Residential methamphetamine contamination in Boulder, Colorado: Incidence and implications

Area of Science:

• Environmental Health
• Public Health
• Toxicology

Background:

• Methamphetamine (meth) production and use lead to property contamination, creating health hazards for occupants and significant remediation expenses.
• Despite regulations in states like Colorado, the prevalence of meth-contaminated residences exceeding safety standards remains largely unknown.
• Current meth testing typically occurs only after a property is suspected of contamination, limiting proactive identification.

Purpose of the Study:

• To determine the incidence of meth contamination in residential properties using a unique dataset from a real estate broker's screening program.
• To estimate the prevalence of homes exceeding established meth contamination standards in Colorado.

Main Methods:

• Utilized data from 303 residential properties under contract between 2013 and 2022.
• Screened 288 (95%) of these properties for meth contamination.
• Conducted comprehensive testing on 35 properties with detected meth and analyzed results against Colorado's contamination standard (0.5 µg/100 cm²).

Main Results:

• Meth was detected in 16% (45 of 288) of screened properties, often at trace levels.
• 10 properties (3.47% of 288) exceeded the Colorado contamination standard of 0.5 µg/100 cm².
• Specific levels exceeded: 9% > 0.05 µg/100 cm², 6% > 0.1 µg/100 cm², and 2% > 1.5 µg/100 cm².

Conclusions:

• The study provides a realistic estimate of meth-contaminated residential property incidence.
• Findings indicate a significant public health concern regarding meth contamination in homes.
• Proactive screening is crucial for identifying and mitigating meth contamination risks in residential properties.
