If your home's plumbing includes older pipes or fixtures, how does this impact lead levels?

Although Newark Water Department's public water system sampling on December 31, 2024, showed a lead 90th percentile concentration of 0.001 mg/L, this measurement reflects lead found in water as it runs through plumbing, not the source water itself. Lead presence typically arises from household plumbing components like lead pipes, solder, or brass fixtures, especially in older homes. This means that even if the source water is treated and monitored, lead can enter water between the treatment plant and your tap due to your internal plumbing materials and their condition.

If you observe year-to-year or seasonal changes in lead measurements, what does Newark's data show?

The Newark Water Department’s lead data is captured annually, with the latest from the end of 2024. This snapshot provides a regulatory compliance perspective but does not capture daily or seasonal fluctuations in lead concentrations at individual homes. Variability in household water use patterns, changes in water chemistry throughout the year, or disturbances in plumbing can cause lead levels to vary. Since sampling is periodic, homeowners should understand that your home's lead level might not match the municipal data at all times.

If you wonder how lead enters the water system in New Castle County, what does the information say?

Newark's water is drawn from surface water sources and undergoes multiple treatment processes (indicated by treatment codes 141, 240, and others). The source water itself is not the lead origin; lead contamination in water generally occurs downstream when water contacts lead-containing plumbing materials in the distribution system or at individual connections. The public system record confirms lead is not detected at hazardous levels system-wide, but lead leaching in private plumbing remains the main exposure route in the area.

If you want to rule out potential lead issues cost-effectively, what steps should you take before testing?

• Identify the age and type of your home's plumbing materials, particularly looking for lead pipes or old solder.
• Flush cold water taps for several minutes to reduce lead concentration before use, as water stagnant in pipes can accumulate lead.
• Use only cold water for cooking and drinking since hot water dissolves lead faster.
• Consider requesting a certified laboratory test on your tap water to know your home's specific lead level.

If you plan to reduce lead in your home's drinking water, how does the C-Series Lead in Water Filter help?

The C-Series System is a filtration technology designed to specifically target and reduce lead content from the point of use. Shipped ready to configure, it provides a reliable barrier against lead particulates and dissolved lead forms that may be present after water leaves the municipal system and passes through household plumbing. Because it addresses lead removal at the tap, it supplements municipal treatment and distribution controls, helping ensure safer water for drinking and cooking.

If you are preparing to ask for treatment information or a quote, what details should you have ready?

• Results from any recent water testing for lead and other metals in your home
• Details about your plumbing system materials (e.g., presence of lead pipe, solder, brass fixtures)
• Information on your household’s water usage patterns and any known water quality changes over time
• Notes on any previous water treatment equipment and its performance issues

Remember: Newark’s area water system lead data does not establish your home's individual water lead concentration. A detection at the system level is not a safety violation, and values below regulatory thresholds indicate compliance, not absence of lead exposure risk in household plumbing. Testing your home’s water is the only way to determine your specific condition.
