Freshwaters are waters that circulate on the soil’s surface. Freshwaters are produced by the run-off generated by rain or by increased groundwaters flows. Once it occurs, freshwaters follows the path of least resistance and may flow in currents such as in rivers and streams or still water such as lakes or reservoirs.

The quality of rivers and streams varies according to seasonal flows and may change significantly because of rain and the effluents it receives. In general, lakes and reservoirs have less sediment than rivers; however, they are subjected to greater impacts from a microbiological point of view.

With the aim of guaranteeing water protection and promote its sustainable use that ensures the long term availability of the natural resource, Adasa has developed a series of equipment designed to achieve this objective, which may be individually implemented or integrated in stations or networks of water quality monitoring and alert. According to environmental sensitivity and the characteristics of the environment, it is interesting to analyze specific physical-chemical characteristics and/or potentially contaminating substances, which leads to decide what products satisfy the requirements in each situation.
