LITTER IN COLORADO, 1971-1972; AN ANALYSIS OF LITTER ON HIGHWAYS AND PUBLIC RECREATION AREAS

THE ESTIMATED VOLUME OF LITTER ON COLORADO HIGHWAYS IN 1971 WOULD COVER A STANDARD-SIZE FOOTBALL FIELD TO A DEPTH OF 13 FEET. THERE WERE APPROXIMATELY 21 MILLION ITEMS OF LITTER. THIS WAS EQUAL TO 2.349 ITEMS PER MILE OF HIGHWAY, OR 9-1/2 ITEMS OF LITTER FOR EVERY MAN, WOMAN, AND CHILD IN THE STATE. ABOUT 4.2 MILLION ITEMS OF LITTER ARE STREWN ON COLORADO HIGHWAYS DURING EACH SUMMER MONTH (AN AVERAGE OF 471 ITEMS PER MILE EACH MONTH). THIS RATE WAS THE SAME IN 1972 AS IN 1971. THE ONLY INDIVIDUAL LITTER CATEGORIES WHICH SHOWED STATISTICALLY SIGNIFICANT REDUCTION FROM 1971 TO 1972 WERE CANS AND BOTTLES. THE AMOUNT OF LITTER DEPOSITED ON HIGHWAYS INCREASES WITH GREATER TRAFFIC VOLUME, POPULATION OF THE NEAREST TOWN, AND NUMBER OF TRAFFIC LANES. ABOUT 52 PERCENT OF ALL LITTER ITEMS DEPOSITED ON HIGHWAYS CONSIST OF PAPER OR CARDBOARD (AS LARGE AS A CIGARETTE PACKAGE, OR LARGER). CANS COMPRISE NEARLY 26 PERCENT OF ALL LITTER ITEMS DEPOSITED, AND BOTTLES AND JARS COMPRISE ABOUT SIX PERCENT.
