Next they tested for Trametes versicolor (a white rot fungus), Tyromyces palustris (a brown rot fungus), subterranean termite, and marine borer, and the results showed that among the three tested woods, pine had the greatest resistance to white rot and brown rot fungal attacks, and the polystyrene wood had much greater resistance than untreated wood to brown rot fungi, white rot fungi, subterranean termite, and marine borer attacks.
However, it was revealed that the pilings of the pier were severely comprised by Marine Borer Worms and had become unsafe.
Deterioration of timber members is also due to impact damage, longitudinal and lateral forces, overstressing, drift/ice, poor construction details, insect and marine borer damage, and fire.

Among its credentials, Boswell has been extensively involved in the Port Authority of New York and New Jersey's Marine Borer Monitoring Program over the last six years, providing the Port Authority with a tremendous amount of timber core sampling data and other information related to marine borer biodeterioration rates of attack in various types of treated and untreated wood structures.
