IN CHLORINATED SEWAGE EFFLUENT: COPPER, LEAD, CHLORAMINES, AND 2,4-DICHLOROPHENOL THIS PROJECT WILL INVESTIGATE THE EFFECTIVENESS OF THE

NUTRIENT FILM TECHNIQUE (I.E., DENSE ROOT MASS FROM PLANTS GROWING IN A THIN FILM OF WASTEWATER) IN RE- MOVING FOUR TOXIC SUBSTANCES COMMONLY ENCOUNT- ERED IN COOLING WATERS AND CHLORINATED DOMESTIC SEW- AGE WITH INDUSTRIAL INPUTS. TWO CHLORINATED COMPOUNDS (CHLORAMINES AND DICHLOROPHENOL) AND TWO TRACE HEAVY METALS (COPPER AND LEAD) ADDED TO SECONDARY TREATED SEWAGE EFFLUENT WILL BE EVALUATED ACCORDING TO: (1) THEIR PERCENTAGE REDUCTIONS OVER A TWO-MONTH PERIOD USING THE NUTRIENT FILM TECHNIQUES: (2) THE AMOUNTS TAKEN UP IN THE ROOTS AND AERIAL PORTIONS OF THE SELECTED PLANT PROVIDING THE NUTRIENT FILM; AND (3) THEIR EFFECTS ON THE GROWTH AND SURVIVAL OF THE PLANT PROVIDING THE BUTRIENT FILM.
