There are always bacteria lurking in dental equipment, suggests research
Bacteria lurking in the water lines at the dentist's office are tougher than we thought, according to a new paper published in Water Research. The study reveals that the disinfectants recommended by companies that manufacture the water lines don't actually shift all the bacteria in the lines, which means they're never completely clean. (2016-02-16)

Checking water quality at the tap
When consumers turn on a faucet, they expect the drinking water that gushes out to be safe. A new report in ACS' journal Environmental Science & Technology found that US public-supply tap water generally meets all enforceable standards. However, routine testing for most prospective contaminants is carried out before water is distributed, not where it's used, and the report indicates some consumers are exposed to contaminant mixtures that aren't commonly monitored.

Ecological Farming May Cause More Heavy Metals In The Soil
Some systems of ecological arable farming which use only organic fertilisers contaminate the soil with levels of cadmium, copper and lead which are twice as high as when a combination of animal manure and artificial fertiliser is used. This had been demonstrated by environmental scientists at Wageningen Agricultural University. (1999-02-08)

Exploring one of climate's 'known unknowns'
Researchers at the University of Bristol with collaborators from ETH-Zurich have shown that the rate of condensation of water on organic aerosol particles in the atmosphere can be very slow, taking many hours for a particle to change in size. This could have significant consequences for understanding how clouds are formed, affecting climate. (2012-07-02)

Even hurricanes have silver linings
Hurricanes may not be all bad, despite the destruction caused by storms like Floyd. While a hurricane's impact on the environment is often drastic, scientists from NOAA and USGS point out that there are some non-destructive aftereffects too. (1999-09-16)

High-efficiency water treatment using light using a novel UV-light system

Fraunhofer researchers have developed a photochemical reaction system in which water can be reliably treated at high flow rates by UV light without having to add chemical catalysts. (2014-05-07)

UC Riverside scientists isolate microorganisms that break down a toxic pesticide
Scientists at the University of California, Riverside report that they have isolated microorganisms capable of degrading endosulfan, a chlorinated insecticide widely used all over the world and is currently registered to control insects and mites on 60 U.S. crops. Endosulfan is a persistent organic pollutant (POP) that enters the air, water, and soil during its use and manufacture. Owing to the persistence in the environment, residues of endosulfan can enter the food chain and directly affect public health. (2003-02-27)

Using microbes for the quick clean up of dirty oil
Microbiologists from the University of Essex have used mixed consortia of bacteria to break down and remove toxic compounds from crude oil and tar sands. These acidic compounds persist in the environment, and can take up to 10 years to break down. By using this microbial mixture, complete degradation of specific compounds was achieved in only a few days. (2009-09-07)

Epiphytes (plants without roots) are being investigated for their use as markers of climate change in rainforests. Monica Mejia-Chang from Cambridge University, UK, will present her research on how changes in photosynthesis and water evaporation in these plants could indicate the effects of climate change over the past 50 years. (2005-07-12)

New research shows crude oil chemicals move and change more quickly than EPA standards
The EPA lists about 65 chemicals as 'toxic pollutants' under the Clean Water Act, 16 of which are polycyclic aromatic hydrocarbons, or PAHs. Researchers conducted studies on a chemical class of PAHs that is not on the EPA's list -- Dibenzothiophene, or DBT, found in crude oil. They studied how these chemical compounds move and change over time, which revealed new information that differs from the EPA standards. This new research was published today. (2017-03-03)

Does water flow become unstable in all soils?
A water movement model created by researchers at the University of California-Riverside and described in the February issue of Vadose Zone Journal has serious implications for agricultural water management. Scientists studied what causes water to break up into narrow channels called fingers. These fingers can move water and chemicals below the crop root zone, which increases the possibility of ground water contamination. The researchers suggest that longer and less frequent watering might decrease this possibility. (2003-02-14)

New water management tool may help ease effects of drought
Continued improvement of climate forecasts is resulting in better information about what rainfall may look like months in advance. A researcher from North Carolina State University has developed an innovative water management framework that would take advantage of these forecasts to plan for droughts or excess rain in order to make the most efficient use of an area's water resources. (2009-11-12)

Too much sugar not good for coral reefs
The race is on to buy up inexpensive land along coastlines for vacation homes and tourist hotels. But increased development can mean more nutrient rich runoff that threatens the very coral reefs attracting tourists in the first place. David Kline at the Smithsonian Tropical Research Institute and colleagues find that bacteria on coral reefs grow out of control as the level of simple sugars in seawater increases. (2006-02-17)

MSU entomologist appointed to unravel mysterious tropical disease
A tropical skin disease nicknamed (2005-10-12)

Why is ice so slippery
The answer lies in a film of water that is generated by friction, one that is far thinner than expected and much more viscous than usual water through its resemblance to the 'snow cones' of crushed ice we drink during the summer. This phenomenon was recently demonstrated by researchers from the CNRS and ENS-PSL, with support from the École polytechnique, in a study that appeared in Physical Review X on Nov. 4, 2019 (2019-11-05)

Cause of abnormal groundwater rise after large earthquake
Abnormal rises in groundwater levels after large earthquakes has been observed all over the world, but the cause has remained unknown due to a lack of comparative data before & after earthquakes. After the 2016 Kumamoto earthquakes, a collaboration of scientists from Japan and the US analyzed stable isotope ratios of water samples collected before and after the disaster. This allowed them to clarify the cause of the rise in water level. (2020-07-01)

Lettuce quality is improved by modifying its growing conditions
A researcher in the UPV/EHU's department of Plant Biology and Ecology has confirmed that it is possible to improve the nutraceutical quality of the lettuce by modifying its growing conditions but not at the expense of productivity. The FisioClimaCO2 research group, to which the researcher Usue Pérez-López belongs, has applied various stress conditions to the plants and has verified the changes that take place in their composition as a result. (2015-11-27)

Study indicates thirsty plants keep deserts' subsurface dry
Desert vegetation might reduce water accumulation in soil should the climate shift toward wetter conditions, according to a study conducted by a team led by University of Texas at Austin hydrogeologists. Also, such vegetation keeps water from reaching the water table deep below the surface in such areas. Because plants can maintain dry conditions, minimizing leaching of wastes into underlying aquifers, important implications exist for radioactive and hazardous waste disposal, the study's results show. (2005-04-11)
