Provided technical expertise on a case in which a tenant in a mobile home on an agricultural property sued due to a contaminated water supply and an overflowing septic tank/leach field system. Determined that the property owner’s house was being served with the same water supply that was claimed to be contaminated, that no health official had seen the septic tank overflow, and that the surface discharge was from a kitchen sink that the tenant had plumbed to flow onto a nearby field.
