Appendix 2B. Field measurements and concentrations of inorganic constituents from groundwater and surface-water samples, seep 3-4W reactive mat pilot-test area,

 West Branch Canal Creek, Aberdeen Proving Ground, Maryland, February-August 2005

[ μS/cm, microsiemens per centimeter at 25oC; mg/L, milligrams per liter; μg/L, micrograms per liter; <, less than; '--, no data; NR, not reported by lab by time of publication, an 'E' indicates an estimated concentration

Note: Dates and times for a sample may not match field value table because low-producing wells were often sampled for inorganic constituents at later times or dates, Field pH, Specific Conductance, Water temperature, and Alkalinity samples for low-producing piezometers may have been collected earlier, or on a previous day (see Appendix 1), O-Deleted, not enough water for analysis; U-deleted, unable to determine due to interference; NR,not reported]
