4-Log Virus Inactivation of Treatment Facilities
A family-oriented camping facility in New Jersey has its own water supply system that provides water service to approximately 175 transient individuals and 1 residential home using three (3) water supply wells. The campground experienced repeated positive sample results for Total Coliform (TC) bacteria and E-Coli (EC) bacteria. Subsequently, the client was issued a Notice of Non-Compliance for TC. After receiving subsequent positive results for TC and EC bacteria, the client was issued a Ground Water Rule (GWR) Corrective Action Plan (CAP) from the NJDEP. GPM Associates (GPM) assisted with preparation of the response to the CAP and design and permitting for 4-log virus inactivation treatment systems for the three (3) potable water supply wells. GPM completed the design and permitting documents within 1 month and worked with the NJDEP through successful completion of permit acquisitions and construction. GPM’s services also included updating the CAP, preparing and submitting project status reports to the NJDEP, and preparing and submitting an initial Ground Water Protection Plan (GWPP). The new 4-log virus inactivation treatment systems included new sodium hypochlorite solution feed systems, chlorine contact pipe, instrumentation and controls. In addition, GPM assisted the Owner and the licensed water operator in providing all other required water system data and information including updated water distribution plans, GIS mapping, and water and wastewater system evaluations. The system was placed into service only 6-months after GPM was retained by the client for this project. Upon the new facilities being placed into service, the water system was brought back into MCL compliance for TC and EC Bacteria and the campground was able to successfully reopen in time for the late spring/early summer camping season.
School Water Treatment Improvements
An independent college preparatory boarding in New Jersey owns and operates its own Public Community Water Supply System, which provides water service for approximately 1,000 residents through 82 water service connections. This existing water supply system consist of four (4) groundwater supply wells. One of the wells and its treatment facility was located in a low lying deciduous area on the campus with a finished floor elevation that was set at approximately 7 feet below existing grade elevation. Due to the construction conditions and finished floor elevation, access to the existing water treatment building was impeded during heavy flood conditions. The school retained GPM for the design, permitting, and construction administration services for the full replacement of the water treatment facility for the existing well. The new building was designed by GPM to meet of the applicable planning and zoning board approvals of the Township as well as aesthetically match the existing campus buildings that were mostly built circa 1800 - early 1900. GPM provided all design and permitting, construction administration and inspections and start-up of the new water treatment plant.
Municipal Water System Master Plan
GPM has worked on several well and water system projects for a municipality in Cumberland County, NJ. We competed a Water System Master Plan (WSMP) for the municipality, including analyzing the existing water system concerning water supply, water treatment, water storage, water transmission and water distribution. Projections for the future water needs for the municipality were made with the assistance of the county planning department. The WSMP utilized a hydraulic model of the water system we designed. The existing municipal water system has no atmospheric storage and is, therefore, a closed system. GPM made the recommendation to construct a new elevated storage tank in the western portion of the municipality and the WSMP determined the MSL height of the overflow for this proposed tank. This new hydraulic gradient allows for the elimination of the existing higher pressure area of the existing water system. The water model was extensively used to determine fire flow availability in various parts of the municipality and determines where bottleneck restrictions in water transmission needs to be addressed and sizes future water main extensions.
Water Infrastructure Improvements
GPM designed replacement wells, upgraded an existing well, and upgraded treatment facilities for a municipal client in New Jersey as part of an infrastructure project, funded through USEDA. The project included the construction of three new 18”x12” diameter steel double-cased replacement wells using the reverse rotary drilling process; retrofitting two new water treatment facilities to provide treatment for specific wells; design (including the preparation of plans and specifications to meet USEDA requirements); NJDEP Bureau of Safe Drinking Water permit acquisition; review of contractors proposals and recommendation of award of contract for construction; project administration; and limited construction supervision and start-up assistance. Worked with USEDA to ensure that all federal and state requirements were met. GPM assisted the same client with another water infrastructure improvements project which included the design of new water booster pumping station facility for the existing 2.4 MG reservoir for another USEDA-funded project. The new state-of-the-art water booster pumping station included three high service water booster pumps with variable frequency drive controllers; retrofitting and connections to the existing 2.4 MG reservoir and existing water distribution system; a new concrete block booster station building; instrumentation and control equipment; and an emergency power generator system. GPM was responsible for all design work including the preparation of plans, specifications, NJDEP Bureau of Safe Drinking Water permit acquisition, review of contractors’ proposals and recommendation of award of contract for construction, project administration through the entire project and limited construction supervision and start-up assistance. Worked with USEDA to ensure that all federal and state requirements were met. The completed project resolved pressure problems throughout the system as well as overall efficiency of the water supply wells and treatment facilities.
Hydrogeologic Services and Water Allocation Permitting
GPM provided the design, hydrogeologic reporting and water allocation permitting for a new water supply well for a municipality. GPM sited the well, arranged for a pre-application meeting with the NJDEP Bureau of Water Allocation and the New Jersey Geological Survey, prepared a complete test well design including development of an aquifer pumping test that was approved by the Bureau of Water Allocation, prepared bid specifications for the new test well, monitored wells and conducted a pumping test, reviewed bids and provided a recommendation on award of contract. We provided construction administration and inspection services throughout construction of the new well, including coordination with the NJDEP Bureau of Water Allocation and the New Jersey Geological Survey during the pumping testing phase of the project. Upon completion of construction and testing of the new well, GPM analyzed the pump test data and prepared a hydrogeologic report, an engineer’s report, and complete application to the NJDEP Bureau of Water Allocation for a major modification to the municipality’s existing water allocation permit for an additional well.
For another municipality in New Jersey, GPM assisted with obtaining permits for a well and facilities, completing and submitting an application to the NJDEP Bureau of Water Allocation for modification of the municipality’s existing Water Allocation Permit, including an additional well and a proposed well. We prepared the required hydrologic report, application forms, and handled all correspondence with the NJDEP Bureau of Water Allocation during the permitting process. GPM worked with the municipality with preparing and organizing a list of proposed development projects that were used in calculating future demands to provide for justification for the increase in water allocation for the municipality. The water allocation permit modification was approved and provided the municipality with the much needed diversion rights for existing and future water demands. (Image courtesy of NJDEP)
Radium Removal Treatment Facility
One of the wells for a municipality is rated for 1,400 gallons per minute and is an essential part of the existing water supply system. Like other water supply wells throughout the municipality, in recent years radionuclide levels have been increasing in the well to the maximum allowable contaminant level. GPM provided design permitting and construction phase services for a new radium removal treatment plant addition for the existing well. We prepared planning documents and assisted the municipality with completing a loan application with the NJDEP and New Jersey Environmental Infrastructure Trust to secure funding for this project and all NJDEP and Municipal Approvals, as well as assisting the municipality with bidding process for construction. GPM also provided construction phase engineering services, including shop drawing review, review of payment requisitions, limited site inspection, proving technical and start-up assistance, and all coordination work with the NJDEP Municipal Finance and Construction Element.
For the same municipality, another well is rated for 2,000 gallons per minute and includes an existing ion exchange radium removal treatment system and absorptive type radium removal treatment system for the ion exchange wastewater discharge. In order to eliminate the high operation costs for this facility, including the treatment of the wastewater treatment system, the municipality has implemented a plan to upgrade the existing well treatment facility to include a new replacement radium specific absorptive type radium removal treatment system which does not include chemical additions, regeneration or generate any wastewater discharge, thereby eliminating the need for the existing, costly, wastewater treatment system, GPM provided the design permitting and construction phase services, including preparation of planning documents and assisting the municipality with completing a loan application with the NJDEP and New Jersey Environmental Infrastructure Trust to secure funding for this project. GPM provided construction phase engineering services, including shop drawing review, review of payment requisitions, limited site inspection, proving technical and start-up assistance, and all coordination work with the NJDEP Municipal Finance and Construction Element.
