Jelly-covered plankton that look like tapioca are multiplying in many Canadian lakes, clogging up water pipes and potentially disrupting the food chain.The population of freshwater plankton called Holopedium has doubled in Ontario lakes between the mid-1980s and the mid-2000s, reports a study published this week in Proceedings of the Royal Society B. The plankton are thriving in lakes that are low in calcium — and the calcium levels of many lakes have fallen in recent decades because of acid rain and logging.
The amount of water used for power generation in the United States is staggering:
Thermal power plants in the US used as much water as farms did in 2005, and more than four times as much as all US residents….
In 2008, power plants in the US withdrew 60 to 170 billion gallons of freshwater every day from rivers, lakes, streams and aquifers, while using 2.8 to 5.9 billion gallons.
The difference, 57.2 to 164.1 billion gallons per day, is the amount of water lost to evaporation in the cooling process.
Groundwater arsenic poisoning in Bangladesh: An interview with Dr Manzurul Hassan Re-blogged | P R S
There were waterborne diseases such as diarrhoea in Bangladesh due to the drinking of untreated water several decades ago. During the 1970s, UNICEF and some international donor agencies advised the Government of Bangladesh to tap groundwater for drinking purposes. Drinking this groundwater actually reduces the level of diarrhoea, but at the same time it is increasing the risk of arsenic poisoning, leading to arsenicosis,hyperpigmentation, gangrene, and finally cancer.
The latency time of cancer symptoms is 15-30 years depending on arsenic content in the water and the period of ingestion. Local poor people are not actually aware of arsenic poisoning. They still think that tube well water is good quality and that it is much better than the surface water, whether it is contaminated with arsenic or not.
As the regulations were developed, detailed lists were drawn up, classifying hundreds of Canadian communities’ water treatment systems as low, medium or high risk.
But the department won’t say what communities it deemed “high risk.”
A Global News freedom-of-information request for just that information came back almost completely redacted – all details censored but the province.
