The 101D Water Level DrawDown Meter has all of the same qualities as the well-known 101 P7 Water Level Meter, with the added feature of a drawdown mode. One simple toggle switches between static water level and drawdown measurements. Water level mode allows accurate depth to water measurements in wells, boreholes, standpipes and tanks. The drawdown function is used to monitor falling hydraulic head during low flow sampling, pumping and other aquifer/well tests. It also ensures a pump’s intake remains submerged during purging or well development.
The 101D Water Level DrawDown Meter uses a corrosion-resistant stainless steel probe connected to clearly marked flat tape, fitted on a well-designed reel. It is powered by a standard 9 volt battery. In water level mode, when the zero point on the probe enters water, an electronic circuit is completed, activating the buzzer and light. The depth to water is then read off the tape. In drawdown mode, the circuit is reversed—the buzzer and light are triggered when the probe is in air. The battery test button can check the circuit in both water level and drawdown modes. The on/off sensitivity control allows the buzzer to be turned down in cascading water and ensures a clear signal in high and low conductivity conditions.

Sewage an Unseen and Ignored Threat to Coral Reefs and Human Health
It’s an open, dirty secret that the ocean is used as the ultimate sewage solution. Each year trillions of gallons of untreated waste are sent to the ocean due to a widespread lack of sanitation technology or infrastructure that needs updating as cities and populations grow. As the impact of untreated sewage on the ocean becomes clearer, attention to the problem and strategies for dealing with it have not kept up. “This is a massive problem and it’s been largely ignored,” said Stephanie Wear, senior scientist and strategy advisor for The Nature Conservancy. Wear has turned her attention to raising the alarm about the effects of sewage on coral reefs, which often loses airtime to other pressing issues like climate change and overfishing.

Lake Superior Algal Blooms Surprise, Highlight Need for More Monitoring
In 2012, for maybe the first time, Lake Superior got scummy. Visitors to the Apostle Islands National Lakeshore reported algae washing up on shore around the park. It was a marked shift for the park, made up of a portion of the Lake Superior lakeshore and nearby islands. The water surrounding the park is cold, clear and typically low in nutrients: a combination unlikely to result in algal blooms. But, in 2012 and again in 2018 after violent storms, major algal blooms—ones observed over multiple days—washed ashore and clogged the beaches with unsightly, scummy algae. Not the usual suspects The algal blooms of Lake Superior are not the algal blooms of warmer, more nutrient-rich lakes like Lake Erie.

Unprecedented Changes are a New Challenge for Lake Tanganyika
*This is part two of a series on changing ancient lakes. See part one, Lake Baikal, here . Ancient lakes are facing a suite of rapid, unprecedented anthropogenic changes. While ancient lakes are spread around the world and vary widely from lake to lake, their incredible age, which can reach into the tens of millions of years, makes them unique resources to science. They host incredible biodiversity and long sediment records. They are vital sources of food and water for millions of people. In a changing world, ancient lakes’ value as scientific and natural resources and the incredibly diverse life they contain is under threat.
