Water-Cleanup Experiment causes Lead Poisoning

Lead causes problems in a child’s nervous system. The District of Columbia’s water authority tried to clean the water supply another way by using chlorination and it worked for the time being. This cleaned the water but large amounts of lead were found in the water supply. The chlorine caused the lead in the plumbing line to increase in the water supply. Even though engineers said that they water was claimed to be fixed it had already affected many children. The risk of this problem not being fixed could cause permanent damage to children’s neurological systems. Based on a survey in 2004 it was reported that kids had not suffered from the lead levels. Early studies showed no damage was done to children, so another study was do. This second study showed that the groups tested in 2004 was not the appropriate group who could have been infected. During the lead crisis the water had 100-1000 ppb (parts per billion) when it should have had only 15 ppb. Much damage was done from 2001-2004. More kids are likely to have behavioral problems and Attention Deficit Hyperactive Disorder. It is estimated that kids IQ can drop 4-7 points because of this. An average of a five-point drop is scary because it could cause many people in America to fall in the Mentally Retarded level. This isn’t just happening locally in Washington but also in other parts of the nation as well as all over the world. Attention needs to be put on protecting children from such dangers.
