Special Issue Information

Dear Colleagues,

Anthropogenic activities influence the groundwater chemical status. Organic microcontaminants are a real threat to groundwater because even in low concentrations can negatively affect human health. Emerging contaminants in the water environment have been of growing concern in recent years. The most popular substances are persistent organic pollutants (POPs), polycyclic aromatic hydrocarbons (PAHs), pesticides, pharmaceuticals and cosmetics, residues of which occur in both surface water and groundwater. Among the main sources of these substances are insufficient sewage treatment and landfill leachates. In spite of low concentrations of PPCPs in water samples, these compounds constitute a threat to living organisms due to their potential for bioaccumulation. Some of the microcontaminants are also included in the group of endocrine-disrupting chemicals that affect the function of the hormonal system. In this regard, pharmaceuticals and personal care products are hazardous for human health since their residues are occasionally detected in drinking water. Due to the fact that compounds of this type may affect groundwater to a varying degree, it is advisable to assess the risk of groundwater using various available methods, both field and modeling.

Environmental degradation caused by the migration of pollutants from landfills is one of the biggest problems for urban areas. Systematic monitoring of groundwater in the vicinity of waste dumps allows for an assessment of the degree of risk to the soil and water environment. In this paper, spatiotemporal variation of groundwater pollution near a municipal landfill in Sosnowiec (southern Poland) was investigated. For this purpose, the monitoring results of five physicochemical indicators from 2014–2019 were used. This study presents an example of the application of the Landfill Water Pollution Index (LWPI) and the Cd Contamination Index. The obtained results indicated that the tested waters were negatively influenced by municipal landfills, especially in the southern part (piezometers P8 and P10). The values of the Contamination Index even reached a value equal of about 1400, while the values of the LWPI index reached 305. Significantly lower values of both indicators were obtained using the results of monitoring studies for other piezometers located upstream from the landfill but belonging to the observation network of a neighboring facility. The indices used permit a determination of the level of groundwater contamination from the described landfill and can be used in similar research areas. Full article

The groundwater risk assessment in the vicinity of landfill sites requires, among others, representative monitoring and testing for pollutants leaching from the waste. Lysimeter studies can serve as an example of dynamic leaching tests. However, due to the bacteriological composition of the municipal waste, they are rarely carried out. These tests allow for the proper design of the landfill protection system against migration of pollutants into the ground, assessment of bacteriological, biochemical and chemical risk for the groundwater, determination of the water balance of leachate as well as examination of the course of processes taking place in the waste landfill with a diversified access to oxygen. This paper addresses the issue of performing lysimeter studies on a sample of municipal waste in various scientific centers. It analyzes the size of lysimeters, their construction, the method of water supply, the duration of the experiment, the scope of research, and the purpose of lysimeter studies. Full article

Title: USE OF PLANT PROTECTION PRODUCTS IN LOMBARDY - ITALY AND THE RISK FOR THE INGESTION OF CONTAMINATED WATER

Abstract: Pesticides used to protect agricultural crops may contaminate groundwater. This work aimed to identify the number and amount of pesticides used in Lombardy, Italy in 2016, to assess the risk for health associated with the intake of drinkable water in the adult population. Data of agricultural areas, pesticides sold and concentrations of pesticides in the groundwater were obtained from databases of regional and national bodies. Lombardy agricultural area is 980,112 h, mainly cultivated with cereals (74%). In 2016 approximately 4,200 pesticides (135,000 q), containing 412 active substances (31,000 q) were sold. Out of the 10 best-sold active substances, 6 were herbicides. There were 8,173 groundwater contamination measurements in 397 municipalities, monitoring 32 active substances of which 5 belonging to the best-sold substances. The environmental quality standards were exceeded in 2% of these measurements, with a risk for health associated with the intake of contaminated water in the adult population typically ranging between 10-3 and 10-4. A large number and amount of active substances were sold in Lombardy, but only a minor part was included in the official controls of groundwater. For measured active substances, the contamination of groundwater indicated an irrelevant risk for the adult’s population.
