In the early stages, the symptoms of ALS -- also called Lou Gehrig's disease -- include: 1  Increasing weakness in one limb, especially in a hand. 2  Difficulty walking. 3  Clumsiness of the hands. 4  Fasciculations, which are subtle, light twitches under the skin.  Impaired speech.
The Safe Drinking Water Act (SDWA) Section 1417(a)(1) required that after June 19, 1986 only lead free pipe, solder or flux could be used in the installation or repair of any plumbing in residential or non-residential facility providing water for human consumption, which is connected to a Public Water System.
Finally, contamination of drinking water with lead occurs primarily from the use of lead solder joints or old fixtures, and occasionally, from the use of lead pipes. As with many metals, lead was used in a number of health remedies, some of which are still available and used by some ethnic groups. Lead continues to show up in a range of products, many destined to be used by children. Because lead is cheap and easy to use it is found in jewelry and other trinkets.
