Oregon City Council last week approved a $78,865 contract with ARCADIS U.S. Inc., to test the soil in the city’s right of way adjacent to Envirosafe Services of Ohio, Inc. to determine if contamination is migrating from the hazardous waste landfill.

Envirosafe has, for years, operated its own monitoring wells.

The city’s Public Utilities and Environmental Committee this summer unanimously recommended to council that the city install its own monitoring wells in response to the Ohio Environmental Protection Agency’s Notice of Violations to Envirosafe earlier this year regarding leachate levels in Cell M, Envirosafe’s only active hazardous waste cell, and the inspections of the dewatering trenches and water line trench.
On March 11, the Ohio EPA observed that Envirosafe had failed to operate a pump in the primary leachate collection system sump in a section of Cell M as outlined in its permit, for an extended period of time.

Leachate, or liquid that filters through the landfill, must be removed, tested and managed as hazardous waste.

In addition, the Ohio EPA found that Envirosafe, between at least April 1, 2006 through April 28 of this year, had violated its permit by failing to employ effective management practices, appropriately implement existing written standard operating procedures, accurately record and report to the Toledo Division of Environmental Services and to the Ohio EPA the conditions in the monitoring and dewatering trenches, and provide adequate staff training and oversight.

The City of Toledo’s raw water lines run through the Envirosafe site. The dewatering trenches run parallel to the water lines on both sides. The purpose of the trenches is to collect leachate or storm water that moves through the ground toward the water line trench.

ARCADIS will install monitoring wells at six locations within the rights of way of York Street and Old Millard Avenue.

The monitoring wells will be installed to a depth of less than 20 feet below ground surface, according to an ARCADIS report. Wells will be constructed with two-inch, 10-foot stainless steel screen and PVC casing. The monitoring well screen will be set to intercept both the clay/till interface and the water table.

The water level will be measured within the monitoring wells, and groundwater will be sampled and submitted for analyses of Volatile Organic Compounds (VOCs), and Semi-Volatile Organic Compounds (SVOCs). Gas probes/monitoring wells will be screened with a portable gas meter for the presence of methane, hydrogen sulfide, carbon dioxide, and VOCs.

The results of the investigation will be evaluated and summarized in a technical memorandum. ARCADIS will present its conclusions and make recommendations for subsequent monitoring and/or other actions.

Councilman Bill Myers asked whether ARCADIS was hired without bids from other companies.

“We didn’t bid this work,” said Administrator Ken Filipiak. “We did look at several different firms to perform these types of environmental services for us. In fact, the city has had a long standing relationship for engineering services with Finkbeiner, Pettis and Strout. They were absorbed by ARCADIS. We actually interviewed a couple of firms at the time and settled with ARCADIS mainly because we had a long-standing relationship and certain level of trust with people we’ve dealt with over the years. We originally hired them to review the design of the expansion of Cell M. So they have such a good foundation and working knowledge of that landfill that we can take advantage of it. It wouldn’t make a whole lot of sense for us to change ships in mid stream. Their fees are not extraordinary for this type of work.”

Law Director Paul Goldberg said the city is limited in who it can hire because some local firms have been associated with Envirosafe.

“We’re a bit limited in local firms who can do this work because not many have experience in landfill design, and those that do have worked for Envirosafe. That would be an inherent conflict for them,” said Goldberg.
