An investigation into a suspected meth lab in a Fairfield home is wrapping up and charges will likely be filed soon, police said Friday.

On Wednesday, while serving a search warrant on an unrelated matter at 9 Serenity Circle, police allege they found materials used to manufacture methamphetamine, according to Fairfield police Chief Thomas Gould.

The officers contacted the Maine Drug Enforcement Agency, which drew up a second warrant that allowed agents to confiscate the drug materials, police said

Gould said Friday that the investigation will likely lead to charges within the next several days. Police did not release any additional details about the alleged meth lab.

A 2013 state report found that most methamphetamine in Maine is produced from small-scale operations, known as one pot or shake and bake labs, which produce about two ounces of meth at a time.

The number of confirmed meth labs is small, but growing, with state statistics showing a high of 12 discovered labs in 2012, up from just one in 2009.

Each investigation costs more than $15,000 to pay for enforcement personnel, chemical protective gear and hazardous material teams from the Department of Environmental Protection, according to the most recent report from the state’s Maine Methamphetamine Prevention Project.

Gould and state police would not release details about who is being investigated or original search warrant was for, citing the ongoing investigation.

Gould said it’s not unusual for officers who are investigating one crime to be made aware of another.

“You might be there on a theft investigation and notice marijuana or other pills,” he said. “You never know.”
