LEAD INDUSTRIES ASSOCIATION CAST !* ST**T NKW VOM IT, N.V. 4 k Brief History of the bed uu Ptorr - po t abl e 'ora nxx axnarmsr 19W - 1957 Early la 19li9, an opinion rendered by a scientist of th 0. 9, Foblie Beelth Service, advising against the use of lead palnta la coating tho interior* of potato!* water tanka, lad th* Arwy 3-gineers to prohibit tueh oaa of rod load point* la Ir^ laatollatleno. Thia obviously eliminated the Typo XT rad load phenolic roralob point, than relatively now and tha atandard Federal Spoclfloatloo, aa wall aa tto* Typo X rad load Unload oil paint, from all such use by tha iny> Inquiry by tha load Industries laaociatlon brought oat tha faot that alrttt* ally all potabla water tanka In tha 0.3,1. had baaa Interiorly eoatad with rod load palnta, mainly tha Type I, for a period of some fifty yeara, and vith no know ad verse affect on tha public health, Tha ittuition thua praaentad was placed before tha tight aaatoera of tha Ccamittee on Lead Msoning of tha American Public Beelth laaociatlon, all recopilied aothoritlaa on thia subject, and all of tha* agreed that ary uch prohibition of tha uae of rad laad paint*, without supporting aciantifle iaraatigation, was quite without Justification* Saapita till* evidence and opinion, tha aclantiat abovo rafarrad to flatly re ffused to aodlfy tha adraraa opinion which ha had rendered, or, initially, to interact hiaaelf in any tuch investigation a* tha aaatoara of tha l.P.H.1. comittaa dawad al ianil il to any nodlticatloa of the existing standard* faced with thia attitude, the laad Znduatriaa laaociatlon undertook to cupport an investigation and arranged with Sr. H. B. Elkina, Chief of laboratory of the Division of Occupational Hygiene of the Ilaaaacbuaitte Department of labor and Industriaa and one of tha country'a leading (denticle in thia field, to conduct it. Be came the Type IT paint waa tha eole point at laiue, and aInca field, rather than laborstory tarta, oould fumlah tha only concluaive data, auppllaa of that paint war* furnlahad for the interior coating of two potabla water tanka at Uieeacbueettc atate institution* and teats of the Influent and affluent watera of then tanka have bew conducted froa the tin* of painting to tha present, over periods of serwn and fire yaara, raspectlraly, Mora United atudiea have been aaaa of tha water* of fir* other tanka, two in lfcesachueetta, coated with a synthetic baaa, laad chromate plgaant paint, and thraa in lew Jersey, coated with the Type IT paint, Te tha extant found practicable, it la intended to continue Sr, Elkins * study for tha life of tha palnta* following a report of Dr, Elkina* finding* in hie firat sixteen testa, tha Any ftvgtnr* withdraw in 1951 their prohibition relative to the Typo IT paint* That thia reversal was aaply Justified la shown by the results of tha 81 asapling* (62 tank or effluent, 17 influent, ! other*) recorded in Sr* Elkins* interim report dated October 21, 1957, from which ha concluded that tha possibility of laad beiard from this paint would appear to bo so rwote as to preoludo any need for ssrloue consideration.* It should here be noted that Ituaachusatts waters have been found t* be more aggressive to laad than era those of moat other tf*3* areas* V.

Elkina' field teats, and apparently with the purpose of producing vindication of hie adverse opinion, the Public Health Berrios scientist initiated * aarlea of laboratory baakar Ulti, subjecting the Type I and Typo 17 points, as wU as vinyl base rod lead paint end rod lood la powdered fora, to laaereton In wstors of varying pH, with additions of various cheatsala. Again there was Initial refusal to include ary field sort, although eeasurinacte of lead la the effluent waters froa several nonpotable atorage tanks were ultimately node. The eain point brought out by the unpublished report of this investigation woe that the eolubllity of the Type I paint is considerably greatar, under laboratory conditions, than that of tha two other painta teated. Because (1) theaa were laborstory banker testa only, cot even slaulatlng field conditions, (2) the A.tf.WJL. rv qulroeent that the Type I paint be oodified by addition of 2 lbs. per gallon of Ay litharge was apparently Ignored, (3) the field tests ware on tanks used for deed storage of water for aprinkler and sirilar purpose#, rather than on potable water tanks, (li) there was little investigation of the nature or oonditlon of the paints In theaa tanka, and (5) nothing appears to have been know of the lead content of the waters as receivad into that# containers, the findings of this report cannot be cone aidered to have proved anything with regard to the questions of the suitability of tha Type I and Type 17 painta for the uses at issue. It hid been our understanding, under an agriwant, with the officer then la charge of the agency of tha Public Health Service concerned, that further tnnal iki tlon of these questions would be allowed to await eoopletion of the work by Or. Elkins, at 4>ich ties his report and that of the U.S.P.H.3. study would bo pdblished siaultaneously or In combination. Quito recently, however, apparently as the 0 result of cotxaere lolly activated activities of a paint aalaanan, this use of rod load paints has again been called into question, Stetoaents of dubious validity have been ado and, in an effort to enable cornea tenet to prevail, a conference was held la Pittsburgh on October 30th last, at which Ur. tU E.

It was agreed at this conference that an ad boo eonaittoe of unbiased and qualified experts would be asked to consider the Klklna sod U.S.P.H.3. reports and to wake reoovMndationa as to such further investigation as nay be needed to settle the questions of the suitability of the Type I and type 17 red lead paints for interior coating of potable water tanks, Ur. Jackson and Xr. Keane offered to suboit their slews on this setter. This they have dons, and Dr. Elkins has in turn coaaented ea their views, la this la written, It appear# that the ed hoe coonlttee will be cw* posed of Dr. R, A.
