The principle objectives of this investigation were the recovery of organic micropollutants from subsurface and surface Missouri waters; the characterization and identification of these substances; the evaluation of their toxic effects, both acute and long‐term; and, the development of methods for their destruction or removal. The carbon adsorption method of recovering trace organics from water was used. Because of the higher concentration of organics in the spring water, large quantities of extracts were obtained and permitted extensive toxicity studies. The acute and long‐term toxic effects of the surface and subsurface organics were quite different, as were their effects upon respiratory enzyme systems. The batch‐type long‐term bioassay, necessary because of the limited quantity of organics available, provided a workable procedure for the evaluation of the cumulative long‐term effects of the trace organics. Tissue studies and visual observation of dissected exposed fish provided an insight on the mode of action of the toxicants.
