P I P II VC Ill. ENVIRONMENTAL ASSESSMENT Page 0 0 Lithologic logs for all on-site wells;copies of field log notes NA may be appropriate- 0 0 Well construction diagrams for all on-site wells showing NA screened interval, casing type and construction details including gravel pack, interval, bentonite seal thickness and cemented interval. 0 0 Description of the current and proposed use of on-site 20 ground water in sufficient detail to evaluate human health and environmental risk pathways. In addition, the applicant will provide a discussion of any state and/or local laws that restrict the use of onsite groundwater. The applicant should provide information concerning the nature and extent of any contamination and releases of hazardous substances or petroleum products that have occurred at the site, including but not limited to: + Identification of the chemical nature and extent, both 15 onsite and offsite, of contamination that has been released into soil, groundwater or surface water at the property, and/or releases of substances from each of the source areas identified, including estimated volumes and concentrations of substances discharged at each area,discharge point,or leakage point as per Section 25.16.308(2)(b).Although Phase it assessments identify the nature of contamination,the extent is not always fully defined. For Voluntary Clean-up Program purposes, the source, nature, ! extent and estimated volumes of the release are important in the I overall evaluation of risk and eligibility. 0 0 A map to scale showing the depth to ground water across NA the site, direction and rate of ground water movement across the _ site using a minimum of three measuring points. 0 0 A discussion of all hydraulic tests performed at the site to NA characterize the hydrogeologic properties of any aquifers onsite f and in the area. 0 0 All reports and/or correspondence,which detail site soil, Att. 8 groundwater and/or surface water conditions at the site,including analytical laboratory reports for all samples and analyses. 0 0 A discussion of how all environmental samples were 15 collected, including rationale involved in sampling locations, parameters and methodology, a description of sampling locations, sampling methodology and analytical methodology and information on well construction details and lithologic logs. All sample analyses performed and presented as part of the environmental assessment should be appropriate and sufficient to fully characterize all constituents of all contamination that may have impacted soil, air, surface water and/or groundwater on the property.The applicant should use Environmental Protection Agency approved analytical methods when characterizing the soil, air,surface water and/or groundwater.
