Scott,
Pham is right. You really do want to steer clear of heavily used boating areas and marinas. If it is your ONLY choice, I would suggest testing the water, and testing it again. Also, if I were restricted to collecting in this type of area, I probably WOULD filter the water. The biggest concern with that jetty (nice area by the by) would be petroleum based pollutants from boats AND the fact that (honestly now) you can NOT guarentee that EVERYONE in that marina is using the pumping station (as madidate by law) in emptying their heads. Seriously...it's a nasty thought, but it happens everywhere.
Finally, at a strapping 38 years old, I'D NOT want to haul buckets up and down that breakwater. It'd kill me
See if you can find a pal with a boat, or another area that has less boat traffic. I'm not so sure that a captain would let you take buckets out on his fishing party boat, but you could try!
