Tap water quality in Córdoba, Andalusia? Is it safe to drink?

Opening

Cordoba, located in the heart of Andalusia, Spain, is a city renowned for its historical and cultural significance. Besides its picturesque streets and monuments, the city is also known for its efforts to maintain a sustainable and clean environment. One crucial aspect of environmental sustainability is ensuring good water quality for its residents and visitors.

Water Quality Issues

Understanding the water quality in Cordoba requires examining a few key aspects:

  1. Source: The primary source of water in Cordoba is from the river Guadalquivir and several reservoirs. These sources are crucial for providing the city with adequate water supply throughout the year.
  2. Testing: Regular testing of water quality is conducted to ensure that the water meets health standards. This involves analyzing the microbial, chemical, and physical properties of the water.
  3. Standards: The water quality in Cordoba must comply with both European Union directives and Spanish national standards. These regulations are in place to ensure that the water is safe for drinking and other uses.
  4. Water Hardness: Cordoba's water is classified as moderately hard due to high concentrations of calcium and magnesium. This is a common characteristic in many parts of Andalusia.
  5. Concerns: While the water quality is generally good, there are occasional concerns regarding contaminants such as nitrates and chlorine by-products, which are monitored closely.

Encouragement to Use Water Filters/Softeners

Given the moderate hardness and potential contamination issues, residents and visitors in Cordoba are encouraged to consider using water filters and softeners. Water filters can effectively remove impurities such as chlorine, heavy metals, and other contaminants, providing safer and better-tasting water. Water softeners are beneficial for reducing the hardness of water, preventing scale buildup in plumbing, and improving the efficiency of soap and detergents. By using these systems, individuals can contribute to better personal health and a sustainable environment.

What do we do? How do we help?

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:

  • Know the incoming and filtered water quality in real time.
  • Know the volume of water filtered by day, week, month and total.
  • Know in advance when to change filter cartridges. Too often we tend to realize that they need changing after the water purifier has stopped working or worse, when the water smells bad.
  • Change filters only when needed. Sometimes filters perform longer than their standard life due to better incoming water or lower usage. Reduce waste and save money.
  • Quality data collected is aggregated to show real time water quality data to all the community.

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.

* A definition specific to a few codes is that “Safe drinking water” means water that meets all primary and secondary drinking water standards. Drinking water standards are set based on potential health impacts and also take into account the cost to meet the drinking water standard. Also, the U.S. Environmental Protection Agency (EPA) defines drinking water as safe when humans can drink it with low risk of immediate or long-term harm to your health. Although there may be health risks associated with certain contaminants found in drinking water not all contaminants are necessarily harmful.
