N2  - The objective of this research was to evaluate the quality of the surface water and  soil in the Chini Lake watershed, including areas of agriculture and mining, and to  develop an integrated model for sustainable management of the region involving local  participants. To achieve this, samples of water were collected from ten preselected  sampling stations and analyzed between June 2017 and April 2018. Similarly, soil  samples were collected twice from 10 stations during the dry and wet seasons. Total of  24 water quality parameters included 10 heavy metals and soil properties, including ten  heavy metals, were examined using standard methods. Data analysis was performed using  statistical software (SPSS 22.0). Based on the WQI, all 24 water quality parameters and  ten heavy metals were classified under Class II, which included temperature, (EC), TSS,  TSS, DO, pH, BOD, COD, TP and AN were classified under Class II. Based on the  analysis that has been made, station at Jemberau and Chini River are classified as Class  III, which is according to index range of WQI, the station at Jemberau near the River and  Chini River was classified as slightly polluted. Based on the collected data for different  stations of water samples that has been analyzed, we can conclude that the main sources  of water pollution have come from nearby mining activity. The heavy metal  concentrations of ten parameters (Ba, As, Zn, Cu, Mn, Cd, Co, Cr, Pb, and Ni) were  analyzed using an ICP-MS test. The results showed that the heavy metal concentrations  in the water samples were low and categorized as Class I, despite rising during the rainy  season. The Water Quality Index (WQI) indicated that Chini Lake water was safe for  recreational use and body contact, as it was classified as Class II. Mining activity was not  the primary source of pollution in Chini Lake since heavy metal concentrations were low.  Instead, agricultural and logging activities contributed to water contamination in the  Chini watershed. The soil analysis revealed low organic matter, low pH, and low EC  levels. The ecological risk indices, such as geo-accumulation index (Igeo), contamination  factor (CF), and pollution load index (PLI), indicated that Cd and Zn concentrations were  higher in the mining area. Moreover, PLI was higher in the mining zone than in other  areas. Anthropogenic activities, including iron mining, agricultural, and industrial  activities, were the primary sources of water contamination. Two types of surveys were  conducted among three different groups. The Knowledge, Attitude, and Practices (KAPs)  survey was distributed to assess the knowledge, attitudes, and practices of local  community members and agriculture employees towards agriculture pollution. The  general survey was distributed to determine the willingness of authorities (DOE) to  collaborate with local community members and agriculture employees. The study found  that individuals who were older, had higher education levels, were long-term residents of  the community, and had years of work experience were the most observant of changes in  surface water and soil quality. The KAP survey scores indicated that local community  members had good knowledge, attitude, and practices towards environmental issues,  while agriculture employees had good knowledge and attitude but poor practices. All  three groups expressed interest in participating in collaborative efforts to protect the Chini  Lake watershed from contamination. The study's results suggest that an effective  implementation of a socio-scientific integrated approach by the authorities can be an  innovative solution for developing sustainable watershed management
