Particles in drinking water is measured by a "turbidimeter". Usually these are fine clay particles with a neutral charge that are hard to congeal or flocculate together to form a larger particle for settling, but small enough to penetrate and discharge from a sand filter. There is an exact definition of the term "quality" that I have long forgotten. It is basically water having a neutral taste and odor, colorless in nature, and having no adverse action in human consumption.<br><b>References : </b><br> EPA sets standards in the USA.

Every country has their own specification differing from each other a little bit. Main requirement for composition are : TDS EQUAL OR LESS THAN 500 PPM. pH = 7.5 . TURBIDITY = LESS THAN 5 ppm. CHLORIDES/ sulphates = LESS THAN OR EQUAL TO 250 PPM. COLIFORM BACTERIA count = OR LESS THAN 100. ODOUR OR COLOUR = NIL. RESIDUAL CHLORINE = 0.2 ppm.<br><b>References : </b><br>BIS specification Potable water quality is guided by either WHO or BIS specifications in India.
