Tap water quality in Paço de Arcos, Distrito de Lisboa? Is it safe to drink?

Overview

The water quality in Paco de Arcos, a picturesque town in the Distrito de Lisboa, Portugal, plays a crucial role in both residential and commercial settings. Ensuring clean and safe water is of utmost importance to promote a healthy lifestyle for its residents. Water supplied in this region comes from municipal sources that are subject to stringent regulations to ensure safety and quality.

Water Quality Issues

  1. Source: The primary water source for Paco de Arcos originates from regional reservoirs, treated to remove impurities and contaminants before distribution. This process aims to comply with national and EU water safety standards.
  2. Testing: Regular water testing is conducted to monitor various parameters, including microbial content, chemical concentrations, and physical characteristics, ensuring that the water remains safe and potable.
  3. Standards: Water quality in Paco de Arcos adheres to EU Drinking Water Directive standards, ensuring it is suitable for consumption. Compliance with these standards is verified through routine testing and monitoring by local authorities.
  4. Water Hardness: Water hardness in this region is an area of concern for many residents. Hard water, caused by high levels of calcium and magnesium, can lead to scaling on appliances and reduce the efficacy of soaps and detergents.
  5. Concerns: Some concerns remain regarding occasional increases in specific contaminants such as nitrates and microplastics, primarily from agricultural runoff and industrial activities, necessitating ongoing surveillance and management.

Encouragement for Using Water Filters/Softeners

Using water filters and softeners can be highly beneficial in Paco de Arcos. Filters can reduce the presence of unwanted substances, enhancing taste and safety for drinking water. For households facing hard water challenges, softeners can play a pivotal role in preventing limescale buildup in plumbing and appliances, leading to increased longevity and efficiency. Investing in these systems provides peace of mind, ensuring the water you use daily meets your health standards and improves your overall quality of life.

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.
