Bacteriological contamination in the karstic aquifer of Yucatán, Mexico
Geofísica Internacional, 2000 El acuífero kárstico de Yucatán es al mismo tiempo la única fuente de agua para abastecimiento y receptor de las aguas de desecho. El uso y consumo de esta agua sin algún tratamiento ocasiona en los habitantes algunos problemas de salud como son la ...

Release of Sediment-Bound Fecal Coliforms by Dredging [PDF]
Applied Microbiology, 1975 Fecal coliform concentrations increased significantly (F test) in the immediate vicinity of a maintenance dredging operation in the Mississippi River navigation channel. Increased counts were attributed to the disturbance and relocation of bottom sediments by dredging and a concomitant release of sediment-bound fecal coliforms.

Fecal coliform disappearance in a river impoundment [PDF]
Water Research, 1983 Fecal colitbrm (FC) disappearance studies were conducted in Ford Lake during the summer of 1979. Ford Lake, an artificial impoundment at the lower end of the Huron River drainage basin belov, ~ Ypsilanti, Michigan, receives all upstream flow (2072 km: of drainage).

Surface Contamination of Beef Carcasses by Fecal Coliforms
Journal of Food Protection, 1991 A total of 18 half-carcasses was selected at random in each of three different meat processing establishments. Samples were taken by excision at seven sites on each half-carcass at the end of four processing sectors, from the dressing of the carcass to the packaging of boneless beef, and the fecal coliform counts per cm2 were subsequently determined.

Survival of Fecal Coliforms in Frozen Vegetable Homogenates
Journal of Food Protection, 1982 The resistance to freezing of fecal coliforms isolated from frozen vegetables was compared to that of Escherichia coli isolated from fecal sources. The objective was to see if lower resistance to freezing might explain frozen vegetable samples that contain fecal coliforms but not E. coli .

Survival of fecal coliforms and fecal streptococci in storm drain sediment [PDF]
Water Research, 1991 Abstract This study defined major factors influencing the survival of the bacterial indicators, fecal coliforms (FC) and fecal streptococci (FS), in separate storm drain sediments during dry weather periods. FC and FS abilities to survive were determined by field sampling and experimental treatments of laboratory stream models.
