Iowa – Grant – Lafayette County Clean Sweep Event

Improperly handled chemicals can pollute ground and surface water and pose health risks for you and your family.  Clean Sweep allows you a one-time opportunity to safely dispose of these chemicals.  All Grant, Iowa, and Lafayette County residents, farmers, and agri-businesses can participate in this program.  Pre-registration is required.  You may register online at or by calling Tom Harman at the Extension Iowa County office at (608) 930-9850.

The dates/times/locations for the events are:

  • Friday, September 23rd from 2-6pm in Lancaster (Grant County Fairgrounds)
  • Saturday, September 24th from 8am-noon in Lancaster (Grant County Fairgrounds)
  • Friday, September 30th from 2-6pm in Dodgeville (Iowa County Hwy Dept, 109 Leffler Street)
  • Saturday, October 1st from 8am-noon in Darlington (Lafayette County Hwy Dept, 12016 Hill Street)

At the Clean Sweep site, a licensed hazardous waste disposal firm will collect the chemicals with assistance from local volunteers.  Disposal is simple and convenient – you will not need to leave your vehicle!

Pre-registration is required.  You will need to estimate the amount and list the type(s) of chemicals you plan to dispose.  Registrants with 100lbs or more of total chemicals will be contacted to determine if a fee is required.  Non-farm commercial enterprises must contact the waste collection company directly (Veolia North America: or 262-253-3504).  Once arrangements have been made, you must call 608-930-9850 to register.

Here are some safety guidelines when preparing to transport chemicals for disposal:

  • Visually inspect containers before lifting.  Secure lids, caps, and covers before moving.
  • Leave materials in their original containers.  DO NOT mix materials!
  • Leave all labels in place, even if worn or torn.  If labels are missing, please list contents with a permanent marker.
  • Place the containers in a plastic or garbage bag lined cardboard box for easy hauling.
  • Use the trunk of your vehicle or truck bed.
