Just think for a minute. Nitrates in ground water may be consumed by a milk cow. The natural process of a cow does not remove nitrates from its' milk. This same milk goes to schools as nourishment for our children. In addition to croppage, I also raise chickens.
Chickens create litter and litter creates odors.
If someone next to an agricultural preservation area is going to spend a considerable sum for a home, they need to be advised beforehand of this fact. They also need to be informed that the farmer has certain rights and protection under the Farmland Preservation Program, to continue his operation. The cost of having to defend an odor complaint in court, could easily run into thousands of dollars. On the other hand we realize that someone who has spent many tens of thousands of dollars for a home, has a right to fully enjoy their lifestyle. The new home-owner needs to be advised with full disclosure beforehand, in order to minimize friction between the homeowner and the farmer.
