Officials test powder after incident
There is no hazard to the public, county highway superintendent Hal Mayer said, and the county worker is fine. The worker was treated and released at Edgerton Hospital.
The worker noticed the substance, which had not washed away after a rainfall earlier in the day. The worker kicked the substance and later felt light-headed, Janesville Fire Capt. Jim Dennis said.
The Janesville Fire Department hazmat team assisted Edgerton officials, and they contained the one-quarter to one-half cup of powder and cleaned the area, Dennis said.
