WESTON’s Baseline Experience
• Performed Baseline Sampling in:
• Pennsylvania (regulated)
• Ohio (regulated)
• Texas (voluntary)
• Colorado (voluntary when performed, now regulated)
• Designed Baseline Programs for:
• Regulated and Voluntary Regimes
• High and Low Volume Drilling Plans

What is Baseline Sampling?
Baseline Sampling – The process of collecting water samples from sources surrounding a well pad to document groundwater conditions prior to drilling.

Establish Program’s Goals
• Risk Management
• Provides documentation of pre-drilling groundwater conditions
• In some States, can satisfy regulatory requirements that also provide operator with some liability protection
• Regulatory Drivers
• Required to obtain drilling permit in Ohio
• Mandatory in some States
• Stakeholder Engagement
• Shows landowners that the Operator is taking care in how they do business

Geographic Scope
• Is Program for one operating unit or multiple/all?
• What should be consistent across geographies?
• Consider local logistics

What to Sample
• Public and private water wells
• Surface water sources
• Seeps and springs
• Agriculture, livestock and potable sources

Where to Sample
• No consensus among operators or state guidance
• Generally surface hole location used as the starting point
• ½ to 1 mile radius?
• Enough samples to berepresentative

Obtaining Permission to Sample
• Initial contacts best done over the phone or in person, when possible
• Written permission to be on property required
• Be ready to explain why samples are being collected
• Offer to provide analytical results to the landowner
• Be ready for the question:
o “When are you coming back to sample after drilling?”

Analyses to Perform
• Highly Regional – Driven by Program Goals
o General Chemistry
o Anions - Cations
o Metals
o Dissolved Gasses
o BTEX
o TPH

Managing Information
• High-quality data is critical to the program
• Recommend the use of a database
• Plan to manage the data before you need to manage the data
o The amount of information stranded in spreadsheets can be overwhelming
