Results for UPLAND, CITY OF
1 water provider directly on file, serving roughly 78,376 people in San Bernardino County, California.
Quick answer: UPLAND, CITY OF has no violation currently counted toward its compliance status. EPA's record shows a Nitrate violation dating to 08/01/1987 (39 years ago) — because it's more than five years past its deadline, EPA's policy no longer treats it as part of this system's current standing, though it remains on the public record.

Commonly from agricultural fertilizer runoff or septic systems. Above the legal limit, it's an immediate concern especially for infants.
Contaminants found
Metals
Naturally occurring or corrosion-related elements, e.g. lead, arsenic, copper
Lead Summary
Detected: 0 mg/L (ppm)
12/31/2023
Combined Uranium
Detected: 1.9 PCI/L
7/7/2025
A naturally occurring radioactive metal. Long-term exposure above the legal limit is associated with kidney effects and increased cancer risk.
Chromium
Detected: 2.3 UG/L (ppb)
4/7/2025
Occurs in two forms — trivalent (an essential nutrient in trace amounts) and hexavalent (linked to increased cancer risk).
Barium
Detected: 44 UG/L (ppb)
4/7/2025
Arsenic
Detected: 1.6 UG/L (ppb)
2/25/2025
Occurs naturally in some groundwater. Long-term exposure above the legal limit (10 ppb) has been linked to increased cancer risk and cardiovascular disease.
Aluminum
Detected: 260 UG/L (ppb)
8/12/2025
Iron
Detected: 45 UG/L (ppb)
3/11/2025
Mostly an aesthetic issue (metallic taste, staining) rather than a health concern at typical levels.
Manganese
Detected: 10 UG/L (ppb)
2/18/2025
