Drinking water can become contaminated with lead when there is corrosion in leaded plumbing. Because corrosion control was not used at the FWS water treatment plant, the levels of lead in Flint tap water increased over time. The proportion of elevated BLLs was ificantly higher 5. After the switch back to DWA, the percentage of elevated BLLs returned to levels comparable to those found before the water source switch. Flint residents have been recently advised by the U. Regular household tap water can be used for bathing and showering; however, young children should be prevented from drinking bath water.

Case management should be provided to all children with elevated BLLs. Adverse health effects are associated with lead exposure 1. On January 2,a water advisory was issued because of detection of high levels of trihalomethanes, byproducts of disinfectants.

On October 16,the Flint water source was switched back to DWA, and residents were instructed to use filtered tap water for cooking and drinking. Although unrelated to lead in the water, the water advisory likely reduced tap water consumption and increased consumption of bottled water.

Blood lead testing in Michigan is targeted to children living at or below the poverty level as well as to children enrolled in Medicaid. Analyses of BLLs obtained during four periods were conducted. Michigan blood lead surveillance data were reviewed, cleaned and de-duplicated, and each tested child was ased a unique identifier based on name, sex, date of birth and physical address. Based on the date of the blood test, were ased to one of the four periods.

If had multiple BLL tests during a single period, the single highest result was used, with venous blood tests preferred Free online sex in Flint capillary tests. Analyses were limited to tests on children living in residences in the FWS service area; children living in areas serviced by an alternative water system were not included.

Ninety-six percent of all test result addresses were geocoded. Age was defined as age at the time of the test. Children were excluded once they reached age 6 years. The two race examined were black or African American and white, the most frequently recorded races. The analysis was configured to for the possibility that some children might have had multiple BLL tests over the four periods. Multivariable regression analyses were conducted for the combined analysis period to adjust for possible confounding variables by age group, sex, race, and season.

Among these children, 7, received 9, blood lead tests before, during, and after the water source switch period. Among these tests, 2. During the period before the water source switch, among 2, blood lead tests, 3. In the United States, children with elevated BLLs typically have been exposed to lead through residential lead paint hazards often found in older homes or lead-contaminated house dust or soil 1. However, children and adults also can be exposed to lead through drinking water 4. Lead most commonly enters drinking water as a result of corrosion of leaded plumbing materials and is rarely found at the distribution point or wellhead 5.

There are three main factors that might influence the level of lead leeching into drinking water. These include 1 whether the plumbing included lead pipes, 2 the pH of finished water, and 3 the presence or absence of mineral scale in the plumbing 5. Lead in drinking water has been linked to elevated blood lead concentrations 6. Very young children consume more water per unit of body mass than do older children and adults, and they are more likely to engage in hand-to-mouth behaviors that put them at higher risk for exposure to lead in house dust and soil.

Additionally, BLLs in children tend to rise in warm weather months, a phenomenon that might be related to differential seasonal distribution of lead dust in houses as well as higher exposure to street dust associated with increased outdoor activity 8. The findings in this Free online sex in Flint are subject to at least five limitations.

First, spurious associations might have resulted from failure to control for all confounders because substantial information for certain covariates e. Thus, the impact of the high water lead levels for this age group might have been underestimated. There might be multiple sources of early childhood lead exposure 9 in areas with houses built before lead paint use in the United States was banned in However, this analysis suggests increased lead exposure related to consuming contaminated water in Flint.
