EPA Standards Miss Many Chemicals in Drinking Water, Study SaysMore
City water in Stockholm, Stockholm County
Water Quality – TDS (ppm)
Daily Water Temperature °F
Stockholm, located in Stockholm County, SE, boasts a reputation for having relatively high standards of water quality. The city's water is sourced from the pristine Lake Mälaren, which provides fresh drinking water to the entire region. Whereas the municipal authorities ensure the ongoing treatment and monitoring of water making certain it meets domestic and international water quality standards.
Source: The water supply in Stockholm primarily comes from Lake Mälaren, which is continuously monitored for pollutants. Despite being a clean source, it is still subject to contaminants from both natural and human-made sources.
Testing: Regular testing is performed to monitor the levels of contaminants such as heavy metals, nitrates, and microbial content ensuring safety for consumption. Advanced technologies and strategies are employed to address any issues promptly.
Standards: The water quality in Stockholm adheres to strict standards set by both national regulations and the EU directives. These standards ensure the protection of public health and make certain water is palatable and safe.
Water Hardness: Stockholm's water is considered moderately hard, meaning it contains relatively high levels of calcium and magnesium. While this is not typically harmful, it can contribute to scale buildup in pipes and appliances over time.
Concerns: Despite largely meeting safety and quality standards, the water can occasionally experience quality issues such as slight discoloration, taste, or odor changes usually caused by pipe maintenance or seasonal changes.
Why Consider a Water Filter or Softener?
In conclusion, although Stockholm boasts high standards of water quality, utilizing home water filters or softeners can enhance water taste and reduce hardness, ensuring an even more reliable source of clean water for daily use.

We have developed the TDSBot, an inexpensive IOT device that monitors, in real time, the Incoming and Outgoing TDS levels, temperature, flow rate and cumulative volume of water filtered. Easy to install, it works with all water purifiers including, sediment, GAC, Carbon, Micro, Ultra, Nano and Reverse Osmosis water filters. Key benefits:
TDSBot can be installed on water purifiers from Pentair, Culligan, 3M, Brita, BWT, iSpring, and most other brands. Supports sediment, GAC, Micro, Ultra, Nano and Reverse osmosis filters. It can remotely monitor filters attached to Coffee machines, Ice makers, soda fountains, water dispensers, ovens, laundry & dish washing, car wash found at Cafes, convenient stores, healthcare facilities, hotels, offices, restaurants, colleges, schools, hydroponic systems, and many more.
