Hello, Anhydrous ammonia, which contains 82 percent nitrogen, is the most concentrated nitrogen fertilizer, as well as the “basic” nitrogen product that manufacturers upgrade into other nitrogen fertilizers such as urea and UAN solution. According to my experience once the aquifer is contaminated. its very hard to remove the contamination from it. The best way is to reduce or say stop the overuse of fertilizers.
