The stand- pipes for the sewer system were in place and capped. The well casing had a .sanitary seal and the electrical wires were in conduit. The distance between the well and the septic system was measured and fo.und to be 100 feet. A water sample was collected on December 6 and delivered to the Chem Lab. HENKINS SUBDIVISION . lO/9/85 Keith Bandt Platted: Zoned: Lot Description: P robl ems: Probable Causes: End Effect: September 13, 1955 (Plat #387) R6 in 1982. Previously, it was zoned. UNRESTRICTED 61 lots and 3 tracts. Majority of the lots are 20,000 s.f. One of the affected lots is only 14,365 s.f. Water table has increased in recent years causing systems to fail and sewage to leak onto the ground surface. Lots most affected are cross-hatched on Figure 1. Based on soil tests conducted in 1982 on several of these lots, water levels have increased 4-6 feet. System failure in this case can contaminate the shallow water table, and the potential exists for contaminating the deeper drinking water aquifers although no problems have surfaced to date. Due 1. e 0 to a combination of 3 factors; Natural phenomena - A natural increase in the water table due to changes in the hydrologic cycle. There is historic evidence that the area affected was very wet, saturated by ground water, prior to development. There are presently many indications of saturated soil as evidenced by small streams, springs, and weeps within the affected area. Monitoring well data helped establish the boundaries of the affected area. A stream diversion around lots 8,9, and 10 may be a factor in fixing the water table elevation on Lot 15, Block 3, although the degree of impact is difficult to assess and is not the sole factor. Wastewater loading from septic systems probably aggravates the situation by contributing to the water table rise. Lots 12-15, Block 3 and Lots 5-6, Block 4 will be required to abandon their existing systems and hook up to a holding tank or package treatment plant (innovative) by November 1, 1985. Lots 3-4, Block 4 will be required to raise the absorption field to meet the proper separation distance to ground water. Curtain drain systems are not viable and have been excluded as an option. High fecal coliform levels found in a monitoring well on Lot. 3, Block 5 are currently being, investigated. The water supply well for this lot is in close proximity and is only drilled to a depth of 44 feet with a static water level of 6 feet from the ground surface.
