Testing. Collaboration. Action.
Objective #1 -related work continued in 2023, sampling at stormwater pipe outfalls that empty into the Shark River inlet/estuary, testing for the presence of fecal indicator bacteria. In early 2023 we analyzed the 2021-2022 data and confirmed that our methods were sound, so we upgraded our analysis method from the EPA-donated equipment to an NJ DEP Certified Laboratory. Donations to our program supported the direct costs of analysis. 2023 results for all monitoring stations were reviewed with partners at NJ DEP, and deemed valid and in some cases - potentially actionable. In late 2023 and early 2024 we began direct outreach to municipal stakeholders in the watershed area to review our initial results.
In 2023, we also introduced a pilot Objective #2 to monitor for fecal indicator bacteria in Jumping Brook, major freshwater tributary to Shark River. Analysis of this preliminary data continues.
Quality Assurance Project Plan
We created a Quality Assurance Project Plan (QAPP) - a detailed plan to generate clear and quantifiable data by following consistent and scientifically valid process. The QAPP was reviewed by experts at US EPA and NJ DEP.
Testing sites were selected based on historical sampling data by the NJ DEP Bureau of Marine Water Monitoring.
Sampling Process
Samples collected directly into sterile bottles using a dip pole.
Sampling at low tide to help isolate direct effluent water from the stormwater pipe.
Data recorded: temperature, smell, appearance.
Cleaning steps to prevent cross contamination.
Samples put on ice during transport to prevent bacteria growth before analysis.
Analysis 2023 - Program Expansion
Water samples analyzed at an NJDEP certified lab for for Fecal Indicator Bacteria – enterococcus.
Pilot program testing at two upstream freshwater locations in Jumping Brook for e. Coli bacteria.
