Bacteria can ensure clean water say researchers
(10/24/2006) Water is shaping up to be one of the most critical problems facing humanity. With water consumption far outstripping population growth rates due to surging industrial and agricultural demand, the World Bank estimates that 40 percent of the world's population -- more than 2.5 billion people -- are enduring some form of water scarcity. In China, where massive river relocation projects to shift water from the south to the dry north are under consideration, an official government survey found that some 300 million Chinese drink unsafe water tainted by chemicals and other contaminants, while 90% of China's cities have polluted ground water. Elsewhere, development experts say that access to reliable, safe and affordable water is key to poverty alleviation efforts and that addressing declining groundwater supplies and water pollution is be critical to raising the quality of life in poor regions.

An increase in air temperature over the last four decades has contributed to a substantial reduction in glacial cover, they say.

(05/12/2006) India could face worse droughts according to a new study by scientists at Scripps Institution of Oceanography at the University of California, San Diego. In a study published in the May 15 issue of Journal of Climate, Chul Eddy Chung and V. Ramanathan of Scripps Oceanography say that cooler-than-normal temperatures in the northern part of the Indian ocean have weakened the region's natural climate circulation and monsoon conditions, resulting in reduced rainfall over India and increased rainfall over the Sahel area south of the Sahara in Africa,

Ancient water supply of Sahara at risk, satellite monitoring helps in water management
(12/19/2005) During the last Ice Age, the Sahara was savannah with rivers, lakes and plentiful rains. Over the past 10,000 years that landscape changed, but the rains from that period progressively percolated beneath the ground to be collected in aquifers. Today these aquifers are an important source of water for irrigating agriculture and supporting human populations in the area.
Climate change means less water for western US by 2050, more for Montana
(11/17/2005) USGS scientists simulated the impact of future climate change on global water availability. By 2050, the models predict increased water runoff in eastern equatorial Africa, the La Plata basin and high latitude North America and Eurasia. They predict decreases in runoff in southern Africa, southern Europe, the Middle East and mid-latitude western North America. The authors of the paper, which appears tomorrow in Science, say climate climate will result in costly disruptions to water supply and resource management systems.

Amazon at record low -- communities isolated, commerce stalled
(10/11/2005) The Amazon River in Peru and parts of Brazil is at its lowest level in 30 years of record keeping. While variable water levels are characteristic of the Amazon river ecosystem, the increasingly extreme fluctuations are of great concern. Low water levels are wreaking havoc on the shipping industry in the region. In Iquitos, a city in the heart of the Peruvian Amazon which is only accessible by plane or boat, ships and barges are having difficulty navigating the river, resulting in serious shipping delays. Local officials in Peru are blaming deforestation of the upper reaches of the Amazon in the Andes for the fall in river levels, although it is likely that larger forces are at least equally important. Warmer ocean surface temperatures in the Pacific and low sunspot activity is also affecting weather in the region, while warming in the north Atlantic -- which has helped trigger an unusually strong and destructive hurricane season -- may be preventing the formation of rain clouds over the Amazon Basin.
Extreme drought drops Amazon river to record low levels
(10/07/2005) The Amazon River in Peru and parts of Brazil is at its lowest level in 30 years of record keeping. While variable water levels are characteristic of the Amazon river ecosystem, the increasingly extreme fluctuations are of great concern. Low water levels are wreaking havoc on the shipping industry in the region. In Iquitos, a city in the heart of the Peruvian Amazon which is only accessible by plane or boat, ships and barges are having difficulty navigating the river, resulting in serious shipping delays. Local officials in Peru are blaming deforestation of the upper reaches of the Amazon in the Andes for the fall in river levels, although it is likely that larger forces are at least equally important. Warmer ocean surface temperatures in the Pacific and low sunspot activity is also affecting weather in the region. Brazilian meteorologists have discounted the theory that the severe hurricane season off the US Gulf coast has impacted the availability of moisture in the Amazon.
Amazon river at record low levels; deforestation blamed
(09/30/2005) The Amazon River in Peru is at its lowest level in 30 years of record keeping according to a report in Peruvian daily newspaper El Comercio. Local officials say deforestation is the likely culprit of the low water levels. While variable water levels are characteristic of the Amazon river ecosystem, the increasingly extreme fluctuations are of great concern.
EPA advisory for health safety in flooded areas
(09/07/2005) Floodwaters from six locations across the New Orleans area were sampled by EPA and analyzed for chemicals and bacteria. Preliminary information indicates that bacteria counts for E. coli in sampled areas greatly exceed EPA's recommended levels for contact. At these levels, human contact with water should be avoided as much as possible.
