The Importance of Water Testing and Filtration

In a recent study conducted by a team of water technicians at SimpleLab, chemical levels in various water samples were tested. The research, published in the journal PLOS Water, aimed to compare the quality of water from different sources in the San Francisco Bay area. While tap water has traditionally been considered safe for consumption, recent events such as the lead contamination crisis in Flint, Michigan, have raised concerns about water safety.

The team at SimpleLab analyzed 100 samples of bottled water, 603 samples of tap water, and 111 samples of tap water filtered using a Brita filter. The results showed that most of the tested water samples met federal drinking water health standards. However, it was found that chemical levels in filtered and bottled water were similar, while tap water had elevated levels of certain chemicals, particularly trihalomethanes.

Trihalomethanes, which are formed when chlorine is used to disinfect water, were found in all three water sources. These chemicals have been associated with various health issues, including liver damage, developmental delays, and an increased risk of certain cancers. Despite the presence of these chemicals in the water, the researchers emphasize that consuming small amounts is unlikely to cause harm.

The researchers suggest that using a water filter can help reduce the levels of chemicals in tap water, improving its taste and potentially enhancing its safety for consumption. While the findings are not intended to cause alarm among consumers, the study highlights the importance of water testing and filtration in ensuring the quality of drinking water.

The study by SimpleLab provides valuable insights into the chemical composition of drinking water from different sources. The results underscore the benefits of using a filter when drinking tap water, as it can help mitigate potential health risks associated with certain chemicals. By prioritizing water testing and filtration, consumers can take proactive steps towards safeguarding their health and well-being.
