What is groundwater? Is groundwater clean?

In modern society, the development of tap water has solved the need for domestic water of almost all people. The well image is also not as popular as before. However, the importance of groundwater in life, activities and production still play a very important role. Together Ocany learn interesting things related to groundwater Please!

What is the concept of groundwater?

We can imagine that below the ground there are many layers of rock and sediment that intertwine to create hollow spaces. These empty spaces are the perfect place to groundwater resides. So that means, Groundwater is the amount of water that is stored deep underground and stored in the hollow spaces in the soil.

Conditions for formation groundwater it takes quite a while. The normal groundwater formation cycle will be rainwater infiltrating into the ground, passing through the rock layers and forming groundwater in between the gaps of the sediment layers.

Groundwater flow is underground water

Groundwater flow is underground water

However, the amount of underground water does not always “choose” the way to become groundwater, but it can move towards rivers and oceans to become a source of water on the ground.

The importance of groundwater

The quantity and quality of groundwater will vary where they form. In general, wherever it is groundwater still plays a very important role in human life and activities, including:

  • The source of raw materials to make drinking water for humans
  • Supply of water for irrigation for crops and livestock
  • Water source sustains life for plants and animals on Earth
  • Source of water for surface water such as rivers, lakes, and oceans
  • Groundwater sources contribute to stabilizing river flows in rivers.
  • Fix the top layer of soil and rock to avoid landslides

Accurate ways to detect groundwater

To find circuit Groundwater It’s no longer a difficult thing, modern and manual ways can be discovered geyser underground.

Accurate ways to detect groundwater

Accurate ways to detect groundwater

Craft method #1: Use coins

Take 10 coins and string them together with string. After preparing the tool, you tie the rope to your wrist and drag the coin on the ground. When approaching groundwaterthe coin tends to be pulled towards the watercourse.

Craft method #2: Use an iron bar

This way you use 2 small L-shaped iron bars, about 50cm long. Then, hook 2 iron bars on the index finger so that the iron bar is balanced. When approaching the water circuit, the iron rod will move gradually to adjust the direction to the water circuit. When it meets the right water circuit, the iron rod will stand still, no longer moving.

Manually identifying groundwater with iron rods is quite accurate

Craft #3: Use a clock, thread and gravel

Tie the watch to a long thread. Then, you wind the thread in your hand, when you move near the geyser, the watch will rotate. Place the pebbles in the palm of the hand that is tying the watch.

When the clock stops rotating, you count the number of pebbles in your hand again. Each tablet will correspond to 1m, how many tablets in hand corresponds to geyser how deep.

Modern way: Groundwater Detector

Applying modern technology, detector groundwater was born as a perfect solution, to solve the need to find underground water sources.

Underground water detectors have many outstanding advantages

Underground water detectors have many outstanding advantages

Detector equipment groundwater has advantages such as:

  • Determine the depth and width of geyser Exactly. From there, experts can easily analyze aquifers, holes or underground flows.
  • Check the water flow to easily budget well drilling materials.
  • Easily detect water circuit even at a depth of 200m.
  • Save time and bring high efficiency.

Is groundwater clean?

Nowadays, people often hear about bottled water products produced from groundwater. The quality of treated water is very rich in minerals, completely free of impurities harmful to health.

However, the selection of input groundwater sources for water production is extremely strict. Because at present, groundwater sources are gradually being seriously polluted due to human activities such as:

  • Excess agrochemicals
  • Garbage and wastewater discharged directly into the environment
  • Waste from industrial zones
  • Medical waste

From these reasons, groundwater is gradually being degraded.invade” by dangerous impurities such as manganese, aluminum, copper, mercury, carbon dioxide, H2S acid, suspended solids, etc.

Groundwater is not suitable for direct drinking

Groundwater is not suitable for direct drinking

In short, groundwater is not really as clean as we think. When mining groundwater To make daily drinking water, you need to check the water quality and have a method to filter out harmful impurities remaining in the water.

Find the difference between groundwater and natural water

Evaluation Criteria Groundwater Natural water
Temperature Relatively stable – Groundwater usually located deep underground, so it is not affected by the change of air on the ground Seasonal Changes – Directly affected by terrestrial atmospheric changes
Total suspended solids (TSS) Low content, almost no High concentration, seasonal changes
Soluble mineral content Relatively stable and contains more minerals than natural water Varies according to soil and rainwater quality
Fe2+ ​​and Mn2+ . content Usually found in water Only found in water on the bottom of rivers, lakes, and ponds
Dissolved CO2 High concentration Do not have
Dissolved O2 gas Do not have Saturation
NH3 . gas Usually yes When the water is polluted
H2S . gas Usually yes Do not have
Microorganism Certain microorganisms are caused by iron Microbial diversity because of high nutritional content

Numbers condemning today’s groundwater pollution

According to a report from Under the General Department of Environment, groundwater is currently facing serious pollution. Especially in densely populated cities like Ho Chi Minh City. Ho Chi Minh and Hanoi.

Heavy pollution of groundwater

Heavy pollution of groundwater

The analysis results show that the quality of groundwater is no longer as clean as before. Most contain high levels of heavy metals and harmful impurities, such as iron, arsenic, ammonia, organic matter, etc.

Simple ways to join hands to deal with groundwater pollution

Most of the causes of pollution groundwater all come from humans. Therefore, the way to solve “root” is to change consciousness, educate the community on how to effectively treat and protect water sources. Through some daily activities such as:

Simple ways to join hands to deal with groundwater pollution

Simple ways to join hands to deal with groundwater pollution

  • Limit the use and storage of hazardous chemicals in the home
  • Do not throw waste, chemicals, medical drugs indiscriminately down the drain.
  • Reduce the amount of pesticides and pesticides in cultivation. Should switch to fertilizers of natural origin.
  • Regularly inspect and maintain the septic tank annually.
  • Use a water purifier or a total filtration system to treat pollutants in well water, tap water, etc.

Here is the information about groundwater and the importance of groundwater in our lives. Understanding the value of natural resources and knowing how to use them effectively is the solution to protect lives and protect children’s future. Hope you will find useful information in this article!
