|The topsoil I purchased for my vegetable garden smells like it contains sewer sludge. If it does contain sewer sludge is it safe to use for vegetables?

|If it contains sewer sludge it is not recommended for use in a vegetable garden because of the high rate of heavy metals inherent in sewer sludge. It might be that the top soil does not drain properly and that's why you're smelling a foul odor. I'd check with the source of your topsoil to make sure it doesn't contain sludge. Or have a soil analysis done by a private lab before using it to grow vegetables.
