Salt Contamination: A Threat to Groundwater Quality

Sep 27, 2021

Access to quality water is a critical part of everyday living in this country and around the globe. Yet, salt contamination and other environmental factors continue to threaten our groundwater resources, which is where much of our usable water comes from.

Let’s take a closer look at the problem and what can be done to solve it.

What is Salt Contamination?

Salt contamination occurs when saline water makes its way into surrounding soils or our freshwater resources. While salt can often be a good thing, too much of it in areas that don’t normally have it can lead to significant problems.

For example, soil that becomes contaminated by large salt quantities may lose its permeability, or at least have its permeability altered. This then affects whatever this soil is used for, such as a leach field or for growing crops. In these two instances, a leach field with salt contamination will not be as effective and crop growth may be stunted in soils with high salinity.

Similar effects are noted when groundwater is subjected to salt contamination. High salinity groundwater makes its way into freshwater lakes, rivers, and streams. Ecosystems are disrupted along the way with plants, animals, and aquatic life all being adversely affected. Communities that rely on groundwater resources for drinking water must then go through the expensive process of desalination, or removing the excess salt from the water.

Where Does Salt Contamination Come From?

In order to solve this growing problem, it’s important to understand where salt contamination comes from. Here are the most common sources:

  • Severe drought – When freshwater aquifers are no longer filled to capacity due to drought conditions, saline water can more easily make its way in.
  • Climate change – As sea levels rise, high salinity water intrudes into our groundwater sources.
  • Increased groundwater pumping in coastal areas – Higher water demands in an area along the ocean may lead to increased groundwater pumping to meet the need, leaving behind the perfect environment for saltwater intrusion.
  • Water softeners – Salt-based residential and commercial water softeners discharge a highly concentrated salt brine into the environment during their regeneration process.
  • Industrial or food processes – Companies involved in tanning leather, manufacturing textiles, or processing certain types of food often use large volumes of saline water for their processes. This brine is often discharged into surrounding soils or freshwater sources, leading to salt contamination.

The Salt Miner: An Eco-Friendly Salt Management Solution

Quality water is a necessary part of our everyday living. And, preserving that water quality by preventing salt contamination is important in order for us to continue life as we know it. Trying to fix salt contamination after it has already occurred, however, is a very expensive endeavor.

Whenever possible, it’s cheaper and more effective to manage salt contamination at the source, rather than trying to clean up the mess it creates in the environment after the fact. This is where the Salt Miner comes in. It’s an easy add-on to any salt-based water softener or brine system and it sits between the brine source and the drain. As it ‘mines’ the salt out of the system’s wastewater, it collects it for recycling or disposal rather than dumping it down the drain.

What’s the end result of using the Salt Miner? Salt contamination of groundwater and soils is prevented in a cost-effective, environmentally friendly way. What could be better?!
