These non-invasive geophysical data sets can be used to optimize the design of multi-borehole groundwater monitoring stations along bedrock river channels, such that angled boreholes could be emplaced and orientated to intercept major fracture networks and local dissolution features.
GOT, groundwater observation station of the Geological Survey of Japan, AIST; TNH, tilt station of the Japan Meteorological Agency (JMA); HGW, MTK, OTK, and TKN are GNSS observation stations of the Geospatial Information Authority of Japan (GSI).
It was found that the groundwater from the stations W1, W25 and W26 is unfit for irrigation.
It can be observed that out of 67 groundwater quality data points 24 stations (35%) fall in the "excellent" category, 16 stations (23%) in "good" category, 18 stations (26%) in "poor" category, 7 stations (10%) in "very poor" category and 3 stations (4%) in unfit category for pre-monsoon season.
Wave parameter for seismic event to station of groundwater and seismograms were also identified as 3.0 3.5 km/s and 64 110 km for wave velocity and wave length, respectively.
Other VES stations have appreciable groundwater within the weathered layer but because of high reflection coefficient (>0.8) which indicates that the basement beneath is fresh, it might not harbor or store adequate or sufficient groundwater, the borehole, when drilled might not be productive enough.
The list of data collection stations includes 213 groundwater, 10 surface water, 133 water quality and one meteorological station located throughout the five boroughs and in parts of western Nassau County on Long Island.
A number of sources sometimes considered important, such as petroleum refining operations, petrochemical manufacturing, oil storage tanks, urban-industrial areas, service stations, certain foods, groundwater contamination, and underground gasoline leaks, appear to be unimportant on a nationwide basis.
The coupling of pre-earthquake anomalous phenomena between long-term groundwater levels recorded at 42 monitoring stations and time-varying surface strain derived from 16 GPS stations was found in the Choshuichi Alluvial Fan before the 1999 Mw 7.6 Chi-Chi earthquake in Taiwan.
Two Farmingdale environmental firms and two of their owners have been ordered to pay $2.2 million in punitive damages to a Valley Stream gas station owner for covering up their failure to properly clean up a gasoline spill at his station that contaminated groundwater in the area.
