With an assumption that these variables are <br /> reasonable and correct, we do not believe that the use of the site would cause a buildup of <br /> nitrates in the ground water over the long term. This agrees with our conclusions stated in our <br /> August 22, 2007 letter for this project. <br /> We appreciate this opportunity to be of service.
