The Peatland pH Project
CWSF · 2026 Environment & Climate Change
Overview
Our project investigated how soil pH and density change over time using a peat core sample from a peatland in Sudbury (Lake Laurentian Conservation Area) and a peatland outside of Nairn Centre. The results showed a decrease in pH (higher acidity) at certain depths, likely caused by historical mining pollution, while deeper layers had higher pH levels representing pre-mining conditions. Density also varied with depth, providing additional evidence of changes in soil composition and environmental conditions over time.
