Classification: CPC B  G  C | IPC B  C  G

Claim 0:
1. A water contaminant detection system, comprising:
a wastewater input in fluid communication with a waste outlet of a water treatment module, the water treatment module receiving a feed water stream;
a contaminant sensor configured to measure a concentration of a contaminant in a wastewater stream received from the waste outlet;
a water quality sensor module configured to measure a water quality parameter of the wastewater stream; and
a processor programmed to:
receive a measured concentration of the contaminant in the wastewater stream from the contaminant sensor;
receive a water quality parameter from the water quality sensor module;
obtain a predetermined efficiency value for the water treatment module; and
determine a concentration of the contaminant in the feed water stream based on the measured concentration of the contaminant in the wastewater stream, the water quality parameter, and the predetermined efficiency value.
