Water quality plays a crucial role in long-term health, yet many households and communities rely on water sources with elevated mineral content. One common question that arises is whether 700–800 TDS water is safe for everyday consumption. To answer this, it is important to understand what TDS means, how it affects drinking water quality, and when treatment becomes necessary.
What Is TDS?
Before evaluating safety, let’s address a fundamental question: What is TDS?
TDS stands for Total Dissolved Solids. It represents the total concentration of dissolved inorganic salts and organic matter present in water. These dissolved solids typically include calcium, magnesium, sodium, potassium, chlorides, sulfates, and bicarbonates.
TDS in drinking water is measured in milligrams per liter (mg/L) or parts per million (ppm). While TDS itself is not a direct health parameter, it serves as an important indicator of water taste, usability, and overall quality.
Drinking Water TDS Limits: What Do Standards Say?
Various international and national guidelines define acceptable drinking water TDS limits:
- Up to 300 mg/L: Excellent quality
- 300–600 mg/L: Good quality
- 600–900 mg/L: Fair quality
- 900–1200 mg/L: Poor quality
- Above 1200 mg/L: Unacceptable for drinking
Based on these benchmarks, water in the 700–800 TDS water range falls into the “fair” category. This means it is not immediately harmful for most healthy individuals, but it may not be ideal for long-term daily consumption without treatment.
Is 700 TDS Water Safe to Drink Daily?
So, is 700 TDS water safe to drink? The answer depends on several factors.
From a health perspective, water with 700–800 mg/L TDS does not usually contain toxic substances solely because of its TDS level. However, higher TDS often indicates increased concentrations of certain salts, which can have indirect effects over time.
Potential concerns include:
- Taste and Palatability – High TDS water often tastes salty, bitter, or metallic, discouraging adequate hydration.
- Digestive Sensitivity – Some individuals may experience stomach discomfort or laxative effects due to high sulfate or magnesium content.
- Kidney and Heart Health – People with kidney disease, hypertension, or those on low-sodium diets may be affected by excess sodium or mineral intake.
- Scaling and Residue – High TDS contributes to scaling in kettles, pipes, and appliances, indicating mineral overload.
While occasional consumption may not be harmful, regular intake of 700–800 TDS water is generally not recommended for infants, elderly individuals, or people with underlying health conditions.
Why High TDS Should Not Be Ignored?
Although TDS itself is not a contaminant, elevated TDS in drinking water can signal the presence of undesirable substances such as:
- Excess sodium from groundwater or seawater intrusion
- High hardness due to calcium and magnesium
- Industrial or agricultural runoff is increasing salt levels
Over time, consistent consumption of high-TDS water may place unnecessary strain on the body’s filtration systems, especially the kidneys.
When Should Water Treatment Be Considered?
If your water supply consistently measures between 700 and 800 mg/L TDS, treatment should be considered—especially for daily drinking purposes.
Advanced water treatment technologies can selectively reduce excess dissolved solids while retaining essential minerals. The goal is not to strip water completely, but to balance mineral content for safety, taste, and long-term health.
How Ion Exchange Helps Improve Drinking Water Quality?
Ion Exchange has decades of experience in delivering reliable and efficient drinking water treatment solutions for households, communities, and industries. Our systems are designed to address high TDS challenges without compromising water safety or sustainability.
Ion Exchange solutions offer:
Advanced Drinking Water Treatment Technologies by Ion Exchange
It is a cutting-edge technology used to remove the majority of contaminants from water by applying pressure to force water through a semi-permeable membrane. This membrane allows the passage of water molecules while blocking dissolved salts, organics, bacteria, and pyrogens. The high-pressure pump increases pressure on the salt side, pushing water across the RO membrane and leaving most dissolved salts behind in the reject stream. The treated water typically has 95% to 99% of dissolved salts removed.
- Ultraviolet (UV) Technology
It offers an effective method for eliminating biological contaminants. These purifiers guard against water-borne viruses, bacteria, and microorganisms such as Giardia and Cryptosporidium. Exposure to UV radiation within the flow chamber purifies harmful microbiological impurities.
- High Recovery RO (HRR) Technology
The innovative High Recovery RO (HRR) process, featuring the Water Saver Cartridge (WSC), continuously sweeps away salts and kills microbes, allowing operation at high recovery levels. This process achieves up to 70% recovery from a single RO membrane, three times higher than conventional systems, and saves over 80% of water, making it eco-friendly with a high shelf life for treated water.
- Electrolytic Sanitizing System (ESS) Technology
Conventional UV systems can suffer from slime buildup, bacterial growth, voltage fluctuation, and quartz scaling, leading to poor disinfection. The patented ESS technology by ZeroB ensures complete microbial kill, overcoming these drawbacks and preventing water recontamination.
- Resin Technology
Ion exchange resins play a crucial role in various separation, purification, and decontamination processes. Ion Exchange manufactures a range of resins, including poly-iodinated and iron-specific resins, which eliminate microbial contaminants and reduce iron levels to safe drinking standards (less than 0.3 ppm).
Ideal TDS Range for Daily Drinking
For most people, the ideal TDS in drinking water ranges between 100 and 300 mg/L. This range offers a good balance of essential minerals, pleasant taste, and safety for long-term consumption.
Water below this range may lack minerals, while water consistently above 600 mg/L may require treatment for daily use.
Conclusion
To summarize, 700–800 TDS water is not immediately toxic, but it falls outside the ideal range for daily drinking. While it may be safe for short-term or occasional use, long-term consumption can affect taste, comfort, and health—especially for vulnerable individuals.
Understanding what TDS is, monitoring TDS in drinking water, and adhering to recommended drinking water TDS limits are essential steps toward better health and water safety.
