Waterwise Wednesday: The Ultimate Water Filter

Earth’s water cycle constantly refreshes our water supply as it travels through (the basic) phases of precipitation, evaporation, and condensation. We depend on the water cycle to bring us fresh, clean water.

Our water can only be as clean as it’s filters. Damage of soil, air, or ground surfaces also damages the filtration or renewal of water.

Greenhouse gases affects the amount, distribution, timing, and quality of available water which affects our activities like recreation (fishing, hunting, water recreation), farming, manufacturing.

Contaminants left on the surface or in the soil contaminate groundwater as it soaks through the soil, requiring additional filtration for humans to drink.

Every person can help prevent pollution, which helps keep the water cycle flowing smoothly and our water clean.

Downspout Redirection

Downspouts directed towards natural areas, such as yards or flowerbeds, allow the runoff to infiltrate and be used to its full advantage. This action also helps reduce the volume of runoff and amount of pollutants that enter the storm sewer system, which get sent directly to receiving lakes and streams.

Waterwise Wednesday: Policy Works

Researchers, led by Estelle Chaussard from the University of Buffalo, link ground water recovery in Santa Clara Valley California to the state’s newly instated water conservation efforts—policies that diverted surface water to refill aquifers

In 2013, interferometric synthetic aperture radar (InSARa) measured a 2-centimeter decrease in ground-level elevation, followed by another 3 centimeters in 2014. The research team estimates a groundwater loss of about a tenth of a cubic kilometer caused the ground to shrink or lower.

Ground surfaces began to expand and rise in September 2015, rising nearly 2 centimeters over the next two years and were at pre-study levels by the end of 2016. This reflects the same time surface water diversion policy went into effect.
