This Lab we explored how contaminants affect the water supply. Contaminants can be commonly found in household products from dish washing soap to paint, to oil and more. There are more robust versions like pesticides and petroleum products within the farm system. We will explore why and how this affects the water table and what type of effects, if any, we will witness drinking water from the tap.
Water is the key to serving and what humans do in everyday live effect the water and the animals that depend on that water to live. When using chemicals in everyday house cleaning that is putting harmful things into the ground and then into the animals and then back into the human body.
Proving that that the chemical and other things that are used in the everyday clean is harmful to the animals and to the plant. Will be doing some experiments to make it clean that what is said is not what the government wants everyone to believe.
Working in the environmental field one contaminant I come across frequently is Lead. It is found frequently in older homes. It has been found in paint, canned goods and in our water supply. Research has shown that lead poisoning can lead into developmental issues, negatively harm the reproductive system and can ultimately lead to cancer. Lead from environmental pollution is not carcinogenic, but even low dose lead exposure has been shown to have detrimental and long-lasting effects on the renal, homeopathic and nervous system (Fertmann et al., 2004). And while more is being done the United States is far from coming up with a homogenous solution. The U.S. Environmental Protection Agency (U.S. EPA, 2011a), as directed by the Safe Drinking Water Act of 1974, has determined that no amount of lead in drinking ...

... water crisis will have a long term affect on those who are consuming this water on a daily basis. Lead attack the brain and can cause coma and possibly death. Children who survive lead poisoning are left with serious health issues such as metal defects and leave a child mentally unstable. Even at lower levels of exposure symptoms such as behavioural changes such as reduced attention span, reduced intelligence quotient (IQ). Children with smaller amount of lead exposure also showed increased anti social behaviour, it also reduces educational attainment. These side effect of high lead exposure can leave children scarred for life. The water crisis in Flint Michigan car scar children for life. This could all be resolved if they could come to an agreement and replace the water pipes, allowing for cleaner and healthier water to be accessible to citizens in Flint Michigan.
This is why the Flint water crisis is so critical today. Because young children are being exposed to lead and they should actually be screened from the lead. The pipelines with lead in the water system and the whole community of Flint, not being able to drink water out of the facet as well as not being able to
Lead is a metal found virtually everywhere even today. Sources of lead include auto body shops, electric storage batteries, glazes for china dishes, crockery, insecticides, electric cable insulation, hose, pipe, sheet and floor coverings. Lead is associated with stain glass work, jewelry making and antique ceramic doll painting. Although lead in paint was outlawed, there are still many homes that have lead paint (White et al, 1990). Lead found in gasoline was found in one study to account for 23--27% of the lead blood levels in the people tested (Wagner, 1991). This exposure to lead sources is more of a concern for children due to the characteristic habit of children to taste everything they touch; this characteristic is known as pica. Children are also in closer contact with their lead polluted environment during play. They are more active and exposed to outdoor contaminates and they inhale dust and dirt that are lead contaminated. Furthermore, the adsorption rate of lead in the digestive tract is up to 10 times greater in chil...
When lead enters the environment, it starts to become a problem. After a period of about ten days, depending on the weather, it falls to the surface. Here lead builds up in the soil particles. Where it may make its way into underground water or drinking water due to the fact the grounds acidic or if it's soft enough. Either way it stays a long time on the soil or in water. Months or years down the road after the lead has built up it starts to become a problem for children that play outside of their homes . This lead containing soil particles get on the child's hands or clothing and end up in the child's mouth. After the build up of so much lead it leads to lead poison. Lead poisoning has been an issue since the early 1900s, when the use of lead started being banned from the manufacturing of paint in foreign countries such as Australia. Unfortunately, the United States did not start banning it until 1978, when it finally became illegal in our nation. Today 90% of the lead in the atmosphere comes from the burning of gasoline. This problem has been a large issue since the 1920s, when the Environmental Protection Agency started making laws on the amount of lead allowed in gasoline.
...f inorganic arsenic may be a danger to human health. The exposure to arsenic is higher for people who work with arsenic, also for people who drink significant amounts of wine. People living in houses that contain wood preservatives, and live on farms where arsenic pesticides have been applied in the past are highly exposure.
There are differences in the primary routes of exposure, Babies and children can swallow lead through breast feeding. They can be exposed to lead in the womb if their mothers have lead in their bodies. In children ingestion is the major route of exposure. Lead paint is the major source. In older houses as the lead paint deteriorates, peels, chips or is...
Arsenic is the 20th most common element in the earth’s crust and can be found naturally in our environment. There is around 0.006 to 0.03 ppm or arsenic distributed in seawater, and 20 ppm of arsenic in soil (before pesticides). Every human will ingest about 0.5 to 1 mg of arsenic in a day from food and water, because arsenic is present in higher quantities in se...
Such is the condition of Texas waterways. The surging population in Texas, the numerous pharma, chemical and oil industries, landowners, farmers and other residents have been recklessly using water. Water is a limited resource and our best efforts in recycling, reusing and conserving water have not yielded the desired results. Climatic changes over the past few decades may have resulted in unpredictable rainfall in Texas. It is important to conserve water without polluting it. It is shocking to know that the drinking water has traces of arsenic, cyanide, nitrates, asbestos and mercury and lead. U.S. Environmental Protection Agency (EPA) and the National Geological Survey after conducting studies have shown that water samples containing growth hormones, various antibiotics,birth control drugs, and many other chemicals end up in ground water. The Trinity River is highly polluted with bacteria from sewage. The high water pollution in Texas State by various sources causes environmental hazards and life threatening diseases like cancer and nerve damage; thus the government and community should intensify their efforts to reduce pollution and make drinking water safe.
Due to an above average level of poverty, many homes in New Orleans had very high levels of lead and arsenic in them. (Pastor) This combined with eighty percent of the city being flooded, released significant amounts of lead and arsenic into the environment which still exist today. Soil samples taken before and after Katrina showed elevated levels of lead, iron and arsenic. (Reible)A new study on one-hundred and nine households found that sixty-one percent had lead measurements above federal standards with twenty-seven percent greater than one-thousand two hundred ppm which was significantly higher than the five-hundred and sixty ppm collected before Hurricane Katrina. (Rabito) These inorganic compounds are related to cancer risks of which New Orleans already has a significant problem with. This complicates the decision on when and where to conduct environmental clean-ups in New Orleans to remove the lead, iron and arsenic.

Symptoms of lead poisoning include loss of appetite, weakness, anemia, vomiting, and convulsions, sometimes leading to permanent brain damage or death. Children who ingest chips of old, lead-containing paint or are exposed to dust from the deterioration of such paint may exhibit symptoms. Levels of environmental lead considered nontoxic may also be involved in increased hypertension in a significant number of persons, according to studies released in the mid-1980s. As a result, the U.S. Centers for Disease Control in recent years have been revising downward the levels of environmental lead that it would consider safe.
Today's waters are constantly being treated like sewage dumps or trash cans. We use them as garbage cans every day polluting the water more and more. "Pollution is often by way of rivers, drains and outflow pipes." Causing an outflow of sewage into our ocean waters. This is not only affecting the community but also the marine life and other sea creatures living in the ocean." This pollution includes human sewage and domestic waste water, factory outflows of acids and poisonous metals, engine oil from roadside drains and garages, farm chemicals washed off the land by rain, building-site rubble, nuclear waste from power plants, and oil from wells, refineries, and tankers." Stating that most of today's waste is from factory or factory ran products that shouldn't be polluting the water

Are you aware of the detrimental impacts that we have had on our environment? Every second, the Earth is being polluted by poisonous gases, waste products and due to human activities, the world’s climate is dramatically changing. In other words, these impacts do not only harm our environment but also our health. It has been scientifically proven that air pollution causes respiratory diseases and cancer, due to the inhalation of all the harmful chemicals. Water pollution can also lead to typhoid, diarrheal diseases and other waterborne disease, due to the intake of bacteria and parasites. Many people have died due to these health-related illnesses. So why are we still living in this awful condition? Air sustains us and water is a basic necessity, so we should do what we can to prevent pollution. In short, we should protect our environment to ensure a healthy life a...
