People  on  globe  are  below  tremendous  threat  thanks  to  unsought  changes  within  the  physical, 
chemical  &  biological  characteristics  of  air,  water  &  soil.  Thanks  to  inflated  population, 
urbanization, manufacture, use of fertilizers water is extremely impure with completely different 
harmful  contaminants  Natural  water  resources  are  being  contaminated  thanks  to  weathering  of 
rocks & natural process of soil; mining process etc. it's necessary that quality of potable ought to 
be  checked  at  regular  amount  to  stop  numerous  waterborne  diseases.  In  gift  analysis  physico-
chemical  parameter  of  potable  comparable  to  color,  pH,  hardness,  TDS,  residual  Cl,  dissolved 
atomic number 8, electrical conduction, Free greenhouse emission are analyzed. potable quality 
of  10  villages  of  Alsisar  district  Jhunjhunu,  Rajasthan  was  analyzed  to  spot  the  character  and 
quality of water .The potable samples were collected in clean synthetic resin one cubic decimeter 
cans & subjected for analysis in laboratory.  The most objective of the current paper is to aware 
folks of involved space concerning the water quality & involved health hazards.
