lead, poisonous gas emmissions...you are talking about damage...this stuff can kill you

no\nthe water evaporates too fast to cause any harm

It all depends on the pollution in the water, the depth, the time of year and weather in the area.

Considering our water these days you just have to consider two factors (A) its salty (B) its most likely dirty.\n\nEffects of drinking contaminated water:\nhttp://www.walrus.com/~gatherer/interpret.html#health

Absolutely not. But there have been cases where subtherapeutic levels of fluoride have been added to the water, too little to do any good. Happened in my town.

Don't fully understand question.  Hydrosphere means water so anything that could contaminate water (forest fires that pollute with ash, chemicals, etc.  Type in hydrosphere harm and see site below.

Among the most dangerous of all water pollutants is fuel oil. Oil spills from tankers at sea or leaks from underground storage tanks on land are very difficult to control as oil tends to spread very fast, affecting a large area in a very short time. They are a major menace to the environment as they cause severe damage to surrounding ecosystems.

Tap water.\nSoap breaks down the surface tension.

Yes, soil moisture.\n\nBut how about the degree of ionicity of the soil; wouldnt that depend on the kinds of minerals in the soil (which is likely to vary as well)...\n\nCordially,\nJohn\nhttp://www.GodSci.org

The Water Pollutance is when the water is dirty for non naturals causes.\n\nFor example, in a stream, the water pollution could be affect this place and the people maybe can't note that ... Why? because, some pollution agents are unseen to the human eye ... for example ... NO2, NO3, S, P, etc, etc ... all this elements in excess in a stream, river, creek, lagoon,  wherever place whit ater ... could be contaminated ...\n\nBut, you could get more information in this link:\n\nhttp://www.dbmain.biz/4/water-pollution/epa%20water%20pollution\n\nIs a link from EPA .... Enviromental Protection Agency...\n\ngood luck !!!!\n\nPD: Please, excuse my english .. I'm learning to write in this Idiom.

Maybe the MgCl woulf affect the plant by some chemical reaction i dunno what you are asking.

Environmental effects\n\nModern mining companies in many countries are required to follow strict environmental and rehabilitation codes, ensuring the area mined is returned to its original state, or an even better environmental state than before mining took place. Past mining methods have had, and methods used in countries with lax environmental regulations continue to have, devastating environmental and public health effects. The result can be unnaturally high concentrations of some chemical elements over a significantly wider area of surface. Combined with the effects of water and the new 'channels' created for water to travel through, collect in, and contact with these chemicals, a situation is created where mass-scale contamination can occur.\n\nEnvironmental issues can also include erosion, formation of sinkholes, dangerous sites such as deep holes in child friendly communities, destruction of the environment, loss of biodiversity, and contamination of groundwaters by chemicals from the mining process and products.\n\nSome examples of environmental problems associated with mining operations are:\n\nAshio Copper Mine, Ashio, Japan was the site of substantial pollution at end of the nineteenth century \nBerkeley Lake, an abandoned pit mine in Butte, Montana that has filled with water which is now acidic and poisonous. \nScouriotissa, a copper mine in Cyprus that has been abandoned. Contaminated dust blows off this site. \nTar Creek, an abandoned mining area in Picher, Oklahoma that is now an Environmental Protection Agency superfund site. Water in the mine has leaked through into local groundwater, contaminating it with metals such as lead and cadmium. \n\nAlthough such issues have been associated with some mining operations in the past, modern mining practices have improved significantly and are subject to close environmental scrutiny.

When toxic substances enter lakes, streams, rivers, oceans, and other water bodies, they get dissolved or lie suspended in water or get deposited on the bed. This results in the pollution of water whereby the quality of the water deteriorates, affecting aquatic ecosystems. Pollutants can also seep down and affect the groundwater deposits.\n\nWater pollution has many sources. The most polluting of them are the city sewage and industrial waste discharged into the rivers. The facilities to treat waste water are not adequate in any city in India. Presently, only about 10% of the waste water generated is treated; the rest is discharged as it is into our water bodies. Due to this, pollutants enter groundwater, rivers, and other water bodies. Such water, which ultimately ends up in our households, is often highly contaminated and carries disease-causing microbes. Agricultural run-off, or the water from the fields that drains into rivers, is another major water pollutant as it contains fertilizers and pesticides.
