What are the problems caused by water pollution?
When discussing the issues that can arise due to water pollution, there are three major areas to consider: 1 Health: According to the United Nations, every year there are more deaths caused by polluted water than all types of violence combined, including war. Waste from humans and animals that contaminates water carries bacteria and viruses that cause the spread of diseases such as typhoid, cholera and giardia. 2 Environment: All the species in an ecosystem rely on each other in order to survive. Outside substances, such as pollutants found in wastewater, can disrupt the complicated relationships between species that an ecosystem needs in order to thrive. 3 Economy: Polluted water can have many negative effects on the economy. It directly impacts sectors such as commercial fishing, recreational businesses, tourism and even property values, all of which rely heavily on clean water. Polluted drinking water can also cause treatment costs to rise, which in turn makes the cost of drinking water rise as well.
How does industrial waste affect water quality?
Industries and industrial sites across the world are a major contributor to water pollution . Many industrial sites produce waste in the form of toxic chemicals and pollutants, and though regulated, some still do not have proper waste management systems in place. In those rare cases, industrial waste is dumped into nearby freshwater systems. When industrial waste is not treated properly (or worse, not treated at all), it can very easily pollute the freshwater systems that it comes into contact with.
