A site investigation report on testing done in July and October 2019 on a Corry Avenue A landfill has been completed and while contamination levels aren't as high as expected, Department of Environmental Protection's findings include recommendations for more testing.
The DEP had access to the 25 acres owned by the city at the site near the end of Avenue A, past its intersection with Liberty Street.
"The work consisted of the installation of six groundwater monitoring wells, 20 test pit excavations and two quarterly sampling events," the report stated.
EnviroTrac Ltd., of Warrendale, conducted site investigations for the DEP and worked to determine the extent of waste material and evaluate soil, groundwater, surface water and surface sediment.
Surface water and surface sediment sampling also occurred in the adjacent Hare Creek.
Observed at the site were drums, scrap metal, crushed glass, brick, appliances and construction materials.
Among tested sample amounts were 47 soil samples, taken from monitoring wells, including two duplicate samples; seven water samples, collected from select test pits; and 10 soil samples, taken from testing wells.
Found in various samples were contaminants such as arsenic, cadmium, chromium, cobalt, lead, manganese, nickel, benzo(a)anthracene, benzo(b)fluoranthene, benzo(k)fluoranthene, chrysene and dibenzo(a,h)anthracene.
The report submitted from EnviroTrac recommends further testing before remedial action is taken.
While some measurements exceeded certain DEP guidelines for residential direct contact screening benchmarks, there were also measurements that were below medium specific concentrations.
The report noted that all samples collected during the test pit investigation recorded concentrations of volatile organic compounds to be below respective medium specific concentrations, but there were samples that showed levels of metals and semi-volatile organic compounds to exceed guideline amounts.
"Monitoring wells were not installed within the interior of the landfill, therefore, groundwater concentrations within the interior of the site are not known," the conclusions and recommendations section of the report stated.
It continued to say recommendations include an additional two rounds of groundwater and surface water/sediment sampling should be conducted to monitor seasonal groundwater concentrations prior to developing a remediation strategy.
Corry Municipal Authority solicitor Russ Warner explained to authority members that the DEP representatives recommended a meeting before more testing is ordered.
"Shockingly, the DEP and their consultants think while the numbers weren't very bad, they need to do more testing," Warner said. "They need to do a lot more testing."
The proposal in their investigative report is to go back out and drill more pits, drill more wells, take some more analytical tests, but Warner continued to say City Manager Jason Biondi received a notice from the DEP saying the DEP isn't sure exactly what way to proceed and offered a meeting with city officials to talk about Avenue A.
Warner suggested an option may be the city proceed with further testing and remediation efforts with direction from the DEP.
City officials agreed to a meeting to review data with the DEP to see where they stand.
