Starting with Home Water Quality Checks Before Laboratory Testing

This week, if you are determining whether perchlorate is affecting your household water in Hampton, start by ruling out simple sources and checks before considering laboratory analysis. First, review any recent notices from your local water provider, AQUARION WATER CO OF NH, which serves Hampton through groundwater sources. These notices often clarify recent testing results or water changes.

Next, visually and by taste, assess your water for any unusual changes, knowing that perchlorate itself is colorless and odorless. Since low-level detections are common and not safety violations, personal perception alone is insufficient.

Only after these steps should you consider a certified laboratory test specific to your home's water. This test remains the only way to confirm perchlorate levels for your well or tap.

Additional Considerations for Commercial or Industrial Operators

While households in Hampton focus on understanding perchlorate occurrence through area data and home testing, commercial or industrial users have extra factors to consider. These include regulatory compliance for discharge permits, potential impacts on manufacturing processes, and cumulative water use variations. Such users often require more frequent and detailed monitoring and may need treatment solutions tailored to operational scale.

Interpreting Certified Laboratory Reports on Perchlorate

A certified laboratory report for perchlorate will specify concentration amounts in micrograms per liter (µg/L), usually detecting values above a reporting level, such as 4.0 µg/L. For your area's system, sampling from 2001 to 2005 found no detections above this level.

The report will include information on detection status (whether perchlorate was detected or below the reporting level), the units measured, and sometimes a comparison to federal or health advisory guidance. Understanding these elements helps you make informed choices without mistaking a low-level detection for a health violation.

The Meaning of 'Detected,' 'Median,' and 'Range' in Area Sampling Records

In the AQUARION WATER CO OF NH sampling record covering Hampton, perchlorate was tested 18 times, with all results below the 4.0 µg/L reporting level. 'Detected' means the measuring instrument found perchlorate at or above this threshold; here, none was detected.

'Median' refers to the middle value in a distribution of detected levels, which in this case is not applicable due to no detections. 'Range' indicates the lowest and highest measured values; for perchlorate here, it is below detection limits throughout sampling. These terms help describe population-level data but do not represent individual household water quality.

Impact of Sampling Conditions and Source Type on Expected Perchlorate Levels

Sampling depth, well depth, and groundwater source characteristics influence perchlorate presence. Since AQUARION WATER CO OF NH uses groundwater supply, variability can occur from aquifer geology and recharge patterns.

Deeper wells may draw water less exposed to surface contaminants, whereas shallow wells can reflect nearer-surface influences. Knowing your water source and well depth assists in interpreting test results and deciding on treatment needs.

What Hampton Residents Should Not Conclude from Public Water Data

Importantly, residents should not assume that absence of perchlorate detection in the public water system data guarantees their home water lacks perchlorate. Conversely, detecting low perchlorate levels does not imply a violation or unsafe condition. Each household’s water quality depends on private plumbing and well conditions that these records do not represent.

To address perchlorate concern specifically, equipment such as the Pentair Perchlorate Filter ships ready to configure for home use. It offers a documented approach to reduce perchlorate if your testing indicates a need. However, testing remains a necessary first step rather than relying solely on area-level data.

Where this information comes from

Source: EPA SDWIS public water system record. Sampled 2002-12-12. These figures describe the public water system's record, not the plumbing inside any individual building.

On record: EPA UCMR1 monitoring (2001-2005) for AQUARION WATER CO OF NH (NH1051010), NH: 18 results across 1 listed contaminants, 0 detections above the reporting level; nothing detected above the method reporting level
