Chemical Oxidation Remediation at the Former Western Industries Site Completed
North Shore Environmental Construction (NSEC) successfully completes in-situ chemical oxidation remediation at the former Western industries site in Menomonee Falls, WI on August 15, 2012.
The remediation project completed by NSEC was successful in conjunction with the outstanding efforts contributed by Orin Remediation Technologies and KPRG & Associates. New development of the site is expected to start construction in September, 2012.
North Shore Environmental Construction to perform Clandestine Lab emergency response services
North Shore Environmental Construction (NSEC) has partnered with Drug & Laboratory Disposal, Inc. (DLD) to provide federally funded Clandestine Lab emergency response and cleanup services in the state of Wisconsin. In partnering together, NSEC and DLD intend to leverage NSEC’s knowledge and expertise in emergency response cleanup, with DLD’s expertise in Clandestine Lab Waste Management. Federal approval and startup of this new service is expected by September 1, 2012. Wisconsin Law enforcement personnel should contact their regional DEA Clandestine Lab Coordinator to request service.
NSEC contracted by Bradley Corp to provide emergency response for 10 gal. organic peroxide spill.
MENOMONEE FALLS- TODAY’S TMJ4 is reporting that four people were injured after a 10 gallon drum of organic peroxide ruptured at the Bradley Corporation on Main Street near Highway 41.
Those four people are employees of the Bradley Corporation and are expected to be OK — but have been taken to a local hospital as a precaution Tuesday afternoon.
Hazmat crews have responded to the organic peroxide spill which happened around 2:45 p.m.
Authorities told TODAY’S TMJ4 that about two-thirds of the facility has been cleared as “safe.” They are still investigating how the drum ruptured.
The company has about 380 employees and they have reportedly been told to go home for the day.
The Bradley Corporation is a manufacturer of washfountains, plumbing fixtures, emergency fixtures and washroom accessories.
North Shore Environmental is awarded $2.5 million in-situ chemical oxidation project
North Shore Environmental is awarded $2.5 million in-situ chemical oxidation project at the former Western Industries site in Menomonee Falls, WI
North Shore Environmental Construction will start the project on April 17, 2012. The remedial action objective is to treat (in-situ), using chemical oxidation, up to 6018 cubic yards of soil within the clay/silty clay unit to non-hazardous levels for TCE which will allow for off-site disposal of the soils to a local Sub-title D landfill. The remedial action is being directed by KPRG Inc. a local engineering/consulting firm out of Brookfield, WI. It is estimated the project will be completed in approximately 3 months from the start of the project.
NSEC removes mercury from school gymnasium in Iowa
North Shore Environmental Construction was low bidder ($287,000.00), on the mercury contaminated floor removal, at the Wright Field House gymnasium in Keokuk, Iowa. NSEC was awarded the project on February 27, 2012 by the Keokuk Community School District.
The project started on March 12, 2012.
NSEC first had to remove the 18,000 sq. ft. wooden maple floor with a 1/2’” tartan floor underneath. Once the floor was removed, an additional 5/8” of asphalt was scarified to complete the cleanup.
The floor was contaminated because of the tartan underlay, which was laid down in the 1970’s. Also, it was contaminated with a mercury bi product to help the floor cure, during the drying process. The mercury eventually migrated into the maple floor along with the asphalt.
NSEC used specialized equipment to remove the contaminated floor. NSEC used a crew of 9 Technicians, and completed the project on March 22, 2012, 8 days ahead of schedule.
The project generated (11) 30 yard roll off containers during the removal. The material was shipped as a hazardous waste to Belleville, Michigan where it was micro encapsulated for disposal.

GYM FLOOR WORK TO COST MORE THAN EXPECTED
By Megan Spees/Staff Writer
The Keokuk School District has to dig deeper into its wallet than previously anticipated, in order to get rid of the old floor at Wright Fieldhouse.
At its Feb. 27 meeting, the school board awarded a contract for athletic flooring abatement services at Wright Fieldhouse to the lowest bidder, North Shore Environmental of Germantown, Wis.
According to Project Manager Jamie Rochleau of Story Construction, abatement bids far exceeded the $80,000 originally budgeted due to inherent risk and the time frame.
“We talked to a couple of the (bidding) contractors … and they couldn’t get comfortable enough with the scope of work that was in front of them,” Rochleau said. “So in order to become comfortable with it, they increased their bid.”
North Shore’s bid came in at $287,280, still more than the adjusted project budget of $240,000.
“Do they think they’ll have a problem with the time frame?” board member Mike Beaird asked.
“No. As a matter of fact I think they plan on, once they mobilize, working around the clock to get it done,” Rochleau replied.
He said that removal of the floor should be done around March 30, followed by additional demolition inside the fieldhouse that would include tearing out and replacing the asphalt slab.
Environmental testing indicates that mercury has seeped into the asphalt layer. Most landfills won’t accept that kind of material, which is why it’s being hauled to Detroit, Mich. Transportation has become another factor in the rising cost of abatement.
Board member Alka Khanolkar noted the uncertainty of what might be found under the U-drive when it’s remodeled.
“What do we have left?” she asked.
“From a contingency standpoint? We’re pretty much wiped out,” Rochleau said.
Reynolds said, “With regard to what we had initially allocated for contingency, this (floor abatement project) is by far the largest item we have that has exceeded what we anticipated for the budget. It’ll basically take care of what we had allocated for contingency.”
He recommended that more funds be allocated toward the project by suspending contributions from the sales tax fund for debt service for a year, which would allow about $260,000 more for the project.
Floor abatement is scheduled to begin Monday, March 12.
Randy Littrell of Story Construction said contractors already have removed scoreboards, bleachers and backboards from the fieldhouse.
To prevent disruptions during the school day, work is only being done in the evenings.
The board also awarded a contract for renovations at George Washington Elementary to the lowest bidders: Bi-State Contracting, selective demolition; Frank Millard & Company, general work; Moore’s Floors, flooring finishes; Pauley & Sons, paints and coatings; and Mohrfeld Electric, electrical and communications work. Renovations will take place over the summer.
Rochleau said all bids came in under budget.
No comments were made during a public hearing regarding George Washington renovations.
In other business, the board:
Approved a three-year agreement with American Federation of State, County and Municipal Employees AFL-CIO Local 2005 (custodians, maintenance, bus drivers and food service workers). The contract includes salary increases of 2.5 percent in 2012-13; 2.25 percent in 2013-14; and 2 percent in 2014-15.
Approved a Talented and Gifted Acceleration Plan as presented by TAG instructor Diane Berner.
The plan allows students to advance in academic areas of strength, if they’re ready and motivated for the challenge.
Will request that the city replace stop lights at the Ninth and 10th street intersections on Timea Street next to Wells-Carey Elementary with four-way stop signs. The city had asked the district’s permission to remove the lights. Because Wells-Carey will continue to function as a bus stop after the school closes, the board wants traffic control in place.
Held the first readings of board policies regarding conflict of interest and written procedures for the monitoring of the tax-exempt status of bonds.
Approved an extra duty resignation from certified staff member Lisa Weis, George Washington lunchroom supervision, effective at the beginning of 2012-13.

A case study of mercury and methylmercury dynamics in a Hg-contaminated municipal wastewater…
From the issue entitled “Mercury as a Global Pollutant”
A study of total Hg (Hg) and methylmercury (MeHg) was performed in a 40 mgd capacity municipal sewage treatment plant in which elemental Hg was used as a seal in 3 trickling filter center columns. Each seal contains several hundred kg of Hg. The seals have leaked repeatedly over time, prompting the current remediation study and ongoing replacement of the Hg seals with mechanical seals. A mass balance conducted three times while the seals were in place showed that the plant acted as a net source of both Hg and MeHg during normal operation. The average amount of Hg released in sludge plus effluent was 157 g Hg and 0.4g MeHg/d. Of this total, 138 g Hg and 0.3 g MeHg were in excess of influent wastewater, and were contributed by the WTP itself. About 95% of the total Hg was released in sludge, with only 6 to 7 g/d released to the receiving water body. However, on average, about 70% of the MeHg leaving the plant was released to the river. Effluent MeHg concentrations were 4–6 ng/L. The plant components that acted as the major sources of both total and MeHg within the plant were the trickling filters (TFs). Metallic Hg accidentally lost from the center column seals has accumulated in the rock filter media and underbedding of the tricking filters. MeHg production across the TFs was positively related to the Hg concentration in each of the TFs. A substantial fraction of the total Hg but not of MeHg was lost to sludge in each settling step. About 50% of the remaining MeHg appeared to be degraded during the tertiary aeration step. The seals have leaked repeatedly over time, prompting the current remediation study and ongoing replacement of the Hg seals with mechanical seals.

Mercury-Added Products Found at Drinking Water & Wastewater Treatment Facilities
The Massachusetts Department of Environmental Protection (MassDEP) contracted with the Northeast Waste Management Officials’ Association (NEWMOA) and the New England Interstate Water Pollution Control Commission (NEIWPCC) to prepare a report on mercury containing devices likely to be found at drinking water and wastewater treatment facilities. The main purpose of this Report, entitled, Mercury-Added Products Found at Drinking Water & Wastewater Treatment Facilities is to support MassDEP outreach efforts during the upgrades of primary and secondary wastewater and drinking water treatment facilities under the American Recovery and Reinvestment Act (ARRA) and state revolving fund (SRF).
Mercury-added products may be found at drinking water, wastewater, and sewage treatment plants, as well as public water supply facilities, including pumping stations and distribution stations, (collectively referred to as “water treatment plants” throughout the rest of this Report). These products may be in use or stored at these facilities.
