DAEJEON, South Korea – The Daejeon Institute of Health and Environment (DIHE) is set to commence a comprehensive survey of 85 areas suspected of soil contamination starting May 22nd. This proactive measure aims to safeguard public health and preserve the local environment. The survey will focus on sites with a high likelihood of contamination, including industrial complexes, factories, gas stations, and children's playgrounds.

The targeted areas include 13 locations that, last year, showed heavy metal and fluorine concentrations exceeding 70% of the soil contamination warning standards. This year's survey will also prioritize newly designated land development zones and aging gas stations, identified as key management targets.

To ensure the integrity of the sampling process, the DIHE provided advance training on May 19th to district officials responsible for collecting samples. Both topsoil and subsoil samples will be analyzed for 23 potential contaminants, including heavy metals and volatile organic compounds (VOCs), with a focus on those most likely to be present based on the site's history and current use.

Should the survey reveal any areas exceeding the established warning standards, the city and district authorities will issue orders for detailed investigations and mandate soil purification and restoration to those responsible for the contamination.

"Contaminated soil poses significant risks to citizen health and can adversely affect water quality and agricultural products, while restoration efforts incur substantial costs," stated Shin Yong-hyun, Director of the DIHE. "Through regular surveys, we aim to proactively prevent soil contamination."

This soil contamination survey is part of an annual nationwide initiative spearheaded by the Ministry of Environment. Last year, all 85 surveyed sites (110 cases) in Daejeon were found to be within acceptable limits, receiving a "suitable" rating.
