Samples were collected after well stabilization occurred. Well stabilization was achieved when, for at least three consecutive measurements, the pH remained constant within 0.1 standard units and specific conductance varied not more than approximately 10%. Unable to collect samples from the well head due to no sample port at well. Samples were collected from the spigot on exterior of well house.
