In addition,there are 12 sewage treatment plants already installed within the MRBH and others are being designed and built.The DRENURBS Project (Environmental
Rehabilitation and Sanitation of Valleys and Natural Riverbeds of Belo Horizonte) is also being implemented.Its main goals are water course cleaning,sediment control,institutional reinforcement by Belo Horizonte City Hall,and integration of water resources with urban scenery.
An environmental monitoring program has begun for the Rio das Velhas as part of the Manuelz?o Project.Physical,chemical,and biological indicators are being used to:(1) determine the contribution of the Rio das Velhas to the condition of the Rio o Francisco;(2) identify point and diffuse pollution sources throughout the basin; (3) assess aquatic ecosystem health and environmental quality; and (4) monitor changes in water quality due to sanitation interventions and sewage treatment.The assessment and monitoring will employ modified monitoring designs and indices of biotic integrity used by the USEPA’s Environmental Monitoring and Assessment Program.
The objective of the Manuelz?o Project is to return the fishes to the Rio das Velhas.The project adopts the basin as a research,planning,and social mobilization
unit.The basin perspective helps to integrate nature,history,environment and social relationships,and human health.Our data,collected as part of this
project,contribute to the knowledge of freshwater biodiversity in the Rio das Velhas,which can be useful for Brazilian decision makers.We are using the Reference
Condition Approach (RCA,least disturbed sites)of Hughes (1995) and Bailey et al.(2004) for biological assessment in the Rio das Velhas basin.The RCA has a number of key features that make it useful for our purposes:(1) It defines and quantifies ecosystem health; (2) it incorporates variation among healthy ecosystems; and (3) it uses the deviation of a test site from Reference Condition to measure the effect of stressors on the ecosystem.We measure variability in benthos and fishes among sites in “Reference Condition”in four subbasins (Taquara?ú,Paraúna,Curimataí,and Itabirito).These reference subbasins are minimally exposed to human stressors such as effluent discharges or land uses that often disturb ecosystems.We plan to elaborate,test,and validate an empirical model to explain as much of the variability in the reference site biota as possible,based on the environmental characteristics of the sites.
