Sampling and Monitoring Instruments for Water Quality, Level, and Solutions

It was the start to a particularly eventful summer. Another summer where harmful algal blooms, red tides, beach closings, and images of dead sea-life dominated the news and became part of our summer lexicon.One recent summer in particular, saw a toxin from a harmful algal bloom form and eventually contaminate the drinking water source for the City of Toledo, Ohio. Eventually prompting a ‘do not drink’ order.

A wilderness teems just out of sight in rivers, actually below the rivers in the saturated soils, gravel, sand and rocks under and along the river’s main channel. This is the hyporheic zone: an entire zone where functions vital to the overall health of a stream and watershed take place.

The City of Lafayette water resource recovery facility (WRRF) utilizes instrumentation as part of the their infrastructure to improve water quality, protect the community, and enhance their sustainability. As part of their laboratory, field sampling, and online process monitoring and control instrumentation they choose YSI.

It was the beginning of a particularly active year. In fact, this activity had been occurring for many years…but the causes were largely over looked by many. Extreme weather events decimating lives… Rising sea levels destroying infrastructure... Frequent flooding causing millions in damage and claiming lives. And failing flood control systems. The Power of Water - is the will of water.

It was the end of an exceptionally dry year. In fact, it was the end of an exceptionally dry decade. A decade that saw increasing global and ocean temperatures. A decade that dealt with more frequent and devastating wildfires. And, a decade that continued to see women, in Africa alone, spend 40 billion hours each year walking in search of water. Water scarcity is an issue that affects a majority of the population.
