Arsenic Mine Tailings and Health in Grand Rapids, Michigan

Arsenic is a substance found in the environment

Arsenic is a naturally occurring element found in soil, rocks, water, and air. In Michigan, including the Grand Rapids area, arsenic can be present in natural geology and in certain industrial or mining-related materials.

Arsenic occurs naturally in crushed rock and mine tailings

Arsenic is often found near gold and other metal deposits. During mining, rock is crushed and processed, and the leftover waste is called mine tailings. These mine tailings:

  • Often look like fine clay, silt, or sand
  • Can contain elevated levels of arsenic and other metals
  • May be left in piles or used historically as fill on nearby land

While Grand Rapids itself is not a major gold-mining center, many communities across Michigan have a history of mining activities. Fill dirt or construction material brought into the Grand Rapids area from other parts of the state may sometimes include soil or tailings from old mine sites.

Because Grand Rapids has a large and growing metro population and ongoing development, understanding potential arsenic exposure from soil, fill, and dust is important for local families, builders, and property owners.

Arsenic in Michigan and the Grand Rapids Area

How people may encounter arsenic

Across Michigan, including West Michigan and Kent County, small amounts of arsenic are commonly found in:

  • Natural soil and dust
  • Certain private well water sources
  • Some foods (especially rice, seafood, and some juices)
  • Industrial or mining-related materials (such as mine tailings)

Arsenic usually enters the body through:

  • Swallowing (ingestion) – in food, water, or soil/dust on hands and objects
  • Breathing (inhalation) – when arsenic-containing dust is in the air

Arsenic is not well absorbed through the skin, so touching soil that contains arsenic is usually less of a concern than swallowing or breathing it in.

In Grand Rapids, additional exposure could occur if:

  • Soil or fill used on a property contains old mine tailings from elsewhere in Michigan
  • Dust from contaminated soil is tracked into the home
  • Children play in bare dirt that contains mine tailings or contaminated fill

Cold Michigan winters and windy fall/spring seasons can also increase dust problems when soil is dry and vegetation is sparse, which may increase the chance of breathing in or swallowing contaminated dust.

Health Effects of Arsenic Exposure

Arsenic is a well-known poison, but its health effects depend on:

  • The form of arsenic (organic vs inorganic; inorganic is more harmful)
  • The amount taken into the body
  • How often and how long exposure occurs

Large, short-term exposures

Taking in a large amount of arsenic over a short time (acute exposure) can cause severe symptoms, such as:

  • Stomach pain and cramping
  • Nausea and vomiting
  • Diarrhea
  • Damage to blood cells and nerves
  • Irregular heartbeat
  • In extreme cases, death

This type of exposure is uncommon in typical residential settings but can occur with highly contaminated water, accidental ingestion of industrial products, or severe contamination.

Medium, repeated exposures over time

Moderate levels of arsenic taken in repeatedly over months or years (chronic exposure) may cause:

  • Skin changes (darkening, thickening, or small spots on hands and feet)
  • Numbness or tingling in hands and feet
  • Fatigue and weakness
  • Damage to major organs such as the liver, kidneys, heart, and lungs
  • Increased risk of certain cancers, including:
    • Skin cancer
    • Bladder cancer
    • Lung cancer

Small amounts over long periods

Some people may take in small amounts of arsenic over long periods without obvious symptoms. However, even low-level exposure may still increase long-term health risks, especially when combined with other risk factors such as smoking or pre-existing heart or lung disease, which are common concerns in Michigan’s adult population.

Arsenic in Mine Tailings: Why Young Children Are at Higher Risk

In areas where mine tailings are present in soil or fill, people can be exposed to extra arsenic from:

  • Swallowing soil or dust on hands, toys, or food
  • Breathing in fine dust when it is windy, dry, or during construction or yard work

Young children in Grand Rapids and throughout Michigan are at higher risk because:

  • They often crawl, play on the ground, and put their hands or toys in their mouths
  • They can swallow more soil and dust compared with adults
  • Their bodies are still developing, making them more sensitive to toxins

Children and adults who live near areas containing mine tailings or contaminated soil are more likely to be exposed if precautions are not taken.

Preventing Exposure to Arsenic in Mine Tailings and Contaminated Soil

If you live in or near Grand Rapids and are concerned that your property may contain mine tailings or contaminated fill, there are practical steps to reduce arsenic exposure.

Reduce contact with contaminated soil and dust

  • Limit bare soil:
    • Cover bare ground with grass, mulch, or other ground cover
    • Use clean topsoil for yards and play areas
  • Control dust indoors:
    • Wet-mop floors and wipe surfaces regularly
    • Use a vacuum with a HEPA filter, especially during dry winter months when windows are closed and dust accumulates
  • Remove shoes at the door to avoid tracking contaminated soil into your home.

Protect young children

  • Do not allow young children to play directly in soil that may contain mine tailings or unknown fill.
  • Provide sandboxes or raised play areas filled with clean sand or soil.
  • Wash children’s hands frequently, especially:
    • Before eating
    • After outdoor play
  • Wash toys that have been used outside, especially those that go into children’s mouths.

Safer gardening and local food practices

Grand Rapids residents who garden at home or in community gardens should:

  • Use clean soil for raised beds if you are unsure about your existing soil quality.
  • Add clean compost or topsoil to dilute potential contaminants.
  • Always wash homegrown fruits and vegetables thoroughly with clean water before eating or cooking.
  • Peel root vegetables (like carrots or beets) if soil contamination is a concern.

Water, swimming, and recreation

  • If you use a private well in Kent County, consider having it tested for arsenic and other contaminants.
  • Avoid swimming or wading in ponds, dams, or water bodies with walls or banks made from mine tailings or suspicious fill material.
