The Importance Of Lead In Drinking Water

The lead in the environment is formed naturally in the earth’s crust mainly as Lead Sulphide. The main exposure channels of lead entering the environment through atmospheric lead is predominantly from automobile emissions. Other lead exposure routes include lead-acid batteries, paint chips, fertilizers, utilized ammunition, pesticides, and other industrial byproducts. The means of conveying lead from key emission sources is mainly through the air. Concerning the sources of lead in drinking water, normally lead reaches into the residents’ water after it is channeled from their water treatment plant or the wells. To be more precise, the source of lead in people’s water supply largely emanates from their households’ pipes or lead solder from plumbing. The most typical cause of the lead formation is from the corrosion reaction by the lead pipes or solders and the water. The acidity as a result of the low pH, dissolved oxygen, and little mineral contents in the water are main reasons of the corrosion. The lead amounts in the water become high if the water spends a long duration of time stagnated inside the old pipes.

The Agency for Toxic Substances and Disease Registry says that lead exposure in children may cause comas, seizures, and death. Because a child’s brain is still developing, the damage of lead exposure is more severe. Not only does lead affect the way the brain physically develops, but lasting neurological and behavioral damage includes lower IQ scores, higher risk of attention deficit disorders and hearing impairments, decreases in impulse control, and potentially violent behavior. Mona Hanna-Attisha, a pediatrician who runs the pediatric medical residency program at Flint’s Hurley Medical Center, studied blood lead level tests and found that the percentage of children with elevated blood lead levels had gone from 2.4 percent to 4.9 percent citywide (Barry-Jester). Hanna-Attisha’s findings showed a rise to sixteen percent in neighborhoods where lead levels were known to be elevated in the water. She points out, "Lead only last in body a short time … and when you screen them, it's no longer elevated. So we've missed children's peak lead levels and that's why everyone says it

All the inhabitants of Flint communities regardless of their location had irreversible, permanent brain damage due to lead-contaminated water. It started when traces of E. coli and total coliform were found in the Flint River. The city addressed this problem by increasing chlorine levels in the water, causing the pipes to corrode, releasing lead into the waters. Total trihalomethanes (TTHM) were also formed in the water (they are carcinogenic to humans).TTHM is a disinfection byproduct that occur when chlorine interacts with organic matter in the water. At this stage, The lead levels in the water was 13,200 ppb. Water is considered hazardous waste at 5,000ppb (NPR 2016). This tragedy goes to show that this toxic runoff, or even the miss-handling of the water resources in a watershed can affect everyone as the downstream water was piped up into the upstream communities.

In Flint Michigan, nearly 100,000 residents are drinking lead contaminated water. (QuickFacts). We are not discussing a third world country on the other side of the globe, but rather a city in the United States. It would seem as though the land of opportunity, and the land many flee too should be able to provide clean drinking water. However, in the United States 310,000 children aged 1-5 are found with an unsafe level of lead running through their blood stream. (Lead 8). In Flint alone, 8,000 children under the age of six have been exposed to harmful levels of lead. The agencies and government that was put into place to protect the public from these issues is often turning a blind eye, and often allowing the public to continue to drink this contaminated water. A major part of the problem is that lead water pipes run throughout cities across the United States. Although it would very expensive to replace all the water pipes running through Flint, not replacing the pipes could potentially continue to do more harm to the ecosystems, and to the communities they are in.

Potential lead contamination from drinking water presents a significant health risk. Recent examples of this lead contamination include Flint, Michigan, a city that experienced a large increase in the number of people, especially children, who exhibited symptoms of lead poisoning. A March 9, 2016 article in the Washington Post reported data from the Environmental Protection Agency that indicated approximately 350 schools and day-care centers across the US failed lead tests approximately 470 times between 2012 and 2015. Seven years ago, according to the Post, a study concluded that hundreds of young children in Washington, DC, had potentially damaging amounts of lead in their blood due to contamination in the city’s tap water. The toxin can cause permanent developmental and behavioral issues.

In Flint Michigan studies show there was a large amount of lead in the water , because of this high turbidity in the water witch means this water is dangerous.

Imagine you're drinking a cup of water and every single drop is poison. This could be happening to you. 50% of the United States have lead in their drinking water. This is because of lead based pipes. Lead based pipes have been leaching lead into water which connects to drinking water. It can also be because of the state's water utilities that might have lead in their water. ( EPA's safe drinking water information system database reports, three, 2016 by Isabella DC, USA Today) says Lead can cause brain damage, cancer, seizures, hearing loss, learning disabilities, and more!

The rules for lead and copper have changed over the years, so let’s start at the beginning. Lead was originally regulated under the Public Health Service Act of 1962, which established a guideline of 0.050 mg/L (ppm) for lead in drinking water. This was carried over into the Safe Drinking Water Act of 1974. It wasn’t until 1991 that regulation changed significantly under the Lead and Copper Rule. This rule regulates how public water supplies must deal with the potential of lead and copper in the drinking water. Additionally, there is also the Reduction of Lead in Drinking Water Act, which regulates the amount of lead that can be in products that could come into contact with drinking water, like pipes, plumbing fitting, fixtures, solder and flux.

Imagine being informed that the water with which you bathe, brush your teeth, and cook is the root of many serious and sometimes fatal health problems. Sadly, this is the case for a majority of the citizens in Flint, Michigan. According to an online article titled “This is how toxic Flint’s water really is,” by reporter Christopher Ingraham, the culprit is high concentrations of lead that have leached into tap water from lead-containing pipe systems and fixtures as they slowly corrode. The article also informs that although nearly all citizens were exposed to the hazardous water, some exposures were found to be worse than others (Ingraham). Additionally Ingraham states “A group of Virginia Tech researchers who sampled the water in 271 Flint homes last summer found some contained lead levels high enough to meet the EPA 's definition of ‘toxic waste." With lead being the culprit, and nearly all citizens being exposed to the contaminated water, Flint has found itself in a near epidemic.

As a leading plumbing services provider in Collin County, TX, Tri Star Plumbing knows about the dangers that can be associated with certain types of plumbing problems, like catastrophic water leaks and natural gas explosions. But the one danger that is rarely discussed is the danger of exposure to lead in old plumbing pipes and fixtures. For homeowners whose homes were built before the federal Safe Drinking Water Act Amendments of 1986 were passed, there is a strong likelihood that lead pipes, faucets and fittings are a part of their plumbing systems; and that means that they and their families are consuming water contaminated with lead.

Flint, Michigan, is approximately 70 miles away from the largest body of fresh water in the world, the Great Lakes. Ironically, its residents cannot access clean water from their taps. The Flint water crisis began in April 2014, when the state chose to save money by switching Flint’s water supply from Lake Huron to the Flint River, a source of water that is apparently filthy. Now, the city is in a state of emergency as they struggle to access clean and consumable water, while there are reports of lead contamination creating a huge epidemic health problem. Since the crisis, children are the primary demographic with high lead counts in their blood. Detrimental health effects include, skin lesions, hair loss, high levels of lead in the blood, depression and anxiety.

The improved screening and treatment of lead poisoning decreased the severity of symptoms usually seen. However, the level of lead in the blood does not establish what symptoms are seen, since lead in blood only establishes current exposure. Recently, studies have shown that a long exposure to low amounts of lead may have severe neurobehavioral effects that are not diagnosed until the child enters school (Singhal et. al., 1980).

Lead, a naturally occurring metal and can be used in almost everything. It can cause serious health issues if it is exposed for a long time, particularly in children as they are more susceptible to absorbing and retaining lead in their bodies. Each year, in the United States 310,000 of 1- to 5-year age group are found to have unsafe levels of lead in their blood, which can cause a wide range of symptoms. (1)

Lead poisoning relates to skin lesion, hair loss, vision loss, memory loss, depression, and anxiety. Many pediatricians found high levels of lead in children’s system. Young children, infants, and fetuses are particularly vulnerable to lead because the physical and behavioral effects of lead occur at lower exposure levels in children than in adults. A dose of lead that would

It rather is becoming a problem due to pollution. A recent and highly publicized lead poisoning case was that of Flint, Michigan’s water supply. Lead poisoning in the U.S. is generally caused by contaminated water. Lead in the public water supply is generally due to absorption from lead pipes or solder. Absorption of lead into water has been found proportional to the temperature of the water. Unsurprisingly, the warmer the water, the higher the lead concentration; however, the change in lead concentration compared to the temperature shift is quite surprising. Ơ Between 10 and 23 degrees Celsius, it has been shown that a 1 degree shift in temperature can change the dissolved lead concentration by 5 percent. Δ Another factor which impacts the amount of dissolved lead in tap water is water
