Understanding Arsenic

Arsenic poisoning is a major concern across the world. Naturally produced arsenic in drinking water has poisoned millions in Bangladesh as highlighted in a recent SLAC public lecture, but it is not only a problem in developing countries. Arsenic is a concern in the United States as well, especially in Michigan, Wisconsin, Minnesota, and the Dakotas.

Many variables influence how arsenic travels the water table, including iron oxides in the soil. Researchers from Stanford's Soil and Environmental Biogeochemistry group are now using the Stanford Synchrotron Radiation Laboratory (SSRL) to study how chemical and biological factors, including bacteria and PH levels affect the structure and reactivity of iron oxides. Because the iron oxides can affect the transport of arsenic, their work is one step towards understanding how arsenic travels through an ecosystem.  Read more...

CEF's John Weisend to Temporarily Transfer

John Weisend and Liam Robinson.

Conventional and Experimental Facilities Department (CEF) Head John Weisend is striking out for new territory—but it's not good-bye, it's see-you-later. Weisend will take a temporary position at the National Science Foundation (NSF) in Virginia beginning in late June.

As part of the Intergovernmental Personnel Act (IPA), Weisend will work in the NSF's Large Facilities Projects Office, reviewing new and existing projects in a variety of scientific fields. This temporary transfer program offers Weisend the chance to learn about broad issues in Washington, D.C.

Weisend, who has worked at SLAC for 8 years in roles ranging from head of the cryogenics group to head of CEF, will remain an employee of SLAC, but will work for and be funded by the NSF.

"I'm looking forward to Washington, learning more about the NSF, and taking knowledge learned here to Washington, while bringing skills and experience gained at the NSF back to SLAC," said Weisend, who will return to SLAC after 12 to 18 months.

Weisend is leaving his position in the very capable hands of Liam Robinson, who is currently the CEF Facilities Support Group Leader. According to Weisend, Robinson's job has provided more than enough experience for the step up.

"I am proud to lead such a talented and dedicated group," said Robinson. "My vision is to deliver expert facility services to support scientific programs in a safe and professional manner."

ES&H Celebrates Revision of Manual

The Environmental Safety and Health (ES&H) Division hosted an ice cream social yesterday afternoon to celebrate the completion of the new ES&H Manual, which contains all the lab's safety requirements. The revisions were based on a review of operations, benchmarking with other Department of Energy laboratories, new regulatory requirements and with the intent of making the Manual more relevant and easier to use and maintain.

"SLAC has reached an important milestone in updating the ES&H Manual chapters," said Sayed Rokni, ES&H Division Acting Associate Director. "Just as important was the establishment of a successful process where subject matter experts and stakeholders from line organizations come together to complete a project."

Over the past two-and-a-half years the ES&H Knowledge Management Department has worked with program managers, safety coordinators, laboratory leadership, and stakeholders across the site to revise and publish 49 chapters and more than 300 supporting documents.

The next phase in this effort will focus on shaping and targeting content more closely for specific users and tasks, based on an assessment of the just-completed work, further peer benchmarking and review, and customer feedback.

All details about the ES&H Manual are online on the ES&H Manual website.
