The Boron standard in many wastewater treatment and pretreatment standards
is based on the level of Boron that will cause spotting on tomatoes
irrigated with water above that level. Be sure to determine how a level
was set, i.e., whether to protect human health or some economic interest,
before applying the standard in a possibly inappropriate way.
