Parameter Collection List

The primary photosynthetic pigment in all algae and cyanobacteria (blue-green algae), and the most direct real-time proxy for algal biomass in a water body.

The accessory pigment unique to cyanobacteria, and the most specific real-time indicator of a developing cyanobacterial bloom.

A composite view: phycocyanin, chlorophyll-a, and supporting variables (DO, pH, temperature) interpreted together to characterize bloom risk.

The acid-base balance of water, expressed on a logarithmic 0 to 14 scale.

The amount of oxygen dissolved in water, the most fundamental indicator of aquatic ecosystem health and treatment process performance.

The water's ability to conduct electricity, a fast, robust proxy for total dissolved ion content.

Oxidation-Reduction Potential, the net tendency of the water to oxidize or reduce dissolved species, in millivolts.

Water temperature, the master variable that controls solubility, reaction rates, and biological activity.

The cloudiness of water caused by suspended particles, measured optically by light scattering.

Total Suspended Solids, the mass concentration of particles suspended in water.

The dissolved fraction of natural and anthropogenic organic carbon, measured by UV-induced fluorescence.

Absorbance of ultraviolet light at 254 nm, the standard surrogate for dissolved organic carbon and DBP formation potential.

Total Organic Carbon (TOC) and Chemical Oxygen Demand (COD), bulk organic-strength metrics, estimated optically from UV254 and turbidity.

Optical detection of hydrocarbons in water, fluorescence-based, no reagents.
