Groundwater can be categorized into several groups based on its usage; potable household water, non-potable household water, agricultural water, industrial water. This categorized water can only be used when it meets the appropriate standards. Also, anyone who is willing to use the groundwater should report to or get permission from the authorities. KOTITI researchers offer the best analysis services as authorized Drinking Water Inspection Agency designated by the Ministry of Environment.
