Lead in the Environment
How has the Golden Gate Bridge
Affected the Horseshoe Bay Recreation Area?
Horseshoe Bay at East Fort Baker is a popular place for
fishing or crabbing and a favorite launch and picnic spot for many
boaters. The goal of this experiment is to determine if the lead
content of soils and sediments near Horseshoe Bay in East Fort Baker
is high enough to pose a hazard to people or marine life in the area.
Samples were taken by the UC Berkeley Environmental Chemistry lab
sections during the week of February 3.

Data Entry Grade:
You will receive all of these points if you enter your
data on time into the computer. If you have to be
reminded about data entry, some or all of these points will
