Hercules Brunswick facility, circa 1960.
As a major economic force, Hercules grew along with Brunswick. The Brunswick facility, located on Glynn Avenue near the causeway bridge, had a long history of manufacturing operations that spanned more than a century. With the exception of the Great Depression years, it operated since 1911, using pine tree stumps to make rosin and other products.
Since the advent of state and federal environmental regulations, much has been accomplished to address the environmental legacy of these historical operations.
In 2023, a fire caused the permanent shut down of the facility. In 2025, demolition activities on the physical structures of the facility were completed. Remediation at the site did not stop and is still continuing with a focus toward reuse of the property.
100+ Years of History
Generations of Brunswick people worked at the Brunswick facility when it was operated by Hercules, and then by Pinova from 2010 through 2023. Even after its operations ceased, Hercules has been conducting environmental remediation and restoration at three sites in Brunswick. A timeline summarizing the history of operations and remediation at these three sites is below.

Sediment removed in Terry Creek
Lining of the N-Street Ditch

1984 | The |
1990s | Hercules continued investigation and remediation at the plant. It removed and remediated an equalization basin and above-ground storage tanks in the northern portion of the facility and conducted biological treatment in the area to prevent contaminants from being carried in groundwater. |
1993 | EPA approved Hercules' remediation plan for the 009 Landfill. |
1995 - 2009 | Hercules installed and operated a groundwater pump and treat system to extract and treat groundwater from the northern portion of the Brunswick facility. |

2000s | Hercules continued its investigation to identify areas to be remediated. Hundreds of acres, above and below ground, were sampled and studied extensively. |
2001 | The state conducted fish tissue sampling showing improvement in fish tissue quality after Hercules’ remediation of the outfall ditch and creeks. |
2005 | Hercules resumed the state's fish tissue sampling, confirming continued improvements in fish tissue quality. |
2005 | Hercules leases a portion of the 009 Landfill cap to be used by the neighboring auto dealer as a part of its car lot. An asphalt cap is built on top of the exisitng landfill cap. |
2007 | The state relaxed fish consumption advisories after remediation activities in the outfall ditch and the adjacent creeks resulted in improvements. |
2008 - 2010 | Hercules remediated the former toxaphene production plant and the N-Street ditch: demolishing the plant, excavating 47,000 tons of soil from the plant and the ditch, backfilling the plant area, and relining the ditch. |
2010 | Pinova purchased the operational portions of the Brunswick facility. |
2010s | Hercules further investigated groundwater conditions, assessed potential risks, and planned additional remediation work. |
