Don't Trash Arizona Reports Maricopa's Top 10 Litter Hot Spots

Arizona Department of Transportation and the Maricopa Association of Governments announced the "top 10 litter hotspots" in the Valley based upon bags per mile of litter collected between March 2006 and December 2006. [Note: bags per mile is a difficult measurement to base definitive conclusions on.]

Number one spot for litter in Maricopa County: "ADOT crews collected about 7,610 pounds of trash per mile on a five-mile stretch of Interstate 10 between Arizona 51 and 40th Street."

The following was copied from the the Don't Trash AZ website.

   "Each month the Arizona Department of Transportation (ADOT), 
    removes more than 4,000 bags of trash from the freeway system 
    in Maricopa County alone. In one year, ADOT spends an average 
    of $2.3 million and between 65,000 and 70,000 labor hours removing 
    litter from its 6,152 miles of freeways throughout the state."
