Residents in Whatcom County rely on aquifers as their source for well water, with groundwater drawn from depths typically between 4 and 24 feet. The water quality in these local wells reflects aquifer conditions as measured by government monitoring, not the specific water in any single household well.
If you observe seasonal or multi-year variation in total dissolved solids:
Sampling collected by the U.S. Geological Survey from 33 wells in Whatcom County in November 2013 showed total dissolved solids (TDS) values ranging broadly from 0.17 to 797.0 tons per acre-foot. The median value recorded was 64.04 tons per acre-foot. These TDS levels can fluctuate over time due to factors such as rainfall, aquifer recharge, and seasonal water usage patterns. Recognizing this variability is important for understanding when and why water quality changes may occur within the area’s aquifers.
If you observe total dissolved solids near or above the secondary standard threshold:
The federal secondary standard for total dissolved solids is 500 mg/L, a threshold related to water aesthetics like taste and mineral staining. In the Whatcom County samples, 7 out of 66 readings were above this guideline. It is critical to note that exceeding this secondary standard is not a violation or safety risk but indicates potential for taste or staining issues. Only a water test of your specific well can determine your household’s TDS concentration and whether treatment is needed.
If you notice household symptoms that may or may not indicate elevated total dissolved solids:
Common signs linked to increased TDS include slightly salty or metallic taste and visible mineral deposits on plumbing fixtures or appliances. However, some symptoms often attributed to TDS—such as discoloration caused by iron or bacterial growth—do not directly correlate with total dissolved solids and require separate investigation.
If you need a solution that effectively addresses total dissolved solids:
The Fleck Complete Well System offers a comprehensive approach to reduce total dissolved solids from well water. This system uses technology designed to target and reduce the mineral content that contributes to elevated TDS levels. It is rated with a grain capacity of 32,000, indicating its capability to handle significant mineral loads over time. The system ships ready to configure for connection to your water supply.
If you want to protect specific fixtures and appliances first:
Fixtures such as faucets, showerheads, and water-using appliances like dishwashers and water heaters are usually impacted earliest by elevated total dissolved solids. Minerals may accumulate leading to staining and reduced efficiency. Early treatment helps extend the longevity and performance of these household components.
It is important not to conclude that area-wide government water quality figures directly predict your well’s condition. Only a professional water test on your household supply can establish the precise water quality you experience. Using regional data helps guide equipment decisions but does not replace testing your own water before choosing treatment options.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2013-11-14. 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 Total dissolved solids in the aquifer (Whatcom County): 66 results from 33 wells, median 64.04 tons/ac ft, range 0.17-797.0 tons/ac ft; 7 above an AESTHETIC secondary standard only (secondary standard 500.0 mg/L (aesthetic)) - not a health finding
