This week's NEWS

Salmonella-plagued Colorado city status upgraded to "okay to boil and drink" from "do not use."   Specific organism identified... in Australian publication. Canadian question: How long do boil water advisories need to stay in place... and why? What will new bottled water certification mean? Water treatment news ranges from missing UPS device to routine switch away from chloramines, while Des Moines, IA, faces fertilizer-ammonia problem. There are lots of ways to skin the arsenic cat (with apologies for the non-PC terminology)... but building a water treatment plant and not operating it isn't one of them. "I didn't really say THAT, did I?"

Colorado Salmonella Outbreak

  • Specific pathogen identified (Australian Health Streams, March)
    Commentary: "As of 25 March the only pathogen reported to have been identified from fecal specimens of victims was Salmonella enterica serotype Typhimurium. This bacterium is a common cause of enteric illness and is frequently associated with foodborne outbreaks. Waterborne outbreaks due to Salmonella species are relatively rare, accounting for only 15 outbreaks out of over 300 with identified microbial agents occurring in the U.S. from 1971 to 2002. Salmonella enterica serotype Typhimurium can be carried by a range of animals and birds as well as by humans. The time lag between ingestion of Salmonella and development of symptoms such as diarrhea or vomiting generally ranges from about 12 to 72 hours. Definitive identification of the organism in stool samples requires up to seven days, so it is probable that the water contamination event in Alamosa may have occurred a week or more before recognition of the first cases in the community, even if people visited a doctor promptly after becoming ill."
  • State replaces "do not drink" order with "boil all water" advisory 
  • No "new" news since the last state update (Denver Post, April 3)

Malcolm Pirnie is prepared to help utilities deal with water treatment plant optimization challenges.

For more information on these services, please read our brochure, or contact Laurie Sullivan at lsullivan@pirnie.com.

 

Radium

Lead

  • Ohio schools fail to report or act on high lead test results (Akron Beacon Journal, April 6)
    Commentary: In the category of quotes that any public figure would love to take back when he sees them in print: "...principal at Burbank Elementary School, north of Wooster, said he didn't fully understand his legal obligation to notify the public. 'I wasn't, I guess, overly concerned about it,' he said, referring to the unsafe lead level detected in school water in September. 'I wouldn't look at it as an immediate life-and-death situation.'"

Perfluorochemicals

PPCPs

  • New York City council pushes for testing of city's water supply for PPCPs (New York Times, April 4)
    Commentary: The council suggested that the city should not wait for the federal government to take action, and the city's top water official assessed the relative lack of risk:
    "...the amount of pharmaceutical compounds detected is so small they could not even be detected until advanced technology was developed a few years ago. 'A person would have to drink one million glasses of water to get the dose of even one over-the-counter ibuprofen tablet or the caffeine in one cup of coffee,' ... 'Even at eight glasses of water per day, this would take the average person over 300 years to consume.'"

Invasive Species

Volatile Organic Chemicals

Methane Gas

Bottled Water

  • Underwriter Laboratories launches a new certification program for bottled water (UL news release, March 31)
    Commentary: The details of this new program to put the "mark" of UL on bottled water products that meet the requirements of both the FDA and the IBWA have not been examined. It will be interesting to know how the program will work, especially with regard to ongoing regular monitoring of the sources, treatment, and bottling processes, as well as the quality of the water in bottles on the shelf. (The extent to which these activities are carried out by FDA or its state surrogate agencies is not clear.)
