However, the Chip plants all clean the water as it leaves the plant, to the degree that it leaves much cleaner than it enters. It is all monitored as well both by the chip maker and the municipality. In the end, it is a very clean industry, given the steps taken. Home darkrooms in general dump their chemistry down the drain. No cleaning. Pro labs do a mixture of both... dependent on the local laws in place. Frank Filippone red735i@earthlink.net .............. my guess is chips and electronics create their own hazards while being made.
