. IILC.2. a Evaluatio n o f Possibl e Surfac e Wate r Exposur e Pathway s Summary: Surface water contamination at the State Marine Site presents no apparent public health hazard because it is

unlikely that people would be exposed to contaminants at levels that would be of health concern since: 1)

the probability of ingesting surf ace water is

very low, 2) the frequency and duration of any contact with surface water would be very low, and 3) the surface

area of skin that potentially could come into contact with contaminated water would be small.
