Scientific Investigations Report 2007–5075

Table 1. Construction and water-level data for drive-point wells installed at the former sewage lagoon, Naval Air Station Whidbey Island, Washington, June and August 2006.

[Latitude and longitude coordinate information is referenced to the North American Vertical Datum of 1983 (NAD 83). Altitude is referenced to National Geodetic Vertical Datum of 1929 (NGVD 29). Symbol:, –, water levels could not be measured. Abbreviations: dms, degrees minutes seconds; ft, foot; in., inch]
