(1) The parametric value refers to the residual monomer concentration in the water as calculated according to specifications of the maximum release from the corresponding polymer in contact with the water. This is controlled by product specification. | ||||
(2) Where possible, without compromising disinfection, a water undertaker (in relation to a supply of water for human consumption purposes) must strive for a lower value. | ||||
(3) See also regulation 8(5). | ||||
(4) See also regulation 5(3)(d). | ||||
(5) See the definition of “pesticides and related products” in regulation 2. | ||||
(6) The parametric value applies to each individual. “other pesticide” means a pesticide other than aldrin, dieldrin, heptachlor and heptachlor epoxide. | ||||
(7) “Pesticides: Total” means the sum of the concentrations of the individual pesticides detected and quantified in the monitoring process. | ||||
(8) The specified compounds are benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(ghi)perylene, indeno(1,2,3-cd)pyrene and the parametric value applies to the sum of the concentrations of the individual compounds detected and quantified in the monitoring process. | ||||
(9) The parametric value applies to the sum of the concentrations of the individual compounds detected and quantified in the monitoring process. | ||||
(10) The specified compounds are chloroform, bromoform, dibromochloromethane, bromodichloromethane and the parametric value applies to the sum of the concentrations of the individual compounds detected and quantified in the monitoring process. | ||||
