Six of those eight appear to have impacted groundwater near the surface of the soil. "The results from the study did not raise serious concerns of extensive environmental impacts of the concrete liquid manure storage systems," wrote Komex International Ltd. scientist Russ Pagulayan in the report. "The plumes that were identified appeared to be fairly limited in lateral extent. Ascertaining the full significance of the impact from the eight sites that appear to be impacting groundwater is beyond the scope of this project.". Ontario Pork publicly released the findings of the three-month study last Friday in Exeter. The study was done in 13 counties including Huron, Bruce and Lambton between October and December 1999. "I believe pork producers have demonstrated their commitment to the environment in a proactive and responsible manner...We were not surprised by the results of the study as it shows the vast majority of manure storages are doing. their job," said Ontario Pork director Dennis Zekveld who chaired the environmental committee which commissioned the study. The cost was divided between Ontario Pork and the CanAdapt program offered by Agriculture and Agri - Food Canada. PROTECT (Presenting Recommendations on Township Environmental Concerns Together) disputed the findings. Disappointed of being "denied access" to the draft and final reports ,after being asked to sit on the study committee, member Francis Hogan read from a statement that "Ontario Pork failed to deliver on its promise. PROTECT was asked to participate, agreed to participate and, unfortunately, was not allowed to fully participate. We regret this lack of ability to be fully involved." Zekveld said the committee included the Ministry of the Environment (MOE); Ministry of Agriculture, Food and Rural Affairs (OMAFRA) and the Ontario Federation of Agriculture for the purpose of reviewing tenders from firms interested in conducting the study. The project was awarded to Komex International Ltd. Zekveld admitted he excluded PROTECT because he felt the conduct of its representative "compromised the integrity of the report." While PROTECT will issue an official ~response to the study after March 20, Paul Frayne said eight of 50 farms is 16 per cent, a significant number of farms with manure storage problems. "We were promised 18 months ago these leaking sites are the exception," he said. One per cent of hog farms Pagulayan wrote in the 42 - page report that the 50 farms represent just one per cent of the 5,100 hog producers in southern Ontario. Of the 50 subject farms, one or two concrete manure storage tanks were new while 16 were more than 15 years old, said Pagulayan. They represented old and new barns with some storage under barns; others above ground. Soil conditions ranged from fine sand to silt clay and tight clay. Zekveld added later the oldest storage tank studied is over 30 years old and it was "fine". Don Mills, co-chair of ALERT (Agriculture Livestock Expansion Response Team), said,his group wonders why manure storage tanks are leaking when apparently small cracks in concrete are supposed to seal themselves. Komex studied the soil around the tanks and found signs of hog manure at eight sites. "We have to identify whether we're dealing with surface entry of manure from spills during loading...or pipe disconnect or overtop of the tank," . said OMAFRA's byproduct management engineer Don Hilbom. "With further study, if the tanks are identified to be leaking we'll review what's happening. Ontario Pork Dennis Z director ekveld "The other thing we've got to be dealing with is what is the magnitude of the cracks. Previous thinking is small stress cracks in concrete (seal) but are we dealing with Targe structural cracks? We haven't been out to see the sites. We don't know where the sites are." Hilborn added he's pleased to hear Ontario Pork is following up on the study. Zekveld said Ontario Pork is considering Komex' proposal to monitor the eight subject sites for two years. Because of confidentiality, Ontario Pork plans to work through Komex. Kathy McCarrell of CARES in Bruce County asked how many of the hog farms had more than 2,500 animals. Pagulayan said )he farms ranged from small to "a fevi" large farms, one with a barn more than 200 metres in length. He didn't know how many hogs were kept at each farm. Zekveld said he doesn't know either because the 50 were selected by Komex from a list of 100 (provided by Ontario Pork) and kept confidential to protect the farmers. The Huron County Farm Coalition was one of the groups to praise Ontario Pork for its study. "Ontario Pork has taken the initiative but it's very important to do the follow up work,' said chairman Ron Douglas. Afterward, agricultural specialist Murray Blackie from the Ministry of the Environrncnt told The Lakeshore Advance the study sheds more light on the state of concrete manure storage tanks in southwestern Ontario. The information will help the ministry develop methods to deal with aging tanks and how to repair them in the event of a spill. "We support the Ontario Pork study," said Blackie, adding if one in six tanks cause problems then a provincial strategy is needed. Hilborn of OMAFRA concurred that more study is needed to develop solutions. He said three areas need further study: handling of manure (are farmers spilling it when loading?); what are the problems in the structure of existing tanks and what new rules should be drawn for construction of new concrete tanks.
