Drinking Water Quality
Beaver Water District must meet national, health-based standards for drinking water in order to fulfill its primary mission, which is to produce safe, potable water. That means the District must comply with the Safe Drinking Water Act (SDWA), passed by Congress in 1974 and amended in 1986 and 1996. The SDWA’s purpose is to protect public health by regulating the nation’s public drinking water supply.
The SDWA authorizes the U.S. Environmental Protection Agency (USEPA) to set standards for drinking water in order to protect against naturally occurring and man-made contaminants. The standards set enforceable maximum contaminant levels and provide the framework for accepted methods to treat water to remove contaminants. In Arkansas, USEPA’s requirements for the SDWA are managed and enforced by the Arkansas Department of Health. To comply with these standards, the District frequently tests water at various phases of the treatment process and monitors water before it leaves the facility on its way to customers. At every step, safeguards ensure that all standards are met and that the District is in compliance with the SDWA. Beaver Water District prepares an annual report each year.

Process Water Standards
In addition, the Arkansas Department of Environmental Quality (ADEQ) regulates BWD’s waste process water discharge and the land application of residual solids from the treatment processes pursuant to a National Pollutant Discharge Elimination System (NPDES) permit and a state General Permit for the land application of WTP solid residuals. BWD has a recently completed state of the art $11.7 million solids handling facility for the treatment of our waste process water and residual solids. This solids handling facility includes two solids contact clarifiers, a gravity thickener and three centrifuges for mechanical dewatering of the residual solids. The NPDES permit is a requirement of the federal Clean Water Act.
