Occurrence of hydrogen sulfide in the ground water of Kuwait

Evaluation of Urban Groundwater Contamination from Sewage Network in Kuwait City

“…In the present case, the water sample from the well HS-2 was most deficient in 2 H and 18 O (most negative values of δ 2 H and δ 18 O) compared to the SMOW composition. The well screens covered the depth range 11-45 m below the surface, and given the possible presence of an upward flow from the deeper aquifers in this area (Mukhopadhyay et al 2007), the isotope values in all probability, were characteristics of the deeper groundwater in Kuwait City area. The rest of the seven samples were collected from a depth range of 5-13 m covering the screened parts of the wells drilled for the current study and should represent near surface water.…”

Study of the effect of temperature, pH, and time on the desorption of H2S.

“…In the last 50 years, groundwater extraction has quadrupled, and it is estimated that it supplies 36% of drinking water, 42% of water for agriculture, and 24% of water for industrial use (FAO, 2016). Worldwide, a problem affecting groundwater quality is the presence of hydrogen sulphide, whether of natural or anthropogenic origin (Plummer et al, 1990; Mukhopadhyay et al, 2006;Bhuiyan et al, 2010). Hydrogen sulphide water contamination can occur in both urban and rural areas, with rural areas being the most affected by the lack of infrastructure to treat and condition water for use (Satapathy et al, 2017).…”

“…Hydrogen sulphide water contamination can occur in both urban and rural areas, with rural areas being the most affected by the lack of infrastructure to treat and condition water for use (Satapathy et al, 2017). Dissolved H2S, involving a variety of chemical, biological, and biochemical processes in natural water, is an important indicator of natural water quality, and its concentration level varies over time (Yimei et al, 2023), occurs in different concentrations (0.1 to 244 mg/l) where < 20, 20 to 50, 50 to 150 and > 150 mg/L in groundwater can be considered low, medium-low, medium-high and high, respectively (Mukhopadhyay et al, 2006;O'Sullivan et al, 2005). In nature, water could be contaminated by geochemical processes by geothermal and sulphide minerals dissolves (Bondu et al, 2017;Akai et al, 2004).…”

H2S near-IR QEPAS detection in complex gas matrices

“…The Occupational Safety and Health Administration (OSHA, US Department of Labor) established the concentration limit for H2S breathing at 20 part per million (ppm), for an eight-hour period, with a maximum inhalation of 50 ppm for ten minutes 1,2 . H2S occurs naturally in the environment, particularly in ground water, areas with volcanic activity or oil and gas deposits [3][4][5][6] . In industry, H2S is used as a chemical intermediate in the production of several products, including sulfuric acid, fertilizers, and rubber.…”
