Water Source and Local Aquifer Information

Household water in Berkeley County typically comes from wells drawing from aquifer 120FLRD, with well depths sampled ranging from 110 to 280 feet. Groundwater moves through this aquifer before entering home plumbing.

Additional Industrial and Commercial Questions

What different concerns do commercial operators have about acidic water?

• They evaluate fluctuations that may affect large equipment corrosion.
• They consider cumulative effects on pipes and machinery beyond household plumbing.
• They assess treatment capacity relative to high-volume water use and process demands.

Seasonal and Multi-Year Variation in pH Levels

What does government data show about pH range and trends in Berkeley County?

• Samples collected from 2011 to 2018 in 7 wells show pH values from 6.1 to 8.7 standard units.
• The median pH is 7.95, generally within the EPA secondary standard range of 6.5 to 8.5.
• One of 16 samples fell below 6.5, indicating occasional acidic conditions in the groundwater.

Matching Treatment Capacity to Daily Water Demand

How can households determine if a treatment system meets their water use?

• Estimate daily water consumption in gallons per day based on household size and usage habits.
• Consider peak usage times when demand may temporarily increase.
• Choose a water treatment system with capacity exceeding average daily use for effective pH adjustment.

Household Symptoms That Indicate Acidic Water

What signs commonly suggest acidic water in home plumbing?

• Visible blue-green staining on fixtures from copper pipe corrosion.
• Metallic taste in tap water, though tastes vary by sensitivity.
• Premature deterioration or pitting on faucets and valves.

What symptoms do not necessarily indicate acidic water?

• Cloudiness or sediment—these relate to other water quality factors.
• Strong odors or discoloration often come from different sources.

Understanding Certified Laboratory pH Test Results

What information does a lab report provide about water acidity?

• It gives precise pH values with units reflecting acidity or alkalinity.
• Reports include sample date and method used, ensuring traceability.
• Interpretation compares results to the EPA secondary standard range of 6.5 to 8.5 but notes this is an aesthetic guideline, not a health threshold.

Changes After Using a Fleck Acidic / Low-pH Water Filter

Once a Fleck System is configured to treat water acidity and meets the household’s measured daily demand, noticeable improvements occur. Water pH levels stabilize closer to neutral, reducing metal corrosion effects and protecting fixtures. Water tastes and clarity may improve as water chemistry balances.

Addressing acidic water in Berkeley County homes begins with understanding local groundwater pH variation and confirming household water conditions through certified testing. The Fleck Acidic / Low-pH Water Filter ships ready to configure, providing targeted capacity for residential needs to help manage pH-related water concerns effectively.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2018-08-30. 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 pH in the 120FLRD aquifer (Berkeley County): 16 results from 7 wells, median 7.95 standard units, range 6.1-8.7 standard units; EPA secondary standard for pH is 6.5-8.5 (aesthetic/corrosivity, not health-based); 1 of 16 sampled results fell below 6.5
