Sensors made from gallium nitride can be placed in any body of water to deliver real-time, continuous monitoring of water quality.
While tackling water problems around the world, it is very hard to get the right data at the right time to help speed up the decision making process to manage the water problems. Getting access to real time water data can help make better watershed management, water pollution and water supply decisions. Having data about the entire water system, rather than about specific points along the system, will also help tackle the water problem immediately.
Collecting the data regarding the water is currently a long and cumbersome process: You first physically collect the sample of water along certain specific points. You then take this to the laboratory and test the small sample for specific contaminants. This process only helps prove a hypothesis, it doesn’t throw light on the current situation without any assumptions.
Getting real time access to water quality data can be effective in any and all countries alike. Important steps can be taken by the authorities like the EPA, Water Corporation and Department of Water
- Governments and Water (utility) departments
- Private companies working in sustainability and water management
- Communities around critical water sources
Process of implementation:
The process needs to be customized for each water body in each region/country. An overall process flow that is necessary involves: Partnership with the government or respective utility department -> Invest in buying the sensors -> Deploy the sensors along the entire water system -> Track and monitor the data -> Use data to make relevant water system decisions
Some examples where I think this would be very relevant:
- Polluted water systems clean-up efforts: Like the Gowanus Canal or the Ganga river
Development around crucial water systems: Like the Ala Wai Canal in Hawaii or that entire watershed
