This week's NEWS

Tucson water quality to be sculpted to satisfy consumers' taste and pocketbooks. Politics and drinking water standards get intermixed at state level (also!): It's alachlor in Wisconsin and economic value of health benefits in California. Get connected by RSS to CDC emergency bulletins on quality threats and issues. What are the sources of perchlorate in the U.S. food supply? Not everyone is happy with Congress' interim appropriations measure to address security of chemical facilities.

Federal Updates

State Updates

  • Wisconsin legislature blocks state's attempt to set drinking water standard for alachlor; Monsanto's lobbying for more study cited (Wisconsin State Journal, September 28)
  • California Governor vetoes proposed SB 187 (PDF files, 9.6 K and 93.2 K) that would have added additional requirements for the state's MCL-setting process. Reaction to the veto (Daily Bulletin, October 2)
    Commentary: One provision of the proposed amendments to California's existing prescriptive law on setting drinking water standards is the following: "The department may also consider, to the extent information is available, as a part of the determination of economic feasibility, the potential affects (sic) on human health that may result from the adoption of a primary drinking water standard that is less stringent than the public health goal."  Determining the actual, incremental effects at these very low levels is a challenge; putting any realistic cost value on the tiny increment would be daunting.

Malcolm Pirnie Membrane Filtration Services

 The promulgation of the Long-Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) established the first federal regulatory framework for membrane filtration, including microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO) systems applied for rule compliance. Many states are expected to adopt this framework for membrane regulation as well.

Working in conjunction with the USEPA, Malcolm Pirnie has been involved in the development of the Membrane Filtration Guidance Manual in support of the LT2ESWTR. As a result, the company has in-depth expertise with respect to the new regulatory framework and how it will be applied to both new and existing facilities. Malcolm Pirnie can lend its unique experience to provide assistance throughout the project development process, including planning, piloting, equipment procurement, design, construction, and start-up, to ensure system compliance.

For more information, please contact Brent Alspach at BAlspach@pirnie.com.
