Comprehensive Assessment Program for Enterprises with High Potential of Heavy Metal Water Pollution in Southern Region

Absrtact
This project focused on enterprises with Continuous Water Monitoring System (CWMS) in southern region, polluted agricultural lands or irrigated lands in upstream, and high-pollution-potential industries in non-designated industrial zones. Five pollution hotspots were identified by overlaying these spatial data. This project selected 22 enterprises as pre-warning targets by the criteria of "violation rate of the Water Pollution Control Act over 15% in the past 5 years." Furthermore, nine enterprises were recommended by the authorities due to high potential risks. Therefore, there were a total of 30+1 pre-warning targets. After multiple inspections, discussions, and evidence collection with the authorities, 10 enterprises were selected for in-depth audits. This project has completed in-depth audit of a total of 10 enterprises this year, and seized three enterprises with "serious violations": (1) 日○ company, a steel company, was found discharging untreated wastewater through an unauthorized discharge outfall, regarded as rerouted discharge and violated Article 18-1, Paragraph 1 of the Water Pollution Control Act. (2) 連○ company, a leather factory in Hunei, exceeded the discharge limit, with pollution concentrations five times higher than the standard, regarded as "serious violation." (3) 慧○ company exceeded discharge limit, with pollution concentrations five times higher than the standard, regarded as "serious violation." The project held a discussions and practical on-site training on May 12, 2023 and an interdisciplinary workshop of reusing of waste liquid crystal glass in wastewater treatment on September 20, 2023, and an experience-sharing activity to exchange opinions and share on-site inspection experiences on October 25, 2023. The project shared audit results by using various scientific tools to collect evidence based on possible illegal patterns for various enterprises, and provided three video recordings of audit results, to complete the contract requirements with 100% of completion rate.
