DHEC‘s Bureau of Land and Waste Management (BLWM) staff joined the United States Environmental Protection Agency (EPA) Region 4 to celebrate the successful ecological revitalization of the Henry’s Knob Superfund Site on May 1. The EPA awarded ABB, Inc. (ABB) their Excellence in Site Reuse Award for ABB’s efforts to restore the former mine site to a natural habitat. Region 4 established the “Excellence in Site Reuse” award to recognize those who have supported the Superfund Redevelopment Initiative through outstanding efforts when redeveloping a Superfund site.

Located in Clover, SC, the Henry’s Knob site was operated as an open pit kyanite mine from 1947 through 1965. Kyanite is a mineral used in refractory, ceramic and porcelain products. Mined ore-grade rock was ground up and floated to separate kyanite from other minerals. The waste rock and tailings were dewatered in ponds and piles and left onsite. Where iron sulfide minerals in the waste are exposed to water and oxygen, acid mine drainage occurs and can impact surface water and groundwater. These acidic conditions can mobilize metals. At the Henry’s Knob site, these conditions led to over 37 acres of unvegetated soils vulnerable to erosion, acidic water in the mine pit and surface drainages, and contamination of groundwater impacting nearby private water supply wells.

In the 1990s, ABB acquired the company that operated the mine and the environmental legacy associated with the property. Through an adaptive management approach, ABB and EPA worked with former BLWM project managers Chuck Williams and Kayse Jarman and current project managers Joel Padgett and Sara MacDonald to identify a cleanup approach to stabilize the impoundment dams, mitigate on-going erosion of the mine tailings through revegetation and stormwater control, and minimize impact to groundwater and nearby surface water. Beginning with a successful pilot study in 2013 and completed in December 2017, mine tailings in four areas of concern were successfully revegetated. HenryKnob-before-afterTraditionally, “dig and haul” has been used to remove tailings from mine sites.  However, amending the soils in place leaves a lower carbon footprint and literally transformed these barren, low-pH soils into green fields. In other efforts to “green” the cleanup and provide economic benefit to the local community, ABB’s contractor locally sourced hay and organic compost to amend the soil, riprap to stabilize channels and dam faces, and native seeds to increase pollinator habitat.

This interim remedy approach has not only turned the site into an attractive ecological habitat and renewed the view for Henry’s Knob’s neighbors but also has served as an important first step in improving surface water and groundwater in the area.  BLWM will continue to partner with EPA and ABB as the project moves into the next phase of cleanup.

From Other Blogs: Handwashing, mold after a flood, safer food choices & more

A collection of health and environmental posts from other governmental blogs.

Protect yourself and wash your hands the right way

Hand washing is the number one way to help prevent the spread of germs and diarrhea-related illnesses. As flu season approaches, it is vital that we make a habit of washing our hands frequently throughout the day. — From Flourish, Palmetto Health’s blog

Tips on Cleaning Mold after a Flood

Returning to your home after a flood is a big part of getting your life back to normal. But you may be facing a new challenge: mold. What can you do to get rid of it?  How do you get the mold out of your home and stay safe at the same time? CDC has investigated floods, mold, and cleanup, and offers practical tips for homeowners and others on how to safely and efficiently remove mold from the home. — From the Centers for Disease Control and Prevention’s (CDC) Your Health — Your Environment blog

Help Your Patients Make Safer Food Choices

Every year, an estimated 1 in 6 Americans (or 48 million people) get sick, 128,000 are hospitalized, and 3,000 die of foodborne diseases. Salmonella and Campylobacter, two of the many types of bacteria that are commonly transmitted through food, can cause antibiotic-resistant infections.

As physicians, we can help patients protect themselves against foodborne illness by talking with them about their risk. — From the CDC’s Safe Healthcare blog

Carbon Monoxide (CO) Poisoning Prevention

Every year, at least 430 people die in the U. S. from accidental CO poisoning. Approximately 50,000 people in the U.S. visit the emergency department each year due to accidental CO poisoning. There are steps you can take to help protect yourself and your household from CO poisoning. Change the batteries in your CO detector every six months. If you don’t have a battery-powered or battery back-up CO detector, buy one soon. — From the CDC’s Your Health — Your Environment blog

DHEC in the News: Flu, recycling e-waste, using oysters to protect the environment

Here’s a look at health and environmental news from around South Carolina.

Taking preventative actions vital to staying clear of the flu

Cover your mouths, because flu season in South Carolina is underway.

The S.C. Department of Health and Environmental Control has released data saying for the week of Dec. 3 to 9, there were 24 lab-confirmed cases of flu and 893 rapid detection cases reported by clinical labs in South Carolina.

Keep Aiken Green: Know how to recycle e-waste in Aiken

After the holidays, once new televisions, new PS4s, new Xbox Ones, new computers, new sound systems and more settle in, the old ones tend to be done away with.

But where those unwanted electronics actually go, according to the state health and environment department, is of utmost importance.

Old Oysters Put to New Use at SRS for cleanup innovation

A member of the mollusk family could be the key to controlling the level of zinc in storm water runoff at Savannah River Site.

Savannah River Nuclear Solutions, the management and operations contractor for SRS, is among a small number of U.S. companies and utilities experimenting with oyster shells. They’ve found the shells naturally absorb zinc and copper from water, often reducing concentrations to acceptable levels.
