EPA ID# WID056247208

Site Description

The 16-acre Lemberger Transport and Recycling site (LTR) is located in Manitowoc County, Wisconsin, approximately one-quarter mile from the affiliated Lemberger Landfill site (LL), also a National Priorities List site.  LL and LTR are also near the active Ridgeview Landfill. Farm and wide spaced rural residences that utilize groundwater for drinking are near the site. The area is used for hunting. The nearby Branch River is used for swimming, fishing, and canoeing.

LTR operated as an unlined disposal area from 1970 to 1976. Wastes disposed included an estimated 900,000 gallons of wood tar distillates, paint wastes and other industrial wastes.  

 

Site Responsibility

In 1985, WDNR replaced residential wells where VOCs were detected with much deeper wells. U.S. EPA funded the Remedial Investigation/Feasibility Study. A group of potentially responsible parties names the Lemberger Site Remediation Group (LSRG) have implemented the cleanup actions under U.S. EPA and WDNR oversight.

Threats and Contaminants

The groundwater, underlying and extending as far as 1.5 mile downgradient from LTR is contaminated with VOCs primarily including 1,1,1-trichloroethane, 1,1-dichloroethane, 1,1-dichloroethylene, trichloroethylene, and cis-1,2-dichlroethylene.  A number of residential wells are located in this area.  Direct contact risks have been addressed by construction of a multi-layer site cover including a geomembrane. 

 

 

Cleanup Progress

In 1985, WDNR installed replacement wells for seven residences. These wells are cased to 250 feet below ground surface.

From 1987 - 1993, U.S. EPA conducted a Remedial Investigation/Feasibility Study to determine the extent and nature of contamination and to identify cleanup alternatives. In 1991, U.S. EPA deferred the remedy selection for the LTR source area and selected a groundwater pump-and-treat system to cleanup the groundwater.  In 1992, the LSRG entered into a consent decree with U.S. EPA to implement the final cleanup, including: groundwater pump-and-treat; deed restrictions; and, in accordance with a 1993 administrative order, locate, remove, and dispose of drums, construct a fence around the site, construct a multilayered soil cover over the site, and conduct soil vapor extraction.  In November 1993, the LSRG installed a six-foot chain-link fence around the LTR. By November 1994, PRPs excavated, staged, bulked (as appropriate), and disposed of 1380 drums and 180 jars. Because investigations indicated that soil vapor extraction would not be effective, this technology was not implemented. In 1995 - 1996, the PRPs constructed the pump-and-treat and site cover, and initiated operation of the pump-and-treat system. In 2001, the PRPs added four pumping wells to the pump-and-treat system, and operated the pump-and-treat system until August 2008.

From August 2006 through August 2008, the LSRG conducted a monitored natural attenuation (MNA) study, which included a temporary shut-down of the pump-and-treat systerm.  EPA has allowed continued shut-down of the pump-and-treat system because operating the existing system provides little benefit.

In the 2010 five-year review, EPA made a number of determinations, largely based on the MNA study, including: the groundwater monitoring plans need to be updated; the existing pump-and-treat system had limited effectiveness because a substantial amount of highly groundwater from LTR was not being captured; there had been deficiencies in operation of the pump-and-treat system; release of VOCs to groundwater from LTR will continue from LTR for a very long period of time; it would not be appropriate for EPA to accept MNA as the major component of the groundwater cleanup; contaminant entry into Branch Creek needs to be evaluated; and options to improve the pump-and-treat system need to be evaluated. At this time (January 2011) the LSRG under EPA and WDNR oversight is developing updated groundwater monitoring plans, a plan for additional aquifer testing to determine whether the pump-and-treat system can be improved, and an evaluation of whether continued leachate withdrawal is necessary. WDNR staff have determined that contaminant migration into Branch Creek will not cause a significant threat to fish or wildlife. 

 

 

Community Involvement

U.S. EPA recently issued a notice for the 2010 five-year review. 

Property Reuse

The site owner entered an Environmental Protection Easement and Declaration of Restrictive Covenant with the LSRG restricting usage of groundwater, and disturbance of soils. Groundwater in the vicinity of the contaminant plume is restricted through State of Wisconsin Regulation NR 812.09.
