Risk management - Assignment Example

Risk Management Insert Insert To set up the given problem on the contaminated running ground water can be controlled by some transport features on soil rock. The hydraulic movement explains the movement of water with the chemical that is defined by the retardation factor. It is because of the interactions of different chemical species on the soil surface. As a result, it retards the movement of chemicals on water by delaying their reach time on the downstream with the help of hydrologic and awareness of chemical structure to be identified.

Experiments are given to set the above problem whereby the retardation factors can be established by experiment flow in that for a given species ratio, it indicates the contaminant velocity. This explains the movement of chemicals in water. The Batch test is used to measure the coefficient distribution whereas soil is given in the solution sections. The procedure shows that it needs to be shaken for a time of 24-48 hours so that the amount absorbed in the soil can be identified. The different factors affecting the content include the following; salinity, organic content, chemical concentration on species and finally the pH with redox potential (Briand, 2010).

According to the given scenario, saltwater encroachment of aquifers, because of anthropogenic contaminants changes the quality of water with its ecological water status as in the wells. Additionally, chemical pathogens with discoloration like calcium, sodium, iron and manganese are present. Water in most of the wells changes the color, the taste or even the odor because of chemical spills on the ground. Nevertheless, a high level of chloride can be witnessed on wells and contaminated water (Briand, 2010).

It shows itself at the surface of the water wells with numerous numbers of the bacteria inside.To estimate the daily dose for 69 kg adult ingesting 2L/day contaminated water, Exposure dose (mg/day) =contaminant concentration (mg/L) * intake rate of water contamination (L/day) * exposure factor /body weight (kg) To calculate this, we assume the age and exposure that result in a 1 milligrams per day from the estimated figure.Cancer risk standard calculation Risk level =cancer potency factor*water concentration *(water ingestion rate/body wt)Where; Cancer potency factor is regarded to be 0.

045/mg-kg-dWater concentration=0.005 mg/LWater ingestion rate=2 liters/day (assumption of adult drinking rate)Body weight=69 kg (default adult weight) with 70 years default adult ageRisk level=0.55/mg-kg-d *0.0045 mg/L* 2 L/day *1/69 kg=6E-09.The side effects to the infants drinking the contaminated water can experience diarrheal illness from the contaminated water, disorders in respiratory, frequent vomiting, parasitemia diseases, and coma. In addition, the children can acquire various infections from the contaminated soil grounds like cutaneous, hookworms and ascariasis.

Infants should be highly protected from the above problems. ReferencesBriand, A. (2010). Reverse onus: An effective and efficient risk management strategy for chemical regulation. Canadian Public Administration, 53(4), 489-508. doi:10.1111/j.1754-7121.2010.00146.x
