Question: EPA regulations for harmful contaminants in drinking water set an upper limit of 2.00x10mg/L for thallium. Suppose that your water supply contained TI at a level of 1.03 pob (a) What is this concentration expressed in mo/? ma (b) Would your water supply pass EPA regulations?

Most water sources do have some small amounts of clay or silt, but you should still avoid any drinking source that looks turbid. Clay-contaminated water is unpalatable and unappealing. At the worst, cloudy silt-filled water can impact tourism and recreation by lowering the quality of life in an area. 2. Iron.
