Remarks		A satisfactory Bath Water	A satisfactory Bath Water	A satisfactory Bath Water	Bacteriologlcally this is a satisfactory Bath Water, but the chcmical test for chlorine shows the chlorine content to be in excess of the amount advisable for bath waters	A satisfactory Bath Water	Although the bacteriological content is not high for a bath water, the presence of B. Coli in 10 c c. and Streptococci in 1 c c. would only allow of thi being clasped as "Fair"	A satisfactory Bath Water	A satisfactory Bath Water	A good Bath Water	A satisfactory Bath Water	A good Bath Water	This sample of water is quite satisfactory	A good Bath Water	A satisfactory Bath Water	A satisfactory Bath Water	A satisfactory Bath Water	A satisfactory Bath Water	A satisfactory Bath Water
