At weekly or bi-weekly intervals samples of the water should be sent 

 to the nearest branch of the state health department for bacteriological 

 analysis with the request that the tests be interpreted in terms of safety 

 for drinking purposes. Local municipal or county health authorities may 

 also make such analyses. Con- 

 tainers and directions for col- 

 lecting and mailing the samples 

 can be obtained from any state 

 board of health or from local 

 health authorities. The disa- 

 greeable taste which is some- 

 times present in chlorinated 

 water may give rise to some 

 complaints. This taste can par- 

 tially be removed or wholly 

 eradicated by the use of a so- 

 lution of sodium thiosulfate in 

 quantities equal to one-half the 

 amount of calcium hypochlorite 

 applied. The sodium thiosul- 

 fate stops the action of the chlo- 

 rine and must not be added 

 until at least thirty minutes after 

 the introduction of the chlorine.

management of the park areas and the facilities therein. 



DISTRIBUTION OF THE WATER SUPPLY 



It is essential that the water after it is purified be so distributed that 

 the individual using the park either at a picnic ground or in a camp or at 

 any other facility provided will find it more convenient to use the pure 

 water than to satisfy his wants from a contaminated supply. Drinking 

 fountains, if a centralized water system is used, should be located at all 

 places where people are accustomed to congregate. These should be of the 

 automatic shut-off type to avoid wastage of water. Wherever an outside 

 faucet, or drinking fountain is installed steps should be taken to prevent
