The Baddi, Barotiwala and Nalagarh (BBN) in Nalagarh tehsil of Solan District has witnessed rapid industrialization since 2003 when the BJP led government at the Centre announced an industrial subsidy package for the state. Since then an investment of over Rs 4260 crores, into over 3950 registered industrial units has happened. A large number of the units here are polluting in nature, like pharmaceuticals, chemicals, plastics, dying and boilers. Heavy extraction of ground water, ground water pollution, toxicity in air, fly ash and hazardous waste dumping have been the key problems that have arisen in a stretch of almost 35 kms with 21 Panchayats and 115 villages being affected.
