The Gaza Strip faces a severe contaminated water crisis, with the only source being unsuitable for drinking due to high levels of salinity and pollution. A proposed management plan aims to provide a win-win situation but requires cooperation between Israel and Palestine.
A team of researchers, including Rensselaer Polytechnic Institute, has developed a network of distributed sensing devices and water-monitoring robots that use solar power to extend their deployment time. This technology will enable the detection of chemical and biological trends in lakes, rivers, and waterways to improve water quality ...
The Midwest Technology Assistance Center is funding research to optimize iron addition and track arsenic concentration variability in relation to time and pumping procedures. The center also evaluates water quality at surface water intakes with watershed modeling to improve small systems' technical, managerial, and financial capacity.
Researchers discovered that 11 of 17 measurable chemicals in surface water were reduced after passing through the system, according to Ron Turco, soil microbiologist. The study showed that constructed wetlands can act as a holding area for recycled water, providing a sustainable solution for irrigation and flood prevention.
The study models seasonal distribution of BOD and DIN to identify areas at greatest risk for low water quality. Unmanaged shrimp mariculture development leads to increased BOD and DIN, causing oxygen depletion and harming aquatic life.
Researchers analyzed over 100 water samples in the Sierra Nevada and found that more than half had no water quality issues. E. coli and other bacteria pose a greater risk of waterborne illnesses than Giardia in this region.
Research reveals high levels of toxic contaminants in New England rivers, affecting aquatic life and human health. Streams draining even small amounts of urban land show signs of degradation, while fish from rural areas accumulate higher mercury levels.
A recent study highlights the importance of implementing sanitary growing and harvesting conditions worldwide to reduce the risk of human disease outbreaks linked to fresh produce. Plant pathologists emphasize the need for good quality irrigation water and sanitary worker conditions, particularly as international imports increase.
A study found that California's beach warning system incorrectly notifies the public about coastal water quality up to 41% of the time. The research identified tidal outlets as major contributors to pollution along the shore, suggesting a need for improved warning systems and approaches to managing storm runoff.
The Gaza Strip's groundwater is becoming contaminated with salts and nitrates due to over-pumping, threatening the water supply. A joint study suggests tapping into saline water from Israel and desalinating it could help preserve freshwater resources and alleviate pressure on the aquifer.
Scientists are studying the impact of human activities on water quality in the Brush Creek watershed. Geophysicists have discovered small earthquakes in northeastern Kansas related to movements of the Earth's crust. Additionally, researchers are analyzing how irrigation affects summertime climate in the High Plains.
A telephone survey of 1,988 Chesapeake Bay watershed residents found concern about pollution and importance of restoration, yet a lack of individual stewardship activity. To encourage action, agencies must inform citizens about their role in pollution and how their actions can improve water quality.
A recent study found a strong correlation between beach pollution and lunar cycles, tidal forces, and sunlight exposure. This could lead to inaccurate warnings and economic losses for local businesses.
Researchers studied surf water quality at Huntington Beach, Calif., and found that flawed sampling methods may be responsible for beach closings. The study highlights the complexity of controlling coastal water quality and raises questions about existing monitoring programs.
A new NSF grant aims to evaluate the costly impacts of corrosion on water quality, drinking water tastes and odors, and home plumbing. Researchers will focus on economic, consumer, and biochemical dimensions of potable water infrastructure corrosion.
A California-funded Sea Grant survey banned the sale of Caulerpa taxifolia, a fast-growing tropical seaweed, due to its invasive nature. Meanwhile, researchers used DNA technology to identify E. coli sources, tracing human and animal fecal pollution in Lake Michigan.
Changes in agricultural practices have led to improved water conditions on Lake Erie, with phosphorus levels from fertilizers decreasing by over 50% for all seasons. Climate change also played a role, increasing nitrogen levels by up to 500% due to winter runoff and soil leaching.
Professor Christer Bruun of the University of Toronto reveals that ancient Rome's aqueducts were technological marvels that brought clean water to over 1 million people. The Romans separated high-quality water for drinking from water used for flushing, a practice still lacking in many modern cities, including Canada.
The study highlights the loss of large predatory fish as a key factor in altering marine food webs, leading to changes in ecosystem composition. Historical records suggest that fishing impacts may have begun thousands of years ago, contributing to current ecosystem level changes.
The Suquamish and Port Gamble S'Klallam tribes are working together with geologists to manage water quality through a long-term approach. They have established staff gauges and monitoring wells, as well as implemented wetland protection programs and watershed studies to protect their water resources for at least seven generations.
Marine scientists at UNC-CH and Duke University have launched a ferry-based water quality monitoring system in the Neuse River, generating valuable data for analysis. The system, called FerryMon, aims to evaluate and model how Pamlico Sound's ecosystem responds to human and natural impacts.
The USGS is developing simulation models to evaluate the effects of proposed remedial actions on stream chemistry in abandoned mine lands. These models are applied to St. Kevin Gulch, a small stream near Leadville, Colorado, providing estimates of water quality that reflect the impact of proposed actions.
