How to remove arsenic from drinking water?
Collect your water sample from the tap that you drink from the most often: for most households that is the kitchen sink. Follow the directions for collecting a water sample carefully to be sure that your test results are accurate. Mail or bring the sample back to the lab.
How much does it cost to test for arsenic in water?

How to remove arsenic from water?
Unfortunately, you need more than a standard carbon filter in order to remove arsenic from your water. Instead, a reverse osmosis system is recommended. This process forces your water through a semi-permeable membrane. It then filters out different contaminants using pressure and pushes the clean and pure water through to your tap. Reverse osmosis systems can be used to remove pesticides and other harmful chemicals along with arsenic. If you do decide to have a reverse osmosis system installed, it’s important to maintain the system regularly to ensure that it continues filtering your water properly.
How does arsenic affect water?
Arsenic can contaminate your drinking water through a number of different methods. Many industries in the United States release hundreds of thousands of pounds of this dangerous element into the air each year. Once released into the air, it can remain in the environment for years. When mixed with rain and snow, the arsenic settles into the ground. Over time, it filters through the soil and bedrock, where it comes in contact with the water that flows through your tap and into your glass.
What is the best way to test for arsenic in water?
The most thorough, preferred testing option is to use a private laboratory or public health service, preferably one that’s state-certified, to carry out a specific well water test. A laboratory can provide you with all the information you need to know about your arsenic-contaminated water.
