H2O Quality

H2O Quality, the app that gives you access to water quality data in Lisbon

This application, which works through georeferencing, gives you access to water quality results for your location, with daily updated information in Portuguese and English.

At any time, wherever you are, you can access H2O Quality and see the water quality being distributed at that specific location, with information on various parameters, namely calcium, magnesium, chlorine, colour, hardness and pH, amongst others, which you can refer to in detail by viewing results and parametric values.

With this free application, you can also view the location of drinking fountains near where you are on the map, refill your reusable bottle and take tap water with you, the most sustainable and environmentally friendly option. You can also find out where you can buy a Fill Forever, the 100% eco-friendly EPAL Reusable Bottle.

In addition, more detailed information on EPAL's water sources, various treatment phases and water quality control is available for consultation.
