Arsenic in Camden County: Understanding Area Measurements and Treatment Options for Homeowners

What the Measured Range Means Against Federal Standards—and What It Does Not Mean

In Camden County, New Jersey, groundwater samples taken from aquifer 211MRPAL between 2011 and 2025 show arsenic levels ranging from 0.12 to 3.2 micrograms per liter (µg/L), with a median of 1.3 µg/L. These results come from 46 samples across 18 wells, none of which exceeded the federal arsenic standard of 10 µg/L. This federal threshold is a health-based limit, setting the maximum allowable contaminant level in drinking water to protect public health.

It is important to understand what these area-based measurements mean—and what they do not mean for your home. The detection of arsenic in regional wells indicates the presence of arsenic in the aquifer but does not specify the concentration in your own well water. Neither a detection nor values below the regulatory limit constitute a violation or prove any health risk. Testing your home water is the only way to know your exact arsenic concentration.

A Worked Example: Reading the Record’s Median and Range as a Homeowner Would

Imagine your household water is drawn from a well tapping this same aquifer. The median value of 1.3 µg/L suggests that, in the sampled area, half of the measurements were above this level and half below. The full range from 0.12 to 3.2 µg/L shows some variability among wells, influenced by natural geologic factors.

This means your water could fall anywhere within that range or possibly outside it. Without a specific test of your water, these area-wide numbers serve only as a general backdrop rather than a definitive assessment. Knowing this range helps you understand potential arsenic levels, but your household’s actual concentration remains uncertain until tested.

How Public-System Records Differ from Private-Well Testing in What They Establish

Public water systems are regularly monitored and must comply with federal standards. Their records reflect aggregated data from many locations and treatment stages and are documented publicly. In contrast, private wells are the sole responsibility of homeowners and are not covered by these monitoring programs.

Government sampling in Camden County’s aquifer area provides valuable information about groundwater quality on a broad scale but cannot replace testing your well water specifically. Unlike public systems, private wells vary widely due to well construction, depth, and local geology. Therefore, testing your water at a certified laboratory is the only way to confirm if arsenic is present and at what level in your household water.

The Role of Plumbing Material and Age, Separate from the Source Water

Arsenic levels measured at the source do not change due to household plumbing materials or their age because arsenic is naturally occurring in groundwater. However, plumbing can affect other water characteristics unrelated to arsenic.

It is important to keep in mind that even if your water source has low arsenic levels, older plumbing materials might influence water quality in ways not linked to arsenic. Conversely, arsenic treatment focuses strictly on removing arsenic from the water before it reaches your taps, independently from plumbing concerns.

How the Documented Treatment Technology Removes or Neutralizes the Constituent

For households weighing treatment options for arsenic, the C-Series Arsenic Filter is a documented technology designed specifically to reduce arsenic concentrations effectively. This system uses a filtration process that attracts and retains arsenic particles, lowering their levels in household water to meet health-based standards.

The C-Series System ships ready to configure for your water supply and addresses arsenic regardless of its initial concentration measured in your well. While the government data helps you understand possible arsenic presence, this technology provides a practical and focused solution once you know your household arsenic level from testing.

How Sample Depth, Well Depth, or Source Type Changes What a Reader Should Expect

The area’s groundwater samples came from wells ranging in depth from 118 to 1,505 feet. Arsenic concentration can vary with depth, as geological formations differ at various layers. Deeper wells may encounter different mineral content, potentially altering arsenic levels compared to shallower ones.

Similarly, the type of water source—whether a private well drawing from a particular aquifer horizon or a public system combining multiple sources—affects arsenic presence. Understanding well depth and source type helps anticipate variations, yet the only way to determine your home's specific arsenic level is through individual testing.

For households in Camden County concerned about arsenic, the C-Series Arsenic Filter offers a targeted treatment solution designed to reduce arsenic after you confirm your water’s concentration. Armed with a certified laboratory’s test results, the C-Series System can be selected to meet your household’s specific needs, ensuring arsenic levels are addressed effectively and reliably.
