Water Quality Issues

1. Source: Queluz's water comes from a combination of surface and groundwater sources. Due to its geographical location and climate, seasonal changes can impact the composition and quality of these water sources.

4. Water Hardness: Queluz is known for its hard water, characterized by high concentrations of calcium and magnesium ions. While it is not harmful to health, it can cause scaling in pipes and affect the efficiency of soaps and detergents.

Recommendations

To address some of the water quality concerns, it is advisable for residents in Queluz to consider using water filters or softeners. Water Filters: Employing activated carbon filters can help reduce chlorine taste and eliminate some chemical contaminants. Water Softeners: These devices can mitigate the effects of hard water, extending the lifespan of household appliances and improving cleaning efficiency. Engaging in these practices can contribute to improved water quality at home, offering peace of mind to residents.
