Then, in the worst case, the water would have moved through a connecting track, and like liquid moving through a Krazy Straw, the Harlem River would have flowed south through another under-river crossing, the Harlem River-Jerome tunnel, to 125th Street in Manhattan.
Installation of a drift eliminator, even in the worst case, reduces the water drift level to less than half of the situation without the eliminator.
These sites were chosen because subsurface geology and previous monitoring of nitrate, ammonia and chloride levels in shallow ground water strongly indicated direct infiltration, and as such represent worst cases for ground water contamination by waste water.
CSIRO cites a worst case of 20% less water in 20 years and 50% in 50 years.
In the worst case scenario, Priscu says, "water could come up the hole and degas explosively, blowing out the whole borehole".
Impedance matching networks were built, taking into account the matching for a 100%, 50% and, also, for the worst case of 0% of water fraction where there is a significant signal attenuation.
The modelling assumes two scenarios: a worst case scenario where drinking water concentrations are characterised at the highest concentration detected at the site; and a scenario where the concentrations found at each site are averaged using a root mean square conversion.
We took an estimated range of water use per well between 8000 and 19,000 m, and assumed that in the best case scenario, 70%% of flowback water would be recovered, of which up to 70%% could be recycled, meaning an overall re-use of 49%% of water in the worst case scenario, we assumed all water to be lost directly to the environment.
Decades after one of the worst cases of drinking water contamination in U.S. history, thousands of affected Marines and family members may finally receive health care.
Gatherer said it was highly unlikely to reach the "worst case scenario" of the 1998 Sydney water crisis, when traces of cryptosporidium and giardia were found in water between July and September in several major surburban areas.
The viscosity of the pooled contaminated challenge fluid also represented a worst case scenario as it was water-like and lower than proteinaceous sputum.
