Hydrogeological Assessment for Huntington Ready Mix Concrete, Inc.
We performed a hydrogeologic assessment as part of an application to modify a Mined Land Reclamation Law permit.
PWGC assessed the hydrogeologic conditions beneath Huntington Ready Mixed Concrete Inc. and prepared a Hydrogeologic Assessment Report. The purpose of this Hydrogeologic Assessment Report was to document the methodology and results of the assessment, as well as to serve as a supplement Huntington Ready Mixed Concrete Inc.’s application to the New York State Department of Environmental Conservation (NYSDEC) to modify Mined Land Reclamation Law (MLRL) Permit.
PWGC provided the following services:
- Site visit to evaluate existing site conditions.
- Reviewed public records published by the United States Geological Survey (USGS) and the Suffolk County Water Authority (SCWA). In addition, Freedom of Information Law (FOIL) requests were submitted to the Suffolk County Department of Health Services (SCDHS) and NYSDEC for access to records pertaining to private and public water supply well information.
- Contracted Environmental Data Resources Inc. (EDR) to conduct a search of public and EDR proprietary records for potential and/or existing sources of contamination to up to one mile from the Mine.
- Coordinated and oversaw the advance of four soil borings.
- Evaluated soil borings to classify the types of soils located across the site and developed a site conceptual plan identifying the maximum depth of the proposed lake.
- Coordinated and oversaw construction of five monitoring wells.
- Developed and implemented a groundwater sampling plan for the site.
- Reviewed and analyzed on-site groundwater monitoring data to determine the extent of impact that existing mining operations have had on groundwater quality.
- Performed an assessment of the potential sources of contamination to identify the type and quantity of contaminants which could be introduced to the lake from surface spills occurring adjacent to the property.
- Reviewed available reports and data associated with previous investigations performed at the mine.
Sample Projects
