Smithfield Water Quality
What's in Smithfield's water
Atrazine
Violation on record
1 EPA violation on record (most recent 2025). Atrazine is one of the most widely used weed killers and reaches water through agricultural runoff. It is an endocrine disruptor associated with reproductive and developmental effects, and concentrations tend to spike seasonally after application. It is most common in farming regions.
Radium (combined -226 & -228)
Violation on record
1 EPA violation on record (most recent 2025). Radium is a naturally radioactive element that leaches from rock into groundwater. Long-term exposure increases the risk of bone cancer and other cancers because it concentrates in bone. The federal limit covers the combined activity of radium-226 and radium-228.
PFOA
Violation on record
1 EPA violation on record (most recent 2025). PFOA is a long-lived "forever chemical" once used to make nonstick and stain-resistant products. It builds up in the body over time and is associated with certain cancers, immune effects, and developmental harm. EPA finalized a strict drinking-water limit for it in 2024.
Gross Beta / Photon Emitters
Violation on record
1 EPA violation on record (most recent 2025). Beta and photon emitters are radioactive contaminants that can come from natural deposits or from nuclear activity. Long-term exposure increases cancer risk. The federal limit is expressed as an annual dose rather than a simple concentration.
Nitrate
Violation on record
1 EPA violation on record (most recent 2020). Nitrate enters water mainly from fertilizer runoff, septic systems, and animal waste. High levels can interfere with the blood's ability to carry oxygen, a special danger for infants. Long-term low-level exposure has also been linked to elevated cancer risk in some studies.
Water hardness
very hard
Smithfield's water is very hard. Hardness isn't a health risk, but it drives scale on fixtures and water heaters, shortens appliance life, and leaves skin and hair dry.
