Acid Generating Potential
nounPronunciation: /ˈæsɪd ˈdʒɛnəreɪtɪŋ pəˈtɛnʃəl/
The capacity of exposed sulfide minerals (particularly pyrite) in mine waste to oxidize and produce sulfuric acid when exposed to air and water, lowering pH and mobilizing heavy metals. Assessment of acid-generating potential is critical for predicting long-term water quality impacts and designing appropriate containment strategies.
Plain English
The ability of certain minerals in mine waste to create acid over time, which pollutes water and harms ecosystems.
Etymology & History
Usage
"Geochemical testing revealed high acid-generating potential in the tailings, necessitating permanent capping and groundwater monitoring."
Style guide notes: Use hyphenated form 'acid-generating' as adjective; sometimes abbreviated as 'AGP' in technical documents.
