]anuary 6, 1993 ^ <br /> Metals Soil Data Validation Review <br /> Page 2 <br /> 2. Hlanks <br /> A�seoic w�s detected in the da:oohmination blank(DB�B-12492)at a concentretion of 0.011 mg/I. T6e <br /> �rswic conc�tration in ihe sample �ssocieta! with 16e docontamination blank was greater than 5 times the ' <br /> coocmtradon detected iu tha dacoomn!ination blenk, Iherofom qualificadon of the sample datx was not necessary. <br /> Target metais were nat datected in t6a method blrnlcs. <br /> 3. Dupliate Sample Analysis <br /> TLe differmce in mercury results ia the duptiate sample analysis�ssociated with DB-SB-12492 was 0.5 <br /> ug/!,which e�ccaeds the QC Woits of+/-CRDL(0.2 ugA)for sample values less than 5 times�he CRDL. Mercury <br /> wae not detected ia DBSH-12492;t6e detxNon limits wero fl�ggad UJ. In the duplicata sample aoalysis�ssociated <br /> with dl the�bove soil s�mpl�,the rolative per«at difkiraoe(RPD)for rinc(85.13%)excoeded the 3596 QC limit <br /> for s�mple rosilts groater th�n 5 times the CRDL. Zinc was detected in dl of the soil samples, and the results were <br /> Flagged J. <br /> 4. Matri�c Spike Sample Analysis <br /> TLe following matrix spike recoveries (%R)wero autside the QC limits of 75-125`�: <br /> ■t ' � �8 . <br /> Water Mercury 30.0 <br /> Soil Arswic Nat calculable <br /> Soil Lead 44.0 <br /> Soil Zinc Not calculable ° <br /> Metcury wes not detacted in the decontaminaUon blank (DB-SB-12492) sssociated with the water matriz spike <br /> sample analysis;the detection limits waro flagged U7. The arsenic, lead,and anc results listed abova ere associated <br /> with dl soil samples. Sample lead results were Flagged J when greater Ihan t6e iashument detection limit(►DL) <br /> and UJ whm less ihan t4e IDL. 'Ibe 96R for arsenic and rinc ware oot calculeble due to the spiked ssmple results <br /> being less than the origioal sampla results. Zinc was detxted in dl of the sail samples and t6e results wero flagged <br /> J. Atseaic wu dUxtad in all semples ezcept TP-2-2;positive arsenic results were Flagged J and the arsenic results <br /> for TP-2-2 were rejected (R). <br /> i 4 <br /> I vysw.Mer � <br /> � <br /> ,_. <br /> I <br /> E, <br /> I <br />
