Water Quality Monitoring for the
“Big Four Parameters”
Many different parameters can be measured in natural and artificial waters with sensors or via lab analysis. Each parameter effects water quality and the organisms that depend on the water for survival. Different states, monitoring agencies, and companies also place an emphasis on different water quality parameters to be monitored, depending on local conditions and mandates.
For most water quality professionals, in-situ measurement of temperature, dissolved oxygen, electrical conductivity, and pH are considered the standards for basic water quality testing, and are referenced in many official Government guidelines.
Stevens Water Monitoring Systems offers several products that make monitoring these parameters a simple task, providing accurate data for decision making.
Continue reading the article online to learn more about these different parameters, how they affect water quality, and what equipment is typically used to measure these parameters effectively.

Hydrolab MS5 Water Quality Sonde
Ideal for monitoring several water quality parameters simultaneously while still maintaining a small physical size, The Hydrolab MiniSonde 5 offers an optimized selection of Hydrolab’s superior sensors (Temperature, DO, Conductivity, and pH plus additional sensors) in a compact and lightweight multiprobe designed for either profiling or unattended monitoring.
The MS5 comes with four built-in expansion ports, and can measure up to 10 water quality parameters simultaneously. The small 1.75” diameter of the MS5 allows it to work in wells and boreholes as small as 2 inches in diameter, allowing high-quality measurement of groundwater applications.
Long-term unattended operation can be achieved by pairing the MS5 with the internal battery pack option. The sensor can record up to 120,000 individual readings in internal memory.
Communication options for the MS5 include SDI-12, RS-232, and RS-485, allowing connection to most data loggers including the Stevens DataLogic 3000 data logger.

Stevens Hydra Probe Soil Sensors
Deployed in Florida Swamp
for Restoration Study
Coastal wetlands provide a large number of critical functions that benefit the surrounding ecosystems and the neighboring human population centers. Coastal flood plains and wetlands help prevent the flooding and destruction of coastal communities by storm surges, acting as a natural buffer to protect communities near the coast.
The bald cypress (Taxodium distichum) is one of the dominant tree species of southeastern coastal floodplains, but is sensitive to changes in water quality, such as salt water intrusion. Many human activities, such as reduction in stream flow from dam diversions and municipal withdrawals from coastal fresh water aquifers have caused harm to these ecosystems.
A four-year study was recently completed which utilized the Stevens Hydra Probe Soil Sensor to collect groundwater moisture and salinity data from Florida’s Loxahatchee River floodplain.
Conducted by Dr. David Kaplan and Dr. Rafael Muńoz-Carpena of the University of Florida’s Department of Agriculture and Biological Engineering, useful relationships between river channel flows, soil moisture and porewater salinity were developed to better predict the effects of proposed restoration and management scenarios.
