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.

(Campbell, 2016). Two giants in childhood lead poisoning research and advocacy, Dr. Philip Landrigan and Dr. David Bellinger, summarize the adverse effects of lead very completely, yet succinctly: “Lead is a devastating poison. It damages children’s brains, erodes intelligence, diminishes creativity and the ability to weigh consequences and make good decisions, impairs language skills, shortens attention span, and predisposes to hyperactive and aggressive behavior. Lead exposure in early childhood is linked to later increased risk for dyslexia and school failure.”(p. 3).

The current water crisis in Flint, Michigan stems from government officials changing water sources. The government of Flint switched from using the water of Lake Huron, which they had used for over 50 years, to using the water of the Flint River, which had a high level of chloride. The high chloride level eventually led to the corrosion of water pipes allowing unhealthy levels of chlorine and lead contamination. Additionally, irresponsible and unreliable water treatment allowed even more contaminates to enter the city’s water source. All this pollution ultimately ended up in the homes of thousands of people, poisoning families throughout the city. Lead poisoning can have disastrous effects on the human body, with some symptoms including “memory loss, anemia (lack of healthy red blood cells), kidney dysfunction, and in severe

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.

The lead effects in the drinking water have caused a massive public health crisis (“Scientific Opinion on the risks”, 2015). The whole crisis was as a result of poor management practices employed in the Flint water plant. The city decided to switch the

Many service lines leading into homes are leaching lead into the water. This problem happened because the city of Flint decided to not treat the water properly with corrosion control (Ganrin, 2016). This proves that officials did not care about those living in Flint. They chose to save money but instead they destroyed many lives. So this proves that our government is not there to help the people out, but instead to cut money wherever they feel necessary to not have to take it from other places. Lead poisoning can affect IQ and behavior. This can cause some people to become score low on standardized test and to become violent and to sometimes harm others. No level of lead is ever safe in any person or animal (Ganrin, 2016). The water source in Flint is currently undrinkable and very unsafe and will continue to be for months ahead ("Researcher: Flint water 'like Russian roulette'," 2016). Flint water is not a safe water source and has not been for many months. According to federal regulations Flint's water supply still does not meet standards. Since August 2015 the water supply has improved, but it still is not safe ("Researcher: Flint water 'like Russian roulette'," 2016). The people of Flint have been poisoned under their noses without even knowing it, secretly being sickened by their own government. Flint’s water is not safe it's an unreliable water

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 consuming the water, the children, as of 2015, are consuming 3 times the amount of lead compared to 2013 (source)

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.

“In September, Virginia Tech researchers released a report saying Flint's water was creating a health threat in old homes that have lead pipes or pipes fused with lead solder. And doctors last week reported high levels of lead in local children's blood samples, also blaming water pipes” (CBSNEWS). Lead is a serious problem as it may cause a serious damage in different organs of the body especially the brain and it is the most known neurotoxin. However, knowing that lead is the source of the problem is an important piece of information which can facilitate reaching the source of lead leaching. In fact, many cities have lead pipes, not only Flint city, and when water sits in those pipes, the lead can leech into the water. So cities usually add corrosion-control chemicals, such as phosphates (PO4), to keep the lead out of the water. However, Flint did not take into account these precautions, and this was a major contributor to the high lead levels and, consequently, health problems, “the public health protection was gone,” Edwards says. (ALANA SEMUELS, 29 Jul. 2015). If we talked about the reason why the water in Flint’s River is difficult to treat, it turns out that it contains high levels of coliform and fecal coliform bacteria. But what makes it more difficult than Lake Huron water is that the Flint River is subject to temperature changes, rain events and high carbon content. An additional indication, is the increased level of trihalomethanes (TTHM), a byproduct of the large amount of chlorine needed to kill bacteria in the river water. For the most part, specific amounts of chlorine are used to treat river water, but the problem is that low levels of chlorine can produce coliform bacteria and, on the other hand, high levels of chlorine may result in Disinfectant Byproducts (DBP), which, in turn, may lead to elevated levels of

Back in April 2014, Flint Michigan, switched its water supply from Lake Huron to the Flint River. The government believed that this would be a great idea, because by them making this big switch they begin to start saving a lot of money. The new water that they now use is very polluted. This is the water that each and every person in Flint depends on to drink, cook with and to also bathe in. A lot of people have been affected by this change in water supply. As things begin to worsen the people in Flint, started to hear and become very familiar to lead poisoning. A significant amount of their victims have fallen victim to to being affected by the contaminated water, that everyone has been using. Doctors have noticed that the amount of lead found

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.

Lead poisoning in children was first discovered in 1890 in Queensland, Australia. The lead source was not identified until 1904, when a researcher traced it to the paint used on railings and verandahs. The first discovery of lead poisoning in the United States (with a traceable source) was in 1914; the child had chewed the paint off of his crib. At this time they linked lead poisoning as a cause of convulsions in children. As research progressed and more children were found with high lead levels, symptoms caused by lead were expanded to include lead meningitis, acute encephalopathy, intellectual dullness, reduced consciousness, seizures, comas, and death (Chisholm, 1982).

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)
