| Teaching & Learning Strategies: |
This module will be taught in one theory class of one hour duration for 12 weeks and one 3 hour practical per week for 10 weeks. To consolidate lectures and practicals, students will normally be required to carry out assignments and prepare a weekly practical report analysing their own research and results. Any course-related issue or questions that may arise will be discussed at lectures. |
| Module Aim: |
To introduce the student to the fundamentals of environmental science and environmental analysis |
| Learning Outcomes |
| On successful completion of this module the learner should be able to: |
| LO1 |
Describe the principles of environmental theory and practice. |
| LO2 |
Perform a representative range of physico-chemical analyses of water and waste, applicable to pollution and environmental assessment. |
| LO3 |
Demonstrate an understanding of and interpret Reports from EPA and other bodies |

The Environment
The four spheres of the environment, dynamic nature and interactions, natural cycles, pollution as an imbalance.The environment and health
|
|
The Lithosphere
Soil formation, generalised chemical composition of mineral (silicates/aluminates) and organic matter (humic/fulvic acids). Soil profiles and horizons, soil texture and ped structure, soil properties :pH, conductivity, cation exchange, nutrient cycling.
|
|
The Hydrosphere
The hydrological cycle. Water sheds/river basins. River and lake structure and zones, groundwater/aquifers, surface water quality (phosphates, nitrates, ammonia, organic matter, dissolved oxygen, BOD and COD), trophic status, eutrophication, pollution sources (point-source v diffuse). Representative sampling. EPA reports. Catchment management.
|
|
Water treatment
Unit processes in treatment of raw water to potable water. Alum coagulation and flocculation, Jar Tests, filtration, disinfection (chlorination/ozone/uv), fluoridation. Residuals. Parametric values, PV. EPA Compliance reports.
Waste water treatment (screenings/homogenation/aeration-activated sludge/trickle filters/anoxic-anaerobic, disinfection), Urban Waste Water Directive
|
|
The Atmosphere
Chemical composition, stratification, ozone, CFCs, greenhouse gases, particulate matter, acid rain, CAFE Directive, air quality monitoring.
|
|
The Biosphere
Biodiversity, invasive species, conservation, Birds/Habitat Directive (SPA, SAC)
|
|
The EPA
Establishment, structure, roles. licencing, IPPC.
|
|
Practical
Practicals will develop skills and compentences in soil and water/waste water analysis. Practicals to include Soil testing for pH, moisture, conductivity, nutrients, texture and organic matter (Walkey-Black method and LOI). Water analysis will include colour, turbidity, conductivity, chloride(Mohr). nitrate (uv method), phosphate (mrp), dissolved oxygen (Winkler), BOD and COD (Hach micro-digestion).
