All eight officially designated beaches in the region have passed environmental inspections for both water and sand quality, confirming they meet national safety standards ahead of the full summer vacation season.
According to a joint survey conducted by the National Institute of Environmental Research and the city, the levels of Enterococcus and E. coli, key indicators of waterborne illness, were well below the safety thresholds at each beach. The presence of heavy metals such as cadmium, arsenic, and lead in beach sand was also found to be within safe limits, and substances like mercury and hexavalent chromium were undetectable at all sites.
The eight beaches included in the inspection are Haeundae, Songjeong, Dadaepo (east and west), Songdo, Gwangalli, Ilgwang, and Imrang.
Water samples taken from these locations in June showed values ranging from 0 to 37 MPN/100mL for Enterococcus and 0 to 228 MPN/100mL for E. coli—both within legally allowed limits.
Sand quality results showed cadmium levels between 0.77 and 2.27 mg/kg, arsenic between 5.52 and 11.12 mg/kg, and lead between 12.6 and 24.9 mg/kg, all under the management standards for beach safety.
The city cautioned, however, that heavy rainfall may temporarily affect beach water quality and advised the public to avoid swimming immediately after rain.
Detailed results are available through the Busan City Environmental Information website (busan.go.kr/ihe) and the Marine Environment Information Portal (www.meis.go.kr).
