O i f th N J W tOverview of the New Jersey Water Tracking Model
New Jersey Water Transfer Data Model or NJWaTrMi ft A d t b– Microsoft Access database
The tracking model is New Jersey’s tool for storing and analyzing QA/QC’d water datay gConsolidates data from multiple regulatory programs and databases Includes geologic, hydrologic, owner, use, permit, location and volume data
O i f th N J W tOverview of the New Jersey Water Tracking Model con’t
Readily allows data additions and links to GISC b d d l th t li k t thConveyance based model that links together withdrawals, uses and discharges with one-way conveyancesyUtilizes a template loading structureDeveloped in 2002 with NJ USGSMajor updates in 2004, 2009 and 2010 to model and dataSimplified DataWarehouse and DataMart mdbsSimplified DataWarehouse and DataMart mdbs available
NJWaTr Now Contains
1990 through 2007 monthly data1 2 million monthly withdrawals from 15 000 wells1.2 million monthly withdrawals from 15,000 wells and intakes
– NJ’s Water Allocation permitting program– domestic well estimates by municipalityy p y
675 water purveyors– 20,000 monthly bulk transfer between purveyors
70 000 monthly discharges70,000 monthly discharges– Sanitary sewer surface water and groundwater discharges
(>20k gpd)Estimates of consumptive (evaporative) and p ( p )depletive (export) losses
