    Arsenic in Your Water

    Renewed

    Arsenic in your drinking water poses a threat to your health. Since private systems are more susceptible to arsenic than public water systems, private well owners should take steps to guard their health. Measures include routine water supply testing and wellhead maintenance and protection.

    Water Quality and Common Treatments for Private Drinking Water Systems

    An abundant supply of clean, safe drinking water is essential for human and animal health. Water from municipal or public water systems is treated and monitored to ensure that it is safe for human consumption. Many Georgia residents, especially in rural areas, rely on private water systems for human and livestock consumption. Most private water systems are supplied by wells. Water from wells in Georgia is generally safe for consumption without treatment. Some waters, however, may contain disease-causing organisms that make them unsafe to drink. Well waters may also contain large amounts of minerals, making them too “hard” for uses such as laundering, bathing or cooking. Some contaminants may cause human health hazards and others can stain clothing and fixtures, cause objectionable tastes and odors, or corrode pipes and other system components.

    Understanding the Potential Impacts of Utility-Scale Solar Facilities on Groundwater and Surface Water in Georgia

    Georgia is experiencing rapid growth in utility-scale solar energy development. This resource addresses some general concerns and questions residents have asked UGA Extension about how the construction and operation of these solar facilities could affect our soil and the quality of our shared surface and underground waters, including well water.

    Drinking Water: Interpretation and Recommendations

    An estimated 1.7 million people in Georgia rely on 640,000 private wells for their drinking water supply, and private well water users are responsible for ensuring the quality and safety of their water supplies for domestic, livestock, and irrigation use. This online tool provides interpretations and recommendations for drinking water quality.

    Iron (Manganese) and Sulfur Bacteria in Your Well Water

    Bacteria in your drinking water supply do not necessarily pose a health hazard, but they can be a nuisance. The two most common types of nuisance bacteria are iron (manganese) and sulfur bacteria. Iron bacteria are generally more common than sulfur bacteria because large amounts of iron can be present in ground water. You can typically confirm the presence of iron bacteria through visual inspection. The unmistakable “rotten egg” odor of hydrogen sulfide gas is the most obvious sign of a sulfur bacteria problem. This resource includes some simple preventive measures as well as control and treatment options.
