I wish I only had a dandlion problem. My neighbor retired from the railroad, and his wife retired as one of the top people at the bank. They also own a farm. Nice vehicles, campers, boats etc, but they are to cheap to upgrade their septic system. When they pump it they try sneak the hose into my yard. A few years ago the high nitrogen killed four colorado blue spruce about 16 inches diameter. I reported it and what come out of his wifes mouth would make a sailor blush. They were given a year to upgrade. That was five or six years ago. I hauled in truckloads of black dirt so that corner of my yard is to high now. At least my camper isnt standing in six inches of his septic run off now. It nowruns through the west sde of my yard and into the Jamestown resivoir. I would think that would violatr all kinds pf laws.
