- ItemUpper Thames River livestock manure and waste management program(Ontario Ministry of the Environment, ) Merkley, CraigAn overview of the 1987 UTRCA manure and waste management work program. A significant portion of the 1987 work program involved the promotion of corrective measures on livestock operations in the Upper Thames watershed. Staff worked closely with the local Beaches Strategy Program on this project. A total of 850 livestock operations were approached during the year. These farms had either been targeted from previous survey work (Hayman and Merkley, 1986) or were dairy operations. Appendix 3 includes "Kintore Creek watershed study - 1987 progress report" (March 1998).
- ItemContamination from private septic systems: 1989 and 1990 survey results(Ontario Ministry of the Environment, ) Poel, Karen; Upper Thames River Conservation AuthorityIn 1989 and 1990 a septic system survey was conducted in four areas of Oxford County. Results show that approximately one quarter of the surveyed residences in Hickson, Embro, Thamesford, and Beachville areas do not dispose of their grey water through a septic system. Older systems showed a greater tendency to have improper grey water disposal methods. Many drinking water samples analyzed contained bacterial contamination.
- ItemUpper Thames River livestock manure and waste management program 1985 - 1986(Ontario Ministry of the Environment, ) Hayman, D.; Merkley, C.In the late seventies, Pittock Reservoir began to experience annual beach closures for variable lengths of time each summer, either due to fecal contamination or blue green algae blooms in the nearshore waters. Studies of the Pittock Reservoir watershed found that many factors affect the reservoir water quality. Agriculture is one of the significant contributing sources of downstream water quality problems and has received little attention in the past. Hence the U.T.R.C.A. and M.O.E. initiated studies to assess the potential impacts of agriculture. Over 25% of the identified livestock operations in the reservoir watershed exhibited a potential to pollute nearby watercourses as a result of existing manure and waste management practices (U.T.R.C.A. and M.O.E. 1984). Further follow-up investigations in a smaller sub-basin of the Pittock watershed (Glasman and Hawkins 1985) and the Avon River upper basin (Hayman 1985) identifies livestock access, milkhouse wash water discharges and overland runoff to be the other factors attributing to poor rural water quality. These findings prompted the U.T.R.C.A., in cooperation with M.O.E., Southwestern Region, to document the pollution potential of all livestock operations upstream of Fanshawe and Wildwood Reservoirs which also began to experience beach postings due to public health concerns. Of the more than 2080 livestock operations identified, 324 were considered to have a potential to pollute from manure storage runoff, feedlot runoff and/or livestock access. An additional 523 dairy operations were located which have a potential to pollute via milkhouse wash water discharge to the open water (Appendix A).
- ItemThe effects of livestock manure application methods on water quality, focusing on nitrogen and bacteria transport in soil: Final report(Ontario Ministry of the Environment, ) Upper Thames River Conservation AuthorityIn a joint effort between Agriculture and Agri-Food Canada, the Upper Thames River Conservation Authority and the Ontario Ministry of Agriculture Food and Rural Affairs, this study was conducted with the following objectives: 1) To evaluate several manure management application techniques used in conservation management systems to determine the best method to minimize downward movement of nutrient and bacteria to tile drains under three different soil types; 2) To compare fuel consumption requirements of manure management application techniques and recommend practices with field scale testing; 3) Conduct detailed crop monitoring to determine the effects of the manure application methods on crop growth and yield.
- ItemAgriculture waste management program: 1992/93 final report(Ontario Ministry of the Environment and Energy, ) Poel, Karen; Upper Thames River Conservation AuthorityThe objectives of this study were: 1) Initiate a study/demonstration project to set-up and monitor a wetland treatment system for manure runoff from a solid manure storage system. 2) During winter conditions determine the effect of freezing temperatures on nutrients and bacteria in field spread manure. 3) Provide assistance on a study in cooperation with Agriculture Canada to monitor the effect of liquid manure application and management on surface and tile water quality from conservation tillage systems. 4) Continue to monitor water quality in the Timms Creek sub-watershed to evaluate the effect of restricting cattle from the creek at the three access sites. Investigate and promote the remediation of failing septic systems in the Timms Creek watershed. 5) Continue to monitor background and runoff event conditions of the Kintore Creek east and west sub-basins.
