Answer:
Potential sources of pollution included cowsheds, fertilizer and surface water sources. A minority of tubewells (38%) had a platform, with a median area of 2·8 m2 (0·8–5·9). Twenty per cent of these platforms were in a poor condition or cracked, 28% were dirty and 19% were undercut by erosion.
