How Selenium Enters Groundwater in Oakland County's Aquifer 112OTSH
Selenium Originates from Natural and Human Influences
Selenium occurs naturally in soils and rocks and can dissolve into groundwater as it moves through aquifer 112OTSH in Oakland County. It is also influenced by historical agricultural practices and possible industrial activities in the area. These factors together can introduce selenium into local wells without indicating any health or safety threat on their own.
What to Document Before Seeking Heavy Metals Treatment Advice
Obtain Your Well Water Test Specific to Selenium
Because government sampling reports area-wide selenium levels, your household should conduct a professional water test measuring selenium in your own well or tap. Document the exact selenium concentration reported, the well depth, and the testing date to support informed treatment decisions.
Note Any Changes or Symptoms Possibly Linked to Heavy Metals
Record household water characteristics such as taste, staining on fixtures, or plumbing issues that may relate to heavy metal presence. This information can assist in evaluating your treatment needs beyond lab results.
Maintenance Rhythm for the Fleck Heavy Metals Filter
Regular Cartridge or Media Checks Are Essential
The Fleck Heavy Metals Filter ships ready to configure and uses a filtration medium designed to reduce heavy metals like selenium effectively. To maintain performance, routinely check and replace filter media or cartridges as recommended, generally based on water usage and quality rather than fixed time intervals.
Monitor System for Flow Rate or Pressure Drops
Significant changes in water flow or pressure may signal the need for media refresh or cleaning. Keep a maintenance log for consistent performance tracking.
Sample Size and Well Depth Behind Oakland County Selenium Data
Area Sampling Covers 16 Wells Ranging 11 to 49 Feet Deep
U.S. Geological Survey data for aquifer 112OTSH in Oakland County includes 18 selenium measurements from 16 different wells sampled between 2010 and 2016. These wells vary in depth but concentrate within the upper 50 feet of the aquifer.
Sampling Reflects a Limited but Informative Snapshot
While the data shows selenium detected in 12 samples and below detection in 6, these numbers represent area trends rather than any one private water source.
Interpreting Median and Range Values as a Homeowner
Median Selenium Concentration Is 0.38 Micrograms per Liter
This median value indicates half of the sampled results were above 0.38 ug/L and half were below, within a range from 0.18 to 1.3 ug/L.
All Measurements Are Below Federal Thresholds
None of the selenium levels sampled in this area exceed federal drinking water standards, meaning detections alone do not imply health risks.
What Area Selenium Data Does Not Indicate About Your Household
These Results Are Not a Substitute for Individual Water Testing
Because water quality can vary greatly even within the same aquifer, the government’s area-wide selenium measurements do not reveal your well’s specific concentration.
Detection Does Not Equal a Problem or Violation
Detected selenium simply means it was measured by instruments. It is not an indication of unsafe water or regulatory noncompliance.
Your Existing Equipment May Need Support Beyond Its Capacity
If current treatment feels insufficient, the Fleck Heavy Metals Filter is designed to help reduce selenium and other heavy metals effectively when configured properly and maintained according to usage.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2016-09-27. 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 Selenium in the 112OTSH aquifer (Oakland County): 18 results from 16 wells, median 0.38 ug/L, range 0.18-1.3 ug/L; none above any federal threshold
