Compound specific isotope analysis (CSIA) is a powerful technique to demonstrate in situ degradation of traditional groundwater contaminants when concentrations are typically the mg/L range. Currently, an efficient preconcentration method lacking expand CSIA low aqueous concentration environmental samples. Specially for H- and N-CSIA heteroatom-bearing non-traditional compounds, analytical detection limits significantly higher than that C-CSIA. This work demonstrated compatibility polar organic chemical integrative sampler (POCIS) with C-, H-, using four nitro- amino-substituted chlorobenzenes common industrial feedstock numerous applications commonly detected environment at µg/L Using lab experiments, we showed isotopic equilibrium POCIS was achieved after 30 days either negligible (<0.5‰) or reproducible shift C (<1‰) N (<2‰).

The canonical water cycle assumes that all entering the subsurface to form groundwater eventually reenters surface by discharge lakes, streams, and oceans. Recent discoveries in dating have challenged understanding. Here we introduce a new conceptual framework includes large volume of is estimated account for 30–46% planet's but not yet incorporated traditional cycle. This immense hidden hydrogeosphere has been overlooked date largely because it stored deeper crust, on long timescales ranging from tens thousands more than one billion years. demonstrate why understanding this deep, old critical society's energy, resource, climate challenges as deep an important target exploration resources helium, hydrogen, other elements green energy transition; under investigation geologic repositories nuclear waste carbon sequestration; biome biosphere significant proportion Earth's biomass. ▪We provide hydrogeosphere, previously unrecognized cycles.▪Geochemico-statistical modeling age distributions allows deconvolution timing, rates, magnitudes key crustal processes.▪Understanding are addressing challenges.
