Until independence, Armenia's economy was based largely on industry—chemicals, electronic products, machinery, processed food, synthetic rubber and textiles; it was highly dependent on outside resources. Armenian mines produce copper, zinc, gold and lead. The vast majority of energy is produced with imported fuel from Russia, including gas and nuclear fuel for Armenia's Metsamor nuclear power plant. The main domestic energy source is hydroelectric. Small amounts of coal, gas and petroleum have not yet been developed. Armenia's severe trade imbalance has been offset somewhat by international aid, remittances from Armenians working abroad, and foreign direct investment. Economic ties with Russia remain close, especially in the energy sector. Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment. Water treatment removes contaminants and undesirable components, or reduces their concentration so that the water becomes fit for its desired end-use. This treatment is crucial to human health and allows humans to benefit from both drinking and irrigation use. Sanitation refers to public health conditions related to clean drinking water and treatment and disposal of human excreta and sewage.
