Waterwise Wednesday: The Capetown Warning for Metro Areas

Capetown’s crisis is in the spotlight now, but other metropolitan areas could soon follow:

Cape Town’s taps are due to be turned off because of severe drought. It is not alone in having water woes.

Waterwise Wednesday: The Twelve Wells of Scottsbluff

Twelve wells supply the City of Scottsbluff’s drinking water. We have no need to add chlorine or chemicals because of the high quality groundwater. The wells pump an average 4 million gallons a day to supply residents, businesses, and industry within the City.

Because we rely on groundwater it is important to avoid contaminating our supply. Materials like fertilizers, pesticides, gasoline, oil, road salts and chemicals move through soil and seep into groundwater supplies making it unsafe and unfit for human use. Please preserve our water supply with proper use and care of chemicals, cars, and other substances that can contribute to ground, and groundwater, pollution.

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: 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: Controlling Cross Connection Contamination

Cross-connections are actual or potential connections between safe drinking water (potable) supply and a source of contamination or pollution. The submerged hoses in the photos  illustrate a direct cross connection between non-potable water and your drinking water.

A loss of pressure like a water main break or system repair in the public water  system or running too many in-house water sources at once (think shower, washer, dishwasher, and sprinkler system all at the same time) can cause backsiphongage. This loss of pressure creates a siphon effect in the plumbing system which can draw water out of a sink, bucket, or pool and back into your water or public water system.

Cross-connections must be properly protected or eliminated to protect the city’s drinking water supply from backsiphonage or backflow. In this case, either remove the hoses from the pool or barrel or install a hose connection vacuum breaker on the faucet.












Waterwise Wednesday: Spring has Sprung and Lawn Work has Begun!

Amidst the activity, we ask your help in protecting our water quality and MS4 with appropriate fertilizer application. Fertilizer in water causes large algae blooms, hypoxic (dead) zones in water as it decays, and can be toxic to water supply systems. These consequences are easy to prevent with proper application.

Fertilizing Tips:
1. Apply during calm dry weather to prevent spread into unwanted areas.
2. Apply as directed – excessive lawn feeding contributes to ground water contamination.
3. Sweep fertilizer back on the grass if it falls on the sidewalk or other impervious surface to keep it out of the storm sewer.
4. Consider grass clippings or compost as natural alternatives.

Waterwise Wednesday: Seeing Salty Sidewalks

If there is a layer of salt remaining on the driveway or sidewalk after the ice melts, too much salt got sprinkled. If you find excess sand or salt, sweep it up and throw it away so that it is not washed into the storm sewer.

One teaspoon of salt is enough to contaminate five gallons of water forever. Salts, like the de-icers we use in winter, stay in water without settling out contaminating and damaging the North Platte River and freshwater lakes where we fish.

Waterwise Wednesday: What’s Hidden in the Melting Snow

As warmer weather melts the snow piles around town, the runoff makes its way to the city’s outfalls where the contaminants can be seen. The swirled sheen on the water’s surface is oil that was trapped in the snow. Snow traps oils, salts and sediment that are released into the runoff as the snow melts. Snowmelt runoff is one of largest sources of urban water pollution.



Waterwise Wednesday: Five Things You Should Never Put Down a Drain

Clogs from Fats, Oils, and Grease (FOG) are easily preventable:

  • Don’t pour FOG down the drain
  • Pour cooled fats, oils and grease into a container and put the container in the trash. If you don’t have a container, place tin foil into a coffee cup or similar, add FOG, allow to cool and dispose.
  • Before washing, use a paper napkin or paper towel to wipe FOG from dishes and dispose of it in the trash
  • Use sink strainers to catch food waste
  • Put food scraps in the trash, not through the garbage disposal.

This USA Today video from MSN.com shows a few other substances that should also be kept out of the drain: 5 Things You Should Never Put Down a Drain
