The Sparks resident had been an honor student at Hereford High School, where he graduated in 1989, and graduated cum laude in 1994 from St. Mary's College with two bachelor's degrees -- in physics, and mathematics and computer science.
His family first saw his interest in the environment when he was a child on his family's Parkton farm, where he had what he called "the Machin menagerie," a hodgepodge of pets including rabbits, gerbils, cats, dogs and hamsters. His favorite was Max, a brown dachshund.
"He was a good kid and an excellent student," said his mother, Joyce Marshall Quintavalle of Sparks.
Mr. Machin, in addition to membership in the National Honor Society, played drums in high school and had been a member of Hereford's marching band and jazz band.
While at St. Mary's, he was an intern for two years with the Chesapeake Bay Foundation.
He also enjoyed woodworking and refinishing furniture.
"He'd work for hours at a time," his mother said, recalling a tool chest that belonged to her father, which her son had refinished. "It was my favorite piece he worked with."
Mr. Machin expected to complete a master's degree in environmental engineering next year. He had worked for KCI Technologies Inc., a Hunt Valley engineering company, since 1995.
"He was a much-loved member of the water resource division and excelled in every project," said Terry Neimeyer, president of KCI.
Services will be at 10: 30 a.m. today at Mount Carmel United Methodist Church, 2533 Mount Carmel Road in Parkton.
In addition to his mother, he is survived by his father, Earl Machin III of Glen Rock, Pa.; his stepfather, Richard M. Quintavalle of Parkton; a sister, Tracey R. Capezio of Jarrettsville; and his fiancee, Sharon L. Larrick of Sparks.
