This month’s theme is Green Buildings, and will include the following highlights:

A Cottage Grove teenager has died in a dirt bike crash.

The incident happened at about 5:15 p.m. Wednesday in the 4500 block of Myer Road, near County Road BB and County Highway N.

Cottage Grove Police Chief Chris Hughes said the 15-year-old boy was trying a trick maneuver on the dirt bike, which caused the bike to go airborne. He said the teen lost control of the bike and hit a tree.

The teen was wearing a helmet and protective gear, but he died as Med Flight was taking him to a local hospital.

Grief counselors spent Thursday at Monona Grove High School, where the teen attended classes.

Soil contamination next to Monona Grove High School is causing vapors to seep inside the building, but state Department of Natural Resources officials said that the vapors pose no hazard to students or staff.

Monona Grove Superintendent Craig Gerlach informed parents about the contamination in a letter written on Sunday. The vapors of tetrachloroethylene, also known as PCE, originated at Klinke Cleaners next to the school.

"Absolutely it's a concern of everyone, especially those who have children," Gerlach said. "The building's safe. If the building was not safe, we would not send children and staff into that building."

After meeting with the school, DNR officials tested the air inside the building. Investigators told Gerlach on Saturday that the results showed that vapors beneath the school have seeped inside the building, but the levels measured don't pose a threat to humans.
