Well Water in Alcona County: What to Test and Why

Your well draws water from the Marshall aquifer, a layer of old sandstone buried deep underground. This rock is firm and dense, with tiny pores that hold water. The sandstone stretches across several counties in this part of Michigan and acts like a natural filter as water moves slowly through it.

Lead shows up in some Alcona County wells, likely from old plumbing in homes rather than from the rock itself. The sandstone is not the source of the problem. Arsenic and chloride are also detected, but they come from the rock naturally as groundwater dissolves minerals over time. The geology does not protect against these contaminants the way harder rocks in neighboring areas do.

The water here is extremely hard and salty. You will notice buildup on faucets and pipes, and your soap will not lather well. The high iron, sodium, and sulfate mean the water tastes and feels different from softer water. Testing your well is the first step to understand what you are dealing with.

Lead is found at levels that exceed EPA health standards in some Alcona County wells. Testing shows this is a real concern worth addressing. Arsenic also appears in local groundwater and warrants testing. The good news is that both contaminants are showing up at low urgency levels in your area.

Your water carries extremely high levels of iron, sodium, sulfate, and hardness. Long-term exposure to this mineral-rich water will stain your sinks, toilets, and laundry orange or rust-colored. You'll also notice scale buildup on pipes and faucets that clogs them over time. The water will taste salty and may have a rotten egg smell from the sulfate.

Get your well tested through a state-certified lab right away. A basic health screen for bacteria and nitrate runs fifty to one hundred dollars. A comprehensive test for metals and minerals runs two hundred to four hundred dollars. Ask the lab to test for lead, arsenic, iron, sodium, and sulfate so you know exactly what you're dealing with.
