The Effects Of Water Pollution

Water pollution is a serious matter, and can be defined as a problem. Poor water quality is just another way of saying water pollution. Water pollution is when one or more substances build up in water to such an extent, that several problems for animals and humans develop. Rivers, lakes, oceans, and other inland waters are able to naturally clean up certain amounts of the pollution by dispersing them harmlessly.
Water pollution depends on the quantities: how much of the polluting substance is released, and how huge the volume of water it is released into. Small quantities of a toxic substance may have little impact if released into the ocean, but the same amount of this same toxic substance may have a much larger impact if pumped into a river of lake, where the quantity of clean water is too little to disperse the substance.
More than half of Earth’s surface is covered by water, about a quarter of Earth is taken up by land. As the population of Earth continues to grow, more and more people are putting an extreme amount of pressure on our planet’s water resources. The more human activity there is, the more our water quality is reduced.
Lakes, rivers and huge oceans are our main water suppliers, we classify them as “surface waters”.
Pollution that comes from a single, specific location such as a factory discharging substances from a pipe, is known as point-source pollution. As point-source pollution enters the environment the area around this source is effected and the pollution can be seen immediately. A large proportion of water pollution comes from many different dispersed sources and not just a single source. This is known as nonpoint-source pollution. Pollution from this source, infiltrates the environment from several different places all at once. Trans boundary pollution is when hundreds or even thousands of miles
