    Algae in the water column: Tiny microscopic algae are often present in the water column, giving the water a green (or brown) tint. Look for greenish colored water (L) or tiny clumps of algae floating in the water column (m). Pea-green waters (R) are an indication of an algal bloom.

    Harmful algal bloom suspected?

    If your water is abnormally greenish colored, you observe many floating algal colonies or if there are any spilled-paint like scums present, you should suspect a harmful algal bloom. Follow the “Steps to Take if You Suspect a Harmful Algal Bloom” document to collect a 1L sample, photograph the bloom, contact the authorities and transport the sample to a local scope for analysis.
