Notes:<br />
* Cancer risk reflects the arsenic groundwater pathway only and does not include other human health mortality or morbidity risks from non-carcinogens, nor do they<br />
reflect ecological and socio-economic damages that could occur. Thus, the benefits are underestimated in this RIA.<br />
** Cancer risks avoided are based on National Academy of Science (2001) data, which represents recent scientific in<strong>for</strong>mation.<br />
