You've seen Bear Grylls turn foul water into drinking water with little more than sunlight and plastic. Now, academics have added a third element -- carbon-dipped paper -- that may turn this survival tactic into a highly efficient and inexpensive way to turn saltwater and contaminated water into potable water for personal use.

Changes in climate can rapidly impact even the deepest freshwater aquifers according to hydrologists. The researchers found that responses to climate variations can be detected in deep groundwater aquifers faster than expected -- in many cases within a year.

Accidental introductions of non-native species has been of increasing concern since the 1980s when human-mediated transportation, mainly related to ships' ballast water, was recognised as a major route by which species are transported and spread.

Non-indigenous species are harming indigenous species and habitats in the Mediterranean Sea, impairing potentially exploitable marine resources and raising concern about human health issues, according to a new study.

The incidence of particular skin and liver tumors on white suckers collected from some Wisconsin rivers corresponded to the degree of urban development within the watershed. Further research is needed to understand the relationship between exposure to urban-sourced contaminants and the initiation, promotion, and potential for population-level effects of these tumors.

As a result of the globalization of trade and transport, in the past decades, tens of thousands of species have spread into regions where they were not originally at home. Potentially serious consequences of this include the displacement or extinction of native species and the spread of health risks. Even though trade flows are known to represent an important path for the introduction of invasive species, this fact alone is not enough to explain the observed distribution patterns of species.

Upgrades to a wastewater treatment plant along Ontario's Grand River, led to a 70 per cent drop of fish that have both male and female characteristics within one year and a full recovery of the fish population within three years, according to researchers.

The quality of our rivers and lakes could be placed under pressure from harmful levels of soluble phosphorus, despite well-intended measures to reduce soil erosion and better manage and conserve farmland for crop production, a new study shows. The team of international scientists found that increased levels of soluble phosphorus in rivers entering Lake Erie, in the USA, may be linked to conservation measures.
