Actually, in the US, the EPA has strict mandates limiting public water supplies to a maximum of 10ppm of nitrates. Any public drinking water supply (not well) with nitrates higher than this are in violation of federal law. Anything higher than this also poses a signifigant health risk, particularly to infants, pregnant women, the elderly and those with compromised immune systems. I dont know what the regulations are in respect to drinking water supplies in other countries, so I dont know if this applies in this case.
