Seasonal Water Quality Monitoring


The New Jersey Sports and Exposition Authority (formerly NJMC) has monitored the quality of water within the District since 1993.  The monitoring project was established to provide a general assessment of overall water quality in the Meadowlands estuary due to the legacy of contamination from the landfills located within the District. The monitoring efforts also identify any large-scale, long-term trends in water quality, and detect any acute water quality problems.

Water samples are collected at 14 sites on the lower Hackensack River and its tributaries every quarter. The map below shows the location of these sites within the district

In the field  the water samples are analyzed for temperature, dissolved oxygen, conductivity, salinity, and pH. The water samples are then brought back to the Meadowlands Environmental Research Institute laboratory for additional analysis.  The parameters being monitored are: ammonia, 5-day Biochemical Oxygen Demand, Chemical Oxygen Demand, hardness, Total Dissolved Solids, Total Suspended Solids, turbidity, fecal coliforms, chloride, bromide, nitrate, nitrite, sulfate, phosphate, sodium, potassium, calcium, magnesium, cadmium, chromium, copper, iron, lead, zinc, manganese, nickel and mercury. The metal species are analyzed for both the total and dissolved forms. The MERI lab is certified by the state of New Jersey and is equipped with the state-of-the-art instruments to perform all these analyses.
