[and] Ensure that future purchases of alcohol-based hand sanitizers used for infection control contain 60-70% isopropanol and/or ethanol. Specifications for Purchasing to set up a new specific warehouse item are outlined...” (See Memo)
The utility published a factsheet for distribution to its customers explaining, “Concern is growing about the presence in the environment of antibacterial compounds, such as Triclosan, and its chemical cousin triclocarban. Triclosan and triclocarban are common ingredients in many everyday cleaning products such as hand soaps, dish and laundry soaps, personal care products such as toothpaste and mouthwash, and can be found in institutional, clinical, commercial and residential settings. These compounds can be washed down the drain, can persist through wastewater treatment, and make their way into waterways.” Pipeline, 2007
A recent Associated Press investigation, covered by the Washington Post (March 10, 2008) and newspapers across the country identified pharmaceuticals and triclocarban showing up in drinking water.
On July 7, 2008, the advisory committee for Publicly Owned Treatment Works (POTWs) in California, Tri-Tac, submitted comments to the EPA highlighting their concerns about Triclosan and its impact on water quality, aquatic organisms and biosolids. Read their comments here. Tri-Tac is jointly sponsored by the California Association of Sanitation Agencies, the California Water Environment Association and the League of California Cities.
