1. The National Primary Drinking Water Regulations are the National standards that public water systems must meet. They are the nations legal rules that are enforceable. The regulations are important to us because they protect us from unhealthy or high levels of contaminants in our public drinking water.
2. The Safe water Drinking Act enables the EPA to set minimum standards and enforce public water systems to comply with the minimum standards in water. This Act affects all waters that are used or potentially can be used for drinking water in the US. IT does not affect bodies of water that are not used for sources of tap water.
3. Prior to 1996 Public water systems were defined to include only piped water systems. In 1996 the EPA amended the definition to include" constructed conveyances" that provide water for human consumption, such as irrigation canals. The Definition of Public water systems because it defines how the water gets to the treatment plant and is serving as drinking water for human consumption.
