It has been known to cause a number of ecological issues, including toxic algal blooms, a decrease in biodiversity, and increased health risks for plants, […]
Freshwater scarcity is a growing concern, placing considerable importance on the accuracy of indicators used to characterize and map water scarcity worldwide. We improve upon past efforts by using estimates of blue water footprints (consumptive use of ground- and surface water flows) rather than water withdrawals, accounting for the flows needed to sustain critical ecological functions and by considering monthly rather than annual values.
Farmers in Illinois and much of the Midwestern Corn Belt are facing significant challenges stemming from nutrients that are being lost from their farm fields. These lost nutrients, especially from nitrogen fertilizer, are getting into waterways and causing problems in local drinking water supplies, as well as feeding the hypoxic or dead zone in the Gulf of Mexico.
“Water banking” is an emerging term in western Colorado as water planners work on concepts to protect water supplies in the face of long-term drought, increasing demand and the uncertainties of a changing climate.
South Africa is a water-constrained country with a vital need to conserve, manage, and expand its limited water resources as efficiently as possible. Municipalities are now discharging around 4 billion litres of untreated or partially treated sewage into the country’s rivers and dams every day.
The issue arose when officials from the OCWD began to observe unusual spikes “in arsenic after it percolated into soils and sediments from surface basins into underground storage aquifers”. What was specifically unusual was that the water that absorbed this excess arsenic had “undergone a rigorous purification process”.
Many people live in subdivisions with storm water ponds, which collect water from the neighborhood and help keep pollutants such as fertilizers, pesticides and pet waste from getting into the broader environment. Now, researchers have devised strategies to help homeowners limit their pollution contribution.
Sometimes utilities, especially those with publicly elected boards, defer the maintenance of their equipment because raising taxes or rates is unpopular with voters. But updating outmoded infrastructure and securing access to new water sources amid scarcity and drought are expensive tasks. These efforts are pushing rates upward.
Two years ago in September the Global Water Center celebrated its grand opening, and since then the facility has attracted new businesses, corporations and startups, not to mention a handful of universities too — all of them with the same focus: water technology.
The Los Angeles Department of Water and Power may spend hundreds of millions of dollars for water treatment
Earlier this month, the city of Hamilton received a certificate of recognition from the Ohio Environmental Protection Agency for “exceptional implementation of drinking water source protection strategies,” according to a press release issued by the city on Saturday.
