The 1940's to Mid-60's on My Family Farm

The 1940's to mid-60's on my family farm in Dubuque County , Iowa was not a time of particularly great environmental concern on any public level.  The USDA was beginning to make strides in erosion control with such practices as crop rotation programs, but water quality issues were not a subject of discussion among most farmers or the general public.  The few limestone sinkholes and the more numerous depressions from old lead mines in our Fayette and Dubuque soils were more of a nuisance to farm around than they were a concern for potential groundwater contamination.  Although numbers of hogs and dairy cows were minute by today's confinement system standards, the hog lot and dairy barn with their piles of manure were often dangerously close to these sinkholes and lead mines as well as close to the spring fed, limestone-based stream that dissected the farm.  No one deliberately polluted the ground water, but unfortunately out of economics and ignorance we used those areas, as well as eroded ravines, as receptacles for dead animals, household garbage, oil, etc.  We have a tendency to blame farmers for a great share of our water quality problems, but even back then, with a lack of strict regulations on garbage disposal, these same types of areas next to farm to market roads became sources for dumping by urbanites as well.
