For citizens, farmers and water quality managers
The Nitrate App/Deltares Aquality App makes it possible to analyse surface water and groundwater, to isolate nitrate sources and hot spots, and to test the impact of measures. The app is particularly welcomed by people working professionally with water quality such as farmers, water authorities and water companies.
All you need is a reference map, nitrate test strips and a smartphone with the free Nitrate App/Deltares Aquality App installed. After taking a water sample with the test strip, you scan the result and, if desired, share it. If you have no Internet connection, the app will forward the measurement when you connect to Wi-Fi later.
