“…After analysis of docu-mented studies, scientific monitoring is an essential starting point for controlling seawater intrusion (Kibria, 2016). To minimize the effects of seawater intrusion, the following methods are useful (Hoover et al, 2011;Stein et al, 2016): century, when coal and metal mines were of particular interest (Ji et al, 2013). Due to the depletion of ore reserves and declining economic conditions in the 1970s, most mines were closed, including coal, silver, gold, and other metal mines ).…”

This study discusses various issues and possible solutions related to groundwater resource and water quality in Korea. Groundwater is an important water resource in Korea, accounting for approximately 13% of the total annual domestic, agricultural, and industrial water supplies. From 1996 to 2014, groundwater usage increased by 45% while the number of wells increased by 102%. However, repeated occurrences of Foot and Mouth Disease and Avian Influenza led to nationwide mass burials of livestock and major effect of groundwater contamination. In coastal areas, anthropogenic activities were considered as the cause of seawater intrusion near the shore and far (7,000 m) from the coast. Thousands of abandoned metal mines and unregulated mining wastes have serious environmental effects in Korea; crop cultivation in metal contaminated soil and irrigation using metal contaminated water negatively affect human health. Moreover, urbanization is a major source of groundwater contamination due to intensified industrial activities. The Korean government has made major efforts to deal with the groundwater issues, including implementation of the Groundwater Act in 1996. Since then, various national monitoring systems have been established to examine changes in groundwater quality and quantity. Additional recent important groundwater quality issues need attention and must be resolved to ensure groundwater safety in Korea.

“…Saline groundwater (SGW) refers to groundwater collected from the coastal aquifers. SGW is rich in minerals, such as Ca and Mg, and is lower in salinity and pH compared with seawater [10,11]. According to a 2014 study conducted by the Korea Institute of Ocean Science and Technology, SGW from Uljin, a town on the eastern coast of South Korea, showed protective effects against 2,4-dinitrochlorobenzene-(DNCB-) induced AD-like skin lesions in the murine model [12].…”

Background. Saline groundwater, collected from the east coast of Korea, has been shown to have protective effects against 2,4-dinitrochlorobenzene- (DNCB-) induced atopic dermatitis-like skin lesions in the murine model. Objectives. To determine the effects of saline groundwater solution baths as a treatment of mild-to-moderate atopic dermatitis. Methods. Twenty-four subjects with mild-to-moderate atopic dermatitis were instructed to take a bath in saline groundwater solution for 20 minutes per day for two weeks. Evaluations were performed at baseline and week 2, including SCORing Atopic Dermatitis (SCORAD) index, corneometry, transepidermal water loss, visual analogue scale for pruritus, and collection of adverse events. Results. Subjects showed significant improvement with respect to the SCORAD index, skin hydration, transepidermal water loss, and pruritus at week 2 when compared with the baseline. Conclusion. Baths in saline groundwater solution may be an alternative therapeutic strategy for treating atopic dermatitis.

“…where n is the porosity, B (L) is the lens thickness, and d (L) is the depth. The growing interest in the use of brackish and saline groundwater as feed water for desalination plants [10], however, necessitates a reevaluation of the usefulness of isotopic tracers for studying saltwater dynamics. Tritium has been detected in brackish and saltwater in coastal aquifers in Tahiti [11], Israel [12], Morocco [13], the Netherlands [14], China [15], and Australia [16].…”

Behaviour of Tritium and Tritiogenic Helium in Freshwater Lens Groundwater Systems: Insights from Langeoog Island, Germany

et al. 2019

Tritium (3H) and its daughter product 3He have been widely used as tracers in hydrological studies, but quantitative analyses of their behaviour in freshwater lenses and the transition zone in coastal aquifers are presently lacking. In this paper, the fate of 3H and 3He in the freshwater lens and the transition zone as well as the saltwater wedge is studied using numerical variable-density flow and transport models of different degrees of complexity. The models are based on the conditions on the German island of Langeoog, which is uniquely suited for this purpose because of the high 3H concentration of the North Sea. It is found that most bomb-related tritiogenic 3He still resides in the freshwater lens, making it a useful tracer for young (<60 years) groundwater. Differences in dispersive transport between 3H and 3He can cause an apparent age bias on the order of 10 years. Under favourable conditions, 3H from seawater can penetrate deep into the offshore part of the aquifer and has potential to be used as a tracer to study saltwater circulation patterns. Our modelling suggests that the field-observed 3H in the transition zone does not originate from seawater but from freshwater affected by the bomb peak. Yet in models with a low (αL=0.5 m) dispersivity, no 3H was sequestered into the transition zone and the transition zone width was underestimated. Better results were obtained with αL=5 m, a value that is higher than in comparable modelling studies, which suggests that further work is needed to better understand the controls (tides, lithological heterogeneity, or transience of recharge and pumping) on transition zone mixing processes.
