“…Aquatic groundwater-dependent ecosystems are at risk under climate change scenarios (Taylor et al 2013), thus losing biodiversity and related ecosystems services (Mammola et al 2019a). Groundwater biodiversity has long been underestimated due to difficult sampling (Ficetola et al 2019), and its conservation has never been a priority, especially with respect to the many regulations issued for protecting ground water as primary source of water supply for drinking purposes (Fouché et al 2019). This perception has gradually changed and a manifesto to intervene on the conservation of the most precious water resource and the intimately cross-linked biodiversity was signed by many scientists (Mammola et al 2019b).…”

Biodiversity hotspots are routinely identified by grid‐based analyses, despite grids encompassing different habitats, thus hindering the potential to assess which habitat type accounts for the conservation priority assigned to a grid. In this study, we aimed at identifying the main hotspots for the conservation of the European stygobitic Crustacea Copepoda Harpacticoida at the groundwater habitat scale. A multi‐metric approach was used, based on six biodiversity indicators: species richness, endemicity, evolutionary origin, phylogenetic rarity, taxonomic distinctness, habitat specificity. The Hot Spot Analysis, based on the statistics Getis‐Ord Gi*, was used to compare the local to the global average values of each indicator to identify hotspots of conservation. The operational units used to perform the analyses were the groundwater habitat types, in order to gather all the possible patterns of spatial occupancy in terms of habitat variability. Eight biodiversity hotspots of stygobitic Crustacea Harpacticoida were highlighted: 1) the Pyrenees (Spain and France), 2) the Jura Massif (France), 3) the Alpine arc (France, Switzerland and Italy) embracing southward the River Po alluvial plain and the Slovenian External Dinarides, 4) the Central Apennines (Italy), 5) the Carpathian and Balkan mountains in Romania and at the boundary between western Bulgaria and north‐west Macedonia, 6) the Dinaric Alps (from Croatia to Albania), 7) the Sardinia Island, 8) an area in central‐northern Europe embracing Denmark, the Netherlands and Germany. The hotspots showed a clear spatial distribution in southern Europe where they were distributed predominantly south to the 45th parallel, in line to what reiteratively observed in previous studies. Many hotspots embraced more than one habitat type. The adoption of discrete groundwater habitat types as working spatial units rather than grids provided a higher resolution of where the stygobitic harpacticoid species effectively live, with the possibility of intervening more precisely to preserve them and their habitats.

“…Due to the high cost involved in sewered sanitation, ANC has emerged as the preferred mode in cities experiencing rapid urbanization, and this practice has put severe stress on groundwater and river quality (Diaw et al, 2020; Fouché et al, 2019; Pujari et al, 2012). OSS systems (e.g., septic tanks) are widely used in low‐ and middle‐income countries (Odagiri et al, 2021; Otaki et al, 2021; Thaher et al, 2022).…”

In application of the European Water Framework Directive, the water development and management plan, Schéma d'aménagement et de gestion des eaux (Sage) for the Lys (Lily) watershed area sets out general objectives for the use, development, and quantitative and qualitative protection of water resources and aquatic environments. The Lys Sage issues include the pollution of aquatic media and a provision for reducing the impact of discharges from on‐site sanitation devices. The prioritization of public authority action on on‐site sanitation requires the definition and identification of zones with environmental issues. The objective is to identify priority areas for the rehabilitation of noncompliant on‐site sanitation devices in case of a proven risk of pollution. These zones have been identified and mapped following the development and application of a methodology based on current regulations, feedback, and an innovative approach. It is based on the risk assessment of on‐site sanitation. To do this, a hazard (source hydraulic flow) was crossed with the vulnerability of the environment (target flow impact on stream quality). In addition to vulnerability assessed by the chemical quality of watercourses, the concept of zones of ecological interest was introduced.

“…Self-purification is also hindered by the presence of TMEs in water. TMEs cannot be degraded or metabolised and are an example of ultimate persistence [1] [2]. Amongst TMEs, arsenic, copper, cadmium, lead, mercury, nickel and zinc are those that have most severely affected the environment.…”

In this work, an inexpensive and environmentally friendly natural adsorbent obtained from shelled (GD) and unshelled (GND) Moringa oleifera seeds was used for copper adsorption from aqueous solutions. A series of experiments were performed to assess the parameters influencing the adsorption phenomenon such as pH, adsorbent mass, adsorption equilibrium time and temperature. The kinetic results of adsorption described a pseudo-second order model. The adsorption isotherms are satisfactorily described by the Langmuir mathematical model. The thermodynamic data revealed a spontaneous and endothermic adsorption phenomenon. The level of copper in surface water before and after addition of moringa powders was carried out to verify the effectiveness of the adsorbent. A maximum adsorption rate of 51.28% and 61.96% was obtained with GD and GND powders respectively. Moringa oleifera seed powders are an effective alternative for the removal of copper from surface water.
