The main case study is that of Dunsink Landfill in Finglas, County Dublin. Other landfills focused on are Nantygwyddon Landfill in Rhondda, Wales and Miron Quarry in Montreal, Quebec, Canada. This thesis examines all forms of continuous illness found in three areas near Dunsink Landfill, not just more serious illnesses such as cancers. These illnesses range from runny noses, coughs and colds to the more serious illnesses of cancers. Public perception is dealt with by examining two opposing viewpoints of landfills and why these viewpoints have been taken. The opinions of the residents, the North-West Area Manager for Dublin City Council and Dr. Eugene Boyle of the Health Service Executive (HSE) are also taken into account. A door-to-door survey o f three areas in Finglas was used in order to obtain the information needed for the study. This survey included questions relating to health, opinions and own knowledge.
