Aura of the Past: The Rehabilitation of ‘Puhipuhi Mercury Mine’

<p>Through the development of the case site ‘Puhipuhi Mercury Mines’ this design led thesis presents the fusion of ruins with new design, aiming to rehabilitate the site and its history. The delicate nature of the site’s past and its remaining relics present the potential to curate a history. The method of integrating old and new design to reestablish value is explored. Puhipuhi mine has a negative reputation today. Documented memories focus on the mine's industrial downfall and remaining areas of contamination. This has dampened its prospects. The case site has remained dormant since its closure in 1945 (Butcher). With political controversy surrounding the site, and with natural growth dominating the remains, it has become virtually inaccessible. The challenge presented by the characteristics of the site poses the following research question: ‘How can the fusion of old and new architecture add value to a forgotten and contaminated historic site as a means to preserve its history and rehabilitate it for current day use?’ Abandoned elements which lay dormant in our landscape have the opportunity to be valued as iconic elements in New Zealand's history, yet we are hesitant to seek appreciation for the narratives of their past and as a result we are presented with the possibility of historic loss. The site's processing plant presents a need to preserve its architectural heritage and document its history as a means to re mediate the damage of contamination and the devalue that has generated since the closure of the program. Attention is needed to establish it as the beautiful landscape, intriguing remains and educational opportunity that it has the potential to become. Through the establishment of age, historic and use values, new programmes are constructed: a toxicity museum and laboratory.</p>

Assessment of Trace Elements in Soils and Sediments in the Abandoned Mercury Mine Site in Puerto Princesa City, Philippines

An abandoned mercury mine area in Puerto Princesa City, which was previously operated by Palawan Quicksilver Mines, Inc. (PQMI) from 1953 to 1976, is known for its unrehabilitated open-pit of mercury-rich rocks and exposed mine waste calcine stockpiles in the vicinity. In order to establish an understanding on the geology of the abandoned mercury mine deposit and to obtain clues in determining the possible metal pollutants in the area, measurement of trace element concentrations of soil and sediments collected from the PQMI vicinity were conducted. Soil and sediment samples were analyzed for heavy metals, rare-earth elements and naturally occurring radioactive elements and determined its contamination factor as part of risk assessment. Analytical results showed that aside from mercury, several heavy metals (nickel, chromium, manganese) were found to be anomalous due to the geology of the area. Statistical analyses show that chromium, nickel and antimony present the highest contamination factor among the sampling groups. Mercury is found to have negative bias with higher rare earth elements concentration but positively correlated with arsenic, antimony, and thallium. In general, there is low concentration of rare earth elements (except for scandium) in comparison with its respective average crustal concentration. Due to the nature of geology in the area, naturally occurring radioactive elements influence is also minimal. The results of this study, especially on the assessment of soil and sediment pollutants, are recommended as guidance to its mine rehabilitation.
