The Ministry of Water, Agriculture and Environment, through the Office for Promotion of Socioeconomic Environment, explained that the white foam that visitors can see on the shores of the salt ponds and even in the ways of the Regional Park of Salinas and Arenales of San Pedro del Pinatar not mean that these are contaminated with detergent, but is due to a natural process in which the wind of time plays an important role.
Environment is responding to one of the questions most frequently asked by visitors to this environment.
The key element of the foam is organic matter from the decomposition of the remains of animals and plants that inhabit the salt ponds, which is suspended in the water, but especially in the bottom mud.
These substances are surface-active, which means that favor the formation of bubbles and finally foams.
Foam, commonly known as 'salt foam', is composed of air bubbles enveloped by a liquid membrane.
In appearance it is similar to suds and sea foam.
The difference is that lasts longer due to the large amount of salts in suspension in the water.
The durability is enhanced by the action of strong wind storms.
