Steve Thurman - September 26, 1986 2. As you should know, a letter has been written to Mr. Fredenberg about controlling the runoff from the silage stack. As a temporary solution for this year, it was requested that a pit be dug at the low end of the stack to collect the juices and then it is to be hauled out to the nearby fields. In addition, since it appears that silage may have been dumped directly on top of the well in the truck unloading process, he was advised to provide temporary barriers around the well . Lastly, he was advised to keep pumping the well to waste in an attempt to purge the well of any silage contaminants that may have gotten in. Furthermore, he was advised that a lined holding pond or basin would be necessary to collect the silage juices if a similar stack is planned for next year. Your attorney, Mr. Brill , received a copy of that letter. A copy of it is enclosed for your file. On the day of my inspection, samples were collected for bacteria, nitrates, and several inorganic chemicals in an attempt to determine if the well had been impacted by the silage juice run-off from the stack or from the dumping of the silage from the trucks . As you can see from the attached result, the well sample was determined to be bacteriologically "unsafe". In addition, a subsequent sample taken on September 5, 1986, was also determined to be bacteriologically "unsafe". The other analyses for nitrates and the other inorganics have yet to be received but they will be forwarded to you once the analyses are completed by the State Lab of Hygiene. As I explained to you by phone on several occasions, the present renters have been informed not to use the water because it was bacteriologically "unsafe" and because silage juice contamination of the well may have occurred. However, even if this contamination did not exist, the present well location is not acceptable. The Private Water Supply Code (NR 112) stipulates certain minimum separation distances between a well and known pollutant sources in the area. Presently, the well is located only 18 inches from a yard hydrant having a drainback provision. The present code separation distance is at least 10 feet from such a hydrant. Even more importantly, the well is located too close to the silage unloading area, the above ground silage stack, and the above ground stave silo. Presently, a minimum separation distance of at least 50 feet is required between the well and a conventional silo with a pit. The code also requires that the well be located on the highest point on the property consistent with the layout of the premises. Certainly the existing well is not in such a location. For these reasons , the Department is requesting that a new well be constructed in a proper location which is far enough away from all of the pollution sources on the property. Based upon my inspection of the area, it appears that a proper location might be to the north of the existing home. A registered well driller in Wisconsin should be contacted regarding a new well , and he could provide you with a proper location and will explain what will be needed. Once the new well is completed and in use, the old well must be properly abandoned by filling the well entirely with concrete from the bottom upward. This could be done by using
