Chief Operator Keeps Groundwater Cleanup Plants Running

MASSACHUSETTS MILITARY RESERVATION, Cape Cod, Mass. — U.S. Navy veteran Bill Bearce was looking for a challenge.  He found it in plumes of contaminated groundwater emanating from the Massachusetts Military Reservation (MMR).   He now has the overall responsibility of keeping the eight systems operating that clean 12 million gallons a day of groundwater contaminated long-ago with spilled fuel and solvents.

Bearce saw lots of water while serving aboard communication relay ships in the Navy from 1963 – 1965 on cruises through the north Atlantic, the Caribbean, and off the coast of the Dominican Republic.  But to get to the present point in his career after leaving the Navy in 1966, the former military electronics technician first had to gain a lot of experience.  He was a civilian computer maintenance field engineer for Honeywell Systems for 15 years and then for 10 years with National Computer.  He even ran his own computer maintenance business until a waning industry and a new found interest in science put him on a course that would lead him to Cape Cod.

Bearce sees his present job with CH2M Hill as “working with your hands and your mind.”   He uses the combined skills of an electrician, plumber, painter, groundskeeper, carpenter, mechanic, electronics technician, computer operator/technician, building custodian, inventory clerk and tour guide in his position as chief operator.  Each member of the operations and maintenance crew he supervises must have these skills, too.   They – and Bearce – are also certified wastewater treatment plant operators.

Bearce got his start in the environmental field at the Baird and McGuire Superfund site in Holbrook, Mass., in 1995.  He operated a Thermal Destruction Unit for OHM Corporation.   The equipment removed contaminants from soil by using extreme heat.  The resulting vapors were passed through scrubbers and a secondary combustion chamber before being released to the atmosphere.  “You had to have water to cool the stack gas and to quench the soil,” he says of the unit that ran at temperatures reaching 2000 degrees Fahrenheit.

“It was a very complex site,” says Bearce.  “I asked myself ‘What did I get myself in for?’  But my computer background helped me understand it.  And I learned about water treatment there.”

He became so interested in the cleanup process that he took a class that earned him a state certification in water treatment.  It was soon after that he heard about an opening coming up at Jacobs Engineering on the MMR.  In January 1997, he began his now eight-year association with the Air Force Center for Environmental Excellence on the MMR.

The treatment plants under Bearce’s supervision today operate 24 hours a day, 365 days a year.  The systems utilize 37 granulated activated carbon vessels, each holding 20,000 pounds of carbon.  He has overseen the treatment of more than 20 billion gallons of groundwater contaminated with solvents and fuel.  Treatment changed the contaminated water into water clean enough to meet federal and state drinking water quality standards.

Bearce feels that he’s “doing something worthwhile in his job.”  “When we put the treated water back in the ground, it’s drinking water quality.”

His other duties include daily checks on the operation of cleanup systems, performing scheduled maintenance, and maintaining the wells that pump the contaminated water to the treatment plants.

Once the untreated water is pumped into the plant, Bearce ensures the water is sampled for contaminant content in three locations:  where untreated water enters the plant; between the vessels containing the activated carbon that cleans the water of contaminants, and where treated water exits the plant.  Sampling determines the treatment efficiency and when to “change out” or exchange the carbon.

The changing of a total of 740,000 pounds of carbon in the 37 carbon vessels is part of Bearce’s responsibilities.  The frequency of the changes depends upon several factors, including the amount of contamination in the water and the number of gallons of water pumped per minute.  He’s seen a total of 6 million pounds of activated carbon used since 1997.

As precise and accurate as Bearce is in his work, inconsistencies and facts-not-proven have touched his private life.   His very name is involved in a clouded interpretation of local genealogy and spellings.  He may be a descendant of “Princess” Little Dove, granddaughter of Iyannough, the sachem of the “Mattachee Village of Wampanoags of Cape Cod,” according to a “Bearse” family web page.  “My family can’t verify it, but it sounds interesting,” says Bearce.  He does have cousins in Falmouth, though he lives in Medway.  Bearses Way in the town is named after a distant relative, says Bearce.

What is proven, though, is that more than a half billion federal dollars have been spent since 1982 on the Air Force program to clean up groundwater and soil contamination caused by past practices on the Massachusetts Military Reservation.  The Air Force expects to spend another $350 million in the next 20 - 30 years to complete investigations, design and construct treatment systems, and keep them operating.

Bearce and his operations and maintenance staff have a continuing responsibility.  They ensure that as the groundwater treatment plants and wells age and require more maintenance, they continue to be fully operational.  “The plants have to run,” he says.
