The AWWA Distribution System Water Quality Committee is embarking on revisions to their M56: Fundamentals and Control of Nitrification in Chloraminated Drinking Water Distribution Systems.  The M56 manual is a complete guide to managing nitrification and is intended to be a principal technical resource for water system operators throughout the US.

PAX Water Technologies presented a technical talk at the 25th annual Association of State Drinking Water Administrators meeting last week in Pittsburgh, PA entitled Stabilization and Improvement of Distribution System Water Quality in Reservoirs and Tanks – a Key to Stage 2 Compliance.

The AWWA held a webinar on October 6, 2010 entitled Sustainable Water Quality Management within the Storage Tank: Part 2 (you can listen to a rebroadcast here).

We learned this week that an engineer (who shall remain unnamed) presented a paper at the DSS meeting in Maryland about water age modeling in which he claimed that mixing CANNOT decrease water age. 

The EPA recently announced a new strategy to provide clean, safe drinking water and a novel means by which those of us in the water industry, and citizens in general, can comment on it: an on-line discussion forum.

We recently spotted this news item: U.S. EPA Categorically Approves Water Main Automatic Flushing Devices For Green Project Reserve Funding.  The Green Project Reserve (GPR) program identifies technologies that improve practices to deliver equal or better services using less water.

It is well known that disinfectant residual levels drop as potable water makes its way through the distribution system.  It is also generally believed that the rate of disinfectant loss is a function mainly of time – as water sits in the distribution system, the residual is consumed as it reacts with naturally occurring organic matter.

Temperatures are expected to top 100 degrees across much of the Eastern seaboard this week and municipalities large and small will be contending with managing their water quality. 

Are you going to ACE10 next week in Chicago? PAX Water Technologies will be there.

It's every municipality's worst nightmare: a wildfire erupts on the boundary of your community, and every available resource must be deployed to fight it.
