The Water Pollution Control Program was established in June of 1985.  A variety of New Jersey Department of Environmental Protection (NJDEP) delegated work activities are carried out in the twenty municipalities that contract with the MCEHD. These same tasks are also either conducted by MCEHD staff or monitored in the remaining non-contracting municipalities of Middlesex County to ensure compliance with NJDEP/CEHA work.  The Water Pollution Control Program is responsible for the following water pollution activities: well inspections, inspection of non-community water sources, domestic well drilling inspections, septic system inspections, and water monitoring and sampling for both surface water and well water. Additionally, a Geographic Information System (GIS) is maintained in the Water Pollution Control Program to track and map environmental and health threats.
 
Domestic Well Inspections
All new wells and the closure of old wells must be installed or closed by a qualified driller or sealer who is certified by the NJDEP to perform these activities. Prior to commencing work all drillers or sealers must contact the Water Pollution Control Program at least forty eight hours prior to work in order to schedule the witnessing of the procedure by our staff.  All work must be performed according to the following NJDEP regulation: Well Construction and Maintenance; Sealing of Abandoned Wells N.J.A.C. 7:9D.  New wells are to be tested according to the NJDEP Private Well Testing Act, N.J.S.A. 58: 12A-26 ET. Seq. with the results submitted to our office.  All documents are then reviewed and a certificate of compliance is issued for all new well installations.

Other Resources:
Non-Community Water Sources
All public transient and public non-transient non-community water systems are inspected annually by our department to ensure that NJDEP regulations are followed.  These systems are required to adhere to the NJDEP Bureau of Safe Drinking Water (NJDEP –BSDW) regulations. They are required to follow specific water sampling schedules and submit the results to the NJDEP-BSDW.  A zero tolerance policy allows the Middlesex County Environmental Health Division to issue Notice of Violations and Penalty Assessments for systems not in compliance.   For more information regarding these regulations call the NJDEP at (609)292-5550.
A public non-community water system is a public water system that is not a public community water system. There are two types of systems: transient and non-transient.
A “public transient non-community water system” serves at least 25 individuals for at least sixty days in any given calendar year.
A “public non-transient non-community water system” regularly serves at least 25 of the SAME persons for more than six months in any calendar year.

Septic Systems
General Guidelines: All septic work requires a permit from our department.  Permits for repairs are available from our office.  Four copies of both the application and plan must be submitted to our office for review when new construction is proposed.  Direct replacements are allowed as repairs and require a permit from our office.  Any home additions or property renovations require approval from our department.  Refer to N.J.A.C. 7:9A for State law regarding subsurface sewage disposal systems.  Any questions regarding any septic work should be directed to our office at (732) 745-8480.
 
  
Geographic Information System (GIS)
Since 1996 a Geographic Information System (GIS) has been operated and maintained for various mapping activities in the County.  Digital maps are produced and updated using current GIS and Global Positioning System (GPS) hardware and software. This system is used for various projects involving environmental issues and homeland security preparedness.
Some projects have involved mapping of public and domestic water resources in Middlesex County along with the impacts of the Private Well Testing Act (PWTA) in Middlesex County.  Wells affected by natural radium contamination have also been mapped. Sites with environmental concerns in Middlesex County have also been mapped, such as major contaminated sites, closed landfills, and certain state permitted facilities.  The system is compatible with the GIS operated and maintained by the NJDEP.
