Quality of water in Ribeira Pontido

  1. 1. AquaProject/ProjetoAgua Water quality in Ribeira do Pontido, Póvoa de Lanhoso Using macroinvertebrates as bioindicators Involved students : 11A, 11C, 12A, 12B, P29 School year 2013 / 2014
  2. 2. AquaProject/ProjetoAgua Why is it so important a WATER study? • … without WATER there’s no life. • … FRESH WATER distribution on the planet is asymmetric. • … the humankind doesn’t always give the importance needed to this precious resource. • … to remember how essential european rules are for water preservation. –European Water Charter

  6. 6. AquaProject/ProjetoAgua Study objectives Objectives were defined related with… – Water quality assessment… • Get to know the water quality of Ribeira Pontido. • Use of macroinvertebrates as bioindicators. – Field and experimental work – Data processing – Discussion and dissemination of results
  7. 7. AquaProject/ProjetoAgua Study area characterization • Urban Park in Póvoa de Lanhoso center, crossed by the Ribeira do Pontido (hydrographic network of Rio Ave). • Vegetation: grass, bushes and small trees. • Maintenance: Town Hall. • It has equipment for sports practice.

  9. 9. AquaProject/ProjetoAgua Materials and methods… Field • 1 local sample • 2 samples (dez2013/mar2014) • Net to scrape the edges. • Contents dumped into trays. • The macroinvertebrates were placed bottles with water from the Ribeira. • Measurement of the pH and temperature with a water sensor.
  10. 10. AquaProject/ProjetoAgua Materials and methods … Lab • Observation of the macroinvertebrates with a magnifying glass. • Classification of the living beings based on a grid made by Porto University teachers. • Counting the macroinvertebrates observed and classified.

  22. 22. AquaProject/ProjetoAgua Discussion… Lab The water quality has changed : - Excelent in December - Reasonable in March Possible reasons are: - The amount of nutrients increased due to organic matter decomposition. - Sampling errors. - Classification difficulties.
  23. 23. AquaProject/ProjetoAgua Conclusions • In most water quality studies are used physico-chemical parameters. • If there are occasional disturbances in the water quality, these will affect the results and because of that, we can’t effectively characterize the quality of water. • This study attempts to show the importance of macroinvertebrates in the determination of water quality.
  24. 24. AquaProject/ProjetoAgua Conclusions • The macroinvertebrates life cycle duration , their needs for nutrients, oxygen, ... make it possible that the biological assessment allow the detection of pollutants, increased organic matter decomposition, ... • The water quality evaluation should consider the set of physical, chemical and biological parameters.
