Bradenton Herald | 10/29/2005 | Tallevast plume 'moving fast'

www.bradenton.com [cached]

Graves' data raises serious questions about Lockheed's data and conclusions, said Tim Varney, a scientist with Chastain Skillman and Tallevast's technical consultant.

Varney described Lockheed's monitoring wells as state of the art, but he said the sampling methods used were not adequate to define the plume.Some of Lockheed's monitoring wells were sampled too early after they were drilled, Varney said.In some cases, the wells were not sampled deep enough to tell how far down the contaminants may have sank.
"This data raises serious questions on whether the plume has been fully characterized, both vertically and horizontally," said Varney.
Either way, Varney said, finding 1,4-Dioxane on Booth's property means the solvent has spread far from its source at the former beryllium plant.
Varney said Graves' test data on Booth's well challenges Lockheed's cleanup plans, which currently call for removing solvents in the groundwater beneath industrial site primarily through a pump-and-treat method.
"It would be very hard to remediate a plume extending all of the way to 301 by a pump-and-treat method," said Varney."You could not pump and treat from just one location to remediate a plume this size."
Varney said remediation of the plume would require a distribution of treatment areas throughout the Tallevast community.
"We know 21 of the wells have levels of contaminants that exceed groundwater clean-up standards under the Safe Drinking Water Act," said Varney."Some of those compounds are carcinogenic and some cause systemic health problems."
Factoring those levels into computer programs to measure exposure risk over time would likely indicate significant excess risk, Varney said.
Until that model is constructed, any plans for remediation would be premature, Varney said.

Bradenton Herald | 11/18/2004 | Consultant hired for Tallevast cleanup

www.bradenton.com [cached]

TALLEVAST - Tim Varney can run off a laundry list of professional qualifications, including a bachelor's degree in geology and geochemistry.He holds a master's degree and doctorate in public health.He is a licensed geologist in Florida and a registered hydrogeologist.

He is also certified in handling hazardous materials.
And he's been hired by the community in Tallevast to sift through testing results and other information stemming from contamination from the former American Beryllium plant.
"There needs to be a good sharing of information.Trust within the community has broken down," Varney said.
Varney said he plans to act as an advocate for residents in assuring that the cleanup of groundwater contamination by Lockheed Martin - the company that inherited the old plant - is done correctly.He will also help residents understand the reams of scientific information being supplied about health issues.
Varney is director of health risk assessment with Chastain Skillman, a consulting firm he said has a corporate office in Lakeland but works on projects across Florida and out-of-state.
Chastain Skillman's services includeengineering consultations and aid in dealing with environmental hazards and work and community health issues, Varney said.
In the region, Chastain Skillman has done consulting for schools in Hillsborough and Pinellas counties.Varney confirmed one more recent project in the Tampa area where a group of students became ill, possibly from fumes from a floor refinishing at a school.
"I have been before as many as 12 news cameras in the past," he said.
Varney will be paid by Lockheed Martin, which as part of a consent order with the Florida Department of Environmental Protection agreed to give Tallevast $25,000 per year for a consultant.
And Varney said it is going to be a long journey.To clean up the contamination caused by the plant it could take decades and millions of dollars.But Varney said at this stage all the important players are at the table to get it done.

Tim Varney of Chastain-Skillman recently toured the school and said he did not spot mold growing, but air testing should continue.The portable classrooms also have not been tested yet.

Varney asked parents to give him details about where they saw mold, how bad it was and the types of respiratory problems their children have had.
"We need to keep you better informed about what's going on," he said.

Parents Challenge Studies On Gaither Illnesses - from TBO.com

Timothy Varney, director of health risk assessment at Chastain-Skillman, said he would meet with any of the parents or students to review the chronology of the illnesses to see whether additional information would unearth a cause.

"It's a frustration for us," Varney said.
Varney acknowledged that overexposure could have hurt the girls, but he had no evidence the stridor was linked.
