PCRWR Expert Cautions Against Assuming Ultra-Low TDS Water Is Healthier
Pakistan Council of Research in Water Resources official warns that removing too many minerals through Reverse Osmosis systems may not improve water quality.
A water quality expert from the Pakistan Council of Research in Water Resources (PCRWR) has cautioned against the growing perception among households that water with an extremely low Total Dissolved Solids (TDS) reading is automatically healthier, according to a report by the Associated Press of Pakistan (APP).
The expert noted that the increasing use of Reverse Osmosis (RO) filtration systems in homes has led many consumers to believe that stripping water of nearly all dissolved minerals results in superior drinking water, a notion the expert said is misleading.
According to the PCRWR expert cited by APP, unnecessarily removing minerals from drinking water through RO treatment does not necessarily equate to better quality, and consumers should not treat an ultra-low TDS concentration as a definitive marker of purity or health benefit.
The report did not specify particular TDS thresholds or additional technical guidance from PCRWR, but it underscored a broader caution from water quality experts urging consumers to reconsider assumptions about mineral content in treated drinking water.
PCRWR is Pakistan's national body responsible for research and guidance on water resources and water quality standards in the country.
