Rising groundwater threatens clean air and water across the US
Places in the United States where the water table is inching higher — along the coasts, yes, but also inland, in parts of the Midwest — are already beginning to experience problems with infrastructure. Cracks in aging and poorly maintained pipes are being inundated, leaving plumbing unable to carry away stormwater and waste. Pavement is degrading faster. Trees are drowning as the soil becomes soupier, starving their roots of oxygen. During high tides and when it rains, groundwater is even reaching the surface and forming temporary ponds where there never used to be flooding. … In the San Francisco Bay Area, rising groundwater threatens to spread contamination that can evaporate and rise into the air inside homes, schools, and workplaces.
