What are the automatic water quality analyzers available out there? If toxic wastes are dumped into rivers, how can the automatic water quality analyzers detect fast enough to alert the SCADA systems?
An internet search should fill your requirements better than I can.
However, what you need to do is determine what it is that you are looking for and at what level (PPM) or (%) from there start your search. Then remember that sensors will need periodic calibration and will likely assist but not fulfill government or insurance reporting requirements.
Also, please do not let them lull your company into a false sense of security. Proper equipment, training and procedures are your first line of defense with prevention being the ultimate goal.
