WATER WORKS DIGEST - INSECTICIDE RESIDUES

THE TWO IMPORTANT SOURCES OF POLLUTION ARE RUNOFF FROM AGRICULTURAL LAND AND DISCHARGE OF WASTES EITHER FROM INDUSTRIES THAT MANUFACTURE PESTICIDES OR FROM THOSE THAT MAKE USE OF THEM IN THEIR PROCESS. AERIAL SPRAYING CONTRIBUTES MORE TO THE STEADY SOURCE OF PESTICIDES IN RIVERS IN THE U. S. THAN AGRICULTURAL RUNOFF. THE MAIN HAZARDS OF INSECTICIDE RESIDUES IN WATER ARE: LARGE NUMBERS OF AQUATIC INVERTEBRATES AND FISH MAY BE KILLED, AND THE RESIDUES MAY BE TAKEN UP INTO THE TISSUES OF THESE ORGANISMS. IT IS NECESSARY TO EXAMINE WHETHER PESTICIDES CAN BE REMOVED BY WATER TREATMENT PROCESSED, ONCE WATER GETS CONTAMINATED WITH THEM. IT WAS SHOWN THAT, AT RELATIVELY LARGE AND IMPRACTICAL CONCENTRATIONS, OZONE DID REDUCE CHLORINATED HYDROCARBONS SOMEWHAT BUT, AGAIN, BYPRODUCTS FORMED AND THEIR TOXICITY IS NOT KNOWN. THE ADDITION OF ACTIVATED CARBON TO THE TREATMENT SYSTEM WAS FOUND TO DECREASE THE AMOUNTS OF INSECTICIDES IN WATER, BUT THE AMOUNTS OF CARBON REQUIRED WERE LARGE. /PW/
