  • According to foster the Pusan Public Park in site of Camp Hialeah, we recorded about building which has historical and cultural meaning. This study is to organize the resource about properties of material and structural properties of Barracks of Japanese army and Quonset hut which was constructed from 1940's to 1950's in Camp Hialeah.

  • Batch experiments using indigenous and commercialized adventive microorganisms were performed to investigate the feasibility of the biodegradation process for the diesel contaminated soil, which was taken in US Military Camp 'Hialeah', Korea. TPH concentration of the soil was determined as 3,819 mg/kg. Four indigenous microorganisms having high TPH degradation activity were isolated from the soil and by 16S rRNA gene sequence analysis, they were identified as Arthrobacter sp., Burkholderia sp., Cupriavidus sp. and Bacillus sp.. Two kinds of commercialized solutions cultured with adventive microorganisms were also used for the experiments. Various biodegradation conditions such as the amount of microorganism, water content and the temperature were applied to decide the optimal bioavailability condition in the experiments. In the case of soils without additional microorganisms (on the natural attenuation condition), 35% of initial TPH was removed from the soil by inhabitant microorganisms in soil for 30 days. When the commercialized microorganism cultured solutions were added into the soil, their average TPH removal efficiencies were 64%, and 54%, respectively, which were higher than that without additional microorganisms. When indigenous microorganisms isolated from the contaminated soil were added into the soil, TPH removal efficiency increased up to 95% (for Bacillus sp.). According to the calculation of the average biodegradation rates for Bacillus sp., the remediation goal (87% of the removal efficiency: 500 mg/kg) for the soil would reach within 24 days. Results suggested that TPH removal efficiency of biodegradation by injecting indigenous microorganisms is better than those by injecting commercialized adventive microorganisms and only by using the natural attenuation.
