Water for Human Use or for Respect?

This project aims to examine the influence of people and animals living near rivers on water quality. The composition of water and the presence of different species in rivers will be compared to Lake Erken. The results show that rivers in areas with human and animal activity have higher abiotic factors in water compared to the lake.

  1. Is water for human use or for respect? Jānis Burvis Natalia Biała

  2. Rivers are a water reservoir over the earth surface. • The water in the river is not stable but it flows usually from mountains, lakes or other sources to a sea. • In streams and rivers we can find a lot of different species of plants, algae and animals. INTRODUCTION

  3. The aim of our project is to find out if people and animals living near the rivers have any influence on the river water contents and quality. • We would like to examine composition of water and animals that live in the rivers and want to compare the results from rivers to Lake Erken.

  4. Map of chosen sites

  5. If the water flows from lake to the sea through rivers located in areaswhere people and animals live and where infrastructure is developed, then the abiotic factors (temperature, pH and total phosphorus) in river water are higher than the water in the Lake Erken. To examine how big influence our way of living has on the environment in streams. HYPOTHESES

  6. As the surrounding areas have a big effect on water quality in streams, the ASPT-index will decrease at each site, travelling from the outlet of Lake Erken towards the Baltic Sea. To check difference between the quality in lake water system (source) and rivers which flow from the lake.

  7. Due to the fact that water in pools is almost still the ASPT index and water quality will be lower than it is in flowing water – riffles. To check if pools can somehow keep good quality

  8. MATERIALS METHODS

  9. RESULTS Diagram 1. ASPT values in rivers The ASPT – values are rather higher in riffles than in pools.The highest ASPT value was noticed in site 2 and it was 7,5. The lowest noticed value was 2,5 in site 3.

  10. The pH values varied from 8,4 to 9,2. The highest values were measured in the fifth site where the measurement was 9,2. The lowest value (8,4) was noticed in site two (pool).The average pH value was 8,7. Diagram 2. pH values in different spots The lowest value of total phosphorus was noticed in site 1and it was 23-24. The highest results were noticed in site 4 (56) and site 2 (64). Diagram 3. Total phosphorus results in rivers

  11. If the water flows from lake to the sea through rivers located in areas where people and animals live and where infrastructure is developed, then the abiotic factors (temperature, pH, oxygen condition and total phosphorus) in river water are higher than the water in the Lake Erken. DISCUSSION Diagram 4. Compare of parameters between Lake Erken and streams

  12. The most common surrounding to investigated rivers was car roads or highways; in addition in neighbourhood of a few of them we found beach, farm and household. • Water was alkaline. pH value was same in Lake Erken and average value from rivers. • Temperature was getting higher every day. • Streams were more nutrient rich than Lake Erken

  13. If the water flows from lake to the sea through rivers located in areas where people and animals live and where infrastructure is developed, then the abiotic factors (temperature, pH, oxygen condition and total phosphorus) in river water are higher than the water in the Lake Erken. Trueandfalse Diagram 4. Compare of parameters between Lake Erken and streams

  14. As the surrounding areas have a big effect on water quality in streams, the ASPT-index will decrease at each site, travelling from the outlet of Lake Erken towards the Baltic Sea. Diagram 5. Compare of ASPT values between Lake Erken and streams

  15. Water quality in rivers are lover than in Lake Erken. • In some rivers water quality is higher than in Lake Erken. • One reason for this is that river faster changes its water.

  16. As the surrounding areas have a big effect on water quality in streams, the ASPT-index will decrease at each site, travelling from the outlet of Lake Erken towards the Baltic Sea. True Diagram 5. Compare of ASPT values between Lake Erken and streams

  17. Due to the fact that water in pools is almost still the ASPT index and water quality will be lower than it is in flowing water – riffles. Diagram 6. Compare of results between riffles and pools

  18. Average ASPT value in pools was higher than in riffles. • Water in pools is not exchanged so often as it is in riffles • This project should be continued and more factors should be examined to see what makes big difference between riffles and pools.

  19. Due to the fact that water in pools is almost still the ASPT index and water quality will be lower than it is in flowing water – riffles. FALSE Diagram 6. Compare of results between riffles and pools

  20. Is water for human use or for respect? CONCLUSION

  21. = 4 PROFITIAL USE? NO!!! 4 RESPECTFUL USE!!! =
