SAMPLING DATE 08-04-2008  NUNBER OF SAMPLES 5 Samples supplied by client | SAMPLE TYPE:SOIL SAMPLE FOR ACID SULFATE STUDY
DATE RECEIVED 19 AUGUST 2008 PACKAGING SAMPLES LABELLED - INTACT Ground Oven Ory Samples DISPOSED ON 1/5/2009

Sample ID ag received. METHODOLOGY: As per (ONR GASSIT May 2004), oven dried (85/C), 71000 um shell removed, fine grind. All reported values gravimetric, dry mass.

LIME1 rates calculated to neutralise TPA (or TAA if >TPA)+ aS_RAS -ANC_E/1.5 LIME2 rates calculsted to neutralise TAA + aS_POS or S Cr + aS_RAS -ANC_8T/1.5

W9. Line rates assume 97% lime neutralisation but DO NOT include any safety factors. Suggested factor=1.5-2. Rates are kg/ton. Multiply by bulk density to convert to kg/m.
Fineness Factor=1.5 C&W POS: moles carbonate alkalinity released by oxidation assuming (Ca POS - Ca KCL) + (Mg POS - Mg KCL) is due to carbonate solution.

Slanks represent unmeasured vaiues, zeros & <O.x represent measured values. 1f pH KCl>4,5 then s-RAS (calculated from acid extract) may be zero for undisturbed soit. Ca NAS is the
acid reactive calcium catcutated as the difference between 1 4 KCL and 4 M HCL soluble Ca.
