Saline formations are considered to be candidates for carbon sequestration due to their great depths, large storage volumes, and widespread occurrence. However, injecting carbon dioxide into low-permeability reservoirs is challenging. An active demonstration project for carbon dioxide sequestration in the Ordos Basin, China, began in 2010. The site is characterized by a deep, multi-layered saline reservoir with permeability mostly below 1.0×10-14 m2. Field observations so far suggest that only small-to-moderate pressure buildup has taken place due to injection. The Triassic Liujiagou sandstone at the top of the reservoir has surprisingly high injectivity and accepts approximately 80 % of the injected mass at the site. Based on these key observations, a three-dimensional numerical model was developed and applied, to predict the plume dynamics and pressure propagation, and in the assessment of storage safety. The model is assembled with the most recent data and the simulations are calibrated to the latest available observations. The model explains most of the observed phenomena at the site. With the current operation scheme, the CO2 plume at the uppermost reservoir would reach a lateral distance of 658 m by the end of the project in 2015, and approximately 1,000 m after 100 years since injection. The resulting pressure buildup in the reservoir was below 5 MPa, far below the threshold to cause fracturing of the sealing cap (around 33 MPa).

Suitability study of groundwater for domestic and irrigation purposes was carried out in the middle Subarnarekha river basin, Jharkhand. Collected samples were analysed for physicochemical parameters such as conductivity, total dissolved solids (TDS), pH, and heavy metals. After the physicochemical analysis groundwater samples were categorised for simplicity, accordingly, it shows that 52.6% samples fall in Ca-Cl2, 33.3% in Ca-HCO3, 10.5% in Ca-SO4, and 1.7% samples in Mg-HCO3 and rest were Na-Cl type. Interpretation of hydro-geochemical data suggests that leaching of ions followed by weathering and anthropogenic impact (mainly mining and agricultural activities) control the chemistry of groundwater in the study area. The TDS concentration at Govindpur site varies from 2677 mg L1 in the pre-monsoon to 2545 mg L1 in the post-monsoon season that is higher than the BIS (2004-05) maximum permissible limit (2000 mg L1 ). The elevated concentration of NO3 was identified at Govindpur, Hatia Bridge, Kandra, Musabani, Saraikela, Mango and Tatanagar. The higher NO3 concentration was due to the action of leaching and anthropogenic activities. At most of sampling locations, the concentration of Cd, Pb, and Ni were found higher than the prescribed limits defined by BIS and WHO. Groundwater suitability for drinking purpose was also evaluated by the synthetic pollution index (SPI), it suggests that 74%, 95%, and 21% samples fall in seriously polluted category during pre-monsoon, monsoon, and post-monsoon season, respectively. The calculated values of SAR, Na%, RSC, PI, and MH have shown that except at few locations, most of groundwater samples are suitable for irrigation purposes.

COVID-19 has changed the permeability of borders in transboundary environmental governance regimes. While borders have always been selectively permeable, the pandemic has reconfigured the nature of cross-border flows of people, natural resources, finances and technologies. This has altered the availability of spaces for enacting sustainability initiatives within and between countries. In Southeast Asia, national governments and businesses seeking to expedite economic recovery from the pandemic-induced recession have selectively re-opened borders by accelerating production and revitalizing agro-export growth. Widening regional inequities have also contributed to increased cross-border flows of illicit commodities, such as trafficked wildlife. At the same time, border restrictions under the exigencies of controlling the pandemic have led to a rolling back and scaling down of transboundary environmental agreements, regulations and programs, with important implications for environmental democracy, socio-ecological justice and sustainability. Drawing on evidence from Southeast Asia, the article assesses the policy challenges and opportunities posed by the shifting permeability of borders for organising and operationalising environmental activities at different scales of transboundary governance.
