Drinking water treatment tools are used to track the chlorine content of drinking water in households. The test tool is a NFC-enabled mobile phone. The NRC is responsible for providing health workers with 50 Nokia 6212 NFC phones; UPM RFID is responsible for providing UPM BullsEye NFC tags with built-in NXP Mifare Ultralight chips. Joseph "Jofish" Kaye is a senior research scientist at NRC. David Holstius is a student of the Department of Public Health at the University of California, Berkeley, and a Ph.D. student at the University. The Ph.D. student is also responsible for developing applications for mobile phones.
Most rural homes in Haiti have a water treatment tool, a 19-litre plastic bucket with lids and faucets. A bucket with an RFID tag is used to store treated drinking water. The drinking water tank is sent to the household with a chlorine-containing solution and instructions for use. Whenever DSI's drinking water technicians visit each household, they check that the drinking water tank is being used correctly and whether a chlorine-containing solution needs to be added. Technicians read tag data through NFC phones, and the software loaded on the phone guides the technicians to ask questions about drinking water. They then send the data to the DSI headquarters via SMS. This application uses the Frontline SMS platform.
Haiti's country is mountainous, and the transportation and communication networks are relatively backward. It is quite difficult to supply clean drinking water to mountain residents. Since the devastating earthquake in 2010 and the outbreak of cholera in October of the following year, it has become very important to quickly organize and supply clean drinking water, especially in the event of natural disasters and serious infectious diseases. The current goal of DSI and NRC is to try to solve the problem of clean drinking water in the home in a short period of time by using chlorine disinfection. With RFID technology, the reported information is reliable and rich enough in real time. The system can also verify that the staff did visit each family. Since there is no need to record the report in words, the technician can visit more families.
According to DSI, the system for chlorination of drinking water is called Gadyen Dlo, which Haitians call a drinking water guard to reduce the incidence of cholera epidemics by about 50%. But if health workers do not have regular family visits, locals will quickly return to drinking unclean water, which will promote the spread of cholera and other infectious diseases.
The organization has already visited 35,000 families in Haiti, and they plan to visit more families to use resources more efficiently.
Mikko Nikkanen, director of business development at UPM RFID, said: "After experiencing a major disaster, the key issue is the need to organize quickly, while saving time and resources and trying to protect the health of residents. NFC technology is fast and cost-effective. The method can support and restore the local environment of the hardest hit area. This environment has become fragmented and the original infrastructure has disappeared. From a systemic point of view, it does not require much investment or complicated processing. Management, tracking and tracing, using NFC phones and RFID tags, sometimes without the need for network support, can get good results."
Deep Springs International (DSI) is a non-profit organization headquartered in Pennsylvania, Nokia Research Center (NRC-Nokia Research Center), and Palo Alto, Calif., and three companies working together to ensure clean drinking water in Haiti using NFC technology. supply.
