Asbestos contamination in the South Pacific originates mainly from construction products containing asbestos (SPREP, 2011). In Rarotonga, asbestos contamination in the soil surrounding two schools examined (Nikao Maori and Avatea) is believed to have originated from the Super Six roofing product that previously covered all existing classrooms on the site. This type of roofing becomes brittle and susceptible to increased weathering as the product ages. The weathering process from the sun, wind and rain releases the asbestos fibres into the environment (Bowler, 2014). The roofing has only recently been replaced with corrugated iron. The aim of this research was to identify remedial solutions for the removal and disposal of contaminated soil around the schools and for the future earthworks in Rarotonga. Four potential solutions were identified including: i. Capping the contaminated material on-site; i i . Removal and disposal of the contaminated material to local landfill; iii. Removal and disposal of the contaminated material internationally; iv. Removal and disposal of the contaminated material at sea. Solutions considered the feasibility of each option (both in the short and long-term), minimising impact on the residents and the workers exposed, reducing environmental impact and assessing the financial implications for each option
