Environmental cleanup project in Gilford nears completion
GILFORD - A two-year, $13 million project to clean up coal tar dumped in a former sand pit on Liberty Hill Road is nearing completion.
Liberty Utilities said it hauled the last load of contaminated soil earlier this month, calling it a "huge milestone" for one of the largest environmental cleanup projects in the state.
The tar, a byproduct of a manufactured gas plant in Laconia, was dumped on the site with the permission of the land owner at the time in the 1950’s, the company said.
The project, which started in spring of 2014, required the removal and treatment of over 44,000 cubic yards of contaminated soil for treatment.
Each of the 2,662 truckloads of contaminated soil was carefully covered and each truck was cleaned before leaving the site, according to Liberty Utilities. Truck traffic stopped during school bus pick up and drop off times.
The utility company is currently coordinating final backfilling, grading and seeding on the land and expects all site work will be complete by Sept. 23.
