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.
