PEWAUKEE - A warning for people living in the Village of Pewaukee: their water could have high levels of lead in it. The village tests for lead every three years and for the first time ever, the water in some of the homes tested positive for a level higher than what's allowed. If you live in a home built before 1985 in downtown Pewaukee, the village wants you to run the water for at least 30 seconds before drinking it, or using it for cooking, but the Department of Public Works says that's only necessary if the water hasn't been used for 6 to 8 hours: the time it takes for lead to build up. "It needs to stand for an extended period of time before the lead will dissolve in the water, so if you use the water periodically throughout the day, use it an hour here and an hour later there really isn't an issue,” David White from the Department of Public Works said. The lead comes from the plumbing in older homes, plumbing that was outlawed in 1984. Steven Gottfried lives in a home built in 1930. He has two little kids, and says he isn't taking any chances. Instead of running his water for 30 seconds, he plans to avoid it all together. "We’re very concerned because we have children, and we do have a filter in our fridge, and we'll depend on that. It's more the unknown, and not knowing what the true implications are,” Gottfried said. The DPW says the warning will last a minimum of six months, while they do more tests. DPW does not know why the levels are higher now, but say it's not related the flooding the village experienced in spring.
