CLIENT NAME Brett Egen c/o Douglas Partners Pty Ltd (Sunshine Coast) 28 Kessling Avenue Kunda Park 4556

PROJECT NAME 33 Wyuna Drv Noosaville YOUR PROJECT/JOB REFERENCE 95120

SAMPLING DATE NUMBER OF SAMPLES 4 Samples supplied by client SAMPLE TYPE:Soil/Solid

DATE RECEIVED 6/10/2020 5:11:39 PM PACKAGING Plastic Bag Ground Oven Dry Samples DISPOSED ON 5/12/2020

Sample ID as received. METHODOLOGY: As per (DNR QASSIT May 2004), oven dried (85°C), >1000 um shell removed, fine grind. All reported values gravimetric, dry mass.
%sEQ (equivalent sulphur) calculated as moles TAA/624 + %S Cr + %SNAS - sANC_BT (sNAS included irrespective of pH).
LIME1 rates calculated to neutralise TPA (or TAA if >TPA)+ aS_RAS -ANC_BT/1.5 LIME2 rates calculated to neutralise TAA + aS_POS or S_Cr + aS_RAS -ANC_BT/ 1.5

NB. Lime 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/m3.

Fineness Factor (FF)=1.5 CBN POS= moles carbonate alkalinity released by oxidation assuming (Ca POS - Ca KCL) + (Mg POS - Mg KCL) is due to carbonate solution.

Blanks represent unmeasured values, zeros & <0.x represent measured values. If pH KCl>4.5 then s-RAS (calculated from acid extract) may be zero for undisturbed soil.

acid reactive calcium calculated as the difference between 1 M KCl and 4 M HCL soluble Ca.
