My brother is currently living in Hawaii studying leptospirosis. Wiki Definition of leptospirosis: The infection is commonly transmitted to humans by allowing water that has been contaminated by animal urine to come in contact with unhealed breaks in the skin, eyes or with the mucous membranes. He's a scientist (I'm proud of him). He sent me this pic taken by his G10 (I'm jealous of his camera). And his description below...Caught this rainbow over hanalei bay, looking southwest, early in themorning. The bay stays pretty calm in the summer. Some people stayanchored there for months at a time. It's controversial though becausethe anchors damage the reef and many of the boats dump there sewage intothe bay. But actually, most of the homes in the bay are on a septicsystem and when they get a lot of rain (which happens all the time) theseptic tanks back up and spill over delivering there share of"nutrients" into the bay. The added nutrients increase bacterial loadsin the bay, and also increase algal blooms which and can deplete oxygenlevels in the water ultimately damaging the reef and therefore the wholesystem.Some groups argue that the town needs a sewage treatment plant or elsethe bay will continue to degrade as a result of aging septic systems.Others argue that a treatment facility will allow for furtherdevelopment of the bay and ultimately impact the region even more.
