A Clearfield County native, Lefever grew up volunteering with her father on various environmental projects.<\/p>\n<p>\u201cFrom basically the time I was six years old, I started doing this work as a volunteer. Whether it was just going out and walking along and watching, or helping to move some little rocks, it just helped me to really appreciate and love the outdoors. And as a result of that, I knew that I didn\u2019t want to sit behind a desk all day, every day,\u201d states Lefever.<\/p>\n<p>According to Lefever, since starting her job at the Elk County Conservation District, she hasn\u2019t had a boring day. She explains, \u201cSome days I\u2019m behind a desk writing grants or sorting through water quality data. Other days I\u2019m out sampling water or doing construction projects like stream habitat improvements.\u201d<\/p>\n<p>Monitoring and restoration efforts in the county are community-driven, meaning that Lefever\u2019s days are spent answering calls from locals reporting issues in nearby rivers and streams, then going out to the area to assess the problem and come up with a solution.<\/p>\n<p>An example of this is a more recent project on Dents Run, a tributary of the Bennett Branch, which carries a large amount of acid mine drainage into the creek.<\/p>\n<div id=\"attachment_40179\" style=\"width: 950px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-40179\" class=\"size-full wp-image-40179\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2025\/08\/Lefever_P8060019_ForWeb.jpg\" alt=\"Dents Run.\" width=\"940\" height=\"705\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2025\/08\/Lefever_P8060019_ForWeb.jpg 940w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2025\/08\/Lefever_P8060019_ForWeb-300x225.jpg 300w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2025\/08\/Lefever_P8060019_ForWeb-600x450.jpg 600w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2025\/08\/Lefever_P8060019_ForWeb-768x576.jpg 768w\" sizes=\"auto, (max-width: 940px) 100vw, 940px\" \/><p id=\"caption-attachment-40179\" class=\"wp-caption-text\"><span style=\"color: #808080;\">Dents Run. (Credit: Jake Pistner \/ Elk County Conservation District)<\/span><\/p><\/div>\n<h3><span style=\"color: #808080;\">Continuous Water Quality Monitoring on Dents Run<\/span><\/h3>\n<p>Drainage from nearby coal mines has led to the creation of sulfuric acid, which dissolves metals like iron and aluminum in rocks, flooding Dents Run\u2014and its tributaries\u2014with acid and heavy metals. These contaminants impact aquatic species\u2019 health and water quality conditions.<\/p>\n<p>There are currently about 15 different treatment systems in Elk County, both passive and active, that need to be maintained. In order to ensure that these systems are functioning properly, Lefever uses <a href=\"https:\/\/www.fondriest.com\/ysi-exo1-multi-parameter-water-quality-sonde.htm\" target=\"_blank\" rel=\"noopener\">YSI EXO1<\/a> sondes to measure water quality near treatment sites to evaluate if they are effectively mitigating acid mine drainage.<\/p>\n<p>Lefever has three sondes that she moves around the watershed over the course of the year, with the exception of winter due to ice conditions. The rest of the year, monitoring Dents Run presents some unique challenges due to the high variances in flow the waterway experiences.<\/p>\n<p>These variances can result in the sonde being totally submerged as a result of heavy rainfall or left in the air due to the water level dropping.<\/p>\n<p>Aside from risks to the equipment, variable flows can also impact measurements. Low flow conditions result in high concentrations of acid and metal entering the waterway. In contrast, high flow conditions can severely dilute concentrations, making it harder to notice acid mine drainage.<\/p>\n<div id=\"attachment_40174\" style=\"width: 950px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-40174\" class=\"size-full wp-image-40174\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2025\/08\/Lefever_P8060008_ForWeb.jpg\" alt=\"Elk County Conservation District Watershed Technician, Micaela, is removing one of the sondes from it\u2019s protective housing to clean it, calibrate it, and download the data.\" width=\"940\" height=\"705\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2025\/08\/Lefever_P8060008_ForWeb.jpg 940w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2025\/08\/Lefever_P8060008_ForWeb-300x225.jpg 300w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2025\/08\/Lefever_P8060008_ForWeb-600x450.jpg 600w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2025\/08\/Lefever_P8060008_ForWeb-768x576.jpg 768w\" sizes=\"auto, (max-width: 940px) 100vw, 940px\" \/><p id=\"caption-attachment-40174\" class=\"wp-caption-text\"><span style=\"color: #808080;\">Elk County Conservation District Watershed Technician, Micaela, is removing one of the sondes from it\u2019s protective housing to clean it, calibrate it, and download the data. (Credit: Jake Pistner \/ Elk County Conservation District)<\/span><\/p><\/div>\n<p>To combat this, the sondes measure pH and conductivity continuously for a few months before they are moved to a new site in the watershed in order to capture conditions under different flow conditions. Data is reviewed on a monthly basis.<\/p>\n<p>Low pH indicates that the water is acidic and that the treatment strategy may need to be replaced or maintained. Similarly, high conductivity may indicate the presence of heavy metals, which also points to assessing the treatment system upstream.<\/p>\n<p>Depending on the sonde measurements, Lefever will conduct spot sampling using individual sensors elsewhere in the tributary as well as grab samples for lab analysis so that the team can create targeted solutions to the specific problem.<\/p>\n<p>Lefever also monitors areas that have been largely unimpacted by acid mine drainage to ensure that these areas remain healthy and that discharge hasn\u2019t popped up.<\/p>\n<p>In cases where issues are detected and a treatment system will be added or improved, the sondes usually remain deployed for a longer period in order to evaluate any changes after intervention.<\/p>\n<div id=\"attachment_40177\" style=\"width: 950px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-40177\" class=\"size-full wp-image-40177\" src=\"https:\/\/www.fondriest.com\/news\/wp-content\/uploads\/2025\/08\/Lefever_P8060013_ForWeb.jpg\" alt=\"Elk County Conservation District Watershed Technician, Micaela, is calibrating the sonde using pH 4.0 buffer solution.\" width=\"940\" height=\"705\" srcset=\"https:\/\/news.fondriest.com\/wp-content\/uploads\/2025\/08\/Lefever_P8060013_ForWeb.jpg 940w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2025\/08\/Lefever_P8060013_ForWeb-300x225.jpg 300w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2025\/08\/Lefever_P8060013_ForWeb-600x450.jpg 600w, https:\/\/news.fondriest.com\/wp-content\/uploads\/2025\/08\/Lefever_P8060013_ForWeb-768x576.jpg 768w\" sizes=\"auto, (max-width: 940px) 100vw, 940px\" \/><p id=\"caption-attachment-40177\" class=\"wp-caption-text\"><span style=\"color: #808080;\">Elk County Conservation District Watershed Technician, Micaela, is calibrating the sonde using pH 4.0 buffer solution.
