Loren Schmidt saw the backhoe digging in a gravel-less part of a county gravel pit and wondered what was up. He became more curious when he saw truck after truck heading for the site. Then he detected an offensive odor.
When he got a look at what was going on, he was appalled. The county was dumping some smelly material into a 15-foot deep trench that appeared to have reached the groundwater.
All of this sounds worse than it really is, but even the sanitized version does not sit well with residents of the town of Bloomer, who met with DNR and county officials Tuesday.
Loren Brumberg and David Lundberg of the DNR’s waste management department told the 19 people gathered that the material was mostly soil mixed with animal waste and was not toxic, and the water in the trench did not come from the water table that fed their wells.
Still, resident Jean Turner said the bottom line was that the group wanted the material dug up and removed. That is not likely to happen any time soon, but County Administrator Bill Reynolds was agreeable to testing the residents’ wells to give them some peace of mind.
According to Brumberg, the story started in 1936, when a rendering plant was opened on a site just northeast of Chippewa Falls. It operated until 2002.
The county took the property for back taxes, and inherited a problem, including petroleum storage tanks, various toxic compounds and contaminated soils. The county received DNR grants for assessment and clean-up.
“They basically cleaned up the site, took care of all the contamination, taking care of all the waste materials,” Brumberg said.
The county then put the property on the market for industrial development and a drywall company bought it with plans to put in a $1.4 million distribution center.
During site development work, another problem was found. An area was discovered in which animal wastes and some crushed steel barrels had been buried.
The owner tried to haul the material to a landfill, but it became cost prohibitive. He was ready to back out of his project.
That’s when county economic development and DNR officials quickly got together, and within the space of a few days in late October came up with a plan to bury the waste at the gravel pit, which had been used at one time to dispose of road-killed deer.
Lundberg said the DNR was fine with leaving the material where it was, as tests showed it was not toxic nor a threat to groundwater. However, the owner wanted it removed at reasonable cost. And the DNR granted a permit for disposal at the gravel pit site, which led to the scene Schmidt witnessed.
The crushed barrels, which Brumberg said once held cooking oils, were hauled away for recycling. The other material was a mixture of mostly soil and decaying organic material from animals.
Neighbors protested, but after a meeting with DNR officials at the site, the situation quieted down and the project was finished. Tuesday’s meeting made clear residents were not satisfied.
Brumberg explained that the permit required the material to be at least 10 feet over the water table. He said the water in the trench leached from the side of the trench. He described it as water that soaked in at the surface, hit a layer of impermeable material and sort of pooled underground until it came out into the trench and pooled at the bottom of it.
That it was still above the water table from which wells draw water is seen by the level of a nearby pond created by the gravel pit and the depth of area wells, Brumberg said.
He also explained the ground has the ability to clean up bacterial contamination in the material, the same way it takes care of septic system drain fields and manure spread on fields.
Still, residents envisioned the water leaching into the buried materials, then down into the groundwater.
“Everything’s going to leach right into our drinking water,” said Eugene Kerckhove.
And if it wasn’t any worse than manure, why couldn’t it be handled in the same way, he asked.
“Why can’t the material just be spread out on the land and let the rain take care of it?” Kerckhove asked.
Brumberg said that would have worked, too, and might have been preferable.
Bloomer Town Chairman Vern Kellen complained that the project violated a town ordinance that prohibited the spreading of waste in the township that did not come from the township.
The DNR officials acknowledged that the town should have been notified, but were unsure if the ordinance applied.
Removal of the material would be expensive, as would setting up monitoring wells around the site to test any effect on groundwater. The offer to test residential wells to ensure the water was safe was the only solution that appears to be moving forward.
However, County Board member Paul Michels of Bloomer has a suggestion that received wide support. He noted that the gravel pit, or at least part of it, is near the end of its useful life, which means a closure plan will be implemented. Since closure involves earth moving, it could include a digging up of the burial site.
That plan may be for another day. For now, the materials remain buried in the town of Bloomer.
