House of Commons Environmental Audit Committee was satisfied that water companies were doing enough to prevent ill effects of excess nitrates to humans by investing substantial sums in water treatment and blending plants. However the committee believed that costs would continue to rise for water companies if nitrate (and other chemical) pollution from agricultural sources continue to go unchecked. There was concern that health impacts of nitrates may become an issue in the future, or that water companies would have to pass the rising cost of treatment onto consumers.
In many European countries, legislation requires bottled water brands to clearly state nitrate levels on the label.
The maximum level recommended for babies and pregnant women is 10 mg/L, which is 20% of the maximum contaminant level (MCL*) recommended for adults.
