New version of the Drinking Water Ordinance tightens standards for arsenic and lead
The latest version of Germany’s Drinking Water Ordinance has been in effect since the summer. The Ordinance prescribes new, lower permissible limits for a variety of substances, such as arsenic and lead. Our GEH® Granular Ferric Hydroxide helps impacted water suppliers to adhere to the stricter standards.
In our everyday business, the protection of the environment is always an issue, whether it is the treatment of drinking water or the purification of wastewater. However, the production of our adsorption media also has an impact on the environment. Therefore, we have been operating an environmental management system for several years in order to avoid harmful effects of our operational processes.

In July of this year, a workshop on „water treatment and water recycling in India“ took place in Hamburg. Our Head of R&D Carsten Bahr was there to discuss the challenges with German and Indian experts. In addition to many other issues like water recycling, the removal of arsenic from groundwater to produce drinking water is an important concern in India. Arsenic-contaminated water is still a major problem for the population, particularly in rural areas.

Since the summer of 2021, a waterworks in the North Eifel town of Mechernich has been trialling the use of GEH® 102, an adsorbent based on granular ferric hydroxide, to remove lead from drinking water. The results achieved to date show that GEH® is very effective and can safely remove high concentration levels of lead in raw water of 100 µg/L and bring them down to below the limit of determination.

Both public and private wells can be affected by natural occurring arsenic. In the case of private wells in particular, there is a risk that higher arsenic levels will go undetected during periods of drought.

In the course of a scientific cooperation project with the Hydrogeochemistry Work Group at the University of Mainz and the
Institute of Environmental Technology at Technische Universität Berlin, a model was refined for predicting the service life of
granular ferric hydroxide (GEH) filters in the uranium removal process for water. This was then laboratory and pilot tested
using the available data.
The inauguration of our very own photovoltaic system is just the latest in a long line of energy management system activities: through this development, we have shown that SMEs also have the potential to make significant energy savings and, in doing so, to reap the economic benefits.
