Why Salt Based Water Softeners are Bad for the Environment
A water softener is a device that aims to significantly reduce the hardness of the water circulating in your plumbing system. Generally, they come as part of a combo-package which also includes a top rated whole-house filtration system. While the filter traps dangerous contaminants, the softener prevents the appearance of limescale. Lime deposits are the natural consequence of the presence of calcium and magnesium carbonates in the water, so it’s almost impossible to avoid them but the water softener will hunt down and capture the minerals and have them replaced with sodium ions. However, salt based water softeners are said to cause harm to the environment. Learn more about this in the article below.
High treatment costs for wastewater
While a top rated whole-house filtration system will not affect the environment in any way, the same cannot be said for a salt based softener. The water softener is not good for the environment because it increases the costs for treating the wastewater. It is estimated that it costs about $0.20 to add a pound of salt to a water-softening system but it actually costs almost $5.00 to remove the chloride at the treatment plant. Generally speaking, higher salinity in wastewater can increase the treatments costs while minimizing the chance of reusing treated wastewater for industrial purposes or irrigation.
Salt-based softeners are bad for your plants
If you prefer using softened water on your indoor or outdoor plants, what you must keep in mind is that over time the plants will wither and die of thirst due to the high salinity level in the soil. The soil can also become swollen and compacted due to high concentration of salt that decreases the levels of oxygen. Once this process takes place, plants die because the roots don’t receive enough nutrients and minerals.
Softened water can affect the city-water source
Another major drawback of using a salt-based water softener is the fact that once salt reaches into the city’s waste water through normal activities such as washing clothes or showers, it will irrigate the agriculture and parks. As a result, the soil gets compacted and loses important minerals and nutrients. The high salt concentration will not only cause the plants to die but it also prevent other new plants from growing in the soil that has been contaminated.
Softened water can harm the aquatic environment
In some places around the world, the salt that comes from softened water is discharged into the ocean and this is not only expensive but also extremely harmful for the aquatic environment. In other places, treated waste water is discharged into the rivers or lakes and this can be bad for the plants and fish. It is therefore recommended to avoid using a salt-based water softener and use a water filter a newer water softener that is safe for our health and for the environment as well.
