Water quality refers to the chemical, physical, and biological characteristics of water that determine its suitability for various uses, including drinking, cooking, bathing, and commercial purposes. Maintaining high water quality is crucial for protecting public health and the environment. Poor water quality can lead to health issues, illness, contamination, and deterioration of household appliances.  For well owners specifically, the Environmental Protection Agency (EPA) and Department of Environmental Protection (DEP) recommend having your water tested at least one time per year as levels and contaminants can vary over time.
