I walked that beach everyday, early am when few were awake.  My doc told me that there was a higher percentage of brain cancer in that area than any other place in the west coast.  There is a business area sitting on another side of the cliff area and you could see flow from pipes run freely into the ocean.  

Huh. .  What a total shame.  They built up that hill (I lived on top of the cliff overlooking Nye bch) w/houses w/out any true plan of waste control.  I have difficulty describing all this geo stuff but trust me: Newport from 2000-today focused more on development and lots of wealthy folks built there and nothing on needed infrastructure to sustain that growth.

It's really the same ole same ole.  We'll never learn and that's heartbreaking.  Think of all the lives and jobs lost over this.

 ps?  There's radioactive stuff too from Japan.   I'd collected dozens of glass floats from Japan for years and know for sure debris from Fukoshima ended up there
