Acrylamide in water

15. Why is polyacrylamide used in the treatment of drinking-water?

Polyacrylamide is used as a one of a variety of cleaning agents, combining with solid material making it easier to filter/remove unwanted substances from water. There are only very low levels of acrylamide in polyacrylamide.

16. Is there a guideline stating the maximum limit for acrylamide in water?

According to the WHO Guidelines for Drinking-water Quality, the guideline value (the concentration representing the tolerable risk to the health of the consumer over a lifetime of consumption) is 0.5 micrograms per litre in drinking-water. Concentrations in drinking-water can be controlled by product and dose specification. The European Union’s legal limit for drinking-water is 0.1 micrograms per litre of water. Some countries, like the United States and Japan, have regulations on treatment techniques, rather than a water quality standard value for acrylamide.
