Social deprivation and the public health risks of community drinking water supplies in New Zealand.
STUDY OBJECTIVE Quantitative evidence linking environmental exposures and social status at sub-national scales is surprisingly limited. This study investigated the public health risks associated with community water supplies in relation to social status in New Zealand. DESIGN An ecological study using a Geographic Information System (GIS) to compare the grade of community water supplies with ...
متن کاملThe cost-effectiveness of fluoridating water supplies in New Zealand.
OBJECTIVE Tooth decay has been substantially reduced in New Zealand, and the difference in caries rates between fluoridated and non-fluoridated areas has narrowed. We investigated whether it is cost-effective to fluoridate water supplies that are now non-fluoridated. METHODS The net cost of fluoridation was based on the cost of fluoridating a water supply minus the averted costs of treating d...
متن کاملMycobacterium lentiflavum in Drinking Water Supplies, Australia
Mycobacterium lentiflavum, a slow-growing nontuberculous mycobacterium, is a rare cause of human disease. It has been isolated from environmental samples worldwide. To assess the clinical significance of M. lentiflavum isolates reported to the Queensland Tuberculosis Control Centre, Australia, during 2001-2008, we explored the genotypic similarity and geographic relationship between isolates fr...
متن کاملValuing the subsurface pathogen treatment barrier in water recycling via aquifers for drinking supplies.
A quantitative microbial risk assessment (QMRA) was performed at four managed aquifer recharge (MAR) sites (Australia, South Africa, Belgium, Mexico) where reclaimed wastewater and stormwater is recycled via aquifers for drinking water supplies, using the same risk-based approach that is used for public water supplies. For each of the sites, the aquifer treatment barrier was assessed for its lo...
متن کاملDrinking water, ecology, and gastroenteritis in New Zealand
New Zealand has good quality drinking water derived from thousands of streams, rivers, lakes and aquifers fed by regular rainfalls ranging from 400 to 11 000 mm year". These waters are treated variously to provide over 80% of 3.6 million inhabitants with satisfactory drinking water. By international standards, New Zealand nevertheless has high incidence rates of potentially waterborne diseases ...
