Let Our Water Testing Company Provide Resources You Can Trust

In addition to being better than bottled water, water filtration systems can assist with arsenic removal from New England waters.

In New England, many of us get our water from a bedrock well for home water use. Wells that have been drilled in bedrock have the potential to contain the element arsenic. Because it is odorless and tasteless, the only way to know the amount of arsenic in your water supply is to have water testing services performed.

There is field testing equipment that exists but using a certified lab such as Granite State Analytical will produce the best results. Arsenic that gets into your home water supply usually exists in two forms, arsenite and arsenate. 

Arsenite is Arsenic III (As III) and arsenate is Arsenic V (As V).

Reducing As III is harder than reducing As V. Numerous studies have shown the ratio of arsenic species can fluctuate due to varying ground water recharge. Other fluctuation contributors include pH and bore hole contact time, and fluctuations of As III and As V happen very consistently. Testing for As III and As V independently is not required. Always install an oxidizing filter to see if As V is present. This approach ensures As III does not impact the longevity of the adsorption medias.

Incorporate an oxidizer that converts As III to As V for better removal and consistency. Testing for each is pointless if the treatment system contains an oxidizer. Many times, an oxidizer can serve multiple purposes, such as odor removal and iron reduction.
