Potential Risks

Land application of biosolids has proven a cost-effective method of waste disposal by beneficially recycling organic matter and nutrients and improving soil quality; however, it may also pose potential threat to the environment and human health. The purpose of this paper is to provide information on recent research progresses and regulation efforts regarding land application of biosolids, including forms and types and nutrient values of biosolids, environmental and health concerns, and related best management practices (BMPs) of biosolids application, with emphasis on its land application in agriculture. More research and regulations are expected to minimize potential risks of biosolids land application, especially its long-term impacts.

Water Treatments

Land application of recycled water is currently practised in many countries as an alternative to discharge directly into inland and coastal waters. In this field study, nitrogen (N) and phosphorus (P) availability in pasture plots that received recycled water was compared with that of plots which received single applications of superphosphate fertiliser (SSP). The treatments included recycled water applied continuously, recycled water applied alternately with fresh water, single application of SSP at the beginning of the experiment, and a non-amended control. Results from the study showed that the amount of N and P removed by pasture was significantly (P < 0.01) greater in plots that received both recycled water treatments than in the SSP-treated plot and the control. The amount of N (as nitrate and ammonium) leached below 1.0 m soil depth was significantly greater (P < 0.01) for the continuous recycled water treatment than the other treatments or the control. Nitrate was the dominant (>80%) form of N leached from all 4 treatments. In contrast to the findings for N, a greater proportion of applied P (47.9%) was leached below 1.0 m soil depth from the SSP-treated plots than from plots that received recycled water continuously (26.0%), alternately with fresh water (13.3%), and the control. Results from the study may be useful for developing best management practices for recycled water irrigation of pasture.

Negative Impacts

Abstract Compliance with 60 forestry best management practices (BMPs) in Maine was evaluated from a sample of 120 sites randomly selected from areas harvested during the period January 1, 1993 to December 31, 1994. The forestry BMPs were organized into six groups [haul roads, stream crossings, skid roads/trails, putting trails/roads to bed, log yards/landings, and streamside management zones (SMZs)]. Applicability of each practice was assessed at each site and compliance with applicable BMPs rated. Evidence of sediment movement was used as a measure of BMP effectiveness. Compliance with the various BMPs within each of the six groups ranged as follows: haul roads 34%-100%; stream crossings 31%-94%; skid roads/trails 49%-95%; putting trails/roads to bed 25%-88%; log yards/landings 53%-96%; and SMZs 42%-78%. Low levels of compliance per se may overstate the negative impacts in those cases where BMPs are applicable on a small number of sites. For example, compliance with the recommendation that water courses be forded only on hard bottoms and banks was low (54%) but was applicable to only 39 sites, affecting 21 of the 120 sites examined. Overall compliance was greatest for the BMPs related to yards and landings (81%) and was lowest for putting trails/roads to bed (54%). Compliance levels in Maine were similar to those reported in Vermont and Minnesota. Compliance tended to be higher for those BMPs associated with planning and layout of haul roads and skid trails, compared to those dealing with water diversion from long, unobstructed surfaces. Old roads pose a challenge. Many road systems in use today were constructed a decade or more ago by scraping surface soil down to the basal till generating low road surfaces bounded by high banks. Ditches slowly eroded and became ineffective in diverting water from the road surface. Corrective measures are expensive, and new water diversion ditches will disturb more of the area. This study supports the utility and effectiveness of commonly recommended BMPs in reducing erosion and sedimentation in Maine. When BMPs were used, sediment movement was eliminated completely or was largely restricted from surface waters. Numbers of sites at which appreciable sediment delivery to surface waters was associated with noncompliance of individual BMPs within each of the six categories are summarized as follows: haul roads 1-17 sites; stream crossings 0-17 sites; skid roads/trails 0-20 sites; putting trails/roads to bed 9-14 sites; log yards/landings 1-14 sites; and SMZs 1-9 sites. In total, noncompliance with at least one BMP was associated with a downstream sediment trail at 34 sites. North. J. Appl. For. 15(2):57-68.

The Look

Everyone enjoys the look of a nice, healthy lawn in a landscape. Not only do lawns increase the value of property, they help to cool the environment and reduce soil erosion. Most importantly, a healthy lawn reduces pollution resulting from stormwater runoff, because it is able to actively filter and trap sediment or pollutants that might contaminate ground or surface waters. It is very important that homeowners follow best management practices when maintaining their lawns so as to not cause pollution to Florida's water resources. For a happy, healthy, and environmentally friendly lawn, follow the tips outlined in this document. This document is Fact Sheet ENH979, one of a series of the Environmental Horticulture department, Institute of Food and Agricultural Sciences, University of Florida.
