Groundwater From Sauk County’s 100SDGV Aquifer and Its Role in Home Water Supply

The water feeding homes in Sauk County often comes from the 100SDGV aquifer, a source monitored by the U.S. Geological Survey. Wells ranging in depth from 50 to 185 feet tap this aquifer to supply groundwater. This source passes through geological formations that can influence certain minerals present before the water reaches household taps.

The Impact of Sampling Depth and Well Characteristics on Expected Manganese Levels

Sampling of wells within this aquifer reveals manganese concentrations detected at different levels depending on well depth and location. Deeper wells might encounter varying manganese levels compared to shallower ones because of geological differences and water movement patterns. Consequently, a household's water manganese content depends on the specific well characteristics, not just the general range found in the area.

Recording Household Water Information Before Exploring Treatment Options

Before considering water treatment equipment, it is important for homeowners to note details about their water source, including well depth, date of any recent water tests, and visual or taste changes observed in the water. This information helps clarify if manganese is a potential concern for the specific household or if other factors influence water quality.

Evaluating Treatment Capacity in Relation to Daily Household Water Use

When selecting a manganese treatment system, the daily volume of water used in a household must be matched with the system’s capacity to process water effectively. Water usage varies widely between homes, so treatment equipment should be suited to handle peak and average daily demand without compromising manganese reduction efficiency.

Understanding Manganese Levels Compared to Federal Guidelines and Their Interpretation

The U.S. Geological Survey sampled 28 results from three wells in Sauk County’s 100SDGV aquifer, with manganese detected in 10 results and mostly below measurable limits in others. The manganese levels ranged from 0.2 to 410 micrograms per liter, with a median of 0.285 micrograms per liter. Importantly, none of these results exceeded any federal manganese standard. This indicates manganese is present in varying but generally safe concentrations in the area’s groundwater, though this does not guarantee individual wells mirror these exact figures.

How Manganese Enters Groundwater in Sauk County and Affects Residential Water

Manganese occurs naturally in the earth’s crust and can dissolve into groundwater as water passes through mineral deposits and soil layers. In Sauk County, this process leads to variations in manganese concentration based on aquifer geology and well location or depth. Manganese itself is not a health hazard at levels found in this aquifer but can influence water appearance and taste.

Consequences of Untreated Manganese Over Time in Household Water

Over prolonged periods, manganese in water can cause stains on plumbing fixtures, laundry, and appliances. It might also impart a metallic taste or darken water clarity. These effects are aesthetic and operational concerns rather than direct health risks at levels observed in the local aquifer.

Confirming Your Water’s Manganese Level With a Professional Test

The definitive way to understand manganese levels in your household water is through laboratory testing of a water sample from your specific well or tap. This test will determine if manganese concentrations require treatment and help select an appropriately sized treatment system. One available option designed to address manganese in residential water is the Pentair Black Manganese Stains Filter, which ships ready to configure to meet household demand.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2019-05-15. These figures describe groundwater sampled in this area. They are not a test of any individual private well - only a test of that well can establish its own water.

On record: U.S. Geological Survey sampling of Manganese in the 100SDGV aquifer (Sauk County): 28 results from 3 wells, median 0.285 ug/L, range 0.2-410.0 ug/L; none above any federal threshold
