Do you have updated technique for micro pollutants removal from water?

During the Network's last webinar “Water quality testing in action: Making your testing program work in the real world” there were some questions to our panelist Dr. Anna Murray that couldn't been answered because of time constraints. She answered them in written for us to share with all of you. ¡Thank you Anna!

Question: Do you have updated technique for micro pollutants removal from water?

  • One thing is clear with water quality testing: the number of parameters you can test is endless! The importance of prioritizing them should be determined based on their relative risk. In many low and middle income settings, the highest health risk remains diarrheal disease, which stems from microbiological contamination of water supplies. After this, there are chemical parameters like fluoride, arsenic, nitrates, lead, and other heavy metals. There are a host of emerging contaminants, microplastics, etc etc, that are difficult to test, and aren’t currently regulated even in municipal water systems in high-income countries. This isn’t to say they aren’t important, but the practical risks of these may be cancers after large volumes are consumed over a long period of time. Microbiological contamination, however, can lead to immediate health impacts that we know are detrimental to children and immunocompromised people.
  • In terms of micropollutant removal, this is outside of my expertise.
