Special Issue Information

Dear Colleagues,

Access to potable water is under massive pressure from rapid urbanization, groundwater has become the primary source of water for approximately 1.5 billion people worldwide. There is a growing realization that the provision of high-quality groundwater is a crucial element in solving the shortage of potable water. However, in recent decades, despite important improvements achieving in water purification, access to the investigation and remediation for groundwater is not universal. Although groundwater quality is regulated and monitored in many countries, increasing knowledge leads to the need for reviewing the assessment standards and methods for groundwater quality, both for regulated and newly identified contaminants. The resource of contaminant also needs to be analyzed to make an approach to control.

This Special Issue of IJERPH focuses on the current state of knowledge on the investigations of groundwater, such as the assessment of groundwater chemistry and quality, the source of contaminants, the health risks of contaminants at groundwater, the remediation technology of contaminated groundwater, the relationship between human activity and groundwater quality, the legal construction of groundwater treatment. and so on. Papers addressing these topics are invited for this Special Issue, especially those combining a high academic standard coupled with a practical focus on remediating groundwater.

Here, are some examples of topics that could be addressed in this Special Issue:

  1. The assessment of groundwater chemistry and quality.
  2. The source of contaminants at groundwater.

    Microorganisms and infectious diseases: virus, bacteria, parasites, etc.

    Natural contaminants: arsenic, barium, manganese, fluoride, radiation, etc.

    Anthropogenic chemicals: nitrate, sulfate, pesticides, pharmaceutical, PPCPs, hormone, antimicrobial resistance, etc.

  3. The health risks of contaminants at groundwater.
  4. The remediation technology of groundwater.
  5. The legal construction of groundwater treatment.
  6. The relationship between human activity and groundwater quality.

Infant mortality in Kazakhstan is six times higher compared with the EU. There are several reasons for this, but a partial reason might be that less than 30% of Kazakhstan’s population has access to safe water and sanitation and more than 57% uses polluted groundwater from wells that do not comply with international standards. For example, nitrate pollution in surface and groundwater continues to increase due to intensified agriculture and the discharge of untreated wastewater, causing concerns regarding environmental and human health. For this reason, drinking water samples were collected from the water supply distribution network in eight districts of Almaty, Kazakhstan, and water quality constituents, including nitrate, were analyzed. In several districts, the nitrate concentration was above the WHO and Kazakhstan’s maximum permissible limits for drinking water. The spatial distribution of high nitrate concentration in drinking water was shown to be strongly correlated with areas that are supplied with groundwater, whereas areas with lower nitrate levels are supplied with surface water sources. Based on source identification, it was shown that groundwater is likely polluted by mainly domestic wastewater. The health risk for infants, children, teenagers, and adults was assessed based on chronic daily intake, and the hazard quotient (HQ) of nitrate intake from drinking water was determined. The non-carcinogenic risks increased in the following manner: adult < teenager < child < infant. For infants and children, the HQ was greater than the acceptable level and higher than that of other age groups, thus pointing to infants and children as the most vulnerable age group due to drinking water intake in the study area. Different water management options are suggested to improve the health situation of the population now drinking nitrate-polluted groundwater. Full article
