“…Several factors can affect the potential of septic tanks to contaminate groundwater resources, including the distance of the septic tanks to a water source, the topography or slope of the soil, and soil characteristics. Hydrological conditions including depth of the groundwater table (21), groundwater streamline (1), piezometric level of groundwater (24), and permeability of the unsaturated zone also contribute to groundwater contamination (25).…”

“…Escherichia coli is a fecal indicator bacterium that has a natural habitat in the large intestine of humans and warm-blooded animals as well as a secondary habitat in the environment (26). Therefore, Escherichia coli is also related to animal waste (25). The occurrence of contact with feces (27) followed by a lack of hygiene and sanitation practices (28) when taking, storing, and using the well water can be the cause of the entry of Escherichia coli into the well water.…”

Introduction: Padang City Sanitation Working Group reported that 34.32% of households in Padang City use unsafe latrines with septic tanks that still do not meet the standards which potentially causes the wastewater from the septic tanks to contaminate the water of the wells. This study was conducted to analyse the effects of the septic tank condition on the microbiological quality parameters of the well-water, namely total coliform and Escherichia coli in Koto Tengah District, Padang. Methods: This study uses a quantitative research method. The data were collected by questionnaires, observation, interviews, and laboratory tests. Water sampling was collected by using the purposive sampling method where the water is taken from 20 wells originating from 10 coastal and 10 non-coastal areas. Results and Discussion: Total coliform was found in all samples, while Escherichia coli was found in two samples from coastal and five from non-coastal regions. The septic tank condition had a strong correlation with the total coliform concentration (r= -0.531) and affected the total coliform concentration in the well-water by 30.8%. However, the Escherichia coli concentration was not related and not affected by the condition of the septic tank (p>0.05). There was no significant difference in the concentration of the microbiological parameters in the coastal and non-coastal areas. Conclusion: The microbiological quality of the well-water did not comply with the quality standards to be used as water sources for the community. The total coliform concentration in the well-water was shown to have a close relationship with the septic tank's condition.

“…Pathogens in manure pose a severe risk of spreading zoonotic diseases, for example, Ananna et al (2021) observed a significantly higher total viable count of fecal microorganisms in manure‐amended soils than non‐amended soils. Fecal microorganisms in manure can leach into shallow groundwater and pose a threat to human and animal health, for example, by polluting drinking water with fecal bacteria, which may result in diarrhea (Ananna et al, 2021; Sommer et al, 2013).…”

Animal manure has been used to manage soil fertility since the dawn of agriculture. It provides plant nutrients and improves soil fertility. In the last decades, animal husbandry has been significantly expanded globally. Its economics were optimized via the (international) trade of feed, resulting in a surplus of animal manure in areas with intensive livestock farming. Potentially toxic elements (PTEs), pathogenic microorganisms, antibiotic residues, biocides, and other micropollutants in manure threaten animal, human, and environmental health. Hence, manure application in crop fields is increasingly restricted, especially in hotspot regions with intensive livestock activities. Furthermore, ammonia volatilization and greenhouse gas (GHG) emissions during manure storage, field application, and decomposition contribute to air pollution and climate change. Conventional manure management scenarios such as composting and anaerobic digestion partially improve the system but cannot guarantee to eliminate sanitary and contamination risks and only marginally reducing its climate burden. Hence, this review discusses the potential of pyrolysis, the thermochemical conversion under oxygen‐limited conditions as an alternative treatment for animal manure providing energy and biochar. Manure pyrolysis reduces the bioavailability of PTEs, eliminates pathogenic microorganisms and organic micropollutants, and reduces GHG emissions. Pyrolysis also results in the loss of nitrogen, which can be minimized by pretreatment, that is, after removing soluble nitrogen fraction of manure, for example, by digestion and stripping of ammonia–nitrogen or liquid–solid separation. However, conclusions on the effect of manure pyrolysis on crop yield and fertilization efficiencies are hampered by a lack of nutrient mass balances based on livestock unit equivalent comparisons of manure and manure biochar applications. Hence, it is essential to design and conduct experiments in more practically relevant scenarios and depict the observations based on the amount of manure used to produce a certain amount of biochar.

“…The content of mineral elements in soil varies from place to place. In the mountainous region of the Yunnan-Guizhou Plateau, phosphorus and nitrogen are considered to be important factors that limit primary productivity and affect the distribution of plant communities (Ullah et al 2022, Ananna et al 2022, Weber et al 2021, Zhang et al 2021. In recent years, by studying the effect of soil phosphorus migration and transformation under the condition of dry-wet alternation, the migration and transformation process of soil phosphorus under the condition of dry-wet alternation has been explored, and the biochemical cycle process of soil phosphorus has been recognized in the process of dry-wet alternation (Arruda et al 2021, James et al 2021, Albadri et al 2021.…”

In the mountainous area of Yunnan-Guizhou Plateau, phosphorus and nitrogen are important factors that limit primary productivity and affect the distribution of plant communities. Alternation of wet and dry has a significant effect on the migration of various elements such as C, N, and P in soil. Taking the rhizosphere soil of the dominant plants in the phosphorus-rich mountainous area in the Dianchi Lake Basin as the research object. Six sets of different humidity treatment methods: blank constant humidity, blank dry and wet alternation, nitrogen constant humidity, nitrogen addition dry and wet alternation, carbon constant humidity, and carbon add dry and wet alternation were assessed. Responses of soluble total nitrogen and soluble total phosphorus to six treatments in plant root zone were investigated. The results showed that the contents of dissolved total nitrogen (DTN) and dissolved total phosphorus (DTP) in soil leachate and their changes of Erianthus rufipilus and Eupatorium adenophorum under different treatment conditions increased first and then decreased. In the carbon addition group, the DTN content of the soil leachate in the alternating dry and wet treatment was significantly higher than that in the constant humidity treatment, but there was no significant difference in the nitrogen addition group. The three factors of water treatment and sampling time have significant effects on the DTN content of soil leachate, and the interaction between the three also has a significant effect on it.
