Coal is a domestically available resource that China has relied on to fuel its rapid industrial and economic growth. Nearly 90 percent of the country's coal resources are in northern China where coal-based industries have also developed. With this industrial growth comes heavy environmental impact, especially on the region's water supply, which is evident in the drying of aquifers and the escalating pollution level of fresh water sources. The government is acting to improve the region's precious water resource and is progressively enacting tighter regulations on water use and water discharge. These regulations are forcing industrial plants to implement wastewater recovery and reuse systems, which, in some cases, recycle 100 percent of the water with no discharge.
