Mark is a chemical analyst that graduated from Ball State University in 1999 with a major in chemistry and a minor in geology. He made the Dean’s List in every semester that he attended BSU with a GPA of 3.86.

Mark joined the team at HML, Inc in 1999. He is the chief metals chemist. He tests for lead and arsenic in drinking water using a graphite furnace atomic absorption instrument. GFAA is also used to test antimony, selenium, and thallium. He uses an inductively coupled plasma instrument to analyze drinking water, wastewater, land application, and TCLP samples for metals. The ICP is used to test for copper and IOC metals (barium, cadmium, chromium, beryllium, nickel, and sodium) in drinking water. Some of the main elements he uses the ICP to test for in wastewater are copper, nickel, zinc, lead, cadmium, chromium, and silver. He also uses a cold vapor atomic absorption instrument to analyze for mercury. Some of his other responsibilities include using colorimetric methods to test for nitrite, sulfate, and sulfide in drinking water and TKN in wastewa
