Mary Ley, Laboratory Supervisor

Mary has been at KCL since 2009.  Prior to working for the City, Mary worked in Research and Development at Warwick Mills in New Ipswich.  She also taught general chemistry laboratory sections at Franklin Pierce University.  She graduated from the University of Wisconsin-Madison, with a degree in chemistry.   She worked in a waste water treatment plant laboratory for five years in Madison, Wisconsin before moving to New Hampshire.

Mary is responsible for the day to day supervision of the laboratory and most of the instrumental analysis. She tests for metals using an atomic absorption spectrometer (AA) and quantifies and separates compounds using ion chromatography. She also keeps track of the reams of paperwork required for recordkeeping. Mary ventures out frequently for field sampling expeditions for groundwater monitoring, waste water samples and drinking water samples.

Donna Hanscom, Laboratory Manager/Assistant Director Public Works

Donna has managed the City’s laboratory since its inception in 1985. She moved to Keene from southern Maine, where she was the laboratory director for a small independent environmental laboratory. She graduated from University of New England (St. Francis College) in 1981, with a BS degree in Environmental Analysis.

Donna developed monitoring programs for water and wastewater programs. She works with members of the NH Department of Environmental Services (NHDES) in teaching classes in laboratory quality control to other wastewater treatment plants, and has participated in workshops and conferences on both water and wastewater issues.
