Question
http://www.abcwua.org/Enviornmental_Impact.aspx
http://www.abcwua.org/education/el_WSD_2.html This is called Water System Diagram
What does the acronym ABCWUA refer to?
Please describe briefly what the San Juan-Chama Drinking Water Project is all about. Why was this whole thing created in the first place?
Some of the research even into the 1990s suggested that the so called “Great Lakes” (oftentimes promised by early developers to the city of Albuquerque to lure residents to move there), did not have anywhere near the quality or quantity of water earlier estimated.
Please describe what could happen to the water supply over time……
According to ABCWUA what is the primary reason for the (SJCDWP) San Juan Chama Drinking Water Project?
What does it give the City of Albuquerque protection for? Compare to the supply of our aquifer water?
What are the scientists doing to protect the endangered silvery minnow fish?
Please mention:
Diversion dam: What is unique about the diversion dam in terms of sediments and fishes?
Other conservation-related measures they are performing…
Why did ABCWUA recreate the old Bosque (riparian…riverside forest) after construction was complete?....environment page describes a little…
Using a percentage, approximately how much water does the City of Albuquerque get from this project? 50%
How much from the aquifer…beneath the city of Albuquerque & surrounding outskirts?
Do you think there might be concern that the Colorado River (does not flow through NM, and is river that San Juan drains into) which supplies water to 7 US states and Mexico might not be able to continue to supply all these areas with their water needs, increasing demands, growing cities? Most years the Colorado River never makes its way to the Gulf of California…Gulf of Baja any more due to current demand.
What sectors of the economy might be impacted by this potential lack of water?
When describing the steps in the water purification process, please fill in these questions
What purpose do the settling/sedimentation tanks have to do with the incoming water?
What about the ferric chloride tanks?
The flocculation and sediment facility (what does this step of the process accomplish)?
Ozone? Remember this is bad stuff at ground level, destroys chlorophyll, hurts lungs, but vital to our survival in the atmosphere…the O3 molecule is great at trapping solar radiation that we don’t really want hitting us.
Filter: Sand & Carbon. Why is granulated carbon used, too?
Has ABCWUA done the bare minimum or better regarding water quality with their treatment processes & steps involved? (the environmental page has some info…..might need to search a little)
Please describe in detail some of the environmental-type measures that have taken place?
Now looking at the Map embedded in the slideshow (slide # 11) and also here: There is also a short description on the ABCWUA website and in the slideshow)
Water System Diagram link http://www.abcwua.org/education/el_WSD_2.html & buttons # 1 & 2 are helpful, here….button # 3 as well. Nice larger view of map and can click on various components………
Please give a short, yet detailed route of how the water gets from the San Juan River to the City of Albuquerque, (flow on the map is predominantly from North to South, a little more west & East up North….top of map)Please mention/describe these main components & how they interact, what they are doing as part of the Project, how they are a unique feature, flow direction, etc:
San Juan River-
Rio Chama-
Heron Lake-
El Vado Lake-
Abiquiu Lake-
Rio Grande-
Cochiti Lake-
City of Albuquerque-
Related to # 12…on what side of the Continental Divide is the San Juan River, West (flow towards Pacific Ocean) or East (flow towards the Gulf of Mexico)?
Related to # 12…on what side of the Continental Divide is the Chama River, West (flow towards Pacific Ocean) or East (flow towards the Gulf of Mexico)?
What does this mean the engineers needed to do to in order to get San Juan River water to the Chama River, what about the Continental Divide standing in between, separating river flows from one another?
Approximately how many people does this engineering feat serve, how many use the San Juan Chama water?

6. The Rio Grande silvery minnow is a small herbivorous North american fish. In order to protect them the U.S Fish and Wildlife service has annouced to released the "RIO GRANDE SILVERY MONNOW RECOVERY PLAN ".the plan includes updated scientific information about the species and provides criteria and actions needed to be taken to protect them.
7. The diversion dam diverts the river water to irrigation crops.Although all the sidements cannot be removed at a time ,some of it can be removed which leaves the riverbed scoured and armored.the river , which now has no sediment ,has improved carrying capacity andwill pick up sediments from the streambed below the dam.As in everything else in nature , balanced will be achieved in one way or the other .
8. Also the fast-flowing water now became slow-moving water in the reservoir above the dam.This loss of energy caused the river's sediment to drop and settle behind the dam.
9. Dams are often built with FISH LADDERS TO ALLOW FISH PASSAGES.
10. After three years od drought, the river was full replinishing the parts of floodplain in New mexico.The river suffered through years of drought but later it connected with its floodplain forests, which a vital component .Bosque is a riverside cottonwood forest which extends 200 miles through new mexico.
11. Settling tank allows suspended water particles to settle as it flows slowly through the tank.there by it provides some degree of purity.
12. Ferric chloride is used in many industrial and sanitary wastewater treatment applications , due to its high-efficiency and sludge dewatering agent.Therefore it is used to clean water of particles.
13. Floccuation is a process where in colloids come out of susoensions in the form of floc eother spontaneouslyor due to the addtion of a clarifying agent . It is used in applications like water purification and sewage treatment .
12. Floccouation and sedimentation are processors used to make water safe to drink or to reuse water .
13. san juan river - WEST
CHAMA - WEST
