Bakkavor has stopped using chlorine-based cleaning products at its Alresford Salads salad washing and packaging factory near Alresford.
This means that the chemicals used every night to clean the factory’s equipment will not be able to react to form chloramines which are highly toxic to water life even in extremely low concentrations. The EA and others stopped Bakkavor using chlorine in the daytime salad washing water some years ago.
This is one small victory in our campaign to stop Bakkavor’s salad washing factory at Alresford polluting the headwaters of the River Itchen SAC and SSSI - one of our finest and most highly protected chalkstreams.
However, two huge issues remain:
- The overnight cleaning products are still being discharged straight into the upper reaches of the Itchen rather than to the sewage system;
- Pesticides washed off the salad crops are also entering the river via an adjoining watercress bed with no monitoring for these potential lethal pesticides taking place.
The solution to the overnight wash is clear: under the precautionary principle, it must be tankered away or connected to the sewer (as Vitacress does at its nearby plant on the Bourne Rivulet). We find it incredible that industrial effluent should be discharged to any river. Bakkavor will howl about the cost but why should any business, let alone a multi-million pound one, be allowed to dump potentially toxic chemicals in the headwaters of a SAC river.
The pesticides could be an even bigger threat to the Itchen. We notified the EA formally last summer about our discovery of a potential pesticide impact below the discharge point from Alresford Salads and the discharge point from the watercress bed operated by The Watercress Company (TWC). The water used to wash the salads is pumped to this adjoining watercress bed, flows through the cress beds and then discharges into the river. TWC’s discharge permit has no pesticide monitoring conditions. Thus, it is possible this potentially lethal pesticide brew has been entering the Itchen without any monitoring.
After our intervention, the EA has been carrying out intensive pesticide monitoring of these discharges and is due to report soon. We await the results with interest. Whatever the outcome, it seems clear that pesticides washed off the salads should be monitored and, if present in harmful quantities, removed whatever the cost.
