Investigation Updates
Public Comments being addressed:
OHA staff is currently working to address public comments received on the Public Health Assessment report that was released on May 9, 2013. The report is almost finalized, and is undergoing its last stages of review.
Passive air sampler development: 
EPA is working to develop a passive air sampler that can be deployed in the investigation area. These samplers will be able to monitor the air for the herbicides of interest in the exposure investigation. The monitors have now been tested under laboratory conditions, with hopesto conduct field sampling soon.

Background on air sampling development:
On August 30, 2013, EPA was given an official ‘notice to proceed’. The overall budget for the project, not including EPA staff time, increased from the original estimate of $70,000 to $82,000.  Extra funding was provided by EPA’s Office of Research & Development, through its National Exposure Research Laboratory (NERL), because of the potential for advancing the ability to measure off-target movement of pesticide applications on a national scale.
With NERL’s assistance, some of the technical hurdles were resolved, including the development of a single analytical technique that can detect the different classes of herbicides used in the investigation area. The project was delayed several weeks because of the federal government shutdown.

EPA's Quality Assurance Project Plan (QAPP) for the air samplers was completed in January, 2014.
