Comparing Our Local Water: White Rock Creek and Lake Lavon Sample Essay

The intent of traveling into the field to carry on the H2O quality trials was to prove the different ways H2O could potentially be infected of polluted. The trials we ran helped find the sum of pollution and whether or non it is safe for the wildlife to populate in as a home ground. The trials we conducted were: temperature. turbidness. conduction. flow rate. pH. and GPS.

The location where we conducted the trials was White Rock Creek. It was in between tonss of trees and it was on a incline. The biotic factors located in the brook were moss. algae. trees. grass. Phoxinus phoxinuss. spiders. and toads. Some of the abiotic factors at the brook were the Sun. H2O. stones. and broken tree limbs. Due to the to White Rock Creek being on a downhill the beginning is chiefly East Fork Trinity. White Rock Creek’s location is at latitude of 33. 11503 and a longitude of -96. 60764. With it being about 0. 2 metres deep and is approximately 3 metres broad. The country around the creek gets it H2O from the East Fork Trinity watershed and has a terminal point of Lake Lavon.

Trials
The trials we ran were: conduction. temperature. turbidness. flow rate. pH. and GPS. The conduction trial measures the ability of a solution to carry on an electric current between two electrodes. and measures the concentration of ions. The first thing we did was set the scope to high. set the tip of the investigation into the sample of H2O to be tested. We gently swirled the investigation for 30 seconds and allow to LabQuest read it and recorded the consequences. The criterion for conduction was & lt ; 2200 µus/cm. The temperature trial measures the Thermistor’s opposition and converts it into the temperature. The first thing we did was set the tip of the investigation into the H2O. so swirled it around for 30 seconds while the LabQuest generated a temperature. Then we recorded it in our diaries. The criterion for the H2O was 0-33 grades Celsius. The turbidness trial measures cloud cover of the H2O. First. we filled the cuvette with some H2O from the brook. and so we lined up the two pointers and closed it. We pressed drama on the LabQuest and run for 30 seconds. Then recorded the consequences in our diaries. The criterion for turbidness is 0-42 NTU. which stands for Nephelometric Turbidity Unit.

The flow rate determines the size of the deposits that can be transported by the brook. Flow rate besides effects the temperature of the H2O. First. we submerged the impeller of the detector to 40 % of the deepness. Then we had to happen where the current was and maintain it in the current for 30 seconds. Next we recorded the consequences in our diaries. The criterion for the flow rate varies. The pH trial measures how sourness or basicity of the H2O. Low pH can impact membranes which can impact the ability of the fish’s’ gills to map. The stairss to prove pH are as follows: Fill a bottle with creek H2O. cap the bottle. set the pH investigation into the H2O. imperativeness drama on the LabQuest and run for 30 seconds. Record the consequences. The criterion for the pH degrees in the H2O are between 6. 1 and 8. 8. The GPS trial was run to cognize where information was collected and it allows for comparings. This trial was reasonably easy to run. First we connected the GPS detector to the LabQuest. Then. when the latitude and longitude co-ordinates were displayed. we recorded them in our diaries.

Analysis
The creek H2O is of good quality. From all the trials we ran. the creek H2O was within all the criterions. Not one clip was it out of the criterions. The temperature was 5. 9 grades off from being out of the criterion. The dissolved O was at the last figure of the criterion. The conduction was good within the criterion by 2088 µs/cm. The pH degree was under the criterion by 0. 47. The flow rate didn’t have a criterion. The turbidness was under the criterion by 25. 1 NTU.

If the temperature was excessively low or excessively high. the brook would non be able to back up life because it would stop dead or over heat the animate being and works life. If the dissolved O degrees were excessively low of excessively high the fish would decease because they would either hold excessively much or excessively small O. If the conduction was excessively high. if and when lightning work stoppages the H2O. all the life would be killed because the H2O would be excessively good of a music director. If the pH was excessively low. it becomes acid-like and will get down “eating away” at things. If the flow rate is excessively high. the fish will be invariably traveling and will ne’er be able to halt. If the flow rate is excessively low. things will be excessively idle and a hazard of higher taint. If the turbidness is excessively high. the H2O will acquire excessively nebulose to see through it. The pollutants in the brook can be oil. human waste. chemicals from landscaping. and carnal waste merely to call some.

Decision
The intent of the H2O quality field trip was to prove the H2O of White Rock Creek. We did merely that. We went over the trials we were traveling to run every bit good as the probe-ware we would be utilizing in front of clip. so we would be familiar with the equipment. When we were at the brook. we conducted the trials one by one. and after the trial we recorded it. Overall. the trip was productive because we accomplished the end we set out to make. All of the trials we conducted were within the criterions. which is a good thing. The consequences of the creek H2O are as follows: the temperature was 28. 1 °C. the dissolved O was 6 ppm. the conduction was 112 µs/cm. the pH was 8. 33. the flow rate was 0. 086. and the turbidness was 16. 9 NTU. The consequences of the fat-head Phoxinus phoxinuss trials are as follows: Day 1 – Lab H2O – pH was 8. 21 and the temperature was

22. 5 °C. The fish were at the underside of the H2O and had small to medium motion. Lake Lavon H2O – pH was 7. 65 and the temperature was 22. 4 °C. The fish were at the underside of the H2O and had medium motion. White Rock Creek H2O – pH was 8. 28 and the temperature was 22. 3 °C. The fish were at the underside of the H2O and made small spaz motions. Tap H2O – pH was 7. 74 and the temperature was 23. 8 °C. The fish were in the in-between and top of the H2O and made really small motion. Day 2 – Lab H2O – pH was 7. 69 and the temperature was 27. 8 °C. The fish were at the underside and the center of the H2O and made tonss of motion. Lake Lavon H2O – pH was 7. 58 and the temperature was 27. 8 °C. The fish were in the center of the H2O and made tonss of motion. White Rock Creek H2O – pH was 7. 59 and the temperature was 27. 8 °C. The fish were at the top and the underside of the H2O and made some motion. Tap H2O – pH was 8. 28 and the temperature was 27. 8 °C. The fish were in the center and the underside of the H2O and made no motion. Day 3 – Lab H2O – pH was 7. 33 and the temperature was 21. 6 °C.

The fish were at the underside of the H2O and made small motion. Lake Lavon H2O – pH was 7. 62 and the temperature was 21. 7 °C. The fish were in the center and underside of the H2O and had medium motion. White Rock Creek H2O – pH was 7. 15 and the temperature was 21. 6 °C. The fish were in the center and the underside of the H2O and made tonss of motion. Tap H2O – pH was 7. 69 and the temperature was 21. 7 °C. The fish made no motion. Day 4 – Lab H2O – pH was 7. 41 and the temperature was 22. 9 °C. The fish were at the underside of the H2O and made a batch of motion. Lake Lavon – pH was 7. 70 and the temperature was 22. 8 °C. The fish were in the center and underside of the H2O and made a batch of motion. White Rock Creek H2O – pH was 7. 36 and the temperature was 22. 7 °C. The fish were in the center of the H2O and made tonss of motion.

Tap H2O – pH was 7. 36 and the temperature was 22. 9 °C. The fish were at the underside and were dead. Day 5 – Lab H2O – pH was 7. 96 and the temperature was 21. 9 °C. One fish was traveling really easy and one was dead. Lake Lavon H2O – pH was 8. 10 and the temperature was 21. 7 °C. Both fish were dead. White Rock Creek H2O – pH was 7. 88 and the temperature was 21. 9 °C. One fish was dead and one was traveling somewhat fast. Tap H2O – pH was 8. 16 and the temperature was 21. 7 °C. Both the fish were dead. The factors that affect the wellness of the watercourse can depend where the watercourse is located. But in most instances oil. gasolene. human wastes. carnal wastes. and dead beings can impact the wellness of the watercourse. The pollutants in the watercourse affect the H2O in Lake Lavon because the watercourse normally flows straight into the lake. So. all of the pollutants found in the watercourse are transferred to the lake every bit good as still in the remainder of the watercourse. The pollutants from the watercourse are non the lone pollutants in the lake. The pollutants from the watercourse were added to the pollutants already found in the lake.
