Health and Safety

Cloudy water does not necessarily imply bad water quality. The wind and the wave movements can influence the water by sand particles. This way the transparence of water can be less. The cloudiness of water results in a bad sight of how deep the water is. Also, one cannot see if there are any obstacles on the bottom of the water, which can cause problems when swimming.
When swimming in open water, one should always take water movements, shipping traffic and abrupt changes in deep/shallow water into account. By swimming in places where supervision is present, one can enhance his/her safety.

The bacteriological status of open water is an important factor, to determine whether the water can be qualified as swimming water. The bacteriological quality can tell a lot about the presence of the germ of a disease. During a warm summer the quality of water can stagnate. If the water reaches 20 °C or more, it can create a breeding ground for botulism. Another problem for water quality are floating alga layers. Some of these layers can contain blue algae, that are poisonous for humans.

Places where rats come, form an increased risk for the illnes of Weil. It is for this reason, why throwing waste on the beach or in the water is forbidden. If someone gets (severe) health complaints after swimming in surface water, he/she should go to the doctor or GGD immediately.
