Legacy Soil Pollution: Higher lead levels may lie just below surface

A study of data from hundreds of soil samples taken around six old water tower sites in southern Rhode Island finds that even when lead levels on the surface are low, concentrations can sometimes be greater at depths down to a foot. The findings inform efforts to assess the effect of lead paint from old water towers on surrounding properties.

PROVIDENCE, R.I. [Brown University] — A newly published analysis of data from hundreds of soil samples from 31 properties around southern Rhode Island finds that the lead concentration in soil at the surface is not always a reliable indicator of the contamination a foot deeper. The study, led by Brown University Superfund Research Program researchers at the request of the Rhode Island Department of Health (RIDOH), informs ongoing efforts to assess the impact of the state’s legacy of lead-painted water towers.

Women 16–49 at Risk of Multiple Pollutants

In a new analysis of thousands of U.S. women of childbearing age, Brown University researchers found that most exceeded the median blood level for two or more of three environmental pollutants that could harm brain development of fetuses and babies: lead, mercury, and polychlorinated biphenyls (PCBs).

PROVIDENCE, R.I. [Brown University] — Nearly 23 percent of American women of childbearing age met or exceeded the median blood levels for all three environmental chemical pollutants — lead, mercury, and PCBs — tracked in an analysis of data on thousands of women by Brown University researchers. All but 17.3 percent of the women aged 16 to 49 were at or above the median blood level for one or more of these chemicals, which are passed to fetuses through the placenta and to babies through breast milk.
