i � ATTACHMENT 1 <br /> Eaj <br /> d <br /> Interoffice Memo <br /> TO: Noel Schomburg CC: Duane Grady <br /> Lee Talbott <br /> John Bingham <br /> FROM: Charles Clarke <br /> DATE : April 12 , 1988 <br /> SUBJECT : Water in Beaver Lagoon <br /> Attached are two copies of an analysis done on the water <br /> and sediment of the holding pond at Beaver Chemical. The <br /> first one was done on heavy metals by Environmental <br /> Services of Chem Bio Corporation . Thallium was added to <br /> the list because of the metal being found on the California <br /> Land Ban`:;sr Its limit is 130 m per litre. As <br /> B P you can see , <br /> this along with the other metals were all below the limits <br /> dictated either by U. S . EPA or the State of California . <br /> The second report was a sample of the water run at Avganic <br /> Industries . This did show some volatile organics in the <br /> waste water, though in talking with John Bingham, we are not <br /> sure of the source of these particular organics . The <br /> analysis did not show any indication of chlorinated solvents , <br /> which would be much more difficult to treat , if necessary . <br /> A test for PCB ' s was also done , and found negative as <br /> indicated. <br /> Obviously , the heavy metal sampli_ indicates no problem , <br /> nor does the one for PCB ' -- . The organic solvents indicates <br /> some presence though not at a tremendously hi=h level . It <br /> is necessary co continue vigilance on keeling such products <br /> - from beim disc'rarge3 into the pont . The sampling for this <br /> was developed for the waste water at Avganic , which has a <br /> sijnificantly .^lg:_._ level Or--ania .ran those detectei here . <br /> Though these numbers --a;: not be Susolute , it does show t`_.t <br /> there is sore '7OC ' s * here . 4-ter r <br /> =viewi ^- - he above <br /> information , if you =ave any fur- _' - �lle5: _on3 , _1eaze feel <br /> free to cent�_ ct -e . <br /> Charles <br /> cs <br /> Attachment <br />
