BLOG: Groundwater Guardians Go Big on Earth Day

by Sara Brock, The Groundwater Foundation

The Groundwater Foundation’s Groundwater Guardian Program, launched in 1994, has teams across the United States from California to the Carolinas.  Year round, the teams work to increase awareness and education on groundwater issues and on special occasions, like this Saturday’s Earth Day, they get to go big.  Here are 5 communities using Earth Day to bring a little light to this underground resource.

1) Hamilton to New Baltimore, Ohio

Hamilton to New Baltimore’s Groundwater Consortium plans and implements an entire Earth Day Celebration Butler County aimed at increasing public awareness of local groundwater protection efforts.  By collaborating with local environmental groups and educators, they are able to provide over 25 exhibits and demonstrations of the area’s groundwater and surface water protection programs.

2) Lincoln, Nebraska

Lincoln’s Groundwater Guardian team is one of 73 sponsors of the Lincoln Earth Day event.  Schools, private businesses, government offices, and scientists are represented at various booths at this event with local food, music, and speakers. Check out the line-up here: http://www.lincolnearthday.org/ 

3) Valparaiso, Indiana 

The team in Valparaiso is hosting an informational booth at the Northwest Indiana Earth Day Celebration.  As regular presenters at this fair, they are prepared with educational materials and reusable water bottles for the over 2500 people expected to attend this year. If you live in the area, you can even stop by and pick up a rain barrel or compost bin for your home!  Find out more here: http://portercountyrecycling.org/

4) Chippewa Falls, Wisconsin  

Moving away from the fairs and festivals, the Chippewa Falls Groundwater Guardian team puts on a targeted program that, while is still associated with the city’s Earth Day Festivities, provides volunteers with a deeper understanding of and chance to experience groundwater protection in their area.  They do this by attaching “Dump No Waste, Drains to River” buttons on catch basins and illuminating the issue of contamination and drainage in informational sessions before and after. 

5) Central Regional Groundwater Protection Planning Committee, Illinois

The Groundwater Guardian team at the Central Regional Groundwater Protection Planning Committee keeps things running through the weekend with their Clean Water Celebration. Celebrating their 25th anniversary as one of the largest clean water festivals in the world, this year is made extra special by keynote speaker Dr. Jacqueline Quinn, an engineer, inventor, and payload manager for NASA.  Check out the schedule and the speakers here: http://sunfoundation.org/

It’s Water-Wise Wednesdays with Frannie the Fish! {Awesome Aquifer Kit: Exploring Permeability}

This week in Frannie’s exploration of the Awesome Aquifer Kit is all about exploring the key concept of permeability.

For this experiment, you will need water,
a syringe, a timer, sand, and gravel.

Permeability is the ability of a sediment to transmit water.  In other words, permeable materials allow water to easily pass through it and impermeable materials do not let the water move through them.

We’re going to test the permeability of sand and gravel to discover which one is more permeable.

First, we will make a hypothesis about which material water will travel through the fastest.  Frannie thinks water will travel through gravel more quickly than sand.

Now we’re going to take apart the syringe and fill up the inside with gravel.  We’ll measure out one ounce (oz) of water with a small measuring cup and pour the water into the syringe, careful to hold it over a cup so it doesn’t spill everywhere.  For extra fun, we can time it with a stopwatch and see how long the water takes to go through the gravel.

Water flows quickly through the empty syringe on the left, a little more slowly
through the gravel in the middle, and very slowly through the sand on the right.

Next, we’ll empty and dry the syringe before filling it with sand and, again, watching how long it takes 1 oz of water to move through it into our cup.  Does the water move faster or slower than the gravel?

Frannie has found that the water moves faster through the gravel than it does the sand which means that the gravel is more permeable. She was right!

Permeability and porosity are related.  Materials with more open space can hold more water.  More space also provides a quicker flow of water through the material. Materials that have a higher porosity also tend to have higher permeability.  Clays, however, have a very low permeability but are very porous which means they can hold a lot of water but they won’t release it very quickly.  Clay and harder materials that also can’t transmit water very quickly, like shale and granite, are called impermeable layers.

BLOG: BMPs - An Industry's Response

by William Bieck, Heritage Hills Golf Course

“When disagreement or conflict is imminent, it’s better to be proactive than reactive.” 

This is an often used statement that recognizes it is better to correct problems before they exacerbate into a more difficult dilemma. It is easy for Golf Course Superintendents in the turf industry to discuss, debate, and share stories of new regulatory policies and the difficulties and costs to achieve compliance. But, when we “speak to the choir” amongst ourselves, we are not communicating to those who really decide our fate. Superintendents and the golf industry do not legislate...the government does.

This fact alone should compel those dependent on the golf industry or other industry that is under heightened scrutiny to share their strategies and positive environmental stories to those outside their circle of influence. I have been a golf superintendent for over 42 years and consider myself a strong advocate for environmental stewardship. As an industry, I have seen the Golf Course Superintendent’s Association of America (GCSAA) support its members with unlimited access to educational resources pertaining to environmental protection, conservation, and research. The golf industry has responded very positively to water issues. Over the past several decades, turfgrasses have been developed that can tolerate drought or poor-quality water. Technology advancements in irrigation equipment have greatly improved irrigation efficiency and uniformity resulting in less water use. Still, even with all these efforts to protect and sustain our environment, the golf course industry is commonly perceived to be a significant source of pollution and bad for the environment. These comments are simply not true and this perception needs to change in order to improve golf’s image.

In response, the GCSAA is increasing their emphasis not only to educate its members to the importance of responsible and sustainable stewardship, but to also share golf’s positive environmental stories with everyone, including detractors. 

BMPs, Best Management Practices, are the adoption of science-based agronomic practices that support proactive environmental stewardship. BMPs are a tool that will demonstrate to legislators, regulators and consumers the environmental policies that will augment trust and credibility into our management programs. BMP programs help superintendents manage golf facilities in an efficient manner while providing quality playing surfaces and protecting the environment. They also enable the golf course facility to operate where regulatory pressures exist, and they offer the industry a significant platform for advocacy, education, recognition, and demonstration of professional land management.

GCSAA has also recently launched an aggressive initiative of offering a BMP Planning Guide and Template to its state chapters to help develop and customize fundamental BMPs according to each state’s needs and requirements. It is the goal of the GCSAA to establish BMPs in all 50 states by 2020, a lofty goal that illustrates a sincere commitment to environmental improvement.

BMPs will address the many facets of golf course management. They are the method or techniques found to be the most effective and practical means of achieving an objective, such as preventing water pollution or reducing pesticide usage. Topics will include wellhead protection, irrigation efficiency, wetland protection, nutrient management, pesticide management, and surface and groundwater monitoring, conservation and protection.

Why use BMPs as a format to persuade golf’s detractors, environmental activists, and policy makers?  BMPs are the shared language recognized by regulators, conservationists, engineers and others as a means to driving improvements. It is important to note that BMPs are recognized in federal and state TMDL (total maximum daily load) policy as a major component of water quality improvement plans.

By implementing these practices, each facility will demonstrate to state regulatory agencies that their management practices are science-based and environmentally sound. By allowing governmental regulatory and compliance agencies to be involved in drafting these BMPs the industry has encouraged an open dialogue leading to positive changes that can have a significant impact on TMDLs and other measurable components. The end result of a successful BMP will be a healthy golf facility and a management plan that supports environmental improvement.

BMPs are the response of the golf industry to achieve a greater legitimacy and credibility. Many facilities will implement BMP approaches not just in reaction to mandated regulations, but as a proactive environmental stewardship business policy, that is, the best operations strategy for sustainability of the environment and the golf business.

It’s Water-Wise Wednesdays with Frannie the Fish! {Awesome Aquifer Kit: Discover Porosity}

This week in Frannie’s exploration of the Awesome Aquifer Kit is all about discovering the key concept of porosity.

For this activity, you 'll need sand, gravel, a syringe, a small cup, water,
 and a towel.  Frannie predicts that gravel is more porous than sand.

Porosity, in hydrogeology, is the capacity of rock, sand, soil, or other sediments to hold water.  We can measure it through the ratio of the volume of empty space in a particular sentiment to the total volume of the sediment.

We’re going to test the porosity of gravel and sand to discover which one is more porous.

First, we’re going to find out the volume of an empty plastic cup by filling up our syringe to the 35 cubic centimeter (cc) line.  Dispense the water from the syringe into the cup until it’s full to the rim.  Subtract the amount of water left in the syringe from the starting amount of 35cc and record this value.  Frannie found that her cup holds 30 cc.

Empty and dry the cup and then fill it with dry gravel. Fill the syringe again with 35 cc and dispense that water into the cup with gravel.  Subtract the amount left in the syringe from the starting amount of 35cc and record this value.  Frannie found that the cup with gravel holds 17 cc of water.

Empty and dry your cup before filling it with sand. Next fill the syringe with 35 ccs and dispense that water into the cup.  Subtract the amount left in the syringe from the starting amount of 35cc and record this value.   Frannie’s cup with sand holds 12 cc of water.

Fannie discovered that the gravel is able to hold more water and is more porous than sand.

To find the porosity of each material, we first have to determine the volume of material in each cup.  The volume of the sand or gravel in the cup will be equal to the volume of the water the cup can hold when full.  So the volume of our gravel and sand is 30 cc.

Remember that porosity is just the ratio of empty space over sediment so our porosity for gravel is p=17 cc/35 cc = .48 = 48%

Our experimentally determined porosity for sand is p=12 cc/35 cc = .34 = 34%

Frannie was right! Gravel is more
porous than sand!
