Transport of microsporidium Encephalitozoon intestinales spores in sandy porous media

Towards a rational strategy for monitoring of microbiological quality of ambient waters

“…Oocysts (John et al, 2005). On the other hand, the size suggests that they transport in sandy porous media governed by colloid-transport processes (Brusseau et al, 2005). …”

Phytolith transport in sandy sediment: Experiments and modeling

“…The straining coefficient was estimated using an empirical relationship established by Bradford et al (2003): where d (cm) is the mean diameter of colloids/particles. It has often been assumed that particle dispersivity is equal to the dispersivity of a conservative tracer like Br − (Brusseau et al, 2005;Cortis et al, 2006). However, direct measurements of particle dispersion show that particle dispersivity decreases with increase in particle size (Auset and Keller, 2004).…”

Wastewater Reuse for Irrigation — Practices, Safe Reuse and Perspectives

“…For example bacteriophages (viruses) are resistant in the environment, have been shown to have the capacity to penetrate and reach confined aquifers, and have low infective doses [7]. Cysts of Giardia lamblia can survive and remain active for months or even years, are resistant to chlorination, have a low infective dose and can have serious consequences for vulnerable individuals [18]. Helminth eggs also survive for long periods of time in the environment, have a low infective dose and their incidence in Mexico is very high [19].…”
