What is Radium, combined (-226 & -228)?

Radium is a naturally occurring radioactive metal that is part of the uranium decay series. It is found in trace amounts in soil, rock, and water. Radium is known for its radioactive properties and can emit alpha, beta, and gamma radiation. It is a heavy metal and can be harmful to human health when ingested or inhaled.

Health Effects

Exposure to radium can lead to serious health issues, including an increased risk of cancer, particularly bone cancer. It can also cause damage to the bone marrow and other organs. Long-term exposure may result in anemia, immune system suppression, and other health complications.

What is Gross Alpha (Excl. Radon and Uranium)?

Gross alpha activity is a measure of the total alpha particle activity in a water sample, excluding radon and uranium. It is used to assess the presence of radioactive contaminants in drinking water.

Health Effects

Exposure to high levels of alpha radiation can lead to an increased risk of cancer, particularly in the bones and other tissues where alpha particles can deposit energy.

What is Gross Alpha Activity?

Gross alpha activity measures the total amount of radioactivity in a water sample emitted by decaying alpha-emitting elements, notably radioactive isotopes of uranium, radium, and radon. Alpha emitters are used to treat cancer, as an eliminator of static in paper mills and in other products like smoke detectors. Radioactive atoms release high energy alpha particles that pull electrons off of the atoms in cells. This process is called ionizing radiation, and may lead to harmful changes in cells and tissues. The toxicity of an alpha emitter depends on the amount of energy it releases and how organ systems respond to that energy. Exposure to elevated gross alpha activity is associated with increased cancer risk and genotoxicity, but toxicity to individual systems is dependent on the type of alpha emitter present.

Health Effects

Drinking water standards for gross alpha activity have been developed based on increased cancer risk associated with alpha radioactivity. Alpha radiation has been shown to produce DNA changes (genotoxicity) in laboratory studies.

What is Chlorine (Total)?

Chlorine is a chemical element with the symbol Cl and atomic number 17. It is a yellow-green gas at room temperature and is a strong oxidizing agent. Chlorine is commonly used in water treatment to kill bacteria and other pathogens, making water safe for drinking.

Health Effects

Exposure to chlorine can cause respiratory issues, skin irritation, and eye irritation. Ingesting high levels of chlorine can lead to gastrointestinal distress and other serious health problems.

What is Radium 228?

Radium-228 is a radioactive isotope of radium that occurs naturally in uranium and thorium ores. It is part of the decay chain of uranium-232 and has a half-life of 5.75 years. Radium-228 can be found in groundwater and can contaminate drinking water supplies.

Health Effects

Exposure to radium-228 can lead to an increased risk of cancer, particularly bone cancer, due to its radioactive properties. Long-term exposure can also affect the kidneys and other organs.

What is Radium 226?

Radium-226 is a radioactive isotope of radium, which is a naturally occurring element found in uranium ores. It is a decay product of uranium-238 and is known for its radioactive properties, emitting alpha particles and gamma radiation.

Health Effects

Exposure to Radium-226 can lead to serious health issues, including an increased risk of bone cancer and other malignancies. It can accumulate in bones and tissues, leading to long-term health effects due to its radioactivity.

What is Fluoride?

Naturally occurring mineral in the environment and an essential element of tooth enamel

Health Effects

Elevated levels of fluoride in drinking water can lead to dental fluorosis in children, which is the discoloration and molting away of tooth enamel. Evidence on low-dose, chronic exposure to fluoride is not definitive but has been indicated as having potential neurological impacts. Studies have clearly established that long-term exposure to high doses of fluoride, higher than typically found in US drinking water, can have adverse effects on skeletal tissue (bones and teeth), which may cause higher risk of bone fractures in seniors. Skeletal fluorosis is a debilitating condition caused by high fluoride exposure during bone development in children.

What is Aluminum?

Naturally-occurring metal found in the Earth's crust with multiple industrial uses, including the construction of buildings and powerlines, and the manufacture of vehicles, consumer electronics, household appliances, and kitchenware. It is also frequently used in municipal water treatment to clarify water from lakes and reservoirs. Health effects of aluminum exposure are inconclusive but actively researched.

Health Effects

Much of the current research on the health effects of aluminum in drinking water is still inconclusive and controversial. Health protective benchmarks for aluminum in drinking water set by the California Office of Environmental Health Hazard Assessment are based on potential neurotoxicity and developmental toxicity in premature infants. People more susceptible to aluminum impacts include infants and people with impaired kidney function.
