0 9 Beckman Road Page 22 of 24 Our Project Number: LES140024 September 12, 2014 • Groundwater in the northern portion of the site contained elevated levels of TPH- Gasoline, TBA, MTBE and TAME in a 2003 on-sitt sampling event. No constituents of concern were detected in the most recent 2010 sampling data. • Buildings on the property were built around 1967. • The subject property has been used for agricultur I purposes prior to 1966. Pesticides may have been used on the property. • Mosquito abatement ponds were located on the property. Pesticides may have been applied in these areas. • An in-ground hydraulic lift with visible corrosion is located in the shop area of the site. • Twenty-one (21) leaking underground storage tank cases were identified within one-half mile of the subject property, including the northern adjacent/up-gradient former Shell Station at 880 Victor Road that historically impacted groundwater at the subject properly • Thirteen (13) hazardous materials cleanup and/or remediation cases were identified within one-half mile of the subject property (one mile for cases on the NPL or state equivalent). • Three (3) hazardous materials handlers were identi ed adjacent to the subject property. • Three underground storage tank facilities were identified adjacent to the subject property, one currently has LISTS. 7.2 Opinions • The subject property is located on several data ases, due to the former LISTS and associated releases. No Further Action and Tank Closure Letters have been issued; however, the soil tested 11 years ago indicated ele ated levels of petroleum constituents are present at 30 feet bgs. This contaminated Soil remains in the subsurface. This constitutes a REC. • The staining at the property is considered de min#Ws. • Kleinfelder tested soil for pesticides at multiple locations on the site, including the ponds, as part of their Phase II investigations. No aesticides were detected on the site. Therefore, former pesticide use is not a concern. • The hydraulic lift on the subject property is old and corroded, and may have leaked. The lift indicates automotive maintenance activities took place on the property. This is considered an REC. • Previously impacted groundwater in the northern portion of the site is likely due to contamination from the closed LUST at the northern adjacent/up-gradient former Shell gasoline station at 880 Victor Road, rather than on-site UST releases. The most recent (2010) data indicates no remaining impact to the site. However, if another release were to occur from the replaced USTs, groundwater at the site would likely be impacted. The past and potential future impact to the subject property constitutes an REC. • The other cases identified in the vicinity of the property, excluding the adjacent gas station at 880 Victor Road discussed above, appear unlikely to impact the subject property at this time due to their distance from the subject property, the sampling data reviewed, and/or the nature of the case. 02014 Neil O.Anderson&Associates.Inc.
