Neutralizing pH
I am our facility’s environmental, health and safety manager. Periodically, we have very high-pH wastewaters that cause the pH within the cyanide oxidation step to be well above our desired upper limit of 11.

I am very concerned about the release of hydrogen cyanide if something goes wrong and the system accidentally drives the pH well below 7. Are there any safer acid substitutes?

How do I better document whether or not I need to report for lead?
