The Marin Municipal Water District has taken another significant step toward building a saltwater desalination facility to stabilize their water supplies, but critics remain adamantly opposed to the project.

Paul Heliker (right), General Manager of the MMWD, believes that the desalination facility is needed to protect Marin residents from possible future droughts and the economic havoc they could cause.

Sharp questions about the safety and purity of the desalinated water were raised again at this week’s water district meeting, but Heliker says those concerns should have been settled by the results of the district’s own tests of the reverse osmosis technology with the same water that the larger plant would use.

Adam Scow, California Deputy Director for water programs for the national consumer advocacy group, Food and Water Watch, is among the vocal skeptics who question the need and cost of the proposed desalination plant. He points to a report commissioned by his organization that disputes the underlying assumptions the district uses to make its case for the project. You can read that report here.

For its part, the district has prepared a 9-page slide show on their desalination project, which is much easier to digest than the full Environmental Impact Report, which is posted here. At left is a map showing where the proposed plant would be situated.

Sonoma County business leaders appear to feel the worst is over, economically speaking, and are beginning to express cautious optimism about the future.

Ben Stone, (left) Executive Director of the Sonoma County Business Development Board, cautions that significant challenges still face important sectors of the local economy, notably in commercial real estate, tourism and the wine industry.

The Business Confidence Index is compiled 2-3 times per year, and has been an ongoing project of the EDB for nearly 10 years.  The most recent level is shown in the chart below, which tracks that history.

The current overall confidence reading of 4.6 (on a scale of 10) is a rebound from last winter’s low of 3.62. But the current figure is still below the 2001 trough recorded just after the 9-11 attacks, and well below the three-year readings around 6 from 2004 through 2006. That history is among the charts included in the most recent full report, which you can read here.

Exposure to toxic chemicals in our environment begins early in life--even before birth.

  Ken Cook, President and co-founder of the Environmental Working Group, is a strong proponent for a Kids-Safe Chemical Act, to reduce children's exposure to toxics in the environment.

 Additional online resources from the Environmental Working Group  include the Shopper's Guide to Pesticides, and their Cosmetic Saftety database.

The Environmental Working Group is also pressing for the creation of a human "toxome," similar to the genetic map known as the human genome, to identify where and how toxic chemicals affect the body's healthy biological processes.

The Sonoma-Marin commuter train faces a pivotal decision this week, as its directors choose the type of rail cars they will design the rest of the line to match.

The SMART Board of Directors Meets on Wednesday, July 15 at 12:30 pm in the Sonoma County Board of Supervisors chambers to consider the railcar purchase and other business.

The regulatory standards set by the US Federal Railroad Administration are the biggest single factor shaping SMART's choice for new rolling stock (as railroad cars are often called). SMART General Manager Lillian Hames explains those standards are especially stringent in situations where freight and passenger trains share the same set of tracks.

The global financial woes of the past year are also affecting SMART, Says Hames, particularly their plans to issue bonds against future sales tax revenues. They are hoping to bridge the funding gap with grants, cost savings in planning and construction, and other measures.

One of the variables tied to the choice of rail vehicles that SMART will use is the height of the floor height above the tracks, which is a function of such design considerations as fuel tank placement and structural engineering. The difference could be 24 inches or more, but either way, the passenger loading platforms at each of the 15 stations along the line will have to be built to match the train's floor level, so that wheelchair users can easily access the cars. These new platforms, says Hames, will likely look quite different than the wooden decks seen along historic train stations.
