The Impacts of Relying on Desalination for Water – Scientific American

Beyond the links to climate problems, marine biologists warn that widespread desalinization could take a heavy toll on ocean biodiversity; as such facilities’ intake pipes essentially vacuum up and inadvertently kill millions of plankton, fish eggs, fish larvae and other microbial organisms that constitute the base layer of the marine food chain. And, according to Jeffrey Graham of the Scripps Institute of Oceanography’s Center for Marine Biotechnology and Biomedicine, the salty sludge leftover after desalinization for every gallon of freshwater produced, another gallon of doubly concentrated salt water must be disposed of can wreak havoc on marine ecosystems if dumped willy-nilly offshore. For some desalinization operations, says Graham, it is thought that the disappearance of some organisms from discharge areas may be related to the salty outflow.

Of course, as supplies of fresh water dwindle, the economic cost of desalinization‚ especially in coastal areas with easy access to ocean water‚ begins to look competitive with traditional water sourcing. To date there are about 300 desalinization plants in the United States, with 120 in Florida and less than 40 each in Texas and California. Some 20 additional plants are planned for the coast of California in the coming years, unless environmentalists extolling the virtues of conservation and wielding low-flow shower heads and toilets prevail.

  1. More Nuclear Tests u.Never heard of

    1972 nuclear tests on Glade Park shook up earth, residents

    Operation Mixed Company sounds like a title for a movie .
    It was not a movie but the name the Nuclear Defense Agency had given a series of eight nuclear
    blasts scheduled to begin Thursday, June 1, 1972, at 11 a.m.
    Grand Junction had been buzzing with talk about the nuclear test scheduled to take place  on 
    Glade Park about 18 miles southwest of town.
    According to a news report in The Daily Sentinel, the blast went off at exactly on schedule, and 
    within four seconds “a mushroom­shaped, charcoal­colored cloud ascended against the blue sky 
    as the sound and a slight air blast were felt.”
