Groundwater in Roanoke city contains manganese, iron, and lead at levels that exceed EPA health standards. These contaminants are present at concentrations serious enough that well owners should take action to address them.
The bedrock beneath Roanoke is carbonate rock like limestone, which naturally contains iron and manganese. As water moves through this rock, these metals dissolve and enter the groundwater. Lead typically comes from plumbing materials in older wells and homes rather than from the rock itself, so it is more variable from well to well.
Groundwater in Roanoke is hard, driven by elevated calcium and magnesium from the limestone below. The carbonate rock dissolves slowly as water passes through it, releasing these minerals into the water. Hard water is the norm across wells in this area.
Wells in Roanoke city commonly have iron, lead, and manganese at levels above EPA health standards. Iron can cause problems with your blood and organs if you drink water with too much of it. Lead is especially harmful to children and can affect their brains and learning. Manganese can damage your nervous system over time with long-term exposure.
The hard water in county wells can create visible staining on your sinks, tubs, and fixtures. You might see reddish or brown discoloration from iron buildup. Hard water also makes it harder for soap to work well, and it can leave scale inside pipes and water heaters. Over time, very hard water can shorten the life of your dishwasher and water heater.
Every well is different, and your water could have higher or lower levels than what is common here. Testing is the only way to know what is actually in your well so you can treat it correctly. We recommend a comprehensive panel that checks for metals and minerals, which usually costs between two hundred and four hundred dollars. Water softeners and iron filters are common treatment options for the mineral concerns in this area.
