areas on the property for the project. This will typically require the placement of soil borings
and monitoring wells on the property.
8.1.2.2 Sampling Methods
A discussion of the proposed method to be used for soil borings and/or installation of
groundwater monitoring wells must be included. In addition, the proposed number of and
terminal depth of soil borings must be included. If applicable, methodologies for collecting
samples other than soil or groundwater (i.e. surface water, near surface, sediment, etc.) must
also be included.
For proposed strip ROW, direct push technology is the preferred method of soil sampling and
should be utilized to minimize or eliminate the generation of investigation-derived waste.
Proper management and subsequent disposal of investigation-derived waste shall be the
responsibility of the consultant (see Appendix K). Investigation-derived waste shall not be
placed back into the bore hole.
Soil sampling should be conducted in a manner consistent with ASTM D 1586-99. Soil borings
should be abandoned in accordance with the State Coordinating Committee on Groundwater's
Technical Guideline for Sealing Unused Wells, which may be found on ODNR's website.
For properties that will be wholly acquired as part of the project, soil borings and monitoring
wells may be placed using either conventional methods or direct push technology. Monitoring
wells placed on these properties should be permanent wells unless otherwise approved by OES
(Office of Environmental Services). If direct push technology is used, the monitoring wells
should consist of pre-packed well screens. This will ensure the well has a proper filter pack. All
activities should be consistent with OEPA's Technical Guidance Manual for Hydrogeologic
Investigations and Groundwater Monitoring Programs prepared by the State Coordinating
Committee on Groundwater.
8.1.2.3 Field Screening and Sample Selection Methods
A discussion of proposed field screening and sample selection methods must be included. In
general, soil borings should be sampled continuously and one sample from each soil boring
sent to a laboratory for chemical analysis. Selection of samples for analysis can be based on
several factors. All soils being analyzed for VOCs (Volatile Organic Compounds) and/or Semi-
VOCs (semi-VOCs or SVOCs) should be field screened using a PID (Photo Ionization Detector)
or PID/FID. The sample with the highest field reading should be sent for analysis. The sample
