UCI Professor Stanley B. Grant has authored a letter which Blake Anderson happily sent out to all Directors who might need influencing...or was it Hans Christian Anderson?


"Finding the Primary Causes of Coastal Pollution"
[by Stanley B. Grant, Professor of E. Eng. Dept. of Chem. Eng. and Material Sciences UCI]

"Most people believe that more should be done to protect our coastal ocean and eaches...three years of beach postings...have left the public frustrated that the surf isn't clean, and spawned growing rancor over whether [OCSD] should upgrade to full secondary treatment..."

"As a scientist...I think that the debate over secondary treatment is...secondary..."



"Full secondary treatment would reduce the levels of organic contaminants, viruses and bacteria, released to the ocean, but so far there is no evidence that the extra treatment, at a nominal cost of $400 million, would make ... water problems go away. What's more, sewage treated to full secondary standards still harbors enough viruses and bacteria to pose a significant health risk to recreational bathers if the plume comes ashore."

"So what's the solution? The sanitation district's plan to partially disinfect their sewage is a good start...Unlike secondary treatment, disinfection targets the...protozoa, bacteria and viruses...at a fraction of the cost of secondary treatment. It's also a great experiment..."

"...street runoff is a far greater threat to coastal water quality than the sewage plume..."


One wonders if Prof. Grant realizes that the initial cost of the chlorination "experiment" would be $8 million per YEAR, plus $5 million or more in monitoring and testing expenses for more oceanographic studies, tests and surveys; whereas the $400 million "nominal" cost of giving up the waiver would be a ONE-TIME capital outlay via tax free sewer bonds (which OCSD has a ready market for) at a rate of about 3%, according to one recent annual report.

So chlorination really comes in at a minimum of $13 million, even without building chlorination/dechlor detention tanks, and full secondary comes in at $12 million interest costs per year.

Maybe the economics profs should review these cost numbers, in the full outside audit that OCSD is due?
