Due to increasing global demand for fresh water, it is increasingly necessary to understand how aquifer pumping affects groundwater chemistry. However, comprehensive predictive relationships between pumping and groundwater quality have yet to be developed, as the available data, which are often collected over inconsistent time intervals, are poorly suited for long-term historical correlation studies. For example, we needed an adequate statistical method to better understand relationships between pumping rate and water quality in the City of Norman (OK, USA).

- Dissolved copper (Cu) from acid mine drainage (AMD) is toxic to aquatic life, and its interaction with organic ligands like fulvic acids (FAs) affects its bioavailability.* -
- The study analyzed FAs from pristine, AMD, and mixed waters in Colorado, finding that Cu was more toxic when associated with geochemically altered FAs, indicating how these interactions influence toxicity levels in aquatic systems.* -
- Using spectral properties of FAs improved predictions of Cu toxicity in laboratory tests, but some measurement discrepancies remained, suggesting that the complexity of FAs in AMD may hold unknown factors impacting metal binding.*
