Arsenic is naturally found in rocks and soil. Hence it can easily find its way into groundwater. As per numerous studies, a lot of states in the US are prone to arsenic contamination. Arsenic doesn’t have a taste or smell on its own hence it can’t be detected in the dissolved state.

Testing water for Arsenic is not mandatory for good private owners. However, once you know the health damages arsenic can cause, it is essential to test water for arsenic.

It causes life-long irreversible health conditions that make it important to have water that isn’t arsenic contaminated. The only way to test the presence of arsenic in water is through a lab test.

What is Arsenic?

Arsenic is an element that is widely available naturally. As per World Health Organisation, arsenic is already present in groundwater at high levels across a lot of countries. Apart from its natural origin in the Earth’s crust, it finds its way into the air, soil, and water through the increasing mining activities, power plants, pesticides, and lumber treated with arsenic.

It is found in two forms: organic and inorganic. The organic form is arsenic which contains carbon. It is considered highly toxic in its inorganic state and causes severe health problems. Arsenic found in drinking water is already a growing concern across the globe.

How Does Arsenic become a problem

Arsenic is used widely in agricultural practices, mining, and power plants and occurs naturally in the environment. Due to this, it has already contaminated water, soil, and air. Arsenic used in pesticides has resulted in rice, fish, vegetables containing traces of arsenic. Water used for farming also contributes to arsenic levels being high in food.

Groundwater gets contaminated by arsenic when naturally occurring arsenic contact water. Another way drinking groundwater gets contaminated is the pesticides containing arsenic seeping into the Earth’s crust.

In Taiwan, it has infected people with the Blackfoot disease. Extreme cases of arsenic exposure have caused deaths too.
