I’m trying to identify possible risks and harm that can come by moving into a home that had a meth lab in it. My sister-in-law and brother-in-law have purchased a house via sheriff sale in Pennsylvania outrightly that among other things is believed to previously have had a meth lab. They are refusing to get a home inspection. They have 3 children and twins on the way. I’m seriously concerned about the possible health risks, especially to the newborns. If any one can direct me to any kind of information or resources that I could pass on to them, I would greatly appreciate it.
