[beachnet] sewage spill on a beach: CupriDyne Treatments

Hello Ken,

What is the general chemical composition of CupriDyne? From its name, it appears to contain copper. USEPA has developed water quality criteria due to copper's broad-spectrum toxicity to a variety of aquatic/marine species: http://www.epa.gov/waterscience/criteria/copper/ 

Also, is it registered for the types of applications suggested below under FIFRA as a pesticide/biocidal agent by USEPA?

Thanks in Advance,

Kim Ward

Eric,

We are the sponsors of the UCLA beach-sand remediation experiment done by
Jenny Jay, and showcased by her at the EPA conference in Niagara Falls. Dr.
Roger Fujioka is repeating these trials on carbonate sands in Hawaii, and
both experiments are delivering 3-5log10 reduction of total bacteria counts
in minutes by using low dose CupriDyne (free iodine), without regrowth.
This approach also immediately eliminates foul odors as well. and we are
marketing this aspect into animal barns, as an example.

Our Iodine is GRAS by FDA between 20-80 ppm, and is considered natural,
since oxidative and non-oxidative forms of iodine precipitate from marine
rains, and accumulate to levels around 50-60 ppm in the US and Canada at the
coast and near environs.

It sounds like you have about an acre of beach involved, so we recommend
CupriDyne be mixed into an inch-acre of water (27000 gallons total) and be
applied in a single "rain" at 60 ppm (a single flood or bolus).

If this is of interest to you, since I am in Canada, I am copying my US
office in Irvine, CA with this memo, and we will be happy to send you what
you need at a wholesale cost.

Please contact Dennis Calvert at 949-235-8062.

I will supply written instructions if you decide to go ahead, and tell me
the volumes of flood water you will prepare at a time.

Happy to help.
