Abstract
This study aimed to assess the water quality in Toro River and to analyze the status of pollution using the Storet method according to the regulation on quality standards in Minister of Environment Decree number 115 of 2003 and the quality standards of Minister of Environment Decree No. 179 of 2004. The research was carried out for 3 months from September to November 2022, in the Toro River, Toro Village, Bone Regency. Data was taken directly in the field consisting of water samples at 10 stations and soil sediments at 5 stations randomly. The results showed that the range of water quality parameter values observed were Ammonia 0.12-0.31 mg/L, Phosphate 0.0021-0.0082 mg/L, Nitrate 0.16-2.41 mg/L, Nitrite 0.0055-0.018 mg/L, Cd 0.001-0.013 mg/L, Pb 0 mg/L, Temperature 32.1-34.4oC, DO 2.48-8.14 mg/L, pH 6.33-8.14, salinity 3-25 o/oo, BOD 2-5.12, COD 6.96-81.69 mg/L, BOT 14.26-46.79 mg/L. Based on a comparison of data per parameter with water quality standards from Minister of Environment Decree number 179 of 2004, it shows that the Nitrate and Cadmium (Cd) parameters have exceeded the water quality standard thresholds. Based on the analysis of the Storet value system it was known that the waters of the Toro River are included in the class C category, namely moderately polluted with a score of -28. Pollution control in the Toro River needs to be done in order to maintain environmental conditions that are not polluted.
