• Action Level (AL): 1.3 ppm
• PHG: 0.3 ppm
• Amount Detected (90th %ile): 0.32 ppm
• Sites Above AL/Total Sites: 1 out of 35
• Violation: No
• Typical Source: Internal corrosion of plumbing, natural deposits

Lead (ppb)

• Year Sampled: 2022
• Action Level (AL): 15 ppb
• PHG: 0.2 ppb
• Amount Detected: Not Detected
• Sites Above AL/Total Sites: 1 out of 35
• Violation: No
• Typical Source: Plumbing corrosion, industrial discharge, natural deposits

Secondary Substances

Woodland also monitors secondary substances that, while not health-based, affect taste, odor, or appearance:

• Chloride (ppm): 5.8 ppm
• Odor Threshold Number (TON): 1.3
• Specific Conductance (µmho/cm): 190 µmho/cm
• Sulfate (ppm): 0.02 ppm
• Total Dissolved Solids (ppm): 125 ppm
• Turbidity (NTU): 0.34 NTU

These substances are within acceptable limits, indicating minimal impact on water quality beyond aesthetic considerations.

Woodland’s 2023 water quality report demonstrates our dedication to delivering safe and high-quality drinking water.
