Is the CT DPH 0.1 µg/100 cm² figure a mandatory statewide residential law in Darien?
No. The same DPH document says Connecticut has no law forcing drug lab cleanup in an ordinary house. Power to order cleanup does exist for licensed facilities. It also exists if the DPH Commissioner sees a public health threat. Use the number as the official guideline benchmark when you choose to follow state guidance. It does not prove that every house is under a required order. Keep this wording in the property file so buyers are not misled.
