How GemChem got started

Larry Gemmell was working in the petroleum fuels distribution business in the late 1970s to early 1980s when the EPA regulations were quickly changing to require companies to properly dispose of hazardous and residual waste.  During his time in the petroleum fuels distribution industry, many of their customers were inquiring as to where & how they can properly comply with these new environmental regulations.  Larry saw an opportunity and had an idea of starting a company to assist these companies with complying with environmental regulations.  In 1980, GemChem was founded by Larry Gemmell.  He began the business as a one-man operation then incorporated in 1985, acquired a building in Lititz, PA (which is still one of our buildings today), hired employees and obtained the necessary permits from EPA/PADEP to operate. The rest is history…  GemChem, Inc. has since grown to a company that services over 300+ customers in (5) different states.  Larry Gemmell passed away in October of 2014 and is missed by many people but his dream and legacy live on in our company.
