What are PFAS?
PFAS Explained
According to the Environmental Protection Agency, Per- and poly-fluoroalkyl substances, or PFAS, are a family of thousands of widely used, long-lasting chemicals that have become ubiquitous in our environment. Their slow breakdown means they are found in water, air, soil, and even in the blood of humans and animals worldwide. Unfortunately, scientific studies have shown that exposure to some PFAS may be linked to harmful health effects in both humans and animals. With their presence in so many consumer, commercial, and industrial products, it can be challenging to study and assess the potential risks of these chemicals to human health and the environment. Despite these challenges, at Water Doctor of Washington, we are committed to helping you combat PFAS contamination and achieve the peace of mind that comes with knowing your water is safe and clean.

Different Types of Water
In a typical home, there are three types of water - raw water, working water, and drinking water. At Water Doctor of Washington, we understand the importance of each of these stages and are here to help. Our expert water treatment services can address contamination at every stage of the water supply, ensuring that you and your family have access to pure, refreshing, and safe water in your home.

Raw Water
Raw water is the untreated water that comes into the home through the main water line. This water can contain a range of contaminants, including PFAS, which can pose health risks to those who consume it. It's important to treat raw water to remove these contaminants before it enters the working and drinking water supply.

Working Water
Working water is the water that is used for everyday tasks, such as washing clothes, dishes, and taking showers. While it does not need to be treated to the same extent as raw water, it should still be filtered to remove impurities that can affect the taste and quality of the water.

Drinking Water
Drinking water is the water that we consume directly. The removal of PFAS from drinking water is of utmost importance, as exposure to these chemicals has been linked to a range of health risks. At Water Doctor of Washington, we offer expert water treatment services that can remove PFAS and other contaminants from raw and drinking water, ensuring that your family has access to clean, safe water for all their needs.
