Rising groundwater threatens New Haven

Some New Haven basements and underground utilities may be at risk of being inundated by rising groundwater by the end of the century due to projected rates of sea level rise for the area, according to a preliminary Yale study.

The report, produced in partnership by the U.S. Geological Survey and Yale University, indicates that a projected three-foot increase in sea level can be expected to increase groundwater levels in coastal areas, presenting long-term water management issues that could be very costly to mitigate.

Groundwater levels may rise even higher if groundwater recharge -- the rate at which water is added to groundwater through precipitation -- also increases.

In response to the study, Yale has been designing new building projects to accommodate the increases in groundwater levels anticipated in future years, said Yale spokesman Tom Conroy.

The report, is available online:
