have a high frequency of occurrence, and under certain conditions
can be anticipated. Protection is best provided by avoiding potential flood areas, which is
not always practical. Prevention is possible under most conditions, but often at substan-
tial costs.
Health hazards
related to geologic conditions include asbestos, silica and radon, and the
various minerals found in groundwater such as arsenic and mercury. Recently, mold has
been added to the list of health hazards. Discussion of environmental concerns related to
health from contaminants are beyond the scope of this topic.
