The volume of waste water generated by domestic, industrial and commercial sources has increased with population, urbanization, improved living conditions, and economic development. The productive use of wastewater has also increased, as millions of small-scale farmers in urban and peri urban areas of developing countries depend on wastewater or polluted water sources to irrigate high- value edible crops for urban markets, often as they have no alternative sources of irrigation water. Wastewater use for the irrigation purpose has been well documented but still there are loopholes in the study to monitor the effects of municipal wastewater on environment and its suitability for agriculture. Hence, the present investigation was primarily aimed at determination of agriculturally significant physico-chemical parameters of IARI sewage wastewater and industrial wastewater from CETP, Mayapuri and compared their pollution strength, primarily in terms of BOD, COD, TDS, heavy metals and nutrients (N, P, K). The treated wastewater from CETP, Mayapuri has very excellent prospective for irrigation as the most agriculturally significant physico-chemical parameters are under the general standards of FAO guidelines and indicate fairly out of harm's way for the use in irrigation. However, the sewage wastewater of IARI was not safe and sound and required further amelioration before its utilization in irrigation. The TDS of the IARI wastewater was in the range of 1938 – 2220 ppm. The lead (Pb) concentration was also in the range of 0.04 to 3.84 which is higher side and must be remediated before its utilization to the leafy vegetable crops. Moreover; the wastewater of CETP was tertiary treated while the wastewater of IARI was only preliminary treated. |
