Climate change can affect the intensity and frequency of precipitation. Warmer oceans increase the amount of water that evaporates into the air. When more moisture-laden air moves over land or converges into a storm system, it can produce more intense precipitation - for example, extreme rainfall causing stormwater and flooding events. Stormwater has implications for urban and rural planning, including new rainwater management strategies, advanced transportation infrastructure, and building components, as it cannot infiltrate the ground, causing flooding in developed areas and $billions in damages to our society. It can also gather pollutants, causing adverse effects on lakes, streams, and groundwater or polluting sources for drinking water. A class of chemicals contaminating water sources can be perfluoroalkyl- and polyfluoroalkyl substances (PFASs). Known as forever chemicals, this group of fluorocarbons accumulates continuously in water, soil, and the atmosphere due to their longevity. In humans, PFAS attributes are cancerous, liver-toxic, weakening the endocrine and immune systems of women, and teratogenic properties of men. Health Canada addresses this contaminant in its Canadian Drinking Water Quality Guideline 2024: ‘The lower the levels of exposure to PFAS, the lower the risk to public health, and advises treatment plants to strive to maintain PFAS concentrations as low as reasonably achievable.

Geological on-site assessments are key in determining the time and cost requirements and the feasibility of any tunnel construction project. Success critical factors are the development of a strong understanding of soil materials and rock formations, including the identification of geological fault zones affecting tunnel excavation efforts. Measurement data on groundwater, water-bearing rocks, and seismic activity are critical in preventing water intrusion or methane gas emissions into tunnel sections. Therefore, any new tunnel is to be designed earthquake-proof and requires an in-depth geological analysis before the project starts.
