The bioavailability of a pollutant depends upon biological process such as diffusion, desorption and dissolution. A reduced bioavailability of pollutants in the soil can be as a result of slow mass transferal to the biodegrading microorganisms.Bioactivity and biochemistry are other vital challenges that have an effect on bioremediation. Bioactivity is a term used to show the operational state of bacteriological or micro organic processes. According to Lapworth et al., improving bioactivity increases the process of biodegradation (2012, p. For instance, when bioremediation is set to meet a specified minimum rate, one can adjust the prevailing conditions in order to alter the biodegradation rate which will in turn configure and control bioremediation. Naturally, the capacity of microorganisms to transfer pollutants to molecules, regardless of their simplicity or complexity, is relatively unlikely. This challenge can be overseen through various biochemical activities which can be controlled in an in situ operation in which one can regulate and improve the conditions in order to achieve optimal results.Select one of the emerging contaminants listed in Lapworth et al. as a topic for the rest of the assignment (be sure it is not something we talked about in class). Describe specific tests, experiments, and approaches a team of scientists/engineers could use to determine whether this compound could be removed from groundwater by bioremediation (in situ or ex situ).One of the emerging contaminants highlighted by Lapworth et al. 2012 is veterinary antibiotics. The ever increasing human population has forced milk and meat industry to skyrocket. This rise has caused a sharp increase in use of veterinary antibiotics as animal products industry seek to achieve the highly needed efficiency and profits (Gurpreet, & Jagdev, 2011). However, it is unfortunate that veterinary antibiotics have become an important cause of ground water pollution especially considering that most animal farming occurs in highlands where water catchment is prominent. Veterinary products are likely to be recycled within water systems because ground water in high altitude areas where farming comprises a significant amount of water tapped for human consumption.One of the best approaches a group of scientists could use to determine the amount of veterinary antibiotics in ground water is use of ‘polar organic chemical integrative sampler’
