D'Lo Water Park : Strong River

The higher the concentration of e coli, the higher the risk of humans getting sick from recreating in the river. The federal standard for E. coli is 235 colony forming units per 100mL. For a designated swimming area, e coli concentrations shouldn’t exceed this amount. The higher the level goes from here, the more swimming should be limited. At 235 cfu/100mL the EPA estimates approximately 36 in 1,000 people will contract an illness from contact with the water. Young people and people with compromised immune systems are more likely to become sick. When we say sick, we’re talking about “swimmer’s ear,” upset stomach, diarrhea, but also very serious illnesses from Salmonella, Shigella, Giardia and the like which can be transported in water.
