This concentration is below federal and,s_tate-action levels for soluble lead. The <br /> detected concentrations-are likely to be-naturally occurring; background concentrations. <br /> The laboratory data sheets-and chain of custody record are attached. <br /> We consider that the potential threat of soluable lead leaching to the groundwater <br /> :4 surface to be very low.
