EPA Approves Colitag E. coli Test System for Drinking Water
|Colitag The First Definitive Water Test System|| |
CPI International, California based manufacturer and marketer of laboratory analysis products, has received the Environmental Protection Agency's (EPA) approval, published on February 13th, 2004 for Colitag, CPI's breakthrough test method for public drinking water under the Total Coliform Rule.
Colitag was developed in the early-90s by George Chang, Ph.D., a professor at the University of California, Berkeley. According to Dr. Chang, Colitag differs from the methods approved by EPA over the last ten years because it can identify E. coli that have been weakened but not killed by water treatments. "If the treatment isn't quite right, you end up with injured pathogens that still may be able to resuscitate in someone's body and cause critical sickness." States Chang. "Any time water treatment breaks down, you have a problem. We look for E. coli that escapes the sanitation process and survives."
