PROJECT: |
2008 - ISRA Plant Cessation With Site Remediation And Historic Fill |
SITE: |
Paramount Machine & Tool, Fairfield, NJ, Essex County, NJ |
ATTORNEY: |
Lou Bertoni, 973-809-6472 |
PROJECT VALUE: |
$118,000 |
DETAILS: |
Initially hired to prepare GIN and Preliminary Assessment filings in compliance with ISRA requirements, several areas of environmental concern triggered a Geoprobe based Site Assessment. A few of the machine tools were observed to be leaking into concrete floor expansion joints. Soil samples confirmed impact to soils beneath the concrete floor. ANCO performed soil remediation work during plant operation hours, extracting 80 tons from two areas. ANCO then filled, compacted and restored all concrete surfaces to specification. A review of historic topographic maps revealed imported fill, which was probed and mapped during an on-site visit by Bill Goodman and Josh Gradwohl, the NJDEP case workers. Abandoned septic tank closure at the two involved lots completed the project. The project was initiated in Dec. 2007 and the NFA determination was issued in Jan. 2009. |

2008 - Dry Cleaners PCE Remediation With Helical Piles And SVE Technology |
SITE: |
New Providence, Union County, NJ, ANCO Project #15225-RW |
CLIENT: |
Real Estate Holding Company |
OVERSIGHT CONSULTANT: |
Environmental Liability Management (ELMI), 609-683-4848 |
PROJECT VALUE: |
$289,000 |
DETAILS: |
PCE had diffused deeply through poorly graded, water saturated unstable (95% silty) soils beneath this dry cleaning facility at a strip mall. The foundation was supported on two sides with Chance helical pull down piles set by ANCO. Four helicals were set on the inside of the building due to a 4” gas main routed along the exterior wall. Helicals were set immediately following digging a narrow section utilizing a small excavator with a quick connect coupling. This enabled simply and efficiently switching from excavator bucket to helical torque driver. Contaminated soil was excavated to a depth of 10’ below grade; 4’ deeper than the water table. Twice daily excavation dewatering coupled with soil digout and material staging was a logistic challenge while this busy mall remained open for business during the entire process. Vapor extraction piping was installed through horizontal boreholes set through the excavation sidewalls beneath adjoining businesses. SVE gasses were pumped through activated carbon drums through plumbing configured by ANCO. |

2008 - Deep Oil Penetration Through Coarse Sand At Tight Urban Site |
SITE: |
Summit, Union County, NJ, ANCO Project #14976-RW |
CLIENT: |
American Legion Post |
OVERSIGHT CONSULTANT: |
None – See attached letter of recommendation |
PROJECT VALUE: |
$54,000 |
DETAILS: |
With a pending real estate transaction set to expire, timely and effective job progression was paramount. The 1,000-gallon active leaking underground oil tank had been set inside and old cistern, with a leaky bottom. The soil type to the 21’ dig depth was coarse sand, so oil had an unimpeded pathway along foundations to a point at least 4’ deeper than the adjacent building footings. ANCO Geoprobed to 26’, and the next day a wellpoint failed to reveal water. Steel sheet shoring was driven to protect the neighboring building foundation. ANCO removed a fire escape and temporarily supported a three-story porch during construction. 83 tons of oil saturated contaminated soil were excavated. Total cleanup cost $54,000. Client satisfaction level: Ecstatic. |

2002 - Emergency Spill Response Due To Truck Overturn Into Pond At County Park |
SITE: |
Mountainside, Union County, NJ, ANCO Project #9038-ER |
PROJECT VALUE: |
$32,000 |

DETAILS: |
An 80,000 lb. truck ran off the road into a small pond at the Watchung Reservation. The contents of his saddle fuel tanks quickly leaked into the otherwise pristine ecological receptor. ANCO boomed the spill utilizing boats and skimmed the oil off the water surface, first with oil absorbent spill pads, then with compressed air plus vacuum trucks to extract free product. The truck had crashed through a guardrail thusly ripping fuel lines thereby affecting soils. ANCO’s wide track excavator was utilized to dig silty organic surfacial soils from the affected bog. |
PROJECT: |
2001 - WWII Era Machine Shop Contamination Discovered During Redevelopment |
SITE: |
Palisades Park, Bergen County, NJ, ANCO Project #14625-SI |
CLIENT: |
Palisade Park Plaza |
PROJECT VALUE: |
$148,000 |
DETAILS: |
During the course of excavating footings for a parking garage, highly odiferous soils, along with metal shavings, were encountered at a location immediately next door to a day care center. The next day free product, determined to be cutting oil, was observed pooling in the excavation. Historic aerial photos plus Sanborn Maps revealed the metal working history of the site. Apparently metal cuttings were simply discarded out the rear door and used to fill in a low spot, leaching PAH compounds and metals became the secondary problem, revealed through the course of the ensuing groundwater investigation. Enhanced fluid recovery through monitor wells with an interceptor trench was the means by which hydraulic control was maintained. A total of 860 tons of material was excavated from this site which received an NFA letter on January 5, 2009 |
PROJECT: |
2000 - Former Oil Terminal Demolition And Remediation And CEA Management |
SITE: |
Springfield Township, Union County, NJ ANCO Project #8626-RW |
CLIENT: |
Springfield Township – Bruce Bergen (Township Attorney) 908-276-8855 |
PROJECT VALUE: |
$145,000 (ongoing) |
DETAILS: |
ANCO was retained in 2001 to address any NJDEP requirements needed to prepare the former Shiable Oil Company site for site redevelopment as a township firehouse. While the tanks had been removed, and a limited amount of soil remediation work was performed by another environmental company, the site was still heavily contaminated with heating oil and gasoline. Free Product was found beneath site structures and floating on the water tale. ANCO demolished the structures, removed a significant quantity of asbestos containing material, excavated 350 tons of contaminated soils, then performed open pit free product extraction. ANCO installed six monitor wells, implemented a detailed multiple monitor well based Remedial Investigation Workplan, and performed an ecological receptor evaluation which resulted in the issuance of a classification exemption area with an eight year duration. The project is currently up for its biennial recertification, and is under directive for continued investigation. The project is ongoing. |
