Clearance of sludge has made a major task in latest periods. In the current study sludge from KPRWTP were investigated concerning physicochemical characteristics & disposal options. Organic content of petroleum sludge & clay soil was 0.23 ±0.09% and 0.186±0.1%, respectively. Metals average concentration: Chromium: 130.95±27.32 mg/kg Arsenic: 0.899±0.434 mg/kg lead: 47.83±21.44 mg/kg Cadmium: 18.33±9.04 mg/kg Copper: 209±31.18 mg/kg Zinc: 631±159.57 mg/kg Nickel: 6.6±2.44 mg/kg cobalt: 35.54±10.08 mg/kg manganese: 35.54±10.08 mg/kg: iron: 501±5490.04 mg/kg: titanium: 108.3±18.33 mg/kg, and zirconium: 2.54±0.246 mg/kg respectively. Sludge was made up of particles to some extent of bigger portion compared to soil (sludge: clay and silt 58.9%, sand 41.1% soil: clay and silt 76%, sand 34%). Core constituents of petroleum sludge were Fe2O3 (38.45%), SiO2 (8.55%), CaO (30.35%), MgO (0.85%). According to standards of (NJDEPSCC) As, Cd, Cu, Pb, Ni, & Zn have significantly lower concentration in sludge comparing guideline for residential and nonresidential utilization. On the other hand, FDEPSCTL showed Cu and Zn were only metals in sludge significantly have high concentration regarding guideline for residential applications only. The study confirmed that heavy metals under investigation were significantly lesser than quantities controlled by (TCLP) of (RCRA), with exception for chromium content.
