Abstract High Temperature Aquifer Thermal Energy Storage (HT-ATES) has developed from
a demonstration stage to a mature technology over the past decades. The specific storage …

Abstract The PHREEQ-N-AMDTreat aqueous geochemical modeling tools described herein
simulate changes in pH and solute concentrations resulting from passive and active …

Passive water treatments based on biological attenuation can be effective for arsenic-rich
acid mine drainage (AMD). However, the key factors driving the biological processes …

Organic ligands are widely distributed and can affect microbially driven Fe biogeochemical
cycles, but effects on microbial iron oxidation have not been well quantified. Our work used a …

The sustainability of ground-source geothermal systems can be severely impacted by
microbially mediated clogging processes. Biofouling of water wells by hydrous ferric oxide is …

The rates of microbial and abiotic iron oxidation were determined in a variety of cold (T= 9–
12° C), circumneutral (pH= 5.5–9.0) environments in the Swiss Alps. These habitats include …

Heavy metal‐contaminated, pH 6 mine water discharge created new streams and iron‐rich
terraces at a creek bank in a former uranium‐mining area near Ronneburg, Germany. The …

Clogging by incrustations of nine groundwater heat pump (GWHP) systems in Melhus,
Norway have been investigated by field and laboratory methods for water quality and …

Well clogging due to iron (hydr) oxide precipitation can negatively influence the
performance, or even cause failure, of aquifer thermal energy storage (ATES) wells in …

Abstract The ubiquitous β-Proteobacterium Gallionella ferruginea is known as stalk-forming,
microaerophilic iron (II) oxidizer, which rapidly produces iron oxyhydroxide precipitates …
