In 1997, Trinity Foam and Fiber, a manufacturer in Glenola, North Carolina, was closed by the state because air and groundwater contamination exceeded accepted levels.  Residents had begun reporting health problems and noxious fumes more than 15 years earlier.  In the mid 1990s, state and federal agencies tested air and wells surrounding the company and issued several public health notices.  This case marked the first time a North Carolina Health Director formally declared a company a public health nuisance.
