The mean radon-in-water levels for shallow aquifers were systematically higher (55 ± 10 Bq/L) compared to deep (14 ± 3 Bq/L) or mixed aquifers (20 ± 6 Bq/L).
与深层含水层(14±3 Bq/L)或混合含水层(20±6 Bq/L)相比,浅层含水层的平均水中氡水平(55±10 Bq/L)系统性地更高。

Rural communities in sub-Saharan Africa commonly rely on shallow hand-dug wells and springs; consequently, shallow aquifers are an extremely important water source.
撒哈拉以南非洲的农村社区通常依赖浅水井和泉水;因此,浅层含水层是极其重要的水源。

This study indicates that upwelling of deep CO2-rich fluids with long-term water-rock interactions can be harmful to shallow potable groundwaters by supplying high levels of trace elements into shallow aquifers.
这项研究表明,具有长期水-岩相互作用的深层富含二氧化碳的流体的上涌通过向浅层含水层提供高水平的微量元素可能对浅层可饮用地下水有害。
