I'm trying to create an array of sensors to detect chlorine, impurities, chemicals and other contaminants in the water.
So far i found
-ph sensor (requires calibration),
-turbidity sensor (the optical path of a turbidity meter needs to be kept clean and requires routine maintenance)
-Oxidation Reduction Potential sensor (can lead to misrepresentative readings)
Is there any cheap compact sensor that is able to determinate whether your water is safe to drink or not?

I guess the cheapest sensor for this type of information is an aquarium with trouts. Put a camera in front and check if the trouts are still moving.
I believe it's not possible to build an electrical sensor that is able to qualify water as safe to drink. Simply because there are so many different poison substances out there, you cannot sense them all. I guess the deciding part in such a sensor must be biological, electrical sensors cannot distinguish if a bacterium is poisoning humans or not.

Basically no.
This might just explain why you see no such devices for sale.
Call up your local water testing department and ask what it costs for a determination of water potability.
