Tap water quality in A Coruña, Galicia? Is it safe to drink?

Opening:

A Coruna, located in the picturesque region of Galicia, Spain, is a city cherished for its charming landscapes and vibrant lifestyle. While the area boasts of natural beauty, one critical aspect often under scrutiny is its water quality. Residents and visitors alike are keen to understand the safety and reliability of the water flowing through the city's taps.

Water Quality Issues

Source:

The water that supplies A Coruna is primarily sourced from local rivers and reservoirs, ensuring a steady demand for residential and industrial use. However, the proximity to agricultural lands means there can be potential runoff, adding to water quality challenges that need vigilant monitoring.

Testing:

Regular testing is conducted by local authorities to monitor water quality parameters and ensure compliance with safety standards. These tests check a range of factors including microbial presence, chemical contaminants, and physical characteristics of the water.

Standards:

The local water management complies with both national and European Union standards, striving to maintain quality benchmarks that ensure safe consumption for all residents and visitors.

Water Hardness:

Water hardness is a common issue in A Coruna, primarily due to the mineral content in the local water sources. This can affect household chores, appliance longevity, and even skin and hair health for sensitive individuals.

Concerns:

  1. Microbial Contamination: There is always a risk of microbial contamination, necessitating rigorous testing to prevent health risks.
  2. Chemical Contaminants: Runoff from industrial and agricultural activities may introduce unwanted chemicals into the water supply.
  3. Heavy Metals: Traces of heavy metals, although rare, can sometimes be found, emphasizing the need for continuous monitoring.

Encourage Using Water Filters/Softeners

To tackle these challenges, it is advisable for households to consider installing water filters and softeners. These devices can significantly enhance water quality by removing impurities and adjusting mineral content to create a healthier home environment. Adopting such solutions not only ensures the well-being of residents but also contributes to the longevity of plumbing and household appliances. Investing in quality water filtration and softening systems is a proactive step toward a healthier lifestyle in A Coruna.

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.
