EPA Zone
Zone 2
Louisiana is mostly Zone 2 with lower radon potential. The Mississippi Delta's sedimentary geology doesn't produce significant radon. Some northern parishes show moderate readings.
📋 Testing recommended
Even in Zone 2, the EPA recommends testing every home. Radon varies house by house — your neighbor's low reading doesn't guarantee yours is safe.
Top Indoor Air Hazards in Louisiana
Mold Exposure
HIGH RISKMold releases spores that trigger allergies, asthma attacks, and respiratory infections. Black mold (Stachybotrys chartarum) produces mycotoxins linked to neurological symptoms.
High Indoor Humidity
MODERATEHumidity above 60% creates ideal conditions for mold, dust mites, and bacteria. It also increases off-gassing of VOCs from furniture and building materials. The EPA recommends 30-50% indoor humidity.
Formaldehyde (VOC)
HIGH RISKFormaldehyde off-gases from pressed wood furniture, flooring, and new construction materials. It is classified as a known human carcinogen by the IARC. Levels are highest in new or recently renovated homes.
Louisiana Climate & Air Quality Factors
Year-round extreme humidity makes Louisiana the #2 mold state. Hurricane flooding causes catastrophic water damage. Older French Quarter and plantation homes have lead paint and asbestos throughout.
