Bonghwa County, North Gyeongsang Province, South Korea – Shocking revelations have emerged regarding the severely contaminated groundwater in the vicinity of the Youngpoong Seokpo Smelter, located in Bonghwa County, North Gyeongsang Province. Recent data indicates alarmingly high levels of heavy metals, including arsenic and cadmium, far exceeding safe drinking water standards. This grim discovery has designated the area as one of the most severely polluted groundwater regions nationwide, raising serious concerns about public health and environmental safety.

The alarming findings were brought to light through data submitted by the Ministry of Environment to Kim Tae-sun, a member of the Environment and Labor Committee of the National Assembly, representing the Democratic Party of Korea. The “2022 Groundwater Pollutant Detection Status” report revealed that groundwater contamination by heavy metals and other pollutants was detected in 51 local government units across the country. Critically, the report highlighted that the groundwater in numerous affected areas was deemed unsuitable even for industrial use, underscoring the severity of the pollution.

Further compounding the issue, a 2023 sample survey conducted by the National Institute of Environmental Research, encompassing 2,000 wells nationwide, found that a staggering 61.9% (1,237 cases) failed to meet the standards for potable water. The situation is particularly dire in Bonghwa County, where the Seokpo Smelter is situated. Out of 15 groundwater quality tests conducted in the area, arsenic levels were found to be in violation of safety standards in eight instances.

The Daegu Regional Environmental Office’s analysis of groundwater samples collected from 33 wells within its jurisdiction painted an even more disturbing picture. Cadmium concentrations were found to be up to 30,000 times higher than the industrial wastewater standard of 0.02 mg/ℓ, reaching levels between 0.28 and 753 mg/ℓ. The same investigation also identified instances of mercury, lead, and chromium exceeding permissible limits.

A 2022 survey by the Korea Environment Corporation corroborated these findings, revealing arsenic levels up to 0.283 mg/ℓ and fluoride levels up to 3.001 mg/ℓ in the groundwater of the Seokpo Township area, both surpassing regulatory limits. The presence of not only the active smelter but also abandoned mines in the vicinity is believed to contribute to this complex and severe contamination.

The neighboring Socheon Township has also been affected, with high concentrations of fluoride detected, prompting concerns about the safety of drinking water in the area. Worryingly, some locations in Socheon Township also exhibited arsenic levels exceeding safety standards. In response to the escalating crisis, the Ministry of Environment has designated the affected regions as groundwater contamination zones and has initiated detailed investigations and management projects.

The Youngpoong Seokpo Smelter has a history of environmental violations. In 2019, the smelter was caught illegally discharging wastewater and installing unauthorized pipelines, leading to a 58-day suspension of operations under the Water Environment Conservation Act. Despite this punitive measure, pollution concerns have persisted. Tragically, in late 2023, four workers suffered casualties, including fatalities, due to arsenic poisoning at the smelter, highlighting the severe health risks associated with the facility’s operations.

The repeated environmental breaches and the recent worker fatalities have intensified calls for the permanent closure or relocation of the Seokpo Smelter. In March, a public forum was held at the National Assembly, co-hosted by National Assembly members Kang Deuk-gu and Lim Mi-ae, both from the Democratic Party, to discuss the potential closure or relocation of the smelter and explore just transition measures for the affected community. The forum emphasized the urgent need for the formation of a government-led consultative body to address the complex issues surrounding the smelter.

Environmental advocacy groups, including the Korea Federation for Environmental Movements (KFEM) and the Nakdong River Network, have also amplified their demands. On April 18th, these organizations held a press conference in front of the National Assembly, urging major presidential candidates to include pledges for the smelter’s relocation, the implementation of a citizen oversight system, and the establishment of a government-level response task force in their election platforms. These groups argue that the long-standing pollution issue requires immediate and decisive action at the highest levels of government.

The groundwater contamination crisis extends beyond the Seokpo Smelter. Troubling instances of carcinogenic substances being detected near industrial complexes across South Korea have also come to light. In areas such as Iksan (North Jeolla Province), Bupyeong (Incheon), Gumi (North Gyeongsang Province), Sasang (Busan), and Songjeong-dong (Cheongju), levels of trichloroethylene (TCE) and tetrachloroethylene (PCE) have been found to exceed safety standards. Furthermore, a 2022 survey conducted by the Seoul Metropolitan Government Institute of Health and Environment on 140 discharged groundwater sites in Seoul revealed that 14 of these locations had per- and polyfluoroalkyl substances (PFAS) levels exceeding regulatory limits. These widespread contamination incidents underscore a systemic issue requiring national attention and robust regulatory oversight.

The health consequences of exposure to heavy metals like arsenic and cadmium are severe and well-documented. Chronic arsenic exposure can lead to various cancers (skin, bladder, lung), cardiovascular diseases, neurological problems, and developmental issues. Cadmium exposure is linked to kidney damage, bone disease (osteoporosis, osteomalacia), and an increased risk of lung cancer. The elevated levels of these toxins in the groundwater near the Seokpo Smelter pose a significant threat to the health and well-being of the local population, potentially leading to long-term health problems and a diminished quality of life.

The ecological impacts of such widespread groundwater contamination are equally concerning. Contaminated groundwater can seep into rivers, streams, and agricultural land, harming aquatic ecosystems, contaminating soil, and potentially entering the food chain. This can have cascading effects on biodiversity and agricultural productivity, further impacting the livelihoods and health of the community. The Nakdong River, a vital water source for a large part of southeastern South Korea, is particularly vulnerable to contamination from the Seokpo Smelter area, raising concerns about the broader regional impact.

The history of the Youngpoong Seokpo Smelter is marked by a long record of environmental controversies. Since its establishment in 1970, the zinc smelting plant has faced numerous accusations of polluting the surrounding environment, particularly the Nakdong River watershed. Residents and environmental groups have consistently raised concerns about the discharge of untreated wastewater, the leakage of heavy metals, and the overall impact of the smelter’s operations on the local ecosystem and public health. These historical issues provide context for the current groundwater contamination crisis, suggesting a long-term failure in environmental management and regulatory oversight.

The economic implications of the groundwater contamination are also significant. The devaluation of land, the potential decline in agricultural output, and the costs associated with healthcare and environmental remediation can have a substantial impact on the local economy. Furthermore, the loss of trust in local industries and the potential for social unrest can create additional economic challenges for the region. A just transition plan, as advocated by environmental groups and discussed at the National Assembly forum, would need to address these economic consequences and provide support for affected workers and the broader community in the event of the smelter’s closure or relocation.

In conclusion, the severe groundwater contamination near the Youngpoong Seokpo Smelter represents a critical environmental and public health crisis. The alarmingly high levels of arsenic and cadmium, coupled with the smelter’s history of environmental violations and the tragic worker fatalities, underscore the urgent need for decisive action. The calls for the smelter’s closure or relocation, along with demands for enhanced government oversight and a just transition plan, reflect the deep concern and frustration of the local community and environmental advocates. As Representative Kim Tae-sun emphasized, “Groundwater is a vital resource that affects not only public health but also agriculture and the entire ecosystem. The arsenic contamination near the Seokpo Smelter requires continuous monitoring and investigation, and prompt government action is necessary to address this critical issue and prevent further harm.” The situation demands immediate and comprehensive measures to protect the health of the residents, remediate the contaminated environment, and prevent similar industrial pollution incidents in the future. The long-term well-being of the community and the integrity of the environment depend on swift and effective intervention.
