Reflected water quality also on landscape scale



News, Water & Waste Water

In a study published in the high-ranking journal Earth-Science Reviews, David Piatka of Friedrich-Alexander-Universität Erlangen-Nürnberg and other authors from the AquaKlif project, which is funded by the Bavarian Network for Climate Research, examine the role of dissolved oxygen in rivers. Its continuous input is necessary for organisms living in the water and is endangered by many factors. Using global measurement data, the study shows that because rivers integrate the biogeochemical information of entire catchments, their oxygen dynamics can provide important clues about the “health” of surrounding ecosystems and landscapes.

Dissolved oxygen is one of the most important elements for the majority of aquatic life – but equally a scarce commodity because its solubility is limited. Water temperature, flow gradient in streams and rivers, and adjacent land use affect oxygen levels in streams and their sediments. Stream bottom sediments, in particular, are important habitat for numerous aquatic and aquatic-dwelling species, where quite a few animals spend the egg or larval stage. The authors summarize the major sources and sinks of dissolved oxygen in river systems and discuss its role in adjacent lakes, reservoirs, soils, and groundwater.


“After the literature search required for a review paper, our own analyses were exciting, in which we worked with Romy Wild of the Technical University of Munich to evaluate more than 170,000 dissolved oxygen measurement data from the Global River Chemistry database. In this way, we learn not only about the living conditions in the river and on its banks, but also what the situation is like in the many small tributaries and their surroundings. With this method, we can even estimate how intact nature is there for the entire catchment area. Extensive analysis of the available data suggests that climate warming may become critical for aquatic ecosystems simply because of lower oxygen solubility in warmer waters.”

– David Piatka, lead author


The researchers conclude by suggesting ways to further improve monitoring of rivers – which are often seen as “integrators of entire landscapes.” In addition to high-resolution concentration measurements, better knowledge of residence times and sources and sinks of oxygen are important. Newer methodological tools such as stable isotopes, iron conversion analysis, biological studies, and measurement of radon gas dissolved in water can help. These techniques are currently being developed and applied in the AquaKlif project.

“The article brings to light many facts about dissolved oxygen in rivers for the first time on a global and continental basis” emphasizes Prof. Johannes Barth, in whose Applied Geology group David Piatka is doing his PhD. “It is equally important to study the conversion of this vital element in detail. What do balances look like in small rivers, how is oxygen transported into sediments and at what rates is it converted there? These are crucial questions for local functioning of aquatic ecosystems.” These water-bound communities are also close to the heart of Prof. Jürgen Geist of the Technical University of Munich: “The availability of dissolved oxygen is of crucial importance for living organisms in water bodies. The article has succeeded in providing a holistic and global view of the importance and conversion processes of oxygen in water bodies. From an understanding of these processes, important indicators of the state of aquatic systems can be derived.”

“Our article in the renowned journal Earth-Science Reviews is a successful example of joint approaches in the collaborative project, which brings together expertise from geosciences, hydrology and biology and can thus propose innovative methodological approaches” says hydrologist Prof. Dr. Stefan Peiffer from the University of Bayreuth, who represents the AquaKlif project as spokesperson.


Wastewater treatment plant in Tübingen now has fourth treatment stage



On July 21, 2021, Helmfried Meinel, Ministerial Director at the Baden-Württemberg Ministry of the Environment, visited the wastewater treatment plant in Tübingen, where he inaugurated the construction of the so-called fourth treatment stage. The fourth treatment stage will allow residues of pharmaceuticals and household chemicals to be filtered out of wastewater. “The elimination of trace substances is precautionary water protection,” Meinel emphasized. In Tübingen in particular, this plays a major role, he said, because it means that fewer trace substances end up in the Neckar River.

The Ministerial Director explained that Tübingen is only the second wastewater treatment plant in Baden-Württemberg, after the treatment plant in Eriskirch, to use an ozonation plant with downstream filtration for the elimination of trace substances. “Tübingen is thus one of the pioneers for this process combination in Baden-Württemberg. The big advantage is that it has a broad effect.” He said it is effective for a wide range of pharmaceuticals, hormones and numerous other substances. Even germs can be removed from wastewater.

20 wastewater treatment plants have been equipped with the fourth treatment stage so far

With a view to prevention, Meinel explained further, the Ministry of the Environment began several years ago to support the expansion of wastewater treatment plants with innovative processes for the so-called fourth purification stage for the elimination of trace substances. In doing so, the state is concentrating on particularly sensitive bodies of water, as well as large wastewater treatment plants and pollution hotspots.

“On this basis, 20 wastewater treatment plants in Baden-Württemberg are now equipped with a targeted purification stage for the removal of trace substances, and another 23 with this special technology are under construction or in planning.”

State contributes almost three million euros in Tübingen

The state is contributing almost three million euros to the total eligible costs in Tübingen of almost 13.8 million euros. “This is money well invested,” Meinel said. In addition to the city of Tübingen, the municipalities of Ammerbuch and Rottenburg are also financing the expansion.

The ministerial director also praised the fact that with the completion of the expansion and the commissioning of filtration in Tübingen, phosphorus elimination has now been raised to an even better level. “Aquatic animals and plants also benefit from this, because the ecological condition in the Neckar can be noticeably and sustainably improved.”

Flood victims receive tax aid



The heavy rain and flooding not only claimed lives, but also caused enormous economic damage. To account for the material damage, the finance ministries of the states of North Rhine-Westphalia and Rhineland-Palatinate as well as the Bavarian State Tax Office have each enacted disaster decrees. Thomas Loibl from Ecovis in Landshut explains which tax support measures flood victims can receive.


What happens if my accounting records were destroyed by the water?

If accounting documents and other records have been destroyed or lost due to the storm, there are no adverse tax consequences to be drawn from this. Important: The affected taxpayer should document the destruction or loss in a timely manner and, to the extent possible, provide proof or credible evidence.


What can business owners do to mitigate the significant financial burdens?

The respective disaster decrees contain more than 20 tax support measures for taxpayers who are directly and not insignificantly affected – for private individuals as well as special regulations for entrepreneurs. Some examples from both:

Deferral and enforcement measures as well as adjustment of advance payments.
Note: Affected parties can submit the applications until October 31, 2021.

Deferral and remission applications for trade tax.
These applications must be submitted to the municipalities.

Special depreciation options for reconstruction
This allows expenses on a larger scale to be taken into account immediately to reduce taxes.

Special regulations for agriculture and forestry and income from renting and leasing
Farmers and landlords can take advantage of additional support measures.

Possibility to waive property tax
Interesting for all house and apartment owners.

Expenses for existentially necessary items (apartment, household goods, clothing) as extraordinary burdens

How are donations eligible?

The obligation to provide proof of donations has now been simplified. In addition, donation campaigns can also be organized by non-profit corporations that, according to their articles of association, do not promote charitable purposes, for example, or are regionally bound.

Furthermore, so-called donations from wages and salaries are possible. In this case, an employee waives payment of part of his or her salary. The employer pays this amount into a donation account of an institution entitled to receive donations. The donated portion of the salary is then not taken into account as wages. No payroll tax or social security must be paid. “However, the employer must fulfill and document the use requirement. Important: The donated salary must be recorded in the payroll account,” says tax consultant Thomas Loibl.

Tip: Even expenses for existentially necessary items (apartment, household goods, clothing) can be taken into account for tax purposes. In exceptional cases, these can be deducted as extraordinary expenses.
