Both auterlals attain these excellent electrical values when highly refined by adsorbents.. f WATER PCB-SD0000069711 Page 2 August 6, 1970 Ths electrical values given for MCS 1016 art not based on a ample from the storage tank. Instead, they are based on individual analysis of about ten sastples removed froa ths dnas in which the aaterlal was pack aged. To account for the good results, we wish to indicate that handling, saapllng, and analytical work on this experimental aaterlal wae super vised by Dr. Ralph Hunch in our Research Laboratories. He employed his recently-developed procedure whleh eneoapasses special care required for the proper anelysla of the power factor and resistivity of highly refined ArocloT. In light of thla careful handling and testing at our end, and the vide simultaneous distribution of this aaterlal to the capacitor suikers, we have good opportunity for a "round-robin" teat of power factor and re sistivity. We will appreciate it If you will saaple your shipaent prompt ly and give us your readings of power factor and resistivity. In any event, the prime purpose of sending the MCS 1016 Is to give you an opportunity to run capacitor life tests. Looking ahead. It appears likely . that we will need to convert to the MCS 1016 type aaterlal aa a step In the direction of helping on the PCB pollution problea. Thank you for your assistance.
