Some elements contained in aq. and non-aq. drilling lips. were detd. by std. elution test. Chem. compns. of eluates as well as their electrolytic cond. were detd. by at. absorption spectrometry and conductometry, resp. The eluates derived from aq. waste contained much more Na, K, Ca, Cl ions and revealed better electrolytic cond. than the non-aq. eluates. A preliminary desalination of the wastes was recommended.
