Baseline Testing - The key developing a certified baseline includes the following:
a. Chain of Custody
b. Third Party - Unbiased Samples that are Experts in their field.
c. An understanding of the parameters that you need, based on your conditions.
d. An understanding of the results
Part I - Outreach Program - Baseline Testing (Ohio, Texas, New York, and Pennsylvania)
What is Chain of Custody?
This is a legal term that refers to the ability to guarantee the identification and integrity of samples from collection through reporting of test results. For the purpose of litigation, it is necessary to prove the legal integrity of all samples and data as part of the chain of evidence. Therefore, it is necessary to have and accurate written history for the sample. This history should include sample bottle preparation, bottle possession, handling, and location of samples and data from the time of collection through reporting. This can be conducted by using chain-of-custody procedures.
“Since there is no way to know in advance which samples and data may be involved in litigation, you should always follow chain-of-custody procedures whenever samples and data are collected, transferred, stored, analyzed, or destroyed.”
Samples and data are considered to be in your custody when:
1. they are in your physical possession;
2. they are in your view, after being in your physical possession;
3. they are in your physical possession and then locked up so that tampering cannot occur; and
4. they are kept in a secured area, with access restricted to authorized personnel only.
The six steps in a chain-of-custody process include:
Step 1. Sampling Preparations- determing test parameters based on YOUR need - not just a cookie cutter list.
Step 2. Sampling Operations- short term/ long term
Step 3. Sample Transport
Step 4. Receipt, Storage, and Transfer
Step 5. Sample Analysis
Step 6. Procedures for Data (Reporting/Storage/ Management)

Marcellus Shale - Using Mine Drainage and Acid Mine Drainage as a resourse and not a waste
The Abstract
"This report, prepared in cooperation with the Pennsylvania Department of Environmental Protection (PaDEP), the Eastern Pennsylvania Coalition for Abandoned Mine Reclamation, and the Dauphin County Conservation District, provides estimates of water budgets and groundwater volumes stored in abandoned underground mines in the Western Middle Anthracite Coalfield, which encompasses an area of 120 square miles in eastern Pennsylvania. The estimates are based on preliminary simulations using a groundwater-flow model and an associated geographic information system that integrates data on the mining features, hydrogeology, and streamflow in the study area. The Mahanoy and Shamokin Creek Basins were the focus of the study because these basins exhibit extensive hydrologic effects and water-quality degradation from the abandoned mines in their headwaters in the Western Middle Anthracite Coalfield. Proposed groundwater withdrawals from the flooded parts of the mines and stream-channel modifications in selected areas have the potential for altering the distribution of groundwater and the interaction between the groundwater and streams in the area.
Preliminary three-dimensional, steady-state simulations of groundwater flow by the use of MODFLOW are presented to summarize information on the exchange of groundwater among adjacent mines and to help guide the management of ongoing data collection, reclamation activities, and water-use planning. The conceptual model includes high-permeability mine voids that are connected vertically and horizontally within multicolliery units (MCUs). MCUs were identified on the basis of mine maps, locations of mine discharges, and groundwater levels in the mines measured by PaDEP. The locations and integrity of mine barriers were determined from mine maps and groundwater levels. The permeability of intact barriers is low, reflecting the hydraulic characteristics of unmined host rock and coal.
A steady-state model was calibrated to measured groundwater levels and stream base flow, the latter at many locations composed primarily of discharge from mines. Automatic parameter estimation used MODFLOW-2000 with manual adjustments to constrain parameter values to realistic ranges. The calibrated model supports the conceptual model of high-permeability MCUs separated by low-permeability barriers and streamflow losses and gains associated with mine infiltration and discharge. The simulated groundwater levels illustrate low groundwater gradients within an MCU and abrupt changes in water levels between MCUs. The preliminary model results indicate that the primary result of increased pumping from the mine would be reduced discharge from the mine to streams near the pumping wells. The intact barriers limit the spatial extent of mine dewatering. Considering the simulated groundwater levels, depth of mining, and assumed bulk porosity of 11 or 40 percent for the mined seams, the water volume in storage in the mines of the Western Middle Anthracite Coalfield was estimated to range from 60 to 220 billion gallons, respectively.
Details of the groundwater-level distribution and the rates of some mine discharges are not simulated well using the preliminary model. Use of the model results should be limited to evaluation of the conceptual model and its simulation using porous-media flow methods, overall water budgets for the Western Middle Anthracite Coalfield, and approximate storage volumes. Model results should not be considered accurate for detailed simulation of flow within a single MCU or individual flooded mine. Although improvements in the model calibration were possible by introducing spatial variability in permeability parameters and adjusting barrier properties, more detailed parameterizations have increased uncertainty because of the limited data set.
The preliminary identification of data needs includes continuous streamflow, mine discharge rate, and groundwater levels in the mines and adjacent areas. Data collected when the system is responding to hydrologic stresses such as recharge or pumping changes would provide information on hydraulic barrier integrity and groundwater/surface-water exchanges; the latter would also be informed by tracer studies and streambed surveys. Use of transient simulations, calibrated with transient measurements, is suggested to provide an independent estimate of the storage capacity of the mines."

How does this apply to the Marcellus Shale Play?
1. Mine Drainage may be the perfect surrogate raw water for Marcellus and other Unconventional Gas.
2. The concept
a. Select natrual or induced minewater discharge areas near existing wastewater treatment plans, raillines, or other accessible areas. It would be best to use rail rather than hauling or pipeline installed along rail right-of-ways.
Phase I
a. Rank Sites and Characterize Sources
b. Interpet Minewater as Natural or Artifical Discharge Points and install a rapid treatment module to aerate the water and remove iron and manganese. Collect iron and managense oxides and use as a raw material for treating other waste streams.
c. Send this water by rail or pipeline to Fracwater Treatment Areas or a central storage area.
d. Blend the fracwater and AMD waste streams
e. Repeat-
Phase II - Use a portion of the revenue to install passive treatment systems.
Phase III- Discontinue use of the fluid for hydraulic fracturing, but use the passive systems to treat natural discharges and pipelines to faciliate the movement of production water for treatment.
Phase IV - Use the water to reclaim abandon mine lands by helping to establish a native grassland - growing switchgrass and other native grasses. Harvest these grasses as a future sustainable field. My reclaiming the land - we are also helping to reduce the volume of acid mine drainage.
