Every three years, the Village conducts testing of the tap water in the homes for lead and copper. Per the Michigan Department of Environmental Quality (MDEQ), samples are collected from homes that are likely to have lead-containing solder or older copper plumbing. The Village does not have any known lead pipes in the system or any homes known to have lead service lines.
This July, we collected samples from 10 homes. The Action Level for lead, 15 parts per billion (ppb), is not a health-based standard but a level that triggers additional investigative sampling of water quality and requires educational outreach to customers. The MDEQ assesses compliance with the Action Level based on the 90th percentile of all lead and copper results collected in each round of sampling. The lead 90th percentile for the Village’s water supply is 24 ppb, which exceeds the Action level of 15 ppb. Test results showed two samples were over the Action Level for lead.
Even though only two locations of the 10 locations sampled were over 15 ppb, the Village water system would like to share some ways you can reduce your potential exposure to lead in your water or in the environment since lead can cause serious health problems if too much enters your body from drinking water and other sources. The most important things you can do is let the water run for 30 seconds to 2 minutes, per the EPA recommendations, or until it becomes cold. Use cold water tap for drinking, cooking, or preparing baby formula. Boiling your water will not reduce the amount of lead in water.
Over the next year, the Village will conduct additional monitoring of the water system and, working with MDEQ, will determine if corrosion control measures are necessary to reduce corrosion in household plumbing. At this time, we believe subsequent rounds of sampling will show the water system results to be below the Action Level. Additional information regarding the lead in water can be found on the Village’s website: www.lawrencemi.org or at the MDEQ web page at www.michigan.gov/deqleadpublicadvisory.
