Cyanobacteria Screening

If bloom observed, a sample may be screened in several ways to determine if more quantitative analysis is necessary:

Sample analyzed with handheld fluorometer. This device will measure the phycocyanin and chlorophyll a pigments to detect the presence and abundance of cyanobacteria.

Microscopic analysis to identify and confirm the presence of cyanobacteria taxa in the sample.

Actions

If field survey screening indicates a likely bloom, samples will be collected for laboratory analysis of cell density and toxins.

If a confirmed Harmful Algal Bloom is present with levels quantified at or above the NJ Health Advisory Guidance, BFBM and DWM&S management will be alerted and a monitoring plan will be developed.

May include follow-up sampling in the frequency and duration necessary to confirm the continued presence or absence of the initial bloom.

Lake Monitoring Network

BFBM's Lake Monitoring Network collects ambient water quality information for NJ lakes consisting of three components: Statewide statistical (probabilistic) survey, statewide reference lakes, and targeted regional lakes. If a bloom is suspected at a Lake Monitoring site, appropriate response actions will be taken.
