Special Issue Information

Dear Colleagues,

Groundwater contamination by nitrate is a widespread problem all over the world. Aquifer pollution causes public health problems and environmental degradation of ecosystems. All these negative effects can be minimized with an integrated groundwater management and a good governance to mitigate the risks of nitrate contamination. In order to ensure sustainable use and protection of groundwater aquifers, water resources specialists and decision makers need information on the scope, distribution, and severity of aquifer nitrate contamination. In other words, the identification of nitrate sources, early diagnosis of possible changes, and knowledge for selecting effective remediation strategies are essential.

In compliance with these requirements, the contributors of this Special Issue are invited to submit papers focusing on the presentation of models and applications following the concept of “pressure–pathway–receptor”, whereby the information on point and nonpoint sources of water pollution (fertilizer, livestock manure, septic tanks, municipal and industrial effluents) is combined with aquifer vulnerability parameters (depth of water table, recharge, aquifer material, soil type, topography, and hydraulic conductivity, among others) and eventually with biogeochemical models, to explain nutrient yields arriving at the receptor (groundwater).

We believe that this Special Issue will help to bring to the attention of land use planners, water resources managers, and the general public that conservation of groundwater resources begins with a reliable land use and implementation of conservation measures, and that deviation from this practice inevitably leads groundwater resources to danger and ultimately to collapse as a service provider.

Detailed full-scale groundwater monitoring was carried out over a period of nine years, sampling at selected points along the groundwater flow direction in its final stretch. This established the hydrogeochemical evolution along the flow of a natural system formed by a calcareous aquifer which discharges and then passes through a quaternary aquifer of lake origin which is rich in organic matter. This evolution is highly conditioned by the oxidation of pyrites that are abundant in both aquifers. In the first aquifer, one kilometre before the discharge location, oxidizing groundwater crosses a pyrite mineralization zone whose oxidation produces an important increase in sulphates and water denitrification over a short period of time. In the quaternary aquifer with peat sediments and pyrites, water experiences, over a small 500 m passage and residence time of between three and nine years, a complete reduction by way of pyrite oxidation, and a consequent increase in sulphates and the generation of hydrogen sulphuric acid. This is an example of an exceptional natural hydrogeological environment which provides guidance on hydrogeochemical processes such as denitrification. Full article

Non-point source pollution is a major factor in excessive nutrient pollution that can result in the eutrophication. Land use/land cover (LULC) change, as a result of urbanization and agricultural intensification (e.g., increase in the consumption of fertilizers), can intensify this pollution. An informed LULC planning needs to consider the negative impacts of such anthropogenic activities to minimize the impact on water resources. The objective of this study was to inform future land use planning by considering nutrient reduction goals. We modeled the LULC dynamics and determined the capacity for future agricultural development by considering its impacts on nitrate runoff at a watershed scale in the Tajan River Watershed in northeastern Iran. We used the Soil and Water Assessment Tool (SWAT) to simulate the in-stream nitrate concentration on a monthly timescale in this watershed. Historical LULCs (years 1984, 2001 and 2010) were derived via remote sensing and were applied within the Land Change Modeler to project future LULC in 2040 under a business-as-usual scenario. To reduce nitrate pollution in the watershed and ecological protection, a conservation scenario was developed using a multi-criteria evaluation method. The results indicated that the implementation of the conservation scenario can substantially reduce the nitrate runoff (up to 72%) compared to the business-as-usual scenario. These results can potentially inform regional policy makers in strategic LULC planning and minimizing the impact of nitrate pollution on watersheds. The proposed approach can be used in other watersheds for informed land use planning by considering nutrient reduction goals. Full article
