Gropa is a park in Drammen that offers a popular bathing area. During the period from June to August, the municipality conducts weekly water tests to assess the water quality. The results from these tests are classified as good, less good or not suitable for bathing, which provides visitors with information about the safety of bathing in the area.
Water quality can be affected by weather conditions, and poor quality often occurs after heavy rainfall. To ensure that visitors have access to up-to-date information, it is possible to find bathing areas with the latest test results. In addition, general recommendations for bathing based on the assessed water qualities are offered, as well as information about the methods and criteria used to assess bathing water quality.
