Pond Boss Forums POND CONSTRUCTION Selecting a site Pond near ag land - concerns?

theo quick answer here but I think for the most part I'm correct. No way to bioaccumulate herbicides/pesticides. That is with PCB, heavy metals, etc. Many of the chemicals used are also used for aquatic use and they could not get the labels approved without testing fish tissues first.

So I think the use of herbicides upwatershed would not be major concern however as Trent said if too much nutrients the pond might be in trouble. Here in the SE it can sometimes be a blessing b/c it helps lack of nutreint situation.
