The electroplate industry and metal surface industry within changhua county are spreading out on agricultural lands. Due to the fact that the regional sewage systems can not function sufficiently, the irrigation channels and wastewater discharge systems are often intertwined. The wastewater containing heavy metals is thus discharged directly into the irrigation systems, resulting in the heavy metal pollution of farm lands. This project analyzes the production characteristics of electroplate and metal surface industries, “Standard procedures for factory inspection regarding electroplate and metal surface industries” is drafted. Three phases of inspection are carried, “Factory inspection and standard operational procedures analysis”, “Pollution evident collection by scientific monitors” and “The follow up strategies”. During the project period, 49 factory inspections and 40 standard operational procedure analyses were accomplished. Four major pollution cases and 15 cases against water pollution prevention law were found and properly punished. During the project period, the sources of pollution and how heavy metals affect the water bodies were investigated and analyzed. “The reduction project of heavy metal pollutants” was drafted. Five reduction strategies employed include prevention mechanism of heavy metal pollution, scientific monitoring methods for combating industries’ illegal activities, the cooperation of authorized agency for pollution prevention and verification, factorial environmental improvements and some other strategy. As for prevention of farm land pollution, “The heavy metal pollution prevention mechanism regarding electroplate and metal surface industries” was drafted. It is carried out by means of 24-hour continuous monitoring, monthly water sampling and unexpected factory inspections to effectively control and prevent potential pollution sources.
