According to the World Health Organization, the normal TDS level of drinking water should be between 50 and 200 ppm. While TDS levels above 200 ppm are not considered harmful, they may indicate that the water is of poor quality. In this blog post, we will explore what TDS levels in drinking water mean and how they can affect your health.
Total Dissolved Solids (TDS) is a measure of the combined content of all inorganic and organic substances present in water in molecular, ionized or micro-granular (colloidal solids) suspended form.
Inorganic substances include minerals, salts, metals, cations or anions dissolved in water. Organic substances include plant material, animal matter, bacteria, viruses, detritus from decomposing organic matter etc. TDS is measured by evaporating a known volume of filtered water and weighing the residues left behind.
The normal TDS level of drinking water is between 50 – 200 ppm. tap waters with TDS levels above 500 ppm are not recommended for drinking.
While the acceptable level of TDS in drinking water varies depending on who you ask, the EPA has set the maximum contaminant level goal for TDS at 500 mg/L. This means that they believe that water with a TDS level below 500 mg/L is safe for human consumption.
However, just because the EPA has set this goal doesn’t mean that all water with a TDS level below 500 mg/L is necessarily safe to drink. In fact, some studies have shown that water with a high TDS level can actually be beneficial to your health.
So, what is the normal TDS level in drinking water? That’s a difficult question to answer because there is no “normal” level of TDS in drinking water. It all depends on where your water comes from and what contaminants are present in it.
If you’re concerned about the TDS level in your drinking water, the best thing to do is have it tested by a certified lab. This way, you’ll know for sure what’s in your water and whether or not it’s safe to drink.
TDS levels in drinking water are an important indicator of water quality. High TDS levels can be an indication of pollution or contamination, while low TDS levels can indicate a lack of minerals in the water. Maintaining normal TDS levels is important for both human health and the environment.
Humans need a certain amount of minerals in their diet, and water is one of the best sources of minerals. Drinking water with high TDS levels can help to ensure that people are getting the minerals they need. In addition, high TDS levels can provide some protection against diseases such as diarrhea.
The environment also benefits from normal TDS levels in drinking water. High TDS levels can lead to eutrophication, which is when lakes and rivers become overloaded with nutrients and start to experience unhealthy algae growth. This can create problems for fish, plants, and other aquatic life. Normal TDS levels help to prevent eutrophication and maintain a healthy aquatic ecosystem.
TDS levels in water can be increased or decreased depending on the intended purpose of the water. If higher TDS levels are desired, reverse osmosis filtration or distillation can be used to purify water. These processes remove impurities and dissolve minerals, leaving behind only pure water. To decrease TDS levels, ion exchange is typically used. This process exchanges sodium ions for dissolved minerals, effectively lowering the overall mineral content of the water.
The normal TDS of drinking water varies depending on the location, but is typically between 50 and 500 ppm. While there is no set standard for what is considered “normal” TDS, most experts agree that levels below 500 ppm are generally safe for human consumption. If your water has a TDS level above 500 ppm, it is recommended that you have it tested by a professional to ensure that it is safe to drink.
