5.)Seal: Bentonite 0 to 10 and 0 to 189 were poured and tagged on the outside of the 16" casing. Cement was tremied from the bottom and calculated at approx 315 bags but only came up to 189' after 367 bags. Spoke with Jon SanFilippo (Inspector) and was ok to chip Bentonite to the surface. Poured & Tagged 10,000 pounds of Bentonite chips to the surface. 5.) Borehole: 12" Borehole was drilled to 905' but kept caving @ 780' Cemented once and still fell in so we pulled off.
