Alkaline discharges from cement dust kiln piles, from the site of the former Penn Dixie cement plant, pose a serious health risk to humans and animals on or near the affected areas, with dangerous pH levels as high as 13.0, similar to a very strong bleach. The Michigan Department of Community Health considers pH levels of this magnitude to be a direct contact and public health hazard.
Recent sampling has confirmed that in addition to elevated pH, the leachate from cement kiln dust also contains other dangerous chemicals, including mercury and arsenic.
“We have been working with the EPA to facilitate a solution to the exposure issues revolving around the leachate discharges without compromising the ability to monitor the effectiveness of leachate removal activities,” said Scott Kendzierski, Director of Environmental Health Services. “It is a very complicated problem which requires immediate action on the beach, as well as a well thought out plan for addressing the source of the leachate.”
According to Kendzierski, EPA's Emergency Response Program staff recently issued a written “notice of potential liability” to potentially responsible parties, including owners, previous owners, and operators of the former Penn Dixie quarry. Within the notice, the EPA outlined a strategy to conduct emergency response activities and removal of leachate to prevent discharges of contaminants to Little Traverse Bay. In addition, the notice provided a requirement to restrict access to the affected areas by erecting fences, posting signs, and providing security of the shoreline. The shoreline is currently accessible by residents and employees of Bay Harbor, and from Lake Michigan by boaters and other recreational watercraft.
“We are concerned about the unsuspecting public, such as visitors to Bay Harbor,” said Kendzierski, “and are partnering with other governmental agencies and interested parties to protect the public and help direct the management of impacts to the environment.”
The Northwest Michigan Community Health Agency is the local health department serving Antrim, Charlevoix, Emmet, and Otsego Counties. Its staff is dedicated to preventing disease and injury and promoting healthy communities.
