Water pollution and its impact have become major environmental concerns nationwide. Driven primarily by Federal Clean Water Act (CWA) and Safe Drinking Water Act (SDWA), our water resources services focus on both surface (i.e., lakes, streams, wetlands, and rivers) and groundwater.
EGS works with clients whose projects may impact nearby water resources and determine quality, quantity, and other aspects so that mitigation, monitoring, and overall management plans can be effectively implemented.
CWA introduced the National Pollutant Discharge Elimination System ( NPDES), which is a permit system for regulating point sources of pollution. Point sources include:
- Industrial facilities (i.e., manufacturing, mining, oil/gas extraction, and service industries)
- Government facilities including local, and
- Some agricultural facilities.
The NPDES permit is required for point sources, and this system is managed by the United States Environmental Protection Agency (EPA) in partnership with state environmental agencies.
EGS assists industrial facilities and government facilities in protecting and managing resources and achieving a sustainable solutions. In order to control both point and non-point sources of water pollution, major federal and state laws need to be followed and implemented.
EGS services include:
- CWA Section 404 permits
- 401 water quality certification
- National Pollutant Discharge Elimination System (NPDES)
- Stormwater Pollution Prevention Plans (SWPPPs)
- Water Conservation Plan
- Water resource management and storage
- Water quality monitoring
- Stormwater inspection services
- Water resource management and planning
- Drinking water source protection plans
- Public drinking supply water well design and installation
Groundwater is one of the Nation’s most important natural resources and serves as domestic potable, industrial, irrigation water supplies.
The threat to groundwater is considered a constant serious problem. Water resources development and shortage issues in high-growth regions are among today’s leading groundwater problems.
Groundwater pollution is one of the serious and complex forms of contamination, and only groundwater experts can provide sound scientific and business solutions.
Groundwater protection provisions are included in the SDWA, Resource Conservation and Recovery Act (RCRA), and the Superfund Act (Superfund).
Our knowledge of fate and transport processes combined with groundwater flow (numerical) modeling experience enables us to address problems from salinity impacts to plume migration. We provide our clients with quantitative hydrogeologic data analyses and engineering design evaluation for sites undergoing investigation and remediation phases.
Groundwater contamination can occur in numerous ways, and EGS’s highly experienced professionals will solve most of the complex problems by providing services in the following areas:
- Groundwater Hydrology;
- Groundwater impact assessment and mitigation;
- Aquifer Characterization and tests;
- Contaminant Fate and Transport;
- Groundwater Numerical Modeling;
- Groundwater Remediation Design; and
- Performance Monitoring of Active Groundwater Remedial Action (GWRA).
