Every house of the city has access to the clean drinking water supplied by the municipal corporation during the regular periods of time every day. Due to small agricultural fields, the use of harmful chemicals such as pesticides is also very controlled in the city. Thus the water quality of the Chandigarh lies within the limits as prescribed by the BIS standards of drinking water. Water analysis conducted by the Central Ground Board of the shallow and deep aquifers of the city shows the absence of any impurity including heavy metals.
