Lead contamination in drinking water: exposure and remediation - Solution

Exposure Assessment And Testing

We help identify and quantify lead exposure risks by providing guidance on water testing protocols and interpreting results to determine contamination sources and levels.

  • Recommend certified laboratory testing for accurate lead concentration measurement.
  • Guide on proper sampling techniques, including first-draw and flushed samples.
  • Assist in interpreting test results against regulatory standards like the EPA Action Level.
  • Help identify potential sources, such as lead service lines, plumbing fixtures, or solder.

Immediate Exposure Mitigation

We provide actionable steps to immediately reduce lead exposure from drinking water while long-term solutions are implemented.

  • Recommend flushing pipes before use, especially after long periods of stagnation.
  • Advise using only cold water for drinking and cooking, as hot water leaches more lead.
  • Suggest point-of-use certified lead removal filters for taps used for consumption.
  • Guide on identifying and avoiding specific fixtures or faucets with higher lead risk.

Long-Term Remediation And System Replacement

We support planning and implementing permanent solutions to eliminate lead sources from the water distribution system.

  • Provide information on full or partial lead service line replacement programs and procedures.
  • Advise on corrosion control treatment adjustments to minimize lead leaching from plumbing.
  • Guide selection and installation of certified point-of-entry filtration or treatment systems.
  • Offer resources on financing, incentives, and regulatory compliance for remediation projects.

Public Education And Community Outreach

We assist in developing and disseminating clear information to raise awareness and promote protective behaviors regarding lead in water.

  • Help create educational materials on lead exposure health effects, especially for vulnerable populations.
  • Support the design of public communication plans for test results and remediation updates.
  • Provide templates for homeowner guidance on testing, filters, and plumbing inspections.
  • Facilitate connections to public health agencies and technical assistance programs.

Frequently Asked Questions (Q&A)

A: Lead typically enters drinking water through corrosion of plumbing materials containing lead, such as lead pipes, lead solder, or brass fixtures in homes built before 1986. The risk is highest when water sits stagnant in these pipes for several hours, allowing lead to leach in. Homes with lead service lines or internal plumbing are most at risk, and there is no safe level of lead exposure.

A: Lead exposure is particularly dangerous for children, as it can cause irreversible damage to the developing brain and nervous system, leading to learning disabilities, behavioral problems, and lower IQ. In adults, it can contribute to cardiovascular issues, decreased kidney function, and reproductive problems. Because these effects occur even at low levels, immediate action is recommended if lead is detected.

A: The most effective long-term solution is to replace any lead pipes, solder, or fixtures. For immediate remediation, use a certified water filter labeled to remove lead (NSF/ANSI Standard 53 or 58). Always use cold water for drinking and cooking, as hot water leaches more lead, and flush your pipes by running the tap for several minutes after water has been sitting for six hours or more.
