Arsenic may be found in water which has flowed through arsenic-rich rocks. Severe health effects have been observed in populations drinking arsenic-rich water over long periods in countries world-wide. 0.01 mg/L was established as a provisional guideline value for arsenic.
Based on health criteria, the guideline value for arsenic in drinking-water would be less than 0.01mg/L.
Because the guideline value is restricted by measurement limitations, and 0.01 mg/L is the realistic limit to measurement, this is termed a provisional guideline value.
10 parts per billion (USA, Canada, WHO).
This should be safe. The USEPA has an arsenic standard for drinking water of .010 parts per million (10 parts per billion). This is for total arsenic both organic and inorganic. Toxicity varies as the type. The minimum detection limit for arsenic is in the 1-5 ug/L range (1 to 5 ppb). Use of asenic contaminated water above the drinking water standard should cause no problems if the water is not drunk during the shower.
the answer is 29
"As dangerous as tobacco smoke?" (There are traces of benzene, arsenic, cadmium, lead, formaldehyde, chlorine, polonium and a lot more chemicals in drinking water.)
No. Arsenic is poisonous, so the poison in the water would be metabolized by the vegetables, and then the vegetables would be toxic.
Safe drinking water usually comes from the lakes or
In most communities, tap water is safe for drinking.
Between 50 ppm and 300 ppm is safe. Better below 100 ppm.
The European Union specification for drinking water contain a maximal permitted value for the ion bromate (not bromide): 0,01 mg/L.
This is historical stuff. Decades ago, arsenic was used as a rat poison and also as a pesticide on tobacco and many other plants. Traces of pesticide remained on the plants and that's how it entered both the food-chain and tobacco. Although its use has been banned, traces of arsenic are absorbed by ALL plants from the environment. Drinking water contains arsenic from the same source. Government agencies set safe levels for it in drinking water. A tumbler of drinking water can contain the same amount of arsenic as hundreds of cigarettes and still be considered "safe". "Healthy" oily fish and cereals contain the more modern rat poison, Vitamin D3. Another widely used rat poison is one of the most prescribed drugs, Warfarin.

using a safe fountain for clean drinking water
Arsenic is an example. If it gets into the water supply, the water is not safe to drink. So the water is said to be contaminated.
