Vandals in the early hours Sunday pushed over 11 portable toilets that had been set up in the parking lot of West Marin School for a lunch stop on the Waves to Wine Bike Tour. The tour, which passed through Point Reyes Station Saturday, was a fundraiser for the National Multiple Sclerosis Society. Each of the toilet stalls holds 30 gallons of sewage and chemicals.

West Marin School Principal Anne Harris (right) and firefighter Joe Morena on Sunday worked out cleanup plans with Jennifer Snow of Marin County Environmental Health Services and crew from the portable-toilet company. The group decided against hosing off the sloped parking lot because that would send contaminated water into the school’s storm drain and potentially into Papermill Creek. Instead, the group decided to wet vacuum the area and disinfect it with bleach.
