MILL VALLEY DUMP
120 Camino Alto, Marin County, California
The Biggio Brothers operated a private dump (landfill) from the 1920s until the 1950s with few government regulations on waste disposal. The city of Mill Valley acquired the property after the dump closed.
Chronology:
1920s – 1950s Mill Valley Dump
No record found of cleanup of the Mill Valley Dump.
1972 Mill Valley Middle School opens on top of a portion of the closed dump
1989 Heavy metals and arsenic are found in soil samples taken at the school
1991 Benzene, toluene, ethyl benzene, xylenes, antimony, arsenic and lead are in soil samples taken at the community center to be built next to Mill Valley Middle School. Plans for the center include softball and soccer fields.
1995 Methyl ethyl ketone, chlorobenzene and acetone are found in groundwater. Gases within the dump are measured at explosive concentrations.
1996 Pipes are installed beneath the newly built gymnasium addition at the Mill Valley Middle School to collect gases from the dump. The gases will be piped
to the roof level and released into the air.
1998 Methane gas is measured at explosive concentrations in soil samples taken from an area planned for the community center.
1998 Sports fields open on a portion of the community center site. Five newly installed modular classrooms at Mill Valley Middle School are equipped with alarms set to go off if gases from the dump reach explosive concentrations within the classrooms
1998 The Mill Valley Community Center opens. Pipes are installed beneath the buildings to collect gases from the landfill. Chemical gases are piped to the roof and released into the air. Alarms are set to go off if gases from the dump reach explosive concentrations within the buildings.

We are looking to move to Mill Valley and start a family there. How come there are no responses to this question at all?

Yes, Mill Valley Middle School and the adjacent recreation center were built on a former municipal landfill.

I'm interested in this as well. It surprises me that so many people would be ok with their children spending so much time in a toxic zone. It also surprises me that no one appears to have answered your question. Are people just unaware of this hazard or unconcerned? We're thinking of moving to Mill Valley, but if this is true, that whole zone is off-limits in our search

There has been yet another gas leak at the school. This affluent community certainly has enough money to relocate the students and faculty to a safer facility. The enormous landfill beneath Mill Valley Middle School and adjacent community center contains cancer-causing chemicals and highly flammable, highly explosive gases. Wake up and smell the toxins Marin County!
