Abstract/Description or Keywords A compliance assessment of selected agricultural practices was completed in the Cloverdale
area between September and December 2004. The assessment was initiated in response to
water quality sampling programs that found elevated levels of E. coli in watercourses used to
irrigate ready to eat crops such as spinach and lettuce. A serious outbreak of gastrointestinal
illness, traced to the consumption of spinach grown in the Cloverdale area, occurred in 2001.
The objective of this compliance assessment was to evaluate the degree to which agricultural
practices, related to animal and manure management, complied with the Agricultural Waste
Control Regulation (AWCR). A total of 61 hobby and commercial farms (376 ha) were
assessed. The study area was grouped into two priority areas (PA1-2 and PA4) based on
elevated E. coli levels measured in previously obtained water samples. PA1-2 tended to
support animal based commodities while PA4 tended to support blueberries and vegetable
production.
This compliance assessment found results similar to those of previous studies in that hobby
farms tend to have greater levels of non-compliance relative to commercial farms. For the three
main AWCR categories (storage requirements, pollution prevention and composting) that were
evaluated, commercial and hobby farms had a 95% and 66% compliance rate, respectively.
Commercial and hobby farms were 94% and 58% compliant, respectively, in PA1-2, while
commercial and hobby farms were 100% and 93% compliant, respectively, in PA4. This
suggests that the hobby farms may be a significant source of the contamination measured in
PA1-2. It is suspected the greater degree of non-compliance amongst hobby farms is related to
fewer available resources and lack of awareness regarding statutory requirements and best
management practices.
Four sites where animals had unrestricted access to watercourses were identified as significant
point sources for E. coli. Shortly after the completion of the field work, one site was rehabilitated
by the City of Surrey with funding from the Salmon Habitat Restoration Program.
This compliance assessment makes the following recommendations:
• Remediation strategies for the remaining three sites where animals have uncontrolled
access to watercourses need to be developed. It is recommended that this be done
similar to site that has already been rehabilitated by the City of Surrey;
• The Ministry needs to approach landowners to resolve the remaining significant noncompliance
issues - typically uncovered manure piles adjacent to watercourses. Should
non-compliance continue, the Ministry will continue to implement its compliance and
enforcement policy and procedure;
• The Ministry should consider completing an aerial assessment of the whole study area in
early spring 2006 to assess manure application practices and to assess portions of the
study area that were not assessed during this study;
• The Ministry, in partnership with other stakeholders, should determine ways to engage
the hobby farmers to improve awareness, compliance levels and environmental quality.
Potential stakeholders could include Ministry of Agriculture and Lands, streamkeeper
groups and local governments. Activities could take the form of working with any hobby
farm associations that may exist, such as the Horse Council British Columbia, development of educational materials and Ministry presence at community, trade and
agricultural fairs;
• Further investigations into the source of the elevated E. coli levels measured in PA2b
are recommended. These could be completed by any one of the stakeholders. It is also
recommended that the Ministry continue to work with local governments to ensure that
the Liquid Waste Management Plan commitments to sewerage infrastructure upgrades
are met.
