Can you Define Quality of drinking water ? what is the composition of particals?
It is required standards of drinking water Qualities. It is easy to me send chart or tables relavent.
Potable water quality is guided by either WHO or BIS specifications in India. 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.

EPA sets standards in the USA.
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.
