Crypto in the Water ?

May 20, 2017

“Crypto is the most common cause of diarrheal illness and outbreaks linked to water play because it is not easily killed by chlorine and can survive up to 10 days in properly treated water,” the CDC added.

“Swallowing just a mouthful of water contaminated with Crypto can make otherwise healthy people sick for up to three weeks with watery diarrhea, stomach cramps, nausea, or vomiting, and can lead to dehydration.”


Even proper chlorination of pools doesn’t kill the persistent parasite. It takes an especially large dose of chlorine to eliminate it.



The Clinton River and Lake St Clair , BOTH have issues with Combined Sewer Overflows after heavy rainfalls in SouthEast Michigan.  Might want to tape your mouth shut while kayaking, splashing, cooling off – when that sun comes out – and water recreation starts.

Cryptosporidium is spread with human feces in the water.

Emergency room visits for gastrointestinal distress increase after a heavy rain. These illnesses are believed to spike after a storm because rainwater mixes with feces in Combined Sewer Overflows into local lakes and rivers used for recreation and drinking water.

Retention basins like Kuhn (12TownsDrain) rely on sodium hypochlorite
(formula NaClO) aka bleach to disinfect the massive amount of water that enters into them. Cities and municipalities pay roughly $1.00 per gallon to bulk bleach suppliers thru multi-year contracts.

Chlorine KILLS items in the water, so heavy doses means NOTHING lives in the 50 or so miles of Open Channel Stormwater drains existing in Macomb County.  Chlorine kills the aquatic plants and animals, so no fish, no frogs, no plants, no water fowl, ducks, geese, etc., etc., etc.

Road salt is NaCl , right  ? We all learned that in grade school, middle school, high school. Chloride concentration (as low as 250 mg/L) or approximately
the equivalent of one teaspoon of salt in five gallons of water
have been shown to be harmful to aquatic life.
It creates a decrease in the biodiversity found among wetland areas,
altering the development of wood frogs,
decreasing the number and types of fish available,
and increasing mortality rates of aquatic organisms.

Residual chlorine in effluent (discharge) from a Retention Basin or WWTP can be harmful or fatal to aquatic species, and ideally, effluent should contain little to no chlorine at all.
