Pall-Gelman Contamination Site Concerns
Need to define plume
The first step to solving a problem is to fully define it.
Where is the plume vertically and laterally, which ways is it going and how fast?
Develop reliable model of plume by checking model predictions vs. actual readings and use to refine model.
Need consistent, reliable datasets of well data, sampling data, and discharge data.
Full Cleanup Not Possible within 5 Years
Neither Pall-Gelman nor the DEQ is informing the court that the 5-year deadline (July 2005) is unrealistic.
If cleanup is terminated prematurely because of the 5-year deadline, too much 1,4-dioxane will be left to spread to water supplies in coming decades.
No more water supplies with detectable levels of 1,4-dioxane
Use model to position purge wells where they will halt the plumes.
Add sufficient treatment capacity to do community-acceptable cleanup.
Community-Acceptable Cleanup
Review local government resolutions.
Summarize consistent community-acceptable criteria.
Right to Know
Community has right to know where plumes are at level of detect (i.e. 1 ppb)... not just at the erstwhile 'acceptable level' of 85 ppb.
Breakdown byproducts need to be sampled periodically at the influent and effluent at roughly the same ppb level as the 1,4-dioxane in the discharge.
Citizen/Local Government Participation in Cleanup Decisions Critical
Termination of citizen participation in cleanup decisions since 1996 has resulted in a weaker cleanup.
Citizens and local governments need to be a formal part of the cleanup review/decision making process.
Local governmental/citizen reviews need to be scheduled and their objectives defined.
