Abstract

This research aims to investigate physical, chemical and biological characteristics of water from bamboo, and to compare bamboo water quality with groundwater quality standards for consumption, water supply quality standards of metropolitan waterworks authority, and water quality standards in sealed containers. Bamboo water was conducted from 4 species including Dendrocalamus asper, Bambusa burmanica, Bambusa beecheyana and Bambusa striata. In each bamboo species was collected for 4 replicates. The research found that color, odor, turbidity, pH, total hardness, chloride, nitrate, fluoride, iron, copper, zinc, arsenic and coliform bacteria of 4 bamboo water species were passed the criteria complied with 3 types of water quality standards. However, total solids and total dissolved solids of 4 bamboo water species were approximately 3 times greater than those of water quality standards in sealed containers and 2 times higher than those of groundwater quality standards for consumption. Manganese contents of 4 bamboo water species were over those of 3 types of water quality standards. Lead contents of 4 bamboo water species were over those of the water supply quality standards of metropolitan waterworks authority. Escherichia coli was found in all bamboo water species. The bamboo water quality may depend on soil, surrounding environment and preservation.
