Vertical water flows can occur within the artificial or natural filter pack annulus that surround the screened interval, bypassing packer assemblies installed inside the wellbore. Attempts to isolate discrete vertical zones during groundwater sampling are unsuccessful when annular vertical flow occurs which lead to remedy decisions based on biased or incorrect interpretations. Blocking vertical annular water flow and contaminant transport will help obtain more accurate concentrations of contaminants from sampling in targeted depth intervals. The application of silica gels formed from the injected colloidal silica (CS) suspensions is a novel approach to minimize or prevent vertical movement of groundwater in the surrounding filter pack annulus. In this study, we tested the feasibility of injecting CS suspensions to target locations and developed a modified CS formulation that is injectable and prevents gravity sinking. We studied the spatial distribution and penetration of silica gel at laboratory scale in model well annulus with surrounding formations. We evaluated the performance of the silica gel in blocking vertical water flow in the annulus and in minimizing chemical transport through the gel zone. CS suspension formulations have been defined that are ready for injection, persist in target locations, and form gel within desired time frames. Injection of CS suspensions achieved uniform distribution in a well annulus filter pack, fully occupied the annulus pore space, and penetrated the formation surrounding the filter packer with a sufficient distance to create a hydraulic annular seal when the injection was applied at a sufficient rate. Silica gel that formed in the annulus blocked vertical water flow and stopped the chemical transport through the gel zone. This research reveals that using CS suspension injection and sequential gelation (CS-GEL) is a promising technology for blocking vertical water flow and chemical transport through the filter pack in targeted zones within the annulus of long-screened well systems.</div></div>","PeriodicalId":15530,"journal":{"name":"Journal of contaminant hydrology","volume":"269 ","pages":"Article 104510"},"PeriodicalIF":3.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143369821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We observed a significant increase in the specific surface area (SBET) of TWPs after aging, from an initial 2.81 ± 0.29 to 6.63 ± 0.16 m²/g for ozone-aged TWPs.

Conversely, the adsorption of SDZ and TC was reduced post-aging, suggesting a complex interaction between antibiotic physicochemical properties and TWPs' surface characteristics. The pseudo-second-order model, indicating chemisorption interactions, effectively described the adsorption kinetics, with the Freundlich isotherm model capturing the adsorption behavior more accurately than the Langmuir model.

Hence, accurate quantification of denitrification rates is consequently important for the better understanding and assessment of nitrate contamination of groundwater systems. There are, however, few studies that have investigated quantification of shallow groundwater denitrification rates using different analytical approaches or assuming different kinetic reaction models. In this study, we assessed different analytical approaches (reactant versus product) and kinetic reaction (zero-order and first-order) models analysing observations from a single-well, push-pull tests to quantify denitrification rates in shallow groundwater at two sites in the Manawatū River catchment, Lower North Island of New Zealand. Shallow groundwater denitrification rates analysed using the measurements of denitrification reactant (nitrate reduction) and zero-order kinetic models were quantified at 0.42–1.07 mg N L⁻¹ h⁻¹ and 0.05–0.12 mg N L⁻¹ h⁻¹ at the Palmerston North (PNR) and Woodville (WDV) sites, respectively. However, using first-order kinetic models, the denitrification rates were quantified at 0.03–0.09 h⁻¹ and 0.002–0.012 h⁻¹ at the PNR and WDV sites, respectively. These denitrification rates based on the measurements of denitrification reactant (nitrate reduction) were quantified significantly higher (6 to 60 times) than the rates estimated using the measurements of denitrification product (nitrous oxide production). However, the denitrification rate quantified based on the nitrate reduction may provide representative value of denitrification characteristics of shallow groundwater systems. This is more so when lacking practical methods to quantify all nitrogen species (i.e., total N, organic N, nitrite, nitrate, ammoniacal N, nitrous oxide, nitric oxide, and nitrogen gas) in a push-pull test. While estimates of denitrification rates also differed depending on the kinetic model used, both a zero-order and a first-order model appear to be valid to analyse and estimate denitrification rate from push-pull tests. However, a discrepancy in estimates of denitrification rates using either reactant or product and using zero- or first-order kinetics models may have implications in assessment of nitrate transport and transformation in groundwater systems. This necessitates further research and analysis for appropriate measurements and representation of spatial and temporal variability in denitrification characteristics of the shallow groundwater system.</div></div>","PeriodicalId":15530,"journal":{"name":"Journal of contaminant hydrology","volume":"269 ","pages":"Article 104500"},"PeriodicalIF":3.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143023367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the impact of the transformation process, particularly involving the metastable phase brushite (DCPD), on the fate of antibiotics remains unclear. In this study, we synthesized DCPD and hydroxylapatite (HAP) and examined their transformation process to assess their removal capacity and investigate the migration and fate of oxytetracycline (OTC). The findings reveal that HAP exhibits a maximum immobilization capacity for OTC of 20.10 mg/g, surpassing that of DCPD by 2.56 times (7.86 mg/g). This disparity in immobilization capacity between DCPD and HAP leads to a redistribution of OTC between the solid and liquid phases during the transformation process. Notably, the introduction of OTC also inhibits the transformation process, potentially impacting the fate of other potentially harmful elements.

Prior to the experiments, three uniform silica sands, which were originally water-wet, were aged in contact with crude oil until they were moderately oil-wet. Five fractionally wet sands were obtained by mixing the water-wet sands with oil-wet sands containing 25, 50 and 75 vol% oil-wet sands. A total of 11 tests formed the basis for the present study. The measured water retention curves showed that the capillary pressure heads were greatly reduced in sands that were oil-wet or fractionally wet. Changes in the wettability of the sands also affected their irreducible water saturation: The higher the proportion of oil-wet sand in the sand mixtures, the lower the irreducible water saturation. To quantify the characteristics of the measured water retention curves, the Van Genuchten model was used. The two optimized parameters seem to indicate a general trend: The higher the volume fraction of oil-wet sand, the higher is <em>α</em> and the lower is <em>n</em>. For the three unaged sands and the aged medium-sized sand, it was found that each of the two branches of the measured retention curves can be suitably scaled to a unique curve if, in addition to the petrophysical parameters (intrinsic permeability, porosity, surface tension, gas-water contact angle), the irreducible residual water saturation and the residual air saturation are taken into account. To quantify the observed deviations of the other two aged sands from the unified Leverett J-function, a theoretical fit function was used to match the experimental data of the three unaged sands. The experimental data sets for P2040ag and P100ag were found to be overestimated overall by the fit function. However, when the petrophysical parameters of the unaged sands were used instead of the actual measured parameters, the individual experimental Leverett J-functions came closer to the uniform J-curve. Based on this, it could be concluded that the apparent differences in pore structure between aged and unaged sands in addition to wettability, expressed by the cosine of the contact angle, may have contributed to a further reduction in the capillary pressure plateaus of the aged sands, which was particularly visible and significant in the P2040 and P100 sand. Using the measured static contact angles for two-phase gas-oil and oil-water systems and the measured interfacial tensions when the porous medium is either water-wet or moderately oil-wet, it was shown that the Bartell-Osterhof equation overestimates the measured gas-water contact angles. Reasonable agreement was achieved when a calibrated roughness factor of the solid surface was considered in the Young's contact angle.</div></div>","PeriodicalId":15530,"journal":{"name":"Journal of contaminant hydrology","volume":"269 ","pages":"Article 104502"},"PeriodicalIF":3.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143006379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
