Public Notice Ripon Farm see • September 2012 <br /> Treatability Study <br /> A pilot scale treatability study will <br /> be conducted at the Site. During <br /> this study, a carbon rich substrate 9¢ <br /> will be injected into the shallow g99 <br /> groundwater to observe its <br /> effectiveness in reducing the nitrate <br /> concentration in groundwater <br /> beneath the Site. The proposed pilot <br /> scale treatability study will be FEcuae z `' <br /> centered at two locations on the Site, <br /> near Monitoring Well MW-103 and MW-104, and will help to develop a treatment program for the <br /> entire site, which is shown in Figure 2. <br /> The carbon rich substrate is the proprietary product, EHC®-Carbon Only(a product from FMC <br /> Environmental Solutions), which will be injected into the shallow groundwater. The carbon substrate <br /> will stimulate biological activity,which will change nitrate to nitrogen gas. Nitrogen gas comprises <br /> about 80% of the atmosphere we breathe. <br /> Additional information is in the Treatability Study Work Plan, which is available on Geotracker, an <br /> internet information site, or can be provided to you by either of the contacts listed below. <br /> Using Geotracker <br /> To see the Treatability Study Work Plan, or other Ripon Farm Service documents on the internet, go to <br /> http://geotracker.waterboards.ca.gov.
