Notes: 1. Pesticides” means: organic insecticides, organic herbicides, organic fungicides, organic nematocides, organic acaricides, organic algicides, organic rodenticides, organic slimicides, and related products (inter alia, growth regulators) and their relevant metabolites, degradation and reaction products. Only those pesticides which are likely to be present in a given water need to be monitored. 2. The maximum concentration applies to each individual pesticide. In the case of aldrin, dieldrin, heptaclor and heptachlor epoxide the maximum concentration is 0.030 μg/l. 3. The maximum concentration for “total substances” refers to the sum of the concentrations of all individual pesticides detected and quantified in the monitoring procedure. 4. The specified compounds are benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(ghi)perylene, indeno(1.2,3 cd) pyrene.
1.	Arsenic	μg As/l	10

9.	Lead	μg Pb/l	10
10.	Pesticides and related products:
	– individual substances	μg/l	0.10 (notes 1 and 2)
	– total substances	μg/l	0.50 (notes 1 and 3)

Item	Parameters	Units of Measurement	Maximum Concentration
Notes: 1. The total viable colony count should be measured within 12 hours of bottling, with the sample water being kept at a constant temperature during that 12 hour period. Any increase in the total viable colony count of the water between 12 hours after bottling and the time of sale should not be greater than that normally expected. 2. In 72 hours on agar-agar or an agar-gelatine mixture. 3. In 24 hours on agar-agar.
