Received a desperate phone call from rural property owners whose neighbor was paid to take sewage sludge from a nearby large municipality (industrial & hospital waste sources would be included). Apparently the incinerator was shut down - this is unprocessed sludge. It was applied 4x/year over a 2-year period at a rate of 15 Tons/acre over a 300-acre property. The odor during application was unbearable, and they continue to get whiffs of it when it is damp outside. Odor has been described as rotten fish, dead bodies, sour, lime, and medicinal. DNR reportedly agrees it is an issue, but currently does not have regulations to do anything; sludge tested ok for nitrates & heavy metals according to DNR. The property owner was so sick that they abandoned their house. Health symptoms were vomiting, diarrhea, watery eyes, and burning nose. Symptoms went away after they left the property, but they return as soon as the owners return to their property. Livestock of other neighbors have reportedly died, and others have experienced animal birth defects. They are trying to build a case for a civil lawsuit. There is surface water drainage from the neighbors property that they would like to sample, but don't know what to test it for. They also suspect the dust from the sludge has been deposited everywhere. What does everyone think about a sampling approach/parameter list? They do not have access/permission to sample the sludge directly.
