Range Resources Voluntary Plan to Close Yeager Wastewater Impoundment in SWPAMarcellus Drilling News
A voluntary plan created and submitted by Range Resources to the Pennsylvania Dept. of Environmental Protection to permanently close (and restore) the Yeager wastewater impoundment (i.e. open pond) site in Amwell Township, located in Washington County, PA. The plan was tweaked by the DEP to require Range to test for certain compounds underneath the two liners in the impoundment--liners that, according to Range, had holes in both layers.

The complex geologic setting and historical mining of the anthracite mines creates a challenge to calculate the volume of water stored within the underground mines. EPCAMR’s recent mapping effort has reasonably found that almost 9 billion gallons of mine water resides in storage in 10 mines in the Southern Field and approximately 435 billion gallons in all the Northern Field. This associated report attempts to build on previous investigations to locate and quantify large volumes of water existing in underground mine voids, known as Mine Pools, in the Southern and Northern Anthracite Coal Fields of Eastern Pennsylvania. The goal of this project was to produce 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. When pairing treatment with the ability to control the amount of water coming out of the mines, large flushes of stormwater that would normally escape untreated could be retained, later treated and released in times of low water or drought conditions.

How to Overcome Public Perception Issues on Potable Reuse Projects
Michael R. Markus, P.E., Orange County Water District, Fountain Valley, CA
Eleanor Torres, Orange County Water District, Fountain Valley, CA
Abstract
The purpose of this paper is to provide an overview of how the Orange County Water District
(the District; OCWD) was able to insulate itself from public opposition to its potable reuse
project, the Groundwater Replenishment System (GWRS).
To understand what challenges the District would be facing it is important to first understand
what was happening with other projects that were being developed at the same time in
Southern California. Second, it is important to understand the process by which the outreach
program was developed and how it was executed. That program was ongoing and changed
with the project to help anticipate and react to various issues that developed. Finally, it will be
shown how important it is to continue the outreach efforts and outline the various steps the
District has taken to educate people on the benefits of reuse.
Introduction
The Orange County Water District manages a very large groundwater basin (basin) in central
and north Orange County in the state of California, U.S.A. It was created by the State
Legislature in 1933 for that purpose and is governed by a 10-member Board of Directors that
sets policy, establishes the amount of pumping out of the basin and sets tariffs. The District
currently has set the amount of groundwater that can be pumped out of the basin at 77% of the
total water demands for its 19 retail agencies which serve 2.5 million people. The remaining
23% of its water supply is dependent on water that is imported into the region.
The Southern California region has a semi-arid climate, which receives approximately 355 mm
of rainfall per year. Most of its water is imported from two primary outside sources, the
Colorado River and the Sacramento-San Joaquin Delta (the Delta) in Northern California. The
Metropolitan Water District of Southern California (MWD) built a 320 km aqueduct in the
1930’s bringing water from the Colorado River into Southern California and then participated in
the building of a 640 km aqueduct in the 1960’s from Northern California to bring water from
the Delta to Southern California. These supplies are enough to meet the water demands in
most years, but they are variable and the amount of water through these systems is dependent
on hydrology and certainly in the future, climate change.
Groundwater basins provide an important source of supplemental supply to the imported water
provided by MWD. A sustainably managed basin can provide a reliable source of low-cost
water, with groundwater costing half as much as imported water. The Orange County Water
District relies on rainfall, stormwater capture, Santa Ana River flows, untreated imported water
and recycled water for refilling its basin. This amount of water.
