Discoloration of water can occur when above-average levels of iron and manganese are present in our raw water sources: Long Creek and the reservoirs at Arrowood Lake and Webber Lake. Iron and manganese are naturally occurring minerals that typically increase during the fall and spring months.
The City works continuously with the North Carolina Department of Environmental Quality (NCDEQ) to evaluate and optimize our water treatment process to minimize discoloration.
Although the water may appear discolored, it remains safe for consumption and everyday use.
Manganese is commonly found in both ground and surface water. It enters the water naturally through soil erosion, especially during periods of drought, flooding, or heavy rainfall. It can also form from decomposing organic matter such as leaves and mulch. A common seasonal event known as lake turnover, which occurs in the spring and fall when water temperatures change, can also increase manganese levels. During turnover, deeper water layers rise to the surface, bringing naturally occurring minerals with them.
Heavy rainfall events can also lead to increased erosion, which contributes to elevated levels of iron and manganese in our creeks, lakes, and reservoirs.
