Lead Concerns in Essex County Water: Understanding the Situation in Beverly

This week, your household faces the decision of how to clarify the nature and impact of lead in your drinking water supply.

How Lead Enters Water in Beverly's Public System

Lead as a Plumbing Contaminant, Not Source

In Beverly, Essex County, water comes from surface sources treated by the Salem and Beverly Water Supply Board. EPA data shows no health-based violations, indicating the water at entry meets federal standards. Lead measurements relate to the 90th percentile in the distribution system, reflecting plumbing influences rather than source water contamination.

Lead's Origin in Household Plumbing

Lead can leach into water due to materials and corrosion in household pipes, fixtures, or solder. This occurs regardless of source water quality or treatment processes applied by the public utility. The EPA 90th percentile lead level of 0.0017 mg/L for December 2025 samples describes typical distribution results and does not define any single home’s water.

Additional Considerations for Commercial or Industrial Operators

Volume and Regulatory Parameters

Commercial or industrial users may need to evaluate lead in larger volumes and meet specific regulatory frameworks beyond residential needs. They require data on potential peak lead concentrations and corrosion control tailored to complex plumbing networks.

Impact on Process Equipment

Facilities must consider lead interaction with process water, including possible accumulation or interference in sensitive equipment. This extends beyond drinking water considerations to operational integrity.

Influence of Sampling Depth and Water Source Type

Sample Depth Reflects Distribution, Not Source

Lead sampling in the Salem and Beverly system focuses on water after treatment and distribution, capturing effects from pipes and household plumbing rather than raw source characteristics. This distinction governs interpretation for individual consumers.

Surface Water as Source

Beverly's water supply derives from surface water sources, which undergo multiple treatment processes. These treatments reduce many contaminants but do not eliminate lead introduced through in-home plumbing materials.

Changes at the Tap with the Documented Treatment Technology

Reduction of Lead Concentration

The Pentair Lead in Water Filter system ships ready to configure for residential use, designed to reduce lead and improve water quality at the tap by capturing lead particles and ions before consumption.

Consistency of Treated Water Quality

This filter provides a measurable improvement in lead levels at outlets, independent of fluctuations in distribution or plumbing conditions, adding a layer of protection where household pipes may contribute lead.

Fixtures and Appliances Most Affected by Lead Presence

Drinking and Cooking Outlets

Faucets used for drinking and cooking are the most critical points where lead exposure risk occurs, as these directly supply water for ingestion.

Ice Makers and Water Dispensers

Appliances that incorporate home water lines, such as ice makers and refrigerators with water dispensers, are also key fixtures impacted by lead in plumbing.

Final Step: Confirming Your Household’s Water Lead Level

The essential test to clarify your household situation is a certified laboratory measurement of lead concentration from your tap. A result below the EPA action level would confirm the water's relative safety for consumption and help determine the need for additional treatment like the Pentair Lead in Water Filter.
