Section Env-Or 606.05 - Summary of Subsurface Explorations and Sampling The site investigation report shall include a summary of subsurface explorations and sampling conducted at the site and off-site surrounding area including:
(a) A description of test pits, borings, monitoring wells, and well development activities;(b) A description of water table elevation observations, organic vapor analyzer results, and odors noted;(c) A copy of the site plan showing the orientation of the graphical geologic cross section(s) and the location of test pits, borings, monitoring wells, and other sources of geologic information for the site;(d) Groundwater, soil, air, soil gas, sediment, surface water, and water supply well sampling data, as applicable, including: (1) Sampling methodologies;(2) For all monitoring wells, surface water sampling points, and water supply wells where contamination has been detected, analytical results for a minimum of 2 sets of samples collected at least 2 weeks apart; and(3) At sites where groundwater contamination has been detected, samples collected from water supply wells at risk;(e) One or more tables that summarize all current groundwater, soil, surface water, and water supply well analytical data including: (3) Chemicals detected including the analytical detection limits;(4) Chemical concentrations; and(5) Chemicals that exceed regulatory limits;(f) One or more tables that summarize historic groundwater, soil, surface water, and water supply well analytical data including:(3) Chemical concentrations; and(g) A description of all other methods used to evaluate subsurface conditions as appropriate, such as:(2) Geochemical analyses;(3) Cone penetrometer; and(4) Fracture trace and photo lineament analysis.N.H.
