The hit AMC TV series, Breaking Bad, gave us a glimpse inside a methamphetamine cook’s world. The main character, Walter White, was a chemistry teacher turned drug kingpin who started cooking meth to support his family and pay for expensive cancer treatments. White’s actions eventually led to his own demise, and the death and destruction left in his wake was telling.

Probably the most disturbing takeaway was the realization that a meth lab can exist just about anywhere; in a moving car, in a basement, in a stolen Winnebago, or even in a state-of-the-art underground laboratory beneath an industrial laundry facility.

So who is responsible for finding and cleaning up the Meth?

Let’s Talk About Meth

According to the US Drug Enforcement Administration’s Methamphetamine Lab Incidents list there were 11,210 clandestine laboratory incidents in 2012. This is down from 13,390 in 2011. Missouri leads the country at 1,825 incidents in 2012. Right behind them is Tennessee at 1,585 and Indiana at 1,429. New York, California and Texas report 147, 79, and 32 busts respectively.

But these numbers can be deceiving.

Some methamphetamine labs literally go up in flames as fires and explosions are telltale signs of chemistry gone bad. However, most go undetected by police. In reality, law enforcement busts only a fraction of clandestine laboratories. So what happens to undetected labs and what are the procedures for identifying contamination and cleaning the structures to so they are safe for re-occupancy?

This first step is identifying the danger. Here are some things to watch for before entering a suspect structure:

Police Activity: Check with local fire and police departments and inquire about recent clandestine laboratory activity in the area.

Pungent Odors: The chemicals used in or created by meth production result in very strong, highly toxic odors.

Unkempt Property: Many meth labs are unkempt and in various states of disrepair. Burns on hard surfaces and countertops, dirty furniture or a lack thereof, leaky roofs, and visible drug paraphernalia are red flags. Yellow staining on walls and drains, and irregular areas of dead vegetation near the property are also common.

Chemical Containers: Look for chemical debris scattered throughout the area. This might include glass containers, funnels and tubing used in the cook process as well as empty bottles of acetone or paint thinner, ammonia in propane tanks, iodine, hydrochloric acid, phosphorous, drain cleaner bottles, kitty litter and packaging from over-the-counter medications that contains pseudoephedrine.

Check with the DEA: The US Drug Enforcement Administration’s National Clandestine Laboratory Register lists the street address of known methamphetamine laboratories by state, county and city. Remember this list only includes properties documented by law enforcement.

Know the Dangers

Before the cleanup process can begin, it is important to know the dangers of possible worker exposure. Meth labs are highly toxic chemical mine fields. Fire and explosion pose an immediate risk due to the volatile compounds used in production. Entering a meth lab before proper assessment by law enforcement,or before proper testing and cleaning, can cause symptoms ranging from coughing, nausea and dizziness, to chemical burns and even death. Routes of exposure from meth lab chemicals occur thorough inhalation, absorption or direct skin contact, and ingestion.

“Entering a meth lab … can cause symptoms ranging from coughing, nausea and dizziness, to chemical burns and even death.”

Besides the chemical dangers surrounding a meth lab, there is also the danger of booby traps intended to protect inventory. Emergency responders report finding gasoline-filled light bulbs that ignite with a flip of the switch, hidden trip wires connected to tear gas grenades, and even explosive devises packed with broken glass. Take extreme caution when working in or around a known lab.

Who Regulates Meth Cleanup?

The Environmental Protection Agency (EPA) does not officially regulate the cleanup of meth labs but does provide Meth Lab Cleanup Guidelines for reference. California’s Office of Environmental Health Hazard Assessment (OEHHA) also provides technical support documents and fact sheets. Many states have an independent procedural and clearance mandate for re-occupancy. Links to state regulatory data can be found in the appendix of the Meth Lab Cleanup Guidelines.

Cleaning up the Meth: a 12 Step Process

Below are some of the EPA’s recommended clean up procedures:

1. Secure the property
2. Ventilate
3. Assess & Test, Scope of Work
4. Develop a Cleanup Plan
5. Remove Contaminated Materials
6. Vacuum
7. Preliminary Washing of Hard Surfaces
8. Clean and Seal HVAC system
9. Thorough Detergent-water Washing
10. Consider Encapsulating Walls & Ceilings
11. Flush Plumbing & Septic Systems
12. Clearance Testing

Step 1: Secure the Property

If a structure is suspect, do not enter the building but instead allow local law enforcement and first responder hazmat teams to remove toxic and hazardous drug paraphernalia and chemicals. After this is complete, the testing and remediation process can begin.

Contractor / Worker Safety
Personnel who enter a former meth lab should have safety and health training. Appropriate personal protective equipment (PPE) such as masks, protective eyeglasses, heavy gloves, foot coverings, steel toe boots, and long-sleeved coveralls or a disposable protective suit must be worn.

Step 2: Ventilate

Air out meth labs with fresh, outdoor air by opening doors and windows and using fans, blowers or a negative air unit with HEPA filtration before during and after the remediation process. HVAC systems should be completely shut down before and during the remediation process to avoid re-contamination.

Step 3: Assess & Test, Scope of Work

Why do pre-remediation sampling? Pre-remediation sampling can reduce costs by streamlining the cleanup process and identify materials that are too contaminated to clean. Pre-remediation sampling can also can be useful in identifying uncontaminated areas. An industrial hygienist with proper certifications should perform sampling. All rooms serviced by HVAC systems should be considered for testing.

“There are two different types of testing for methamphetamine, qualitative and quantitative,” says Mike Powers, senior environmental consultant at California-based environmental testing and consulting company, Envirocheck Inc.. “Qualitative testing is a test that can be performed on site and indicate if there is Meth residue on a surface or not, Quantitative testing will indicate residue, if present, in micrograms analysis, which is very important for achieving clearance levels for re-occupancy.”

“Quantitative testing will indicate residue, if present … which is very important for achieving clearance levels.”

Many states have certain quantitative meth remediation standards ranging from 0.05 micrograms / 100 square centimeters to 1.5 micrograms / 100 square centimeters. The most common standard is 0.1 micrograms / 100 square centimeters. California’s Department of Toxic Substance Control (DTSC) set a health-based remediation standard for meth at 1.5 micrograms / 100 square centimeters.

Pre-remediation testing is important for many reasons. It can ensure safety of workers and determine levels of PPE necessary. It establishes whether or not contamination levels exceed state and local requirements and if remediation is necessary. Sampling can also show the reach of the contamination and present a scope of work for remediation contractors for developing cost estimates. It can also highlight other hazardous materials relevant to the reconstruction process like asbestos and lead.

Step 4: Develop a Cleanup Plan

Use the scope of work provided by the environmental consultant to formulate a plan for cleanup. The plan should show security concerns, status of utilities on site, levels of PPE for workers and a shoring plan if structural integrity is an issue. Outline cleanup methods including removal v. cleaning, encapsulations if any, and procedures for on-site and off-site contamination including a waste disposal plan.

The scope of work provided by the environmental consultant should show pre-remediation and post-remediation sampling methods along with the list of personnel taking samples.

Step 5: Remove Contaminated Materials

The EPA suggests gross removal followed by 24 hours of ventilation and removal of all meth paraphernalia. This is when the determination is made to clean or discard contents.

Consider the following:

Potential for human contact: Take extra care with children’s items. Frequent hand to mouth contact, or higher metabolic system and developing nervous system make children more vulnerable to toxic chemicals including those present during remediation activities from asbestos and lead contaminants

Intrinsic or emotional value of irreplaceable items and photos

Porosity: Porous items are much more difficult to clean and are often discarded

Hazardous or non-hazardous waste disposal: Meth lab waste can not go in landfills according to the Resource Conservation and Recovery Act (RCRA)

Follow asbestos and lead disposal guidelines

Step 6: Vacuum

Vacuum the floors with a commercial grade HEPA filtered vacuum after removal of carpet, floor pads, walls and other hard surfaces. Standard canister or non-commercial grade vacuums are not recommended. In addition, vacuum walls to remove dirt and cobwebs prior to washing. This step will remove particulate contamination but will not remove contamination entirely.

Step 7: Preliminary Washing of Hard Surfaces

After items have been removed and vacuumed, wash walls and hard surfaces using a detergent water solution. This helps prevent re-contamination during the remediation process. Bleach specifically should not be used in the cleaning process as the reaction between bleach and the chemicals used in producing meth can create a toxic gas. Consider testing wash water to determine if it qualifies as hazardous waste or can be disposed of onsite.

“Bleach specifically should not be used in the cleaning process as the reaction between bleach and the chemicals used in producing meth can create a toxic gas.”

Step 8: Clean and Seal HVAC system

Shut down the HVAC system immediately and leave it off during the remediation process. Sample all areas and rooms serviced by the system to determine the spread of contamination. Test ducts to determine the scope of contamination. Cleaning can be difficult as many times duct work can be porous and can re-contaminate the structure after remediation is complete. Cleaning methods should be left to the discretion of ventilation contractors but experts agree that no chemicals should be added to disinfect ducts.

Step 9: Thorough Detergent-water Washing

Use a household all-purpose cleaner, following manufacturer concentration guidelines, starting with the ceilings, walls and finish with floors. Clean other hard-surfaced items like counters and furniture. Clean the entire surface using either hot or cold water and repeat each wash with a thorough rinse using clean water and a clean cloth. The use of harsh chemicals is not advised as many of the pre-cursor chemicals used in meth production can have adverse chemical reactions. Bleach, for example, can become very toxic.

Step 10: Consider Encapsulating Walls & Ceilings

Sealing contaminated walls and surfaces with primers and paint can provide a protective barrier but should be in conjunction with proper cleaning techniques. Several states recommend that products applied to encapsulate surfaces be sprayed on and not hand-rolled.

Step 11: Flush Plumbing & Septic Systems

Meth chemicals are frequently poured into sink drains and flushed down toilets. As a result, plumbing systems can be compromised via corrosion or even become flammable. Flush plumbing traps with generous amounts of water during the cleaning process and again after remediation if wash water is disposed of onsite. Sinks, bathtubs and toilets with visible discoloration and etching should be disposed of.

Large amounts of chemical waste can be problematic if they remain in septic systems or private wastewater systems often found in trailer parks or apartment complexes. If there is evidence of contamination, an industrial hygienist should sample the tank for volatile organic compounds (VOCs) and/or pH levels outside the normal range. Expert field screening should be used to evaluate septic system contamination. Remediation of septic systems should be done last.

Step 12: Clearance Testing

It is very important to show cleanup effectively reduced contamination. Check with local governments to determine re-occupancy clearance levels. If cleaning does not meet the state standard, the site should be cleaned again, or encapsulation or removal should be considered.

A Dirty Job

The process for detecting and cleaning a clandestine methamphetamine lab is not only wrought with hazards, but it is also a very slow and meticulous process. More and more remediation and environmental companies are finding the need to educate workers in this niche market.

“There is a need for increased awareness in the field of methamphetamine testing and remediation,” says Vinh Pham, Envirocheck’s Vice President of Operations. “It is a specialized process that requires proper training and expertise.”
