A recent analysis of Niue’s groundwater that tested for selected chemical and organic pollutants has found that the country’s water supply is very good and well within global standards.  

The study focused on all 16 boreholes used to pump Niue’s drinking water, three monitoring boreholes located on the island’s central, northern and southern areas and a borehole found on Vaiea farm.

Due to local concerns of pollution from pesticides like paraquat, groundwater was tested for traces of all pesticides used on the island. The study found that there was no contamination from pesticides with levels recorded well within the United States Drinking Water Standard.
