Creating a stink.* The neighbors of a Scranton, Pa., C&D landfill have been complaining about a strong odor coming from the site, and initial investigation by environmental authorities shows the cause may be gypsum gypsum (jĭp`səm), mineral composed of calcium sulfate (calcium, sulfur, and oxygen) with two molecules of water, CaSO4·2H2O. It is the most common sulfate mineral, occurring in many places in a variety of forms. in the landfill causing the "rotten egg smell." According to the Scranton Times, two mobile laboratories from the state's Department of Environmental Protection (DEP DEP Deposit DEP Deputy DEP Department of Environmental Protection DEP Dependent DEP Departure DEP Depot DEP Deposition DEP deployed (US DoD) DEP Data Execution Prevention (computer security) ) were at the Environmental and Recycling Services Inc. (ERSI ERSI Environment Remote Sensing Institute ) landfill to identify the source of a widespread, sulfur-type odor. The action followed less than a week after the department issued an administrative order to ERSI demanding the landfill correct the problem. ERSI was reportedly working cooperatively to fix the problem. ERSI's landfill is next to an old, closed municipal solid waste “Municipal waste” redirects here. For other uses, see Municipal waste (disambiguation). Municipal solid waste (MSW) is a waste type that includes predominantly household waste (domestic waste) with sometimes the addition of commercial wastes collected by a (MSW (MicroSoft Word) See Microsoft Word. ) landfill, and both were being checked to determine the source of the problem. ERSI has been using odor-masking chemicals and has added cover soil as means to combat the gypsum odor if it has been, in fact, causing the problem. The landfill remains in operation. |
