<br /> Sensitive Receptor Survey
<br /> A Sensitive Receptor Survey (SRS)was conducted in 2001 by Advance Geoenvironmental. A
<br /> records search at the Department of Water Resources and an on-the-ground survey in the area
<br /> identified four water supply wells within a 2,000 foot radius of the Site. City of Lathrup Well # 7 C
<br /> lies 1,800 feet southeast of the site. Drinking water at and near the Site is currently supplied by
<br /> the City of Lathrup.
