Groundwater Documents

Omya monitors its groundwater by sampling and testing wells and surface water stations located throughout the plant site. In an effort to share the information collected at these sites, Omya is making its August 2005 Groundwater Monitoring Plan and December 2005 Groundwater Sampling Report available to the public through our website.

Odor Study Documents

In response to community concerns, Omya initiated an effort to identify the source of odors released from Omya’s plant operations. Omya selected TRC as the consulting group to manage this 3 phase effort by performing a preliminary study, odor testing, dispersion modeling, air testing and health risk assessment. TRC has completed the first two phases of the Study.
