<br />Executive Summary
<br />On September 1,5, 20102, IEA conducted a visual inspection and fungal, saimpling at Roseville Fire Station
<br />No. 1. Fungal growth had occurred, in the, basement due to repeated flooding reportedly caused, by water
<br />infiltration through the basement wialls. Roof leaks had also occurred. A surnmary of fig.

<br />1. Visible fungal growth in the basel,ment was found at the base of'sheetrock walls in several, areas
<br />and, on equipment" stored in the Fire Department, Equipment Room. Numerous wateT-stam-ed
<br />ceiling tiles, were observed in the older portion of the building.

<br />levels of' ftmgi associated with interior sources of fimga,l contarnination were found in samples
<br />collccted ftorn, ground level areas. Fungal, contamination 'in the basement is, likely, th,ei source, of'
<br />the airborne ftirigal contamination.
