  • New York towns want safe water during GE's dredging of PCBs in Hudson River (Troy Record, May 25) 
    Commentary: Citizen concerns about resuspension of PCBs into drinking water from the Hudson River are heightened as GE falls short of everyone's expectations for preventative measures during the billion-dollar cleanup. Increased carbon usage is proposed but is not acceptable to local officials who want an alternate piped supply. And what's a few million dollars more?

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.
