Decline of freshwater species
The decline of biodiversity
represents a loss of natural capital for future generations. Freshwater
ecosystems are particularly affected. So far, measures to protect genetic
diversity in rivers and lakes have failed to halt the downward trend. What is
widely underestimated, according to Eawag scientists, is the extent to which
reduced habitat diversity also prevents species formation, thus accelerating
the spiral of decline. [...]

'Self' container destroyed by fire
Shortly after 2.15pm on Good Friday, 2nd April, the Self container for
autonomous living and working burned to the ground. The self-contained unit,
which is completely independent of mains water and energy services, is a joint
project of Empa, Eawag, the Zurich University of the Arts (ZHdK) and the
University of Applied Sciences of Northwestern Switzerland (FHNW). The unit was
located on an area of open grassland adjacent to the Museum for Design in
Zurich's District 5. The fire services succeeded in extinguishing the flames but
could not save the building. [...]

Measuring rainfall with mobile phone antennas
As
rain interferes with radio signals, Eawag researchers have been able to measure
rainfall using data supplied by the mobile telecommunications company Orange. The
new method offers greater spatial resolution than traditional point measurements
provided by rain gauges. In the future, this could be combined with intelligent
control systems for sewer networks so as to reduce water pollution in urban
areas. [...]

Toxic arsenic removed from fields by monsoon floodwaters
As a result of irrigation
with arsenic-rich groundwater, this toxic substance can accumulate in paddy
soils and – at high concentrations – may ultimately find its way into rice
plants. In a study published in Nature
Geoscience, researchers from Eawag and the ETH Zurich collaborating with
scientists from Bangladesh have shown that a certain amount of arsenic is released
from soils into floodwaters during the monsoon season. [...]

Swiss strategy against micropollutants
Last Thursday, the Swiss Federal Office for the Environment
(FOEN) presented its synthesis report on the MicroPoll project, in which Eawag
played a major role, to the media. The conclusion drawn by the chief Swiss
environmental authority in the report is that retrofitting 100 wastewater
treatment plants is the most effective way of preventing contamination from
micropollutants in urban drainage systems. Complementary to this, measures are
also needed to reduce contamination at the source. [...]

Arsenic in the water - Eawag - The Bright Star in the Research Sky
Science Watch generates "star maps" of a different kind. The science
monitoring agency of Thomson-Reuters detects networking patterns by analysing
publications and the frequency of their citation. This analysis shows the
trend-setting articles in the respective field of research and their
interconnection. In April 2009, Science Watch concentrated on the issue "Arsenic
Water Pollution". Not very surprising: among the 24 "core papers" (of the period
2003-2008), no less than five were written at Eawag or with the participation of
Eawag researchers. [...]

Drinking Water in the 21st Century
In the cross-cutting project
Wave21, Eawag carried out research on future methods of drinking water
treatment with a variety of private-sector and water utility partners. The
Final Report – “Wave21: Drinking Water in the 21st Century” – has now been
published. The integrated project focused on supplies sourced from surface
waters, and in particular on the relationship between raw water parameters and individual
treatment steps. [...]

Solar Water Disinfection put to test
A recent study [1] of Solar Water Disinfection
(SODIS) has attracted substantial media attention for its negative findings on
the SODIS process, in which water is disinfected by placing it in PET bottles
and exposing it to sunlight. The investigators reported that the incidence of
diarrheal diseases was not significantly decreased in an intervention group as compared
with a control group. The authors of the study suggest to "hold off"
on new promotion campaigns for the method. This would be wrong. [...]

Sex to keep parasites at bay
One
of the most fascinating questions in biology is why large parts of the animal
and plant kingdom go to the trouble of reproducing sexually. A study led by
Eawag has now shown that, in the long run, sexual reproduction offers
advantages in protecting populations against parasites. [...]

Micropollutants in water resources: prevention - assessment - removal
Sooner or later, chemicals
– and increasingly also nanoparticles – from textiles, pharmaceuticals,
cosmetics or construction materials inevitably end up in natural waters. Here,
they may pose risks for animals and plants, or even for drinking water safety
and human health. Eawag has shown that precautionary measures should involve
more than general water quality standards, as the effects of contaminants need
to be assessed in a highly specific way. Particular emphasis is to be placed on
preventing inputs to receiving waters: in many places, for example, pollution
is decreased by the expansion of stormwater retention facilities, and – thanks
to cooperation between researchers and industry – changes in the production and
use of bitumen sheets mean that the leaching of biocides can be dramatically
reduced. [...]

Vietnamese medals awarded to Eawag scientists
Four Eawag scientists today received official medals from the Vietnamese
government for their achievements in the areas of drinking water quality and
sanitation. The medals were awarded in recognition of “outstanding contributions
to education and training in Vietnam”. With financial support from the Swiss
government, the scientists succeeded in strengthening capacity at two research
centres in Northern Vietnam and improving the quality of local water supplies
and wastewater management. [...]

Jurassic Park from a Swiss lake?
Ecological changes caused by humans affect natural biodiversity. For
example, the eutrophication of Greifensee and Lake Constance in the 1970s and
1980s led to genetic changes in a species of water flea which was ultimately
displaced. Despite the fact that water quality has since been significantly
improved, this species has not been re-established. This was demonstrated by
researchers from Eawag and from two German universities (Frankfurt and
Konstanz), who analysed genetic material from Daphnia eggs up to 100
years old. [...]

Eawag Forum Chriesbach: reaping the rewards of sustainable construction
A
five-storey office and research building for 220 people that requires
scarcely more energy from external sources for heating and cooling than
one or two single-family houses? Eawag’s Forum Chriesbach fits this
description. At a meeting held today, two years after the building was
opened, the architects, planners and clients concluded that the
results, in terms of energy use and costs, have been positive. The
internationally renowned Forum Chriesbach is already regarded as a
model for a new generation of buildings, even though there is still
room for optimization. [...]

New results from climate research using ice cores
A 139m long ice core drilled in the Siberian Altai has now provided new
findings in climate research. Oxygen isotopes in the ice were used to
reconstruct the temperatures in the Altai over the past 750 years. The
scientists discovered a strong link between regional temperatures and the solar
activity in the period 1250-1850, concluding that the sun was an important
driver of preindustrial temperature changes in the Altai. [...]
