In Canada, cyanide has been known to be released into the water system from mining and milling industries and industrial processes like steel plants. There have also been instances of cyanide appearing in raw water supplies due to runoff from land where salt had been applied. The Guidelines for Canadian Drinking Water Quality require that less than 0.2 mg/L be present in drinking water. (http://blog.aquasafecanada. com/cyanide/ 5/2/2015)
Bacteria, viruses, parasites, arsenic, fecal matter, and more have been found at different times in drinking water. It is amazing how many contaminants are in our drinking water! No one should be swallowing arsenic. According to the EPA, if it is likely that no ill effects are LIKLELY then that level of arsenic is okay in drinking water. The following taken directly from their site:
"What are EPA's drinking water regulations for arsenic?
In 1974, Congress passed the Safe Drinking Water Act. This law requires EPA to determine the level of contaminants in drinking water at which no adverse health effects are likely to occur. These non-enforceable health goals, based solely on possible health risks and exposure over a lifetime with an adequate margin of safety, are called maximum contaminant level goals (MCLG). Contaminants are any physical, chemical, biological or radiological substances or matter in water."
Some contaminants are unregulated through the EPA. Does it make you feel better to know that these contaminants are tested for every five years? Not all of them though. There are a maximum of NO MORE THAN 30 CONTAMINANTS monitored every five years- that is 28 chemicals and 2 viruses from 2012- present.When someone pours their dirty oil in the ground, that oil gets into our water table and contaminates the drinking water. When someone flushes pills down the toilet, or puts them in a drain, that contaminates our water. Estrogen in water will affect our children's future growth."
"The U.S. Geological Survey study showed that estrogen exposure reduces a fish's ability to produce proteins that help it ward off disease and pointed to a possible link between the occurrence of intersex fish and recent fish kills in the Potomac and Shenandoah rivers."

The CDC said that lead can be found in drinking water if you live in a house that has lead pipes. Older houses are more likely to have this problem. Lead exposure can cause reproductive issues, high blood pressure, brain damage in children, and other serious health issues. They believe that "Water is not normally considered the major source of pollution exposure to lead. In individual households with lead piping and soft waters it may be important." It would seem that NO LEAD should be allowed to pass through a water test. However, the health based guideline for lead in drinking water is 0.1 milligrams per litre (WHO, 1993).
What about bacteria and viruses? In 1993, over 400,000 people ingested a parasite through the drinking water in
Milwaukee, Wisconsin and became ill from it. E. Coli is spread into the water system through irresponsible care of animal waste. Giardia is spread among other ways through cross contamination of sewage and water lines. In developing countries, people can get a parasitic worm called a helminth through the drinking water. Since America has not had an much of a problem with them, we rarely test for this parasite. Does that mean it lurks in our water? Not necessarily, but do you want to find out the hard way it is there? (http://extoxnet .orst.edu/faqs/safedrink/microorg.htm)
