Water Quality & Conservation

Water Quality & Conservation

A Finite Resource ●

70% of earth is covered in water ○

● ● ●

2.5% of the 70% is freshwater ■ 1% of the 2.5% is easily accessible (frozen), so only 0.007% of earth’s water is accessible freshwater

Distribution of clean water is extremely uneven due to geography, climate, and politics Issue on both macro and micro levels, between countries (ex: United States vs.

Libya) and within countries (ex: local water management between Indian villages) “By 2025, an estimated 1.8 billion people will live in areas plagued by water scarcity, with 2/3s of the world’s population living in water-stressed regions as a result of use, growth, and climate change.”

US Water Quality & Conservation – History ●

Riparian Doctrine: If someone owns land adjacent to a body of water, that person has the right to freely use that water. ○ ○

●

Prior Appropriation Doctrine: The first person to claim use of a body of water has priority rights. Those with priority rights can take as much water as they can use productively. ○ ○

● ● ●

Developed in the Eastern U.S. Assumes an abundance of water.

Developed in the Western U.S. Assumes a limited supply of water.

Both doctrines developed organically based on needs within the historical context.

Both doctrines are based on private ownership.

Neither doctrine encourages conservation or the protection of water quality.

US Water Quality & Conservation – Current Regime ●

State, Tribal, and Local Levels ○ ○ ○

●

Since water policy developed bottom up rather than top down, it varies from state to state and city to city.

Most state water policy is based on riparian rights, priority rights, or some combination of the two.

Some state policies also encourage conservation and protection of water quality, although these are often limited in favor of economic concerns.

Federal Level ○ ○ ○ ○

US Water Quality & Conservation – Regime Change ●

Vertical integration of federal, state, tribal, and local actors. ○

●

Proactive approach to water management ○

●

Federal policies like the Clean Water Act set nation-wide standards for water quality and demanded collaboration between the EPA and state actors to comply with those standards.

State allocation of water resources commonly occurs in instances of water shortage. More sustainable policy would limit the uses of water overall in order to reduce shortages.

Incentivise water conservation in agriculture, industrial, and municipal use. ○

Rather than compromise environmental health for economic growth, create legal conditions (regulations, subsidies) under which conservation is more lucrative than the alternative.

Desalination (aka Desalinization) ●

Removal of dissolved salt from seawater ○

○

● ● ●

Distillation/thermal desalination: Basically same as natural hydrologic cycle. Heat evaporates water, leaving behind salt; the water condenses at lower temperatures and can be collected. Very old method; used on ships. Desalination plants imitate and speed up the process through machines Reverse Osmosis: Salt water forced through a filter. The larger salt molecules are captured while the smaller water molecules penetrate through. More expensive

Decreases dependence on outside water resources; reliable Cost has halved in past 3 decades Mainly in Middles East, Australia, and California

Desalination Issues ●

High energy input required, high emissions; creates a positive feedback loop ○ ○

●

Extremely expensive ○

●

Requires large-scale facilities to supply large populations, research, transportation

Leftover brine and chemical pollution ○ ○ ○

●

Higher emissions leads to global warming, leading to salinization of water, drought, water shortages Consumes 14x the amount of energy it takes to conserve groundwater

High concentrations of bisulfates, coagulants, and chlorine dumped back into the water Salinizes the water even more, destroying balanced ecosystems 2 Gallons of salt water = 1 Gallon of post-desalination freshwater + 1 Gallon of very briney water

Machinery used to collect the water also unintentionally kills billions of fish each year, decreasing available catch and harming ecosystems

Solutions related to Desalination ●

Alternate disposal of brine ○ ○ ○

●

Use brine for food preservation and cooking Cooling metals De-icing roads

Combating energy use and price ○ ○ ○

Many of the desalination plants use a lot of electricity, from oil or coal, to push the water through a filter. Switching to renewable energy will help with cost and emissions.

Switching to a graphene nanopores filter would be cheaper to replace and easier for water to flow through while keeping out salt.

Keeping desalination on a smaller scale to reduce emission.

Desalination overall ● ● ●

Possibly good for small-scale projects; too many consequences on the large scale Not a viable solution to solving water quality and quantity problems Conservation better than desalination in the long-term economically, environmentally, and socially

Wetlands ● ● ● ●

Provide food and habitat for an array of plants and animals Serve as a buffer for flooding and storm surge ○ This is due to their sponge-like ability to absorb water Naturally improve water quality ○ Extensive root systems lock soil in place and filter pollutants from water Among the most biologically productive ecosystems in the world and their microbial activity enriches water and soil with nutrients

Wetlands Problem ● ● ●

Wetlands are disappearing at an alarming rate More than half of the wetlands in the contiguous United States have been lost due to agriculture and development These losses have caused many environmental problems such as ○ Water quality protection ○ Habitat loss for fish and other wildlife ○ Decrease in flood prevention

Solution ●

Conservation and restoration through action from government policy, government agencies and non government organization participation

Wetlands - NGOs ●

The United States - or rather what the United States is today - originally contained roughly 392 million acres of wetlands pre-Revolutionary War.

●

Today, largely due to the efforts of government and NGO participation, we have retained around 274 million acres of those wetlands.

However, many of these acres are new, created wetlands, rather than the original wetlands that once existed.

That being said, we are still losing wetland acreage at the rate of 6o acres an hour in the United States alone.

This does not include the mass wetland degradation that is taking place north of the border in Canada, which feeds into the rivers and waterways of the US as well as provides many natural services that we take for granted.

Ducks Unlimited Wetlands International Society of Wetland Scientist Delta Waterfowl Many more…

For this presentation, we will focus mostly on Ducks Unlimited, the actors included in the organization, and the progress made.

Wetlands - Ducks Unlimited ● ●

●

●

Ducks Unlimited was founded during one of the United States worst periods of drought, The Dust Bowl.

Originally, it was started by a small group of avid waterfowl hunters that recognized the droughts effects on waterfowl populations, which, at the time, were nearing a point beyond recovery.

Their mission was simply habitat conservation. There were no complex plans put in place; it was just to conserve and restore habitat in whatever means necessary.

In order to achieve this, Ducks Unlimited was established as a non-profit, operating solely on donations made by other hunters and conservationists.

Currentry, now in operation for more than 80 years, they are the largest and most effective wetland conservation organization in the United States, and arguably, the world.

This has been made possible through the partnerships with private individuals, landowners, agencies, government, and scientific communities.

As of January 1, 2019 Ducks Unlimited has conserved: ○ ○ ○ ○ ○

6,456,698 acres in Canada 1,965,760 acres in Mexico 6,055,915 acres in the United States 177,514,637 acres influenced (these are 10 year policy agreements) With a grand total of 191,993,009 acres collectively conserved and influenced.

â—?

Many of the Ducks Unlimited projects actually do not concern ducks at all, but rather establish or restore/conserve wetlands near cities in order to provide urban populations with clean drinking water. However, a happy coincidence of this is that it provides necessary habitat for many local and migrating species.

Currently, there are plans to expand from North America into South America in order to conserve and restore the Amazon as well as the many beneďŹ ts that it provides the locals, the world, and the many wild species that rely on it.

Wetlands - Ducks Unlimited Actors ●

Environmental Champions (originators and CEO of DU) ○

In essence, the originators, current CEO, and scientists of Ducks Unlimited are Environmental Champions ■ They work within the organization, identify problems that are personally important (duck populations and habitat loss), of which, they believed the organization could make a difference, using the sustainability value to attract members to donate and support the organization, and used their gathered knowledge to help incorporate private individuals, landowners, agencies, government, and scientific communities into the organization.

■ This is used as way to encourage community-based social marketing, as well as environmental stewardship ■ This includes Systems Thinking Competence, Interpersonal Relations Competence, Anticipatory Competence, Strategic Competence, Sustainability Competence, and Problem Solving Competence

■ This includes Sustainability Competence, Systems Thinking Competence, Anticipatory Competence, Normative Competence, Strategic Competence, Interpersonal Relations Competence, and Integrated Sustainability Research and Problem Solving Competence.

Water Transfer Projects and Dams ● ● ● ●

Redirects water from natural sources Causes loss of culturally significant land Reduces quality of water Damaging to surrounding ecosystems

● ● ●

Affects outflow of body of water Restrict migration patterns of local wildlife (specifically fish) Increased evaporation from stagnant water http://theboardman.org/dam-project/ https://www.internationalrivers.org/human-imp acts-of-dams

Dams - Loss of Water Quality Water Loss from Reservoirs

●

The restriction/redirection of the natural flow of water leads to: ○ ○ ○ ○

Trapping of nutrients, resulting in toxic algal blooms, which kill other life in the affected area Deepening of rivers and lowering of groundwater (affects wells and plants) Greater surface area of water, leading to increased loss of water through evaporation Increased salinization of water through evaporation

https://www.internationalrivers.org/r esources/how-dams-affect-water-su pply-1727

Dams - Flooding ●

●

●

When dams flood, the water begins to decompose surrounding plant life Decomposing plants leads to higher methane and CO2 emissions Flooding also damages local communities and infrastructure

Dams - CSO ● ● ● ●

CSO stands for combined sewage overflow.

Some cities, such as Philadelphia, are using inflatable dams in order to assist the storage, conveyance, and treatment of water.

These dams are part of the “Green Cities, Clean Waters” plan in Philadelphia and a step towards a green infrastructure.

The goal of the project is to clean up the rivers in the city by reshaping how they look for increased property value, create jobs and raise civic pride.

Solutions to the Dam problem ●

●

Adding fish ladders allow for fish migration upstream, while bypass systems allow for migration back downstream Only current solution to flooding, evaporation, and nutrient/sediment trapping at the moment is to tear down the dams, and perhaps invest the money (estimated $34 billion) that would have been allocated for upkeep back into other renewable energy sources https://damsafety.org/sites/default/files/Cost%20of%20Rehab%20Repor t-2016%20Update_0.pdf

Dams and Water Transfer Projects Overview ● ●

While dams provide a source of renewable energy, the negative consequences may outweigh the positive aspects to some Dams are overall harmful to water quality, not only for the wildlife that inhabit the affected body of water but also to the humans that live around the dams due to flooding, low-quality drinking water and lowered groundwater levels

CSO and Clean-up ● ● ●

Cleaning out waste from lakes is extremely expensive. Mexico City spends nearly $900,000 daily to pump sewage out of Lake Texcoco.

If not properly decontaminated, dams increases CSO downstream, creating more pollution in the water and making it undrinkable.

In developing countries and cities, the lack of clean water causes a form of monopoly on drinkable water. ○ ○

Private and non-profit actors have started constructing pipelines to help direct water from different sources to not easily reachable communities in 27 different countries.

Since 1990, 2.6 billion people have gained access to an “improved” drinking water source, one that is designed to protect against contamination.

Government is investing in better infrastructure (South Africa) Various non-profit groups test the water quality to detect if there's a presence of e.coli in water sources.

Desalination technology eventually becoming more affordable .

Monitored natural attenuation is being used as an alternative to pump-and-treat or other active technologies.

Reinjection of treated groundwater has also proved to be an effective treatment in superfund sites if certain conditions are met.
