What’s is in Your Water?
Water takes a journey which puts it in contact with compounds that eventually contaminate your water supply. Water travels through man’s and nature’s long deliver process to your tap. We can look at the water cycle to get an understanding of when and where certain types of contaminants get into your tap water. The water cycle is condensation, precipitation, infiltration and run-off.
Water is a unique compound because it has the ability to change from a liquid into a gas form. It is this property that allows water to evaporate with heat or with the power of the sun. Once water is in gaseous form, it becomes lighter and travels up into the sky. Then the water gas comes in contact with other particles and it becomes water-vapour and forms clouds. This is part of the cycle is called condensation.
The water gas comes in contact with industrial contaminants such as green-house gases that are released into atmosphere because of the burning of fossil fuels. These contaminates join with the gaseous water as it forms water-vapour. When the water vapour becomes heavy it then falls to the ground.
The water vapour becomes heavier, and the water forms either rain, sleet, snow or hail, and it falls under the weight of gravity. It is because water has an ability to absorb other particles that the water vapour holds onto the contaminants. Water carries the pollution with it. Water will hold onto these contaminants until it is evaporated again. The only other way that the contaminants are removed is if the water is processed through a water filtration system.
Soil and Rock Filtration
Once water falls to the ground, water can take a number of different journeys depending upon the geological or climatic conditions of where it falls. Water has the potential to infiltrate the soil and move into the under ground water. While it moves through the soil and rocks, water will absorb both natural organic and non-organic particles into its own structure.
For example, if water infiltrate an area that suffer from salinity then it will absorb salt. The same goes for if the water infiltrate areas that have a high percentage of iron, radium, lead, fluoride, copper, to name a few, in the soil or rocks.
While water soaks through the soil and ground, it will absorb chemicals, fertilisers and other waste residues. If the water does not infiltrate the soil and does not go into the ground water supply, it will then run-off into our streams, lakes, dams, rivers and water tanks.
If the water falls in a region where the soil is all ready saturated, or the rocks don’t allow water to infiltrate, then it will run-off the ground into the our water systems. Water will absorb chemicals, fertilisers, salt, metals, pesticides, herbicides, pharmaceuticals, and waste. Water will carry organic matter, faecal matter, viruses, bacteria and dirt. Water will follow the natural flow until amount of water will make its way into your water supply.
However, if the climatic conditions are extremely cold then the water will form ice where it will remain as ice until the climate is hot enough to melt it. Once the water melts then it will then run down the mountains or melt from the ice-sheet into the sea. Water will contain the pollution that it gathered from the sky.
People source their water from a number different places; tank water from roof run-off, ground water aquifer, pump it from streams, rivers, dams or lakes, or like most people you receive water from the town water supply.
