These abandoned mine sites often contain mine tailings, a type of processed ore that has had any valuable metals extracted and now has high concentrations of heavy metals. Heavy metals, like arsenic, have adverse impacts on the health of local wildlife, plants, and human populations. I (Spencer Harvey) am researching the phytoremediation potential of desert marigolds (<i><span style=\"font-weight: 400;\">Baileya multiradiata<\/span><\/i><span style=\"font-weight: 400;\">) to restore and reclaim mine sites contaminated\u00a0with arsenic. To accomplish this, the uptake of arsenic into the shoots and roots of the desert marigold is being measured to determine if the desert marigold is a viable plant to extract arsenic from the mine tailings. Additionally, the desert marigold and Arizona fescue (<\/span><i><span style=\"font-weight: 400;\">Festuca arizonica<\/span><\/i><span style=\"font-weight: 400;\">) are being looked at to control erosion and reduce the mobility of contaminated soil offsite. The success of\u00a0erosion control will be measured by growing vegetation in a flume containing mine tailings and subjecting the flume to simulated rain events.\u00a0 <\/span><\/p>\n<p><strong>Participants:<\/strong><br \/>\nDr. Bridget Bero, Associate Chair Civil and Environmental Engineering<br \/>\nDr. Terry Baxter, Professor Civil and Environmental Engineering<br \/>\nSpencer Harvey, graduate student NAU<br \/>\nJosue Juarez, graduate student NAU<br \/>\nKalani de Silva, undergraduate NAU<\/p>\n<p><strong>Funding:<\/strong> Bureau of Land Management (BLM) grant<\/p>\n<div class='shortcode-column-container'><!-- shortcode-column -->\n<div class=\"shortcode-column shortcode-column--count-2\">\n    \n<figure id=\"attachment_5162\" aria-describedby=\"caption-attachment-5162\" style=\"width: 300px\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-5162 size-portrait-image\" src=\"https:\/\/nau.edu\/wp-content\/uploads\/sites\/74\/Mine-Remediation_1-300x450.jpg\" alt=\"Mine Remediation project\" width=\"300\" height=\"450\" \/><figcaption id=\"caption-attachment-5162\" class=\"wp-caption-text\">Magma Copper Mine, Superior, AZ taken by Spencer Harvey<\/figcaption><\/figure>\n\n<\/div>\n\n<!-- shortcode-column -->\n<div class=\"shortcode-column shortcode-column--count-2\">\n    \n<figure id=\"attachment_5163\" aria-describedby=\"caption-attachment-5163\" style=\"width: 300px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-5163 size-portrait-image\" src=\"https:\/\/nau.edu\/wp-content\/uploads\/sites\/74\/Mine-Remediation_2-300x450.jpg\" alt=\"Mine Remediation project\" width=\"300\" height=\"450\" \/><figcaption id=\"caption-attachment-5163\" class=\"wp-caption-text\">Mine Tailings Flume in Research Greenhouse taken by Adair Patterson<\/figcaption><\/figure>\n\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Abandoned Mine Remediation in Northern Arizona Purpose:\u00a0This project is part of an ongoing assessment on the remediation of abandoned mine sites in northwestern Arizona.
