Abstrakt: The characterisation of solid waste (SW), leachate, is essential for developing an appropriate management strategy or treatment method. However, due to a range of contributing factors, such as waste type and dumping site locations, forecasting leachate quality is often challenging. This research article discusses leachate quality indicators and the temporal variations of leachate quality collected throughout various seasons and after 1-2 years of storage. In addition to that, the article also provides the data of different physicochemical parameters of SW and ground water (GW) quality collected from of Pirana solid waste dumping area (Pirana SWD), Ahmedabad, India, and surrounding areas throughout various seasons. The parameters like pH, COD, TDS, sulphates, nitrates, ammonia nitrogen, hardness, and heavy metals were all monitored to see whether there any temporal variations. When leachates were obtained 'fresh,' all parameters evaluated showed significantly higher values. As time passed, the values of the parameters (COD, ammonia nitrogen) stabilised. Heavy metals such as Hg, As, Pb, and Cr were detected in both fresh and old samples. Similarly in SW, the presence of heavy metals Hg (0.39 ppb), Pb (1.12 ppb), and Cr (16.86 ppb) were also detected. In case of GW, some samples also show the high TDS but the presence of metals like Cr, Ni, and Zn is less than permissible limit.
