What are the National Primary Drinking Water Regulations? They are standards of water purification that need to be followed to protect the public's health. They are important to us so that we stay healthy. They are important for companies to follow also so they can keep business.
Explain the Safe Drinking Water Act. What bodies of water does this affect? What water does it NOT affect? This is a federal law that makes sure american drinking water is good quality. This act effects rivers and lakes. Also it goes for reservoirs, wells and springs. This does not effect private wells serving less than 25 people.
What is a "public water system"? Give an example of how the definition has changed over time (according to EPA). Why do you think it is important to rigorously define a PSA for the purposes of making laws and regulations? A public water system is a supply to the public for human use through pipes. The definition of public water system has changed because people would drink water coming strait out of rivers and it caused problems for the health of these individuals. The government made it a law that water can only be drunk from pipes and not directly from the source. The purpose of this was to keep people from drinking dirty water and making them sick.
Microorganisms
Giardia lamblia- Health risks include gastrointestinal illness (diarrhea, vomiting, and cramps) This comes from human and animal feces, which is a non-point source pollution.
Legionella- Health risks include legionnaire's Disease, a type of pneumonia. This comes naturally in water systems. This comes naturally so it is non point source pollution.
Disinfectants
Bromate- Health risks include a increased risk of getting cancer. This comes from directly drinking water disinfection. This is a point source pollution.
Disinfection byproducts
Chlorine- Health risks include eye/nose irritation; stomach discomfort. This is because of water additive used to control microbes. This is a point source pollution.
Inorganic chemicals
Arsenic- Health risks include skin damage or problems with circulatory systems, and may have increased risk of getting cancer. This is because of erosion of natural deposits. This is a non point source pollution.
Barium- Health risks include increasing in blood pressure. This comes from discharge of drilling waste. That is a point source pollution.
Organic chemicals
Acrylamide- Health risks include nervous system or blood problems; increased risk of cancer. This is caused by added to water during sewage/waste water treatment. This is a non point source pollution.
Carbofuran- Health risks include problems with blood, nervous system, or reproductive system. This is caused by leaching of soil fumigant used on rice. This is a point source pollution.
Dalapon- Health risks include minor kidney changes. This is caused by runoff from herbicide. This is a point source pollution.
Radionuclides
Uranium- Health risks include increased risk of cancer and kidney toxicity. This is caused by erosion of natural deposits. This is a non point source pollution.
