DWS brings aquatic expertise to Hauzenberg
The Freudensee in Hauzenberg is facing ecological challenges: Increasing cyanobacterial blooms have been affecting water quality and the bathing experience for several years. To address this issue, the DWS Hydro-Ökologie GmbH has been commissioned by the City of Hauzenberg to carry out an aquatic ecological monitoring program and to develop a restoration concept.
Over the summer months, the DWS team conducts regular sampling of the lake and performs comprehensive analyses of the collected data. In addition, key ecological parameters are assessed to identify the underlying causes of the pollution.
Based on these findings, a tailored set of measures is developed to sustainably improve water quality and to ensure the long-term use of the Freudensee as a recreational bathing site.

Insight into the Fish Fauna of Burgenland
In cooperation with the Burgenland Nature Academy, our Managing Director Georg Wolfram delivered an online lecture on the fish fauna of Burgenland. More than 50 species of fish and lampreys inhabit a wide range of habitats in the region – from flowing waters and Lake Neusiedl to even the smallest drainage channels.
The lecture highlighted their diverse ecological requirements and demonstrated why fish are indispensable indicators of healthy aquatic ecosystems. Using engaging examples, it became clear how sensitively this animal group responds to environmental changes and why protecting their habitats is a key contribution to conserving biological diversity.
With high demands on quality and accuracy of the analytical results, we have established a quality management system for our chemical testing laboratory according to the guidelines of ÖVE/ÖNORM EN ISO/IEC 17025. In September 2010, the laboratory was accredited as a testing laboratory by the Federal Ministry of Economics, Family and Youth (BMWFJ):
BMWFJ-92.714/0659-I/12/2010 Identification No. [PSID] 315.
Our analyses are carried out in accordance with national and international standards (see scope of accreditation). The correctness of our work is regularly monitored by auditors of Accreditation Austria and confirmed several times a year by international interlaboratory comparisons.
