Does Alexandria swap Virginia’s 1.5 µg/100 cm² meth target for a city number?
No. Under the Virginia Department of Health guidelines for buildings once used to make meth, the health-based surface limit stays at 1.5 micrograms of meth per 100 square centimeters. You show certification with accredited wipe tests marked on a floor plan. The guidelines say they are not law on their own. Even so, they are the official after-cleanup target used in certification wording. Smell and fresh paint are not stand-ins.
