Hydraulic fracturing of the Marcellus Shale produces wastewaters that are hypersaline and highly enriched in isotopes of radium. Radium is understood to derive from the Marcellus Shale itself, but its source phases and their contributions to wastewat

The hydrogeological and biogeochemical importance of submarine groundwater inputs has recently been highlighted. Numerous studies around the world have shown that these contributions can challenge fluvial inputs. However, very few studies have been c

Numerous investigators have used the advection–diffusion equation and the distributions of the four isotopes of radium to model coastal mixing rates. However, there is a dichotomy in approach. Some models use the short-lived 224 Ra ( T 1/2 =3.7 day
