Water with biologic agents

Special Considerations Intentional Contamination of Food or Water with Biologic Agents...

I heard of a case where the ultrapure water distribution system became contaminated with biological agents ( wee beasties ). The maintenance people knew how to solve the problem - they dumped pool chlorine in the water feed. It blew up the ion exchange columns. In another case, the top of the storage tank was left uncovered and seagulls left their waste in the storage tank. 

Synthetic examples include the poly(meth)acrylates used as flocculating agents for water purification. Biological examples are the proteins, nucleic acids, and pectins. Chemically modified biopolymers of this class are carboxymethyl cellulose and the lignin sulfonates. Polyelectrolytes with cationic and anionic substituents in the same macromolecule are called polyampholytes. 

Potassium Hydroxide (caustic potash) will work on certain chemicals and biological agents. Remarks under sodium hydroxide apply across the board to potassium hydroxide. Ammonia or Ammonium Hydroxide (household ammonia) can be used to decontaminate G nerve agents but takes longer than sodium hydroxide or potassium hydroxide. SCBA or a special purpose mask is required when working with this product. Ammonium hydroxide needs no further mixing it is a water solution of ammonia.
