Overview of Chapters
- Chapter 1: Environmental Issues
- Chapter 2: Environmental Effects on Real Estate
Impact of Environmental Issues on Real Estate
- Increased public awareness and concern about environmental problems have significant consequences on:
- Real property value affected by:
- Actual environmental issues
- Perceived environmental concerns
- Marketability of property may decline due to environmental hazards.
- Costs for cleaning up environmental hazards may exceed the property's dollar value.
Environmental Property Hazards
- Hazards may occur:
- Externally (outside the property)
- Internally (within the property)
- Common contemporary environmental hazards:
- Poor indoor air quality
- Asbestos
- Lead
- Radon gas
- Carbon monoxide
- Mold
- Chlorofluorocarbons (CFCs)
- Chlordane
- Urea formaldehyde
- PCBs
- Methamphetamine remnants
- Underground storage tanks (USTs)
- Groundwater contamination
- Waste disposal sites
- Pests
Indoor Air Quality (IAQ)
- Definition:
- IAQ refers to the quality of air inside and around buildings, especially concerning the health and comfort of occupants.
- Controlling pollutants is essential to reduce the risk of indoor health concerns.
- Symptoms of Poor IAQ:
- Immediate after exposure:
- Irritation of eyes, nose, and throat
- Headaches
- Dizziness
- Fatigue
- Symptoms may be short-term and treatable.
Sick Building Syndrome (SBS)
- Definition:
- Term used for situations where occupants experience discomfort related to time spent in a building without identifiable illness.
- Common Symptoms:
- Headaches
- Eye, nose, or throat irritation
- Dry cough
- Dry/itchy skin
- Dizziness
- Nausea
- Fatigue
- Sensitivity to odors
- Symptoms typically resolve upon leaving the building.
Asbestos
- Definition:
- A naturally occurring mineral fiber used in insulation and various building materials for its heat resistance.
- Uses Include:
- Insulation, roofing shingles, ceiling/floor tiles, paper products, friction products, automotive parts, etc.
- Exposure to Asbestos:
- Occurs when asbestos-containing materials are disturbed (e.g., during renovation).
- Health Effects:
- Increased risk of:
- Lung cancer
- Mesothelioma (rare cancer)
- Asbestosis (non-cancer lung disease)
- Safety and Testing:
- Only professionals should handle asbestos sampling and abatement.
- States govern asbestos removal procedures; untrained individuals should not attempt removal.
Testing Methods for Asbestos
- Bulk Sampling:
- Small portion of material collected for lab analysis.
- Air Monitoring:
- Air is tested through filters for asbestos fibers.
- Wipe Sampling:
- Surfaces are wiped with filters to collect dust for analysis.
Professional Actions for Asbestos
- Possible actions:
- Repair: Encapsulation/sealing or enclosure to prevent fiber release.
- Removal: For significantly damaged materials.
Carbon Monoxide (CO)
- Definition:
- An odorless, colorless gas produced by incomplete combustion of fuels (wood, oil, gas).
- Symptoms of CO Poisoning:
- Headache
- Dizziness
- Weakness
- Upset stomach
- Chest pain
- Confusion
- Legal Requirement:
- Residential and commercial buildings in Georgia require working CO detectors.
Radon Gas
- Definition:
- Odorless radioactive gas from the decay of natural minerals in the earth.
- Entry Points into Homes:
- Cracks in floors/walls, construction joints, gaps around pipes, etc.
- Health Effects:
- Long-term exposure increases lung cancer risk; radon is a primary cause among non-smokers.
- Testing Recommendations:
- Homes should be tested for radon every two years, especially in known radon areas.
Mold
- Definition:
- A fungus that thrives in damp environments, can release toxins.
- Signs of Mold Growth:
- Fuzzy patches, discoloration, or musty odors.
- Health Effects:
- Allergic reactions, respiratory issues, and severe reactions in immunocompromised individuals.
Chlorofluorocarbons (CFCs)
- Definition:
- Chemical compounds harmful to the ozone layer; used previously in coolants and aerosols.
- Regulation and Safety:
- Banned in the 1970s; Clean Air Act regulates disposal procedures.
Chlordane
- Definition:
- Formerly used pesticide banned in the U.S. due to health risks.
- Health Effects:
- Gastrointestinal distress and neurological symptoms; classified as a probable human carcinogen.
- Definition:
- Insulation that releases formaldehyde, a potential carcinogen.
- Health Risks:
- Causes respiratory issues and irritations.
- Regulation:
- Banned in residential construction due to health concerns.
Polychlorinated Biphenyls (PCBs)
- Definition:
- Synthetic organic chemicals used in numerous industrial applications until 1979.
- Health Effects:
- Associated with various health risks; exposure should be handled by professionals due to toxicity.
Methamphetamine (Meth)
- Definition:
- Highly addictive illegal drug that poses health risks associated with home production (meth labs).
- Health Effects:
- Toxic gases affect air quality; professional cleanup is often required.
Pests
- Common Pests:
- Insects and rodents causing damage to properties.
- Specific Examples:
- Bees: Professional removal advised; declining populations.
- Carpenter Bees: Create structural holes in wood.
- Termites: Cause significant wood damage; hire professionals for treatment.
- Carpenter Ants: Leave behind sawdust; need professional control.
- Bedbugs: Cause skin irritation; identification is key to proper treatment.
Pest Management and Real Estate
- Pest infestations must be disclosed during real estate transactions.
- Advise clients to address pest issues proactively before marketing the property.
- Escrow or warranty provided by professionals for pest remediation is ideal for sellers.
