2011 for more informati<strong>on</strong> <strong>on</strong> the locati<strong>on</strong>s <str<strong>on</strong>g>of</str<strong>on</strong>g> past producing mines in the study area). Insummary, the c<strong>on</strong>taminants that are typically associated with wastewater effluentdischarges and other activities c<strong>on</strong>ducted at mine sites include:• C<strong>on</strong>venti<strong>on</strong>al variables (i.e., alkalinity, c<strong>on</strong>ductivity, hardness, pH, and TSS);• Microbiological variables (i.e., faecal coliforms and enterococci);• Major i<strong>on</strong>s (potassium, sodium, and sulphate);• Nutrients (i.e., nitrate, nitrite, amm<strong>on</strong>ia, and phosphorus);• Metals (aluminum, arsenic, bor<strong>on</strong>, barium, cadmium, copper, copper,chromium, ir<strong>on</strong>, lead, mercury, manganese, molybdenum, nickel, antim<strong>on</strong>y,selenium, str<strong>on</strong>tium, silver, and zinc);• Cyanides (str<strong>on</strong>g acid dissociable and weak acid dissociable);• Petroleum hydrocarb<strong>on</strong>s (oil and grease, alkanes, diesel-range organics);• M<strong>on</strong>oaromatic hydrocarb<strong>on</strong>s (i.e., benzene, toluene, ethylbenzene, and xylene);and,• Polycyclic aromatic hydrocarb<strong>on</strong>s (i.e., parent PAHs, alkylated PAHs, totalPAHs).3.1.1.7 Oil and Gas DevelopmentsBased <strong>on</strong> the informati<strong>on</strong> available, there is no active oil or gas producti<strong>on</strong> in the <strong>Fraser</strong><strong>River</strong> Basin (Hannigan et al. 1998). However, explorati<strong>on</strong> activities have revealedsignificant oil and gas potential in the Nechako Basin, the Quesnel trough, and the GeorgiaBasin (Hannigan et al. 1998).There are several important oil and gas pipelines that are being operated within the studyarea (Figure 3.7; Table 3.8). First, Duke Energy operates a pipeline that transports naturalgas from the Fort St. John area to various distributi<strong>on</strong> points within the basin. KinderMorgan Inc. and Pacific Northern Gas Ltd. operate pipelines that transport natural gas toend users throughout porti<strong>on</strong>s <str<strong>on</strong>g>of</str<strong>on</strong>g> the watershed and destinati<strong>on</strong>s located outside the <strong>Fraser</strong><strong>River</strong> Basin. In additi<strong>on</strong>, Kinder Morgan Inc. and Pembina Pipeline Corp. operatepipelines that transport oil from Alberta and Fort St. John to a refinery located in thelower mainland area. The gas plants, transmissi<strong>on</strong> facilities, and delivery points located inthe study area are listed in Table 3.9 and shown in Figure 3.7. Aband<strong>on</strong>ed and cancelledwell heads located within the watershed are listed in Table 3.10.22
