The monitoring site is an abandoned underground and surface coal mine operation called the West End Colliery.&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.solinst.com\/onthelevel-news\/wp-content\/uploads\/2022\/11\/outflow.png\"><img loading=\"lazy\" decoding=\"async\" width=\"432\" height=\"587\" src=\"https:\/\/www.solinst.com\/onthelevel-news\/wp-content\/uploads\/2022\/11\/outflow.png\" alt=\"treated abandoned mine drainage\" class=\"wp-image-3958\" title=\"Treated Abandoned Mine Drainage\" srcset=\"https:\/\/www.solinst.com\/onthelevel-news\/wp-content\/uploads\/2022\/11\/outflow.png 432w, https:\/\/www.solinst.com\/onthelevel-news\/wp-content\/uploads\/2022\/11\/outflow-221x300.png 221w\" sizes=\"auto, (max-width: 432px) 100vw, 432px\" \/><\/a><figcaption><em>Mocanaqua tunnel discharge and treated wastewater outfall to the Susquehanna River<\/em><\/figcaption><\/figure>\n\n\n\n<p>An on-site stream flows underground into the former coal mines and comes out as polluted mine drainage discharge. &nbsp;The acidic 3.7 pH water carries a concentration of 4 milligrams per litre of each heavy metal, iron and aluminium, which flows into the Susquehanna River at an average of 17 cubic feet per second.<\/p>\n\n\n\n<p>The polluted stream discharge gained interest from the <a href=\"https:\/\/www.srbc.net\/\" target=\"_blank\" rel=\"noreferrer noopener\">Susquehanna River Basin Commission<\/a> (SRBC). The SRBC regulates withdrawals on the river for consumptive use. Consumptive use (CU) is water that is used in a way that it cannot be returned to the environment without some form of degradation to its quality or quantity. For example, the SRBC looks to mitigate water consumed by cooling towers at power plants or used to frack gas wells.<\/p>\n\n\n\n<p>Projects or industries that cannot achieve their own mitigation or remediation of consumed water can pay a fee to provide make-up solutions on their behalf. That\u2019s where SRBC\u2019s interest in mine drainage comes into play.<\/p>\n\n\n\n<p>The SRBC investigates options that may offer mitigation or make-up water for consumptive users in the river basin. This includes evaluating flooded underground mine pools for potential water storage and treatment before it gets discharged.<\/p>\n\n\n\n<p>Controlling the amount of water being discharged from the mine pools, allows treatment, and then release when water levels are low. This provides clean water to the river basin that would have previously been left untreated. &nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Investigating Abandoned Mine Storage and Discharge<\/h3>\n\n\n\n<p>The water monitoring program stemmed from EPCAMRs 3D mine pooling mapping initiative: <a href=\"https:\/\/epcamr.org\/home\/current-initiatives\/technical-assistance\/watershed-assessment\/mine-pool-mapping-initiative\/\" target=\"_blank\" rel=\"noreferrer noopener\">3D Modeling of Eastern Pennsylvania Anthracite Mine Pools in Earthvision to Improve Water Quality Restoration and AMD Treatment Via Consumptive Use Mitigation Projects in the Susquehanna River Basin<\/a><\/p>\n\n\n\n<p>EPCAMR develops three-dimensional mine pool models to help estimate water storage volumes. Furthering this initiative, EPCAMR teamed up with SRBC for a field investigation. The water monitoring project was funded by a Consumptive Use Mitigation Grant that EPCAMR received from SRBC.<\/p>\n\n\n\n<p>Ten monitoring stations were set up to investigate surface water infiltration, flow, chemistry, and mine pool elevations in the Mocanaqua mine drainage rock tunnel and underground mine pool complexes.<\/p>\n\n\n\n<p>The program employs <a href=\"https:\/\/solinst.com\/products\/dataloggers-and-telemetry\/3001-levelogger-series\/levelogger\/\"><\/a><a href=\"https:\/\/solinst.com\/products\/dataloggers-and-telemetry\/3001-levelogger-series\/levelogger\/\" title=\"Solinst Water Level Dataloggers\" target=\"_blank\" rel=\"noreferrer noopener\">Solinst Levelogger water level dataloggers<\/a>.

Water level data is stored in Excel spreadsheets after it has been barometrically compensated using the Levelogger software.&nbsp; This allows the data to be used in calculations and graphs for reports.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Interpreting Water Monitoring Results<\/h3>\n\n\n\n<p>By interpreting the water level data, different levels of the mine pool below ground were found. Water level data were mapped to show how water moves across the site, down into the underground mines, and out of the tunnel.<\/p>\n\n\n\n<p>The findings provided insight into the ability to manipulate the flows to allow storage of the water during high flow and release it during low flow (like a dam). The data also aided in the creation of a 3D mine pool model where estimates could be made on the volumes of water held in the underground mines.<\/p>\n\n\n\n<p>In addition, the study helped evaluate the effectiveness and estimated costs of different types of mine drainage treatment (e.g., in-situ, passive and active treatment options). As the area was purchased by the state and added to the Pinchot State Forest Tract, the discharge comes from public land. The state would like the discharge to be remediated, along with other hazardous abandoned mine features, as hunters, hikers and rock climbers use this natural area.&nbsp;<\/p>\n\n\n\n<p>Overall, EPCAMR has been pleased with the use of Solinst Leveloggers, since introduced to them in 2018. &nbsp;EPCAMR find Leveloggers to be more cost-effective compared to other similar instruments on the market. Michael A. Hewitt, Program Manager at EPCAMR says \u201cwe have grown to like their reliability and function over the years.\u201d&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><a href=\"https:\/\/www.solinst.com\/onthelevel-news\/wp-content\/uploads\/2022\/11\/trusty-rusty.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.solinst.com\/onthelevel-news\/wp-content\/uploads\/2022\/11\/trusty-rusty.jpg\" alt=\"solinst levelogger affectionately called trusty rusty\" class=\"wp-image-3972\" width=\"720\" height=\"488\" title=\"Solinst Levelogger Affectionately Called Trusty Rusty\"\/><\/a><figcaption><em>Solinst Levelogger affectionately called \u201ctrusty rusty\u201d<\/em><\/figcaption><\/figure>\n\n\n\n<p>He continues \u201cone I call \u201ctrusty rusty\u201d in a stilling well at the polluted water discharge at the Mocanaqua Tunnel has functioned well and still produces data to this day since it was deployed in 2018 (4+ years in harsh conditions)\u201d. Michael notes that they do clean off the accumulated metals periodically but \u201cthat is a testament to its quality and longevity.\u201d&nbsp;<\/p>\n\n\n\n<p>Combined with their 3D modelling efforts, the field monitoring project and water level data provide a better picture of water flow through the abandoned mine site, its water storage capacity, and its potential to be treated and discharged as a clean water option for consumptive use mitigation.<\/p>\n\n\n\n<p>The study is contributing to EPCAMR\u2019s overall goal of reclaiming land impacted by past mining practices and getting it back to productive use. It will also help improve the water quality in the region, thereby allowing the areas to be enjoyed by future generations.<\/p>\n\n\n\n<p><em>Solinst thanks <\/em><em>Michael A.
