IMPROVING WATER QUALITY MONITORING AND PARTICIPATORY MONITORING OF THE AQUA PROJECT APPLICATION

Introduction Water quality monitoring plays a key role in promoting environmental sustainability. Water is a vital resource for life and its availability and quality are intrinsically linked to human well-being and health. Through constant monitoring, it is possible to identify and mitigate pollutants, the Aqua project proposes to present a solution for evaluating and monitoring water quality, using a cell phone application and a very low-cost kit, integrating everything into an online platform. line with the aim of establishing a participatory monitoring network for rivers and water bodies. Results and Discussion The initial version of the Aqua1,2 project application, which is capable of determining: nitrite, organic matter, ortho-phosphate, ammonia and iron, all contaminants of water bodies3, stored the information only on the cell phone itself, and the georeferencing was done in a manual, where the operator himself had to manually record where the sample was taken. Furthermore, it was not available on Google Play, which made it difficult for less skilled people to install it. The application was rewritten, and is no longer local, running exclusively on the cell phone and was migrated to the cloud, now the data is also stored in a public database, where other researchers, or interested entities can have access, the account is no longer be local and is now stored on the internet, georeferencing is also now more accurate, as the application reads the location through the phone's own GPS system, and installation can be done via Google Play, removing one of the difficulties for use of the application. Conclusions With these modifications, the objective of participatory monitoring has now become easier to achieve, as the data of all users can be accessed via the internet, they have become more secure as they are no longer on the device, and the location of the sample location has become much easier. more accurate, in addition to allowing data integration.
