Window Replacement Pollution Water is imperative to life. When our rivers, streams, lakes, groundwater, and oceans get polluted, it further cuts down the already limited amount we have available to share among us on this planet. This piece goes in depth on water pollution causes and solutions to hopefully inspire you to do your part to preserve this precious resource. What is Water Pollution?
Share Primary Causes of Water Pollution Water pollution is the contamination of water bodies including rivers, oceans, lakes, streams, aquifers, and groundwater. It occurs when foreign harmful materials like chemicals, waste matter, or contaminated substances are directly or indirectly discharged into water bodies.
Any alterations in the chemical, physical, or biological water properties qualify as water pollution. It is usually a requirement for any harmful substances or compounds to undergo treatment before they are discharged into water. Human activities are the primary contributors to the introduction of these foreign harmful materials.
Water is the second most polluted environmental resource after air pollution. Here is a list of the main causes of water pollution. Industrial Wastes Industrial and manufacturing wastes are the biggest causal agents of water pollution.
The manufacturing and industrial process mostly releases scores of chemical compounds and waste products that end up in waters. Industries emit gaseous waste of sulfur dioxide which then chemically reacts with water molecules and oxygen in the atmosphere to form sulfuric acid.
Likewise, dry sulfur compound depositions generated from industrial gasses Causes of water population waste processes frequently deposits in water bodies. Lead and mercury are examples of some of the heavy metallic substances that normally find a way to water bodies.
Fertilizers contain high levels of nitrates and phosphates and are frequently washed from farmlands adjacent to water bodies. They can cause eutrophication, which can severely damage aquatic environments. Detergents, hydrocarbons, and other chemical compounds: Detergents, solvents, petroleum hydrocarbons, chlorinated solvents, disinfectants, food processing wastes, and other chemical waste byproducts from industries are as well water contaminants that commonly end up in water sources.
Oil Spill Oil is a major water pollutant. Routine shipping, sea port operations, and oil refining at the seas have led to water pollution through oil dumping and spillage.
Once the oil spills in the water, it makes a thick layer on the surface of the water as it is insoluble in water. As a result, oil spills can extensively harm and kill a marine life because it cuts the supply of dissolved oxygen and prevents light from penetrating into the water.
Dissolve oxygen is essential for the survival of aquatic organisms and sunlight is a requisite for photosynthesis. A good example is the BP oil spill that killed thousands of marine animal species like birds, fish, turtles, and sea otters.
Sewage and Waste Water On a daily basis, sewages and wastewater are discharged into surface waters. Everyday human activities demand laundry, use of the toilet, and taking shower among other domestic water uses. All these necessities finally lead to waste and sewage water. In developed worlds, the water is channeled through a sewer system to a central waste water collection point where the water is cleaned and treated then discharged into water bodies such as rivers, lakes, and oceans.
As much as the water is treated and cleaned, it cannot be the same as fresh water. In some developing worlds with poor waste water management systems, waste water, and sewages are not treated or cleaned. They are directly discharged into the sea or water bodies.
As a result, it contaminates water bodies and threatens the survival of aquatic life or results to spread of waterborne diseases. Lake, Ocean, and Marine Dumping People sometimes dump material waste into water resources including rivers, lakes, canals, and oceans.
Examples include food waste, paper waste, rubber, glass, metallic, and plastic waste. Depositing these foreign materials into the water leads to water pollution as they have the capacity to make physical and chemical changes to the water such as discoloration or temperature changes.
Dumping of material wastes into water also modifies some of the naturally occurring chemical and substances.We also fight for policies and practices that ensure a safe and sufficient water supply through efficiency, pollution controls, better management, and .
Water pollution is the leading worldwide cause of death and disease, e.g. due to water-borne diseases. Water pollution can be grouped into surface water pollution. Marine pollution and nutrient pollution are subsets of water pollution.
Sources of water pollution are either point sources and non-point sources. Nutrient pollution, caused by excess nitrogen and phosphorus in water or air, is the number-one threat to water quality worldwide and can cause algal blooms, a toxic soup of blue-green algae that.
Other causes of water pollution. Apart from the industrial causes of water pollution, as we saw on the previous page, here are some more: Sewage and waste water Every day, we cook, do laundry, flush the toilet, wash our cars, shower and do many things that use water. May 13, · When? Water pollution started roughly around the time humans established permanent agricultural settlements - on the order of 8, to 10, BCE.
Why? Because once a population settles - and continues to crap and to die - in one place, the accumu. The causes of water pollution.
