I. Which Water Sources Are Prone to Iron and Manganese Contamination?

Household water sources nowadays mainly come from two main sources: drilled wells and tap water. In addition, many businesses, production units also use surface water from rivers, lakes, ponds, canals to serve production and processing activities. These water sources are at risk of being contaminated with Iron, Manganese, and other heavy metals or impurities.

1. Drilled Wells Water

Drilled well water is one of the water sources at high risk of being contaminated with Iron and Manganese. Since drilled well water is directly taken from deep underground water veins beneath the ground, it directly contacts with geological layers containing Iron and Manganese, making it easy for these two metals to dissolve into the water.

2. Surface Water

Surface water, including river water, lake water, pond water, and canal water, also has a high risk of being contaminated with Iron and Manganese. The main reason is the erosion of soil and rocks containing Iron, Manganese into the water. In addition, industrial, agricultural, and human activities also contribute to the increase in the concentration of these two metals in surface water through uncontrolled discharge processes.

3. Tap Water

Although tap water has undergone treatment at water treatment plants, it can still be contaminated with Iron and Manganese. This can happen due to various reasons, including:

• Inadequate water treatment processes:

In the water treatment process, completely removing Iron and Manganese can be challenging if the treatment system of the plant does not achieve high efficiency or due to outdated treatment technology. Nowadays, water treatment plants often use methods such as oxidation, precipitation, and filtration to remove Iron and Manganese, but in some cases, the concentration of Iron and Manganese may still remain in the water.

• Corrosion of water pipes:

Metal water pipes, especially iron pipes, can corrode over time, leading to iron particles leaching into the water. When water passes through these pipes, Iron and Manganese from the pipes can dissolve into the water, causing contamination.

• Old water storage tanks and reservoirs

Old water storage tanks and reservoirs, especially metal tanks, can also be a source of Iron and Manganese contamination. If these tanks are not regularly cleaned and maintained, these metal particles can settle and dissolve into the water.

• Contaminated source water

The source water of water treatment plants, including river water, lake water, or groundwater, may contain Iron and Manganese. If this source water is not efficiently treated before being supplied to the water system, these metals may still remain in the water provided to households.

II. How to Identify Iron and Manganese Contaminated Water

There are several ways to identify water contaminated with Iron and Manganese by observing the following unusual characteristics:

1. Observe Color and Taste

• Iron-contaminated water often has a yellow, brown, or brick-red color when iron precipitates, with a metallic or musty odor.
• Manganese-contaminated water often has a black or gray color when Manganese precipitates, and may have a musty or other unpleasant odor.

2. Observe Sediment and Deposits

If you see red or black sediments settling at the bottom of the container after letting the water settle, this is a sign of Iron or Manganese precipitation.

Yellow, brown, or black stains on water containers, sinks, and household items are also signs of water contaminated with these metals.

3. Test Water Using Scientific Methods

If you observe any unusual points in the water, to confirm whether the water is contaminated with Iron, Manganese, or other heavy metals, use rapid test kits or send water samples to laboratories for detailed analysis and accurate determination of the concentration of these metals.

One of the addresses providing rapid test kits and water testing services with detailed component analysis is Toan A Environmental Technology Joint Stock Company with a LAB room capable of testing, ensuring compliance with ISO 17025:2017 standards, licensed and using the capability certification stamp according to current AOSC regulations.
