Orthophosphate temperature conductivity level Water Lab Report

When it came to the Water quality, there are many factors that influence. Those include the conductivity level, orthophosphate, temperature, PH etc… In this lab, we first had to acquire the inquiries in regards to water quality by testing the samples levels of PH, Orthophosphate, and conductivity for seven samples that are coming from different water regions that varied from Rock Creek water to Anacostia River.

Orthophosphate is an important nutrient for plant growth and it is necessary for anti-corrosion. While PH measures the acidity of the water, conductivity is an important characteristic to measure the conduction level of those water samples to electricity. In groups of five, the tests were conducted at the testing stations that measured PH level, conductivity and orthophosphate level, and the information of oxygen level.

The following table summarizes the results that were obtained in the testing stations:

Sample Name pH Orthophosphate Conductivity
Rock Creek1 8.14 0.2 1,083
Little Falls 8.82 -0.1 1,130
Rock Creek2 7.43 -0.4 1,170
Lanham, MD 7.17 1.4 1,992
Tap Water 7.59 0.1 350
Anacostia River 7.25 -0.8 1,333
Tuckerman 7.34 1.3 2,057


Comparing the testing results we notice that the water sample that came from Lanham had the lowest PH level which indicated that it had the highest level of acidity which may have occurred due to lack of sediments in that region. The highest pH level was for Massachusetts avenue which could relate carbon dioxide dissolution in the water which made the water more basic than acidic. In terms of conductivity, the least conductive water was the tap water which could be due to the minerals dissolved in it. On the other hand, the highest conductive sample was the Tuckerman’s which has large amounts of solids and minerals salts dissolved in it. Comparing orthophosphate levels, we notice that the lowest is present Anacostia river and the highest is present in Lanham MD which is related possible to the soil structure and in return, the phosphorous metals present in this water.

The experiment was very informing, and it was very interesting to learn about the different aspects that could be tested in water. The different results in each test convey the level of corrosion, conductivity, and other features of those water samples that we can find in our regions.
