Scientists conducted several tests and found that the solution in the reservoir is 2% arsenic. Although scientists realize that the arsenic can't be removed from the supply, they do understand that they can reduce the percentage to safe levels. A safe level of arsenic is .001% How much water must be added to the reservoir to make the water safe to drink? </SPAN>\n" );
