Water Sanitation detection

[lightroses]

Hello to all! I'm just asking if it is possible to do a system like water sanitation detection for drinking water.

The logic is when the user deep the device into the water the system will recognize if the water is able to drink or not!

Any suggestions and advice. Thanks in advance

This has less to do with software development than it does with hardware. And yes, there exists hardware that can measure the quality of water. The software only comes in at the end to display the data in a friendly manner.
