Some specific criteria for rapid risk assessment of landfills [16].

SI. no.	Attribute (site-specific criteria)	Attribute weightage	Sensitivity index
			0.0–0.25	0.25–0.5	0.5–0.75	0.75–1.0
1.	Distance from nearest water supply source (m)	69	>5000	2500–5000	1000–2500	<1000
2.	Depth of filling of waste (m)	64	<3	3–10	10–20	>20
3.	Area of dumpsite (ha)	61	<5	5–10	10–20	>20
4.	Groundwater depth (m)	54	>20	10–20	3–10	<3
5.	Permeability of soil (1 × 10^−6 cm/s)	54	<0.1	1–0.1	1–10	>10
6.	Groundwater quality	50	Not a concern	Potable	Potable if no alternative	Nonpotable
7.	Distance to critical habitats such as wetlands and reserved forest (km)	46	>25	10–25	5–10	<5
8.	Distance to the nearest airport (km)	46	>20	10–20	5–10	<5
9.	Distance from surface water body (m)	41	>8000	1500–8000	500–1500	<500
10.	Type of underlying soil (% clay)	41	>50	30–50	15–30	0–15
