Landfill testing shrinks

WASHINGTON — The latest round of testing to evaluate the condition of ground water at the Industrial Excess Landfill in Lake Township targeted only half as many monitoring wells as last fall, officials said Monday.
In the testing at the 30-acre Superfund site, 25 monitoring wells were sampled, down from 51 during the previous round of testing in November, said Tom Shalala, an environmental consultant working for the Lake Township trustees. The weeklong testing ended Friday.
Lake Township officials and the four companies paying for the cleanup had agreed to retest only those wells that showed contamination during the November tests, said Paul Wolford, spokesman for Goodyear, BF Goodrich, Bridgestone-Firestone and GenCorp.
“Over half of the wells historically and during the last two rounds have had almost no hits of any contaminants of concern,” he said.
Previous testing has detected contaminated ground water within the landfill. No contamination has been found outside the landfill in recent testing.
The latest round of testing also looked for radiation contamination. The previous two rounds did not find radiation contamination beyond normal “background” levels.
Results of the latest testing are expected in six weeks to two months.
The U.S. Environmental Protection Agency validated the results of the August tests, but has not yet confirmed the results of the November tests, said Ross del Rosario, EPA remedial project manager.
EPA officials said the planned removal of seven to eight underground storage tanks filled with fuel oil and other substances, and at least one septic system, could begin as soon as next month and be completed in May or June. Plans call for the demolition of three abandoned buildings in the same area on the west side of the landfill.
Federal officials expect to make a final decision later this year on a proposal to cover the landfill with a “phyto-cap” made up of trees that would soak up rainwater, preventing it from reaching contaminants
buried at the site and carrying them to ground water.
