From CCIM Institute:
…environmental risks commonly associated with the sale, purchase, ownership, and redevelopment of commercial real estate are:
- contaminants produced from known and unknown historical operations;
- construction debris containing hazardous materials;
- sick building syndrome, which can be carbon monoxide, mold, legionella, or other bacterial air releases resulting from faulty heating, ventilation, or air conditioning systems;
- hazardous chemical storage such as laboratory chemicals, medical wastes, dry cleaning solvents, and pesticides;
- lead, asbestos, polychlorinated byphenols or PCBs, and radioactive material;
- “midnight dumping” on vacant land parcels;
- contaminated surface-water run‑off; and
- leaking underground or above-ground storage tanks or piping.
