leakage
And
spills
BAGHDAD UNIVERSITY
SANITARY ENGINEERING DEPARTMENT
M.SC. STUDENT : MARWA MOHAMMED
• Groundwater can be polluted / contaminated
as a result of HUMAN activity and Natural
conditions.
• Contaminations found in the groundwater cover
a broad range of physical, chemical (Organic
& Inorganic), bacteriological and radioactive
parameters.
WHAT IS GROUND
WATER POLLUTION ?
sourcesandcauses
Sewer leakage
 Sources: Poorworkmanship, defective sewer pipe,
breakage by tree roots, ruptures from heavy loads,
earthquakes, loss of foundation support etc.
 Results: Introduce high concentrations of BOD,COD,
nitrate, organic chemicals, bacteria and heavy metals
into groundwater
1 . Municipal
Liquid wastes
 Sources: Industrial waste water discharged into pits, ponds, lagoons
etc.
 Results:Introduction of hazardous and toxic industrial wastes
into the groundwater
2.- Industrial
Oil-field brines
 Sources:-
 Substantial discharges of wastewater in the form of brine
 Constituents of brine include sodium, calcium, ammonia, boron,
chloride, trace metals and high total dissolved solids
 Results:Groundwater become saline
Spills and Surface Discharges
 Causal activities includes leaks from pipes and
valves, uncontrolled waste disposal, intermittent
dumping of fluids on ground, flushing hazardous
and flammable liquids into water etc.
 Washing aircraft with solvents and spills of fuel at
airports can form a layer of hydrocarbons floating on
the water table.
Basics of spillresponse
Potential Pollutants
Oils
Chemical
Food stuffs
Sewage
Source – e.g. Oil
Storage
Pathway – e.g. a
Drain
Receptor – e.g.
controlled waters,
groundwater
sewage treatment
plant.
Oil spills associated with underground pipelines and tanks
can release benzene and other soluble petroleum
hydrocarbons that rapidly percolate down into the aquifer.
Negative Impacts of a Spill
• Endanger human health (Both Staff and Public)
• Damage The Ground Water
• Damage the environment
• Bad public image
• Damage property
• Heavy fines from the regulators
• Disrupt site operations
• Impact profits
Pressure
Soil movement
Pipe condition
Poor quality materialsand workmanship
Soil characteristics
Traffic loading
Leakage control method
Factor affecting leakage
Leakage and spill

Editor's Notes

  1. تسرب المجاري المصادر: صنعة ضعيفة ، أنابيب الصرف الصحي المعيبة ، تكسير جذور الشجرة ، تمزق من الأحمال الثقيلة ، الزلازل ، فقدان الدعم الأساسي ، إلخ. النتائج: إدخال تركيزات عالية من BOD ، COD ، نترات ، مواد كيميائية عضوية ، بكتيريا ومعادن ثقيلة في المياه الجوفية
  2. النفايات السائلة المصادر: مياه الصرف الصناعية تصب في الحفر ، البرك ، البحيرات وغيرها. النتائج: إدخال النفايات الصناعية الخطرة والسامة في المياه الجوفية ---------------------------- محاليل حقول النفط مصادر: - تصريفات كبيرة من مياه الصرف الصحي في شكل محلول ملحي تشمل مكونات المحاليل الملحية الصوديوم والكالسيوم والأمونيا والبورون والكلوريد والمعادن النزرة ومجموع المواد الصلبة الذائبة الكلية النتائج: المياه الجوفية تصبح مالحة
  3. الانسكابات وعمليات التصريف السطحية وتشمل الأنشطة السببية التسرب من الأنابيب والصمامات ، والتخلص من النفايات غير المسيطر عليها ، وإلقاء النفايات المتقطعة على الأرض ، وغسل السوائل الخطرة والقابلة للاشتعال في المياه وما إلى ذلك. يمكن أن تشكل طائرات الغسيل التي تحتوي على مذيبات وانسكابات وقود في المطارات طبقة من الهيدروكربونات تطفو على سطح الماء.
