Many individuals are becoming more health-conscious these days and are therefore querying how safe their tap water is to drink and just what is actually contains that could be harmful to their health.
A YouGov survey done in 2015 on behalf of the Consumer Council for Water, revealed that only around 39% of people felt that the tap-water in the UK is good quality drinking water.
While many individuals often wonder what exactly is in their tap-water, this is not that easy to discover as tap water does not come with packaging that lists its contents. The only way to actually find this out is to know who your water-supplier is and check their company website for information about their water quality.
Most water companies will provide details regarding the hardness and fluoridation level of the water they are supplying you and many of them also offer the option to view a full quality report. Technical reports can be hard to decipher and understand though, so Water UK has created a brief set of guidelines to help you.
Water Quality: Do not be confused about all the parameters and substances regularly analysed; skip down to the final paragraph which should show the percentage of samples that failed to meet the required standards [fusion_builder_container hundred_percent=”yes” overflow=”visible”][fusion_builder_row][fusion_builder_column type=”1_1″ background_position=”left top” background_color=”” border_size=”” border_color=”” border_style=”solid” spacing=”yes” background_image=”” background_repeat=”no-repeat” padding=”” margin_top=”0px” margin_bottom=”0px” class=”” id=”” animation_type=”” animation_speed=”0.3″ animation_direction=”left” hide_on_mobile=”no” center_content=”no” min_height=”none”][usually shown as samples contravening prescribed concentration or value (PCV)].
Mineral Content: you are unlikely to encounter water in its pure form, as there is generally many minerals present in water. Water that is suitable for everyday use must meet a defined limit for the total mineral content (expressed in the quality report as conductivity). Water with a conductivity of up to 800 μS/cm, or about 500mg/l is best for human consumption.
Certain minerals have the potential to be present in more notable amounts, and are of particular interest as per this list from the World Health Organisation (WHO):
- Calcium – important in bone health and possibly cardiovascular health
- Magnesium – important in bone and cardiovascular health
- Sodium – an important extracellular electrolyte, lost under conditions of excess sweat
- Selenium – important in general antioxidant function and in the immune system
- Potassium – important for various biochemical effects (not usually found in natural drinking waters at significant levels).
The maximum allowable mineral conductivity is set at 2500 μS/cm.
