Only the higher am :>unt of the ether represents a significant change from previous samp ling 1 > 2 Additional organic compounds were determined and are reported in the t_w__o a__t_t_a_c__h_e__d T__e_c_h__n_i_c__a 1 Service Reports 3,4. Two of those compounds -- 2,2,2-trichloroethanol and 4-hydroxy-4-mechyl-2-pentanone -- were identi fied at leveLs significantly above the previous findings. No significant chaniges were reflected in the metals or chemical analyses values as given in Tables I and II. DISCUSSION The samples were d sli\ ered to Ponca City on 27 January 1981, by a chartered airplane. Th ose waters were sampled by and shipped in containers provided by the EP \ an d the LCCP. No sample was submitted for total phenols and no bla nks accompanied the samples. The samples were r sceived still adequately packed in ice and below 4 C. On receipt, the samples were stored in a cold room at 4C until analyzed, Extraction of the composited sample for concentration of the nonvolatile organic components was performed within five days, and those extracts were preserved und sr refrigeration until the analyses were performed. Analyses of the ex :ract for organics by GC-MS per Method 625 are reported in this data. Ana lyses for pesticides per Method 608 is in progress and will be report >d separately when available. Analyses of the VOA sample by purge-an i-trap GC-MS was accomplished the same week as received, Subsequent samples from Outfall 201 were received 24 April for deterraination of radioactiv Lty and for volatiles by Method 603. Those data will be reported as soo as available. Determinations of :otal sulfide and sulfite were requested and are included in Table 11, However, the poor stability of those two ions would preclude the Lr presence in the samples when analyzed. Future determinations sho uld be done on site. VVC 000013116 Mike Hayes Page 2 May 5, 1981 REFERENCES 1. Technical Memoirand urn 602-79-801-0 2. Technical Memoirand urn 602-80-839-1 3.
