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.

Waterwise Wednesday: Levees of Leaves

  Falling leaves signal the official arrival of Autumn. Put leaves to good use as insulating mulch in a garden bed, make them into compost, or shred them across the lawn as a natural fertilizer. Left to lie in gutters, leaves quickly clog storm drains leading to flooding in a Fall storm and nutrient pollution as the leaves degrade in the storm sewer. Pile ’em up and enjoy the benefits of leaves next spring!

Waterwise Wednesday: Reading Coffee Rings

The coffee ring could be a new test for drinking water quality. Tap water leaves distinct patterns and whorls its dried residue, like a coffee ring. The markers indicate water hardness and alkalinity, as well as the presence of dissolved solids and metals.

Researchers at Michigan State University hope the ‘Coffee – Ring Effect’ will provide an inexpensive and accessible way for people to identify traits in their drinking water.

Waterwise Wednesday: It’s the Rules

For many people, taking care of the environment is common sense. It’s also required by law.

Scottsbluff operates under the National Pollution Discharge and Elimination System (NPDES) Phase II Municipal Separate Storm Sewer (MS4) General Permit. The permit

encompasses six general areas:
– Public Education and Outreach
– Public Involvement
– Illicit Discharge, Detection and Elimination
– Construction Stormwater
– Post-construction Stormwater
– Good Housekeeping/Pollution Prevention for Municipalities

The city’s stormwater surcharge not only pays for MS4 infrastructure but also the programming that educates residents and become active in pollution prevention and preserving water quality.

Waterwise Wednesday: Beware of the Toxic Algae

Blue-green algae can house cyanobacteria that causes illness ranging from mild rash to death in both humans and animals. Blue-green algae forms a scum like pea soup or paint on the surface of the water during the summer and fall. While most blue-algae is harmless, the cyanobacteria is not.

Nebraska monitors 52 public beaches May 1 to September 30 each year, including Lake Minatare, and posts current warnings on the webpage below. Cyanobacteria cannot be seen with the naked eye, so it’s recommended to avoid contact with blue-green algae blooms and to prevent pets from drinking or swimming near them.

Waterwise Wednesday: The Heat is On

 

It’s mid-summer, Panhandle temperatures rise and both the landscape and drought map begin to turn yellow and gold. According to the Drought Monitor, Scotts Bluff County is now experiencing abnormally dry conditions.

The water we use now greatly affects the supply we have in the future – especially if drought conditions spread and continue. Scottsbluff’s water system relies on groundwater pumped through wells, instead of surface water, which replenishes very slowly. Dry or drought conditions cause less regeneration of the ground water supply. Please use water wisely and conservatively.

Waterwise Wednesday: Feeding the Blue-Green Algae Monster

“..in the St. Lucie estuary, about half the sea grass, which is a food source for many marine animals, died off during last year’s algae blooms. Among humans who’ve been exposed to the algae, there has been an increase in antibiotic-resistant staph infections. Florida’s governor has declared a state of emergency in four counties,” according to Janice Kaspersen, editor of Stormwater: The Journal for Surface Water Quality Professionals.

Fertilizer in water runoff is boosting the growth of blue-green algae and hurting more than Florida’s $109 billion a year tourist industry. Cyanobacteria flourish with phosphorus and nitrogen, primary ingredients in fertilizers. The fertilizer boosts growth that create large algae blooms during summer and fall that deplete oxygen and diminish sunlight in the water. The bacteria not only affect aquatic life but also cause beach closures for health safety.

Fertilizer is one of the largest pollutants of stormwater runoff in urban areas. Please use fertilizers “sparingly and caringly” – apply according to the directions, when wind is still, and rain is not in the immediate forecast. You’ll be protecting more than just your plants.

Waterwise Wednesday: The Water’s On

It’s nearly July and the gardens are green and full of early summer blossoms – using just rainwater.

Late last week the City of Scottsbluff finally turned the water on the downtown gardens, about three months after lawn watering began around the city. Native and well adapted plants use much less water than traditional turf once established.  They’re also drought hardy, provide needed habitat for pollinators and create a distinct sense of place with a plant palate tailored for the Nebraska Panhandle.

Waterwise Wednesday: Too Wet

Many lawns are over-watered leading to root rot, shallow-rooted plants and the spread of fungal growth on the grass. Horticulturists agree that lawns should get no more than 1 inch of water per week, including rainfall. An empty can placed on your lawn can be used to measure accumulation and moisture sensors attached to automated systems can help prevent over watering.

Waterwise Wednesday: What a drip!

Drip and emitter systems conserve water by regulating volume, velocity, and direction of water flow. Plants can be targeted with a slow steady specific quantity of water using drip tubes or emitters. This prevents over watering and watering where not needed. And the systems are discreet, designed to function effectively while lying under a layer of mulch.
