Chemical Water Pollution Many industries and farmers work with chemicals that are dumped into water. These include chemicals that are used to control weeds, insects and pests. Metals and solvents from industries can pollute the sources of water. These chemicals are poisonous to the living organisms in water and may slow their growth, make them sterile and can kill them. 8.
Water is one of the most important everyday source for everyone, also used as domestic and industrial purpose. Water pollution occurs when people just throw plastics or other wastes to the water which turns into poisonous chemical waste. “WHO estimate that diarrhoeal disease accounts for approximately 3.6% of the total DALY global burden of disease, and of this it is estimated that 58% is attributable to unsafe water supply, sanitation and hygiene, most of which is in developing countries” (WHO, 2014). Water pollution is mostly suffered by the organisms that survive in water. In human perspective, people die every day due to polluted and infected water.
In many developing countries, the main cause of death is diarrhea contracted by drinking water. Human and animal wastes are not the only water pollutants. Sometimes pollutants can come from an oil spill or another single source. When this occurs, it is called point source pollution. (“ Categories of Pollution: Point Source”, 2008) The global picture of water and health has a strong local dimension with some 1.1 billion people still lacking access to improved drinking water sources and some 2.4 billion to adequate sanitation.
For example, gas, road salt, and other harmful chemicals can dissolve in water. As a result, they can soak into the ground through rainfall and contaminate the water underground. Groundwater contamination is very serious and deadly, as it can cause a variety of bodily complications, including but not limited to: Hepatitis, poisoning, and cancer. Generally speaking, we face two major issues in trying to get rid of toxic chemicals in our freshwater. The first issue is the fact that we don’t know how to stop the chemicals from getting into our groundwater, as the contamination of groundwater cannot be seen, heard, or felt.
If these synthetic solids are not removed, they may cause biosolids to be rejected for reuse as a soil amendment. Large amounts of grit and sand entering a treatment plant can cause a serious operating problem that is needed for treatment. Grit includes sand, gravel, cinder, or other heavy solid materials that are “heavier” than the organic biodegradable solids in the wastewater. Removal of grit prevents unnecessary abrasion and wear of mechanical equipment, grit deposition in pipelines and channels, and accumulation of grit in anaerobic digesters and aeration basins.
“Water pollution happens when toxic substances enter water bodies such as lakes, rivers, oceans and so on, getting dissolved in them, lying suspended in the water or depositing on the bed” (WWF), thus leaving us with less fresh water. Furthermore, one of the ways humans, and many creatures, survive is by staying hydrated and to stay hydrated is it essential to intake water. Many of use drink water from the tap, but there are still chemicals about,“119 regulated chemicals—a total of 260 contaminants altogether—were found by the environmental group… analysis of more than 22 million tap water quality tests” (West). This is an issue where it needs to be addressed for the protection of human health. There is many pollution in water that Humans and creatures drink in, chemicals and waste are still in our tap water.
When washing your car, use a bucket instead of a hose. Having permeable outdoor surfaces like gravel, as well as gardens, also minimizes runoff but gardens can also have a negative effect. For example elements found in fertilizer such as phosphorus and nitrogen, aid in escalation in algae growth when it is introduced to a body of water, which kills off existing aquatic life in the area. The toxins also affect humans in a way. There is a high chance that if you do not have a drinking well located several hundred feet below the surface then you have been exposed to many toxic substances that have been dumped into the ground and into our waterways for many years.
Though pollutants themselves are harmful to the environment, they usually contain nutrients such as nitrates and phosphates. The addition of these nutrients into water systems disrupts the natural balance, and ultimately leads to overgrowth. This overgrowth can clog waterways, and prevents light from reaching deep into the water, killing off life which was sustained at a deeper level. Much of this type of pollution comes from fertilizers, sewage, and organic livestock wast... ... middle of paper ... ...uman necessity. The idea of water privatization has been tossed around for years, but recently had become a reality for some in 3rd world countries.
It is scary but true. Water, one hydrogen and two oxygen, is a compound that life on Earth is completely dependent upon. A clean drinking water supply is imperative if life is going to continue. Without a supply of clean drinking water, life would cease to exist. Much of Earth’s water is contaminated with chemicals and more water is being polluted each day.
Some of the problems with chemicals getting into our water systems are that the soil can only hold so much liquid, the rest of the chemicals run off into our streams and creeks. Another way that they can get around is that if a pesticide gets sprayed in warmer weather it can evaporate into the air and away from the initial application site, which is called Volatilization. Spray drift is another way that pesticides get from one place to another. It happens by if a field happens to be sprayed and some of it can become airborne and move away from the application site. It is affected by the size of the droplets, which smaller droplets can get carried away faster that the larger droplets, the distance between the spray nozzle and the ground can really affect the drifting also.
