Suspecting or discovering that your property is contaminated with methamphetamine (meth) can be alarming. QUEST has extensive experience assessing properties for meth impacts and can guide you through the sometimes complex process, step by step.
Meth assessment is regulated state by state, and QUEST’s assessments fully conform to each state’s regulations and guidelines to minimize our clients’ risk and liability. For all assessments, QUEST provides a formal report that fully complies with the relevant state’s requirements. In Colorado, QUEST is fully qualified to conduct the three types of meth assessments prescribed by our state’s regulations:
- Screening Level Assessment
When no meth contamination is known or suspected—such as during a typical real estate transaction—QUEST recommends a Screening Level Assessment. Our team conducts a limited sampling survey with fewer samples than required for clearance of a known-contaminated property. If test results show no meth, or if all detected concentrations remain below the state’s screening level of 0.2 µg/cm², no further action is necessary. If results exceed the screening level, QUEST advises the property owner on the most effective path to achieve regulatory compliance.
- Preliminary Assessment
When meth contamination is known or suspected, QUEST performs a Preliminary Assessment. Depending on the property’s history, sampling may or may not be required. We design the most cost-effective sampling strategy that still meets state requirements. Sampling helps define contaminated areas, guide decontamination efforts, or confirm that certain areas remain unaffected. If decontamination becomes necessary, QUEST directs clients to Colorado’s decontamination standards and coordinates with the chosen contractor to ensure the best results.
- Clearance Level Assessment
When decontamination has already occurred, or when contamination proves less severe than expected, QUEST conducts a Clearance Level Assessment. We collect a thorough set of samples according to state regulations to confirm meth concentrations fall below cleanup criteria or remain non-detectable. If needed, we oversee additional decontamination and re-testing until the property clears. Local authorities rely on QUEST’s Clearance Level Assessment report to determine when a property is safe for re-occupancy. In some jurisdictions, the county or municipality may also conduct its own clearance sampling before granting final approval.
Consultants and decontamination contractors must be state-certified to handle meth projects in Colorado. Although we hope to earn your business, even if you don’t choose us, please ensure that your sampling and clean-up personnel are meth-certified if your property is in Colorado. The list of certified individuals and companies, including QUEST, is provided by the State of Colorado here. Further information on meth assessment is provided by the State here.
