Possible reasons for Fresno’s higher lead levels:
- Older plumbing infrastructure in some areas
- Historical use of lead-containing materials
Bacteria
Bacterial presence in water:
- Dorsten: <1 CFU/100mL
- Fresno: 3 CFU/100mL
While both cities maintain low bacterial levels, Fresno’s slightly higher count may be due to:
- Differences in water treatment processes
- Potential contamination sources in the water supply system
