Executive Summary
The pH of the Duck Pond is slightly basic but is within acceptable ranges. Duck Pond is mostly immune to drastic swings in pH because it is mostly groundwater, but can be affected by drainage as observed in 2023.
What is pH?
pH is a scale from 0 to 14 that measures how acidic or basic a substance is.
Why Does pH Matter?
it affects aquatic organisms' metabolism, reflects contaminant levels, and helps tell the health of aquatic life
What Can Help pH Stay Normal?
Buffering by dissolved minerals keeps pH stable
Short time window limits pH change
Sampling variability could mask small differences.
pH Range Names.
Acidity: less than 7 on the pH scale is acidic. Lemons are acidic.
Neutrality: exactly 7 is neutral. Pure water is neutral.
Alkalinity: more than 7 is basic or alkaline. Baking soda is basic.
September 9/26-9/30 2025
p-value: 0.4
No significant difference
Both are in normal pH range
2025 vs 2024
p-value: 0.83
No significantly different P- Value
Both are in normal range of PH levels
2025 vs 2023
P- value: 0.02
Both are in normal pH level range
Significantly higher in 2023
Could be due to timing of 2023 sampling after storm water input from nearby roads that drain into the Duck Pond carrying a basic pollutant from the roadway
