>… the NJDEP permitted level of chlorine currently being used at
Graydon Pool, .1 ppm, will not control bacteria. That is, the amount of
chlorine permitted by law in natural bottom swimming ponds will not
disinfect contaminated water.
Chlorine concentrations in the .1 ppm range will only control algae.
Typically, levels of 1 ppm to 4 ppm are necessary for disinfection purposes.
At Graydon, one-tenth of the amount necessary for disinfection purposes is
routinely being deployed (in accordance with established regulations).
So the nagging question remains, do you think the water at Graydon is safe
for swimming? Has the time come to shut down Graydon and build an all
season cement bottom pool?
