California is investing $3 million in an effort to allow researchers to predict when and where ocean waters near Imperial Beach may be contaminated. The ocean off the coast of Imperial Beach has suffered decades of contamination which includes trash, toxic chemicals and untreated sewage runoff. Last week, homes in Imperial Beach, Chula Vista, San Diego and on the Silver Strand were under a boil-water order because a test sample came back positive for E. coli contamination. The order was lifted this past weekend after additional tests found the water to be safe.
