Total Dissolved Solids (TDS)

# data[].attributes.body
This site has the most urban influence. It is closest to the city of West Fargo, so the city is impacting the river. This site has fertilizer as a possible factor, and soil erosion from a construction zone. The total water discharge at this site was 277.6 cubic feet per second.

# data[].attributes.body
This site has sewage lagoon effluence as a factor. Soaps could be seen floating at the surface of the water. The total discharge at this site was 523.3 cubic feet per second.

Describe Site features HERE: 40th Ave is the spot where the Maple River meets the Sheyenne River. Horse pastures on both sides of the river and large agricultural areas are factors. The total discharge of this site is 632.7 cubic feet per second.

The graph shows us that the recorded TDS at site A was 1137.5 mg/L, site B had 1131.00 mg/L, and site C had 1131.00 mg/L.

1. Describe  what your data leads you to believe about water quality at EACH of the three sites.
Explain in words what your data on the table is showing us

According to "Healthy Water, Healthy People Testing Kit Manual", our river would rate as poor. The range for a poor river is 900-1200 mg/L. (Total Dissolved Solids 46). Our river had values of 1137.50 mg/L at Site A, 1131.00 mg/L at Site B, and 1131.00 mg/L at Site C. The high numbers for TDS are because of the turbidity of the water in the Sheyenne River. Because we have clay soil, a lot of soil is entering our river which increases our turbidity and TDS. Site A had a higher TDS because there is currently construction happening on 12th Ave and the soil from construction is entering the river. Site B and Site C were the same which shows us consistency in our river.  At Site B, the sewage lagoon is the factor that causes a high TDS. At Site C, the pastures with runoff is causing the high TDS.
2.  MAKE THREE Land use recommendations to improve the sites- at least one per site, discussing each site separately
Once construction is completed at Site A, TDS levels should decrease. At Site B, a bigger riparian zone could be added to catch more phosphates that are entering the river. At Site C, a buffer zone could be added between the pasture and the riparian zone to catch animal waste. The buffer zone will also catch run off from agricultural byproducts.

Answer the following in paragraph form:
1. Why is it important  for students to check the Sheyenne for water quality issues?
Because the Sheyenne River flows into the Red River and the Red River is used for various uses in many towns such as Fargo, Wahpeton, and Grand Forks. The water quality of the Sheyenne helps us predict the water quality of the Red River.
2. What test are you running and what equipment will you use?
We are running the Total Dissolved Solids, or TDS, test. We will need a Milwaukee Waterproof Dissolved Solids meter. The model we will use is the YS1 2015 proplus SONDE Water Sampler.
3. Why are we looking at three different sites?
We are looking at three different sites to determine the entire overall quality of the Sheyenne River. We get a better idea of the overall quality with the more sites we test. Plus, each site has different characteristics and we can get an idea of what is affecting the Sheyenne River. Each site has something new to offer to the Sheyenne River. For example Site A at 12th Avenue has the lowest discharge and is effected the most by the city of West Fargo. The other sites also have something new to offer to the river.
4. Why are your test results important for us to know about?
If people are using this watershed for human consumption, one wants less TDS so that it is easier to filter through. The more TDS, the more tax dollars it takes to treat the water. TDS is also electrical conductivity.  According to How Water Turns Bad, TDS and Turbidity are closely related. Increased TDS causes increased turbidity. TDS also affects aquatic life. Certain levels of TDS are required for organisms such as plankton who rely on osmosis. For drinking water, TDS can cause laxative effects. (Water Pollution 10). TDS correlates to many things that people should be aware about.
5. What should be  healthy readings for a river in our watershed for your particular parameter?
According to the article Total Dissolved Solids, "Most aquatic ecosystems involving mixed fish fauna can tolerate TDS levels of 1000 mg/L." This would be the healthy parameters for our watershed. Another article titled, "Healthy Water, Healthy People Testing Kit Manual", the ranges for ratings are as follows: less than 300 mg/L is excellent 300-600 mg/L is good, 600-900 mg/L is fair, 900-1200 mg/L is poor and greater than 1200 mg/L is unacceptable. (Healthy Water, Healthy People Testing Kit Manual 46)
