Input: An active underground meth lab was uncovered Monday in a storm sewer in the parking lot of the Walmart on Sheridan Drive and Bailey Avenue, Amherst police said. 
  
 Firefighters from both Amherst and Buffalo companies and specially trained state police in hazmat suits were lowered down into the storm sewer Monday afternoon to investigate and clean up the small but potentially toxic lab. 
  
 “We always take precautions because of the chemicals ... The chemicals are highly volatile,” said Detective Lt. JoAnn DiNoto of the Amherst Police narcotics unit. 
  
 Amherst Detective Capt. Scott Chamberlin said police discovered the underground lab while on routine patrol late Monday morning in the vicinity of the parking lot. 
  
 Seized from the manhole were an assortment of aerosol spray cans, various chemicals, plastic soda bottles, jars of clear liquid and suspected methamphetamine, which were laid out on a table under a white tent. 
  
 Chamberlin said there was no way to know how long the suspected drug lab had been in operation, though it is suspected the lab was still in use when police stumbled upon it. 
  
 “It happens all over the country, all over the state,” Chamberlin said of the meth lab. 
  
 “Is it out of the ordinary for Amherst? Has it happened here before? Yes,” he added. 
  
 There were no suspects at the scene when the lab was found and no arrests have been made in connection with the find. 
  
 The area was cordoned off to the public while the investigation and cleanup continued. 
  
 Police will examine video surveillance from outside the Walmart in its investigation of the underground drug lab, Chamberlin said. 
  
 While the term “meth lab” evokes images of a laboratory with bubbling beakers and tubes, the set-ups are usually crude and involve household materials – like cold medicine, lithium batteries, drain cleaner and salt – mixed in containers as common as a two-liter soda bottle. 
  
 In 2012, there was a spike in the number of such labs – nicknamed “one-pot labs” or “shake-and-bake labs.” 
  
 Sgt. Doug Wildermuth of the State Police Contaminated Crime Scene Emergency Response Team explained why they’re so dangerous – and commonplace. The team assisted in Monday’s incident in Amherst. 
  
 “You don’t need a chemistry background to do this,” Wildermuth said. 
  
 The fumes from the cooking method are toxic. “It can be fatal if inhaled enough,” Wildermuth said. 
  
 Some of the substances are caustic and can cause chemical burns. 
  
 But the most dangeous element comes from the metal inside the lithium batteries that are part of the concoction. “If you leave it exposed to air, it will self-ignite,” he said. 
  
 Mixed with a solvent, it can explode. “It will burn so hot, it’s called ‘white fire,’ ” he said.

 They were assisted by the Buffalo Fire Department, the Eggertsville Hose Company and the Brighton Volunteer Fire Department. 
  
 As Walmart shoppers ran their errands, two first responders in full hazmat suits were lowered beneath the parking lot through a man hole. 
  
 “It’s a concern I mean it’s unbelievable in this area, this isn’t a bad area,” said Steve Harding, who lives about two miles from the store. 
  
 Harding was one of a number of people who watched the investigation unfold. 
  
 Amherst Police told News 4 that officers found the evidence in a culvert that runs below the parking lot. They said it’s tall enough to stand up in and it was not secured, so anyone could access it. 
  
 “We’ll talk to the proper authorities to figure out what we need to do to make sure that’s not accessible anymore,” said Captain Scott Chamberlin. 
  
 He said they did not receive any tips. The culvert was checked during a random preventative patrol. 
  
 “Routine patrol, that’s what we do every day,” said Captain Chamberlin. 
  
 We asked him if it’s routine to check underground. 
  
 He said, “We check in various areas that people who might be up to no good, might be using for no good.” 
  
 Members of the NYSP Contaminated Crime Scene Emergency Response Team passed buckets of evidence up from the manhole. 
  
 “Spray paint can, some various chemicals, a liquid we believe is methamphetamine,” said Captain Chamberlin. 
  
 Shoppers watched as the evidence was reviewed in the parking lot. Officials said there was no threat of air contamination or flammability. 
  
 The evidence was placed in white buckets for further tests by Amherst Police. They also plan to look at Walmart surveillance video for clues. 
  
 Captain Chamberlin said they don’t know yet how long this was going on, or who was doing it. 
  
 “This isn’t the kind of thing you’d expect in a place like this, that’s the bottom line,” said resident Steve Harding. 
  
 No arrests have been made yet.

Output:
Police officers stumbled upon a meth lab in an unlikely spot Monday: a sewer beneath a Walmart parking lot in a Buffalo suburb. Authorities say officers discovered the lab, which is believed to have still been active, on a routine patrol in Amherst, per the Buffalo News. Officials in hazmat suits eventually removed aerosol spray cans, chemicals, plastic bottles, and suspected methamphetamine from the sewer, which was tall enough to stand up in, reports WIVB. No suspects were found, though police plan to review surveillance footage. A resident says the discovery is "unbelievable" for the area.
